    Lean and its impact on workplace design2013In: Proceedings of NES 2013, 45th Nordic Ergonomics & Human Factors Society conference, Iceland, August 2013, 2013Conference paper (Refereed)
    Abstract [en]

    Lean analyses and following corrections of workstations are typically performed reactively, i.e. solving problems that already exist. However, there are benefits of enhanced proactivity related to the consideration of lean and human factors, as this would reduce the need for updating workstations. The approach presented here utilises a company specific, reactive lean evaluation methodology, but applied proactively, in the workstation design phase. Results gave that many assessment items in fact can be proactively addressed. This way, ergonomic and lean workstations that support quality, performance and wellbeing for a diversity of workers, can be built right the first time.

    Supporting Attention in Manual Assembly and its Influence on Quality2010In: Proceedings of the 3rd Applied Human Factors and Ergonomics (AHFE) International Conference / [ed] Gavriel Salvendy, Waldemar Karwowski, Louisville: AHFE International , 2010Conference paper (Refereed)
    Abstract [en]

    Modern manufacturing information systems allow fast distribution of, and access to, information. One of the  main purposes with an information system within  manual assembly is to improve product quality, i.e. to ensure that assembly errors are as few as possible. Not only  must an information system contain the right information, it must  also  provide  it  at  the  right  time  and  in  the  right  place.  The  paper  highlights some of the concerns related to the design and use of information systems in manual assembly.  The  paper  describes  a  study  that  focuses  on  the  correlation  between active information seeking behaviour and assembly errors. The results are founded on  both  quantitative  and  qualitative  methods.  The  study  indicates  that  by  using simplified information carriers, with certain characteristics, the assembly personnel more easily could interpret the information, could to a higher degree be prompted (triggered) about product variants and could also be able to prepare physically and mentally   for   approaching   products   arriving   along   the   assembly   line.   These conditions  had  positive  influence  on  quality,  i.e.  gave  a  reduction  of  assembly errors.

    Ergonomics analysis in a virtual environment2007In: International Journal of Manufacturing Research, ISSN 1750-0591, Vol. 2, no 2, p. 198-208Article in journal (Refereed)
    Abstract [en]

    Simulation can support the design of an ergonomic workplace by enabling early assessment of ergonomic conditions in a virtual environment. An important feature is the possibility to study alternative solutions or the effect of improvements from an ergonomics perspective. To be able to conduct an efficient and reliable evaluation in a virtual environment, an objective analysis method is essential. Such an analysis method should be integrated in the simulation software, and support a company's everyday ergonomics work process. In order to gain from existing ergonomics knowledge within a company, the possibility to implement such wisdom in the current simulation software becomes important. This paper presents an implementation work done with the purpose of integrating an established ergonomics work process into a virtual environment. It describes the benefits of an ergonomics work process where simulation and evaluation at early stages of a design process are key factors. The paper will also describe the integration process, i.e., the technical issues as well as the change in work methods.

    Reduction of ergonomics design flaws through virtual methods2007In: Proceedings of the 39th annual Nordic Ergonomic Society Conference, Lysekil, Sweden, October 1-3, 2007 (NES 2007) CD-ROM, Nordic Ergonomics Society, 2007Conference paper (Refereed)
    Abstract [en]

    A work method for product and production system development that includes virtual methods for ergonomics analysis is presented and argued.The proposed work method is described and illustrated with an example,which the authors believe shows how a virtual work method can contribute to a better workplace design, and thereby, if utilised, would have prevented some of the design flaws that existed in the actual final product design in the example. This paper will also present the outcome, gain, and setbacks that are connected to the use of virtual work analysis methods within a design process.

    Kundlojalitet: En kvalitativ konsumentstudie2007Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    För en butiks överlevnad har vikten av lojalitet kommit att bli en allt mer central punkt då konkurrensen inom olika branscher ständigt ökar. Då det finns en strävan för företag att behålla sina nuvarande kunder kan företaget, genom att skapa kundlojalitet, bidra till en högre lönsamhet. Det finns olika tillvägagångssätt för ett företag att använda sig utav för att uppnå lojalitet bland konsumenter, frågan är dock vad och vilka metoder som kan tänkas bidra till lojalitet. Beroende på vilken sorts produkt konsumenten söker ser de olika stegen i köpprocessen annorlunda ut då vikten av de olika stegen baseras på konsumenters engagemang kring en produkt. Utifrån denna bakgrund anser i det vara intressant att se om det finns några bidragande faktorer till skapandet av kundlojalitet gentemot en butik. Vi ställer oss därför frågan; Påverkar faktorerna i konkurrensmedelsmixen konsumenter till lojalitet gentemot en butik, och i sådana fall vilka faktorer? Är det någon skillnad mellan vilka faktorer som påverkar konsumenten till ökad lojalitet gentemot en butik när det gäller hög- respektive lågengagemangsprodukter? Vår frågeställning leder till syftet som lyder; Vi avser att beskriva vilken roll olika faktorer i konkurrensmedelsmixen har för skapandet av kundlojalitet. Denna beskrivning kommer att göras för hög- respektive lågengagemangsprodukter. För att besvara uppsatsens syfte har vi valt att använda oss utav kvalitativa intervjuer ur ett konsumentperspektiv genom en fokusgruppsintervju och individuella intervjuer. För att uppnå ett internt giltigt resultat valde vi att, bland de utvalda respondenterna, sätta samman gruppen utifrån olika demografiska egenskaper. Kontentan av denna studie är att det finns faktorer i konkurrensmedelsmixen som bidrar till lojalitet gentemot en butik. Dock visade resultatet av vår studie att faktorerna skiljer sig beroende på graden av engagemang bakom köpet.

    Bucklingsanalys av spannmålssilo2013Independent thesis Basic level (degree of Bachelor), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [en]

    Grains with varying humidity can be stored in square silos with wall elements consisting of corrugated sheet. When the stored grain is to be emptied from the silos it has tendency to stick to the walls, especially if humid, which means that the grain must be removed manually. To avoid this time-consuming process a flat sheet is mounted on the corrugated sheet to prevent the moist grain from sticking to the wall. If the same dimension on the corrugated sheet is used when the flat sheet is or is not mounted the walls may be subjected to buckling. This thesis is thus about how the wall elements shall be designed in order to prevent buckling. The silos that have been examined have a cross section of 3.0 x 3.0 m and 2.5 x 2.5 m respectively with wall elements consisting of only corrugated sheet or smooth sheet mounted on corrugated sheet. Furthermore, the silos got vertical walls with a height of 8.4 m consisting of ten sections. Calculations are made with wheat as the stored grain.

     

    To be able to dimension the wall elements the pressure is calculated for the different silos, using the Swedish and European standard Eurocode (2006), EN 1991-4 for pressure calculations in silos and tanks. To calculate the pressure the silos are assigned into action assessment class 1, since their capacity are less than a 100 tons, which further means that the unsymmetrical pressure can be ignored. The silos are also classified as slender. As the silos outlet consists of a square pyramidal hopper with centric outlet and a half internal angel of 45° an inner pipe flow occurs during emptying. This means according to Eurocode that the dimension shall be based on the pressure which occurs during filling. The horizontal and vertical pressure and the pressure made from the friction are calculated for the different cross sections.

     

    The CAD software Pro Engineer and the finite element extension Mechanica is used to model the current silos and perform analysis for stress and buckling. The models have four symmetry planes therefore only one eighth of the current structure is modeled, corresponding to half a wall element and half a pole. The models are created as shell models and boundary conditions are applied in all symmetrical planes and on the top and bottom of the pole. The structure of the silos is simplified since no screws or radius is modeled. The pressure calculated according to Eurocode is converted into forces and applied to the models. The whole structure is modeled in steel with yield strength of 180 MPa.

     

    The company’s older dimension standards are applied on the wall elements and analyzed. To investigate where to most critical areas for buckling occurs a buckling analysis based on a static analysis of the models is performed. The results from the buckling analysis for the silo wall element consisting of corrugated sheet with the width of 3.0 m shows that buckling occurs on the second bottom section at 72 % of the applied force. For the silo consisting of the same wall element but with the width of 2.5 m buckling occurs at the top section where the buckling force amounts to 62 % of the applied force. For the silos with wall elements consisting of plain sheet mounted on corrugated sheet buckling occurs at 3-4 % of the applied force for the two wall widths. Analysis show that the low values of buckling load on the plane sheet is a result from local buckling. In order to dimension the corrugated sheet to prevent it from buckling when the plane sheet is mounted a free body diagram is made for the corrugated sheet to obtain the acting forces. The buckling analysis of the corrugated sheet, with wall width 3.0 m, which is pressurized by the plane sheet shows that buckling occurs on the silos second bottom section. Buckling occurs at 59 % of the applied force for the silo with wall width of 2.5 m buckling occurs at 51 % of the applied force on the silo top section.

     

    Since the goal is that the corrugated sheets are not to be subject to buckling, the thickness of the sheets is iterated until the buckling force is equal to at least 110 % of the applied force. This generates an increased thickness for the lower four sections for the silo with wall element consisting of corrugated sheet with wall width of 3.0 m. For the silo with the same wall elements but with a wall width of 2.5 m, the dimensions of the top two sections need to increase. Regarding the silos with wall elements consisting of plane sheet mounted on corrugated sheet an increase in dimension is needed for the corrugated sheet for the five lowest sections for the wall width of 3.0 m.

     

    With a wall width of 2.5 m the same dimension can be used as when the silo wall elements consist of only corrugated sheet. If the plane sheet is not to be exposed for buckling the thickness of the sheets needs to be increased from between 5.5 mm and 1.5 mm. All calculations of the sheet dimensions are obtained by a conservative thinking which means that the company’s older dimensions may be correct. However, the resulting dimensions are reasonable for the corrugated sheets.

    3D Model Driven Distant Assembly2012Independent thesis Basic level (degree of Bachelor), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Today, almost all factories use robots to a certain extent. In particular, automated assembly operations are common in modern manufacturing firms. However, current industrial applications require a pre-knowledge of assembly parts, their locations as well as the paths that they should follow during the assembly process.

    This research introduces a remote assembly control system, which gives the operator access to the robot at any time and any location as long as there is an Internet access. In addition, the remote assembly control uses a user-friendly interface which is easy and quick to use. An operator does not need great knowledge before using the web portal for the remote assembly control. On the contrary, using robot programming software would require the operator spending more time to learn specific skills. The remote assembly is also useful in risky situations in which the operator must keep a distance from the work place of the robot.

    The main objective of this project is to design a web-based system that can provide the ability for remote operators to assemble objects in a robotic cell using 3D models of those objects in a virtual environment. The system consists of an industrial robot and a network camera connected to an application server. Using the user interface and the camera, a remote operator can take some snapshots of the real objects in the robotic cell and the system will construct the 3D models of these objects. Consequently, the operator can assemble the real objects using the equivalent 3D models via an existing Wise-ShopFloor virtual environment.

    The scope of the project includes:

    • Capturing the real objects with a camera mounted beside the gripper of the robot. The position of the camera gives the system more flexibility for taking the snapshots from different angles.
    • Analysing the snapshots using different filters in order to identify the silhouettes of the objects. These silhouettes will be labelled to help distinguishing the different objects.
    • Constructing 3D models of the objects. This will be done by constructing pillars from the labelled silhouettes of the top view of the objects. These pillars will be trimmed with the silhouettes obtained from snapshots in different angles, until the pillars represent the objects with the needed accuracy.
    • Integrating the models into the Wise-ShopFloor virtual environment. This environment can be executed in a web browser.
    • Updating the objects in the virtual environment according to the assembly operations.

    Since assembly only needs picking and placing objects, the image processing and the 3D modelling do not need as high quality as it would need for other tasks, such as welding. In addition, the operator may be anywhere as long as an Internet access is provided. The Internet connection does not need to be in broadband because the system consumes a limited bandwidth for receiving snapshots from the camera and sending assembly instructions to the robot.

    The results of this project will allow the operator to work away from dangerous environments, therefore helping to improve safety. This research can also help improving the adaptability of industry in ad-hoc assembly operations. Besides, the use of the web for the remote assembly can save cost and time in operator training and special-purpose software purchasing. Remote assembly is expected to become an important research area with unlimited application potentials in the future in distributed manufacturing.

    Adhesive joining for crashworthiness: material data and explicit FE-methods2008Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Today, crash simulations replace crash testing in the product development phase in theautomotive industry. High quality simulations enable shorter product development time andhigher competitiveness. However, increasing requirements regarding emissions andcrashworthiness are demanding optimised material choice in the parts constituting the carbody structure. Lightweight materials are becoming frequently used. Joining dissimilarmaterials is difficult using common joining techniques like spot welding. To this end,adhesive joining is currently gaining popularity not only due to the ability to join dissimilarmaterials, joint integrity and structural stiffness both increase by the use of adhesive joining.Moreover, the number of spot welds may be reduced in hybrid joints.In this thesis, adhesive joints are studied with respect to crashworthiness of automotivestructures. The main task for the adhesive is not to dissipate the impact energy, but to keep thejoint integrity so that the impact energy can be consumed by plastic work of the basematerials. Fracture of adhesives can be accurately modelled by cohesive zones. The dynamicbehaviour of finite element structures containing cohesive zones is studied using a simplifiedstructure. An amplified strain rate is found in the adhesive as compared to the base material.The cohesive zone concept is used in the development of a 2D interphase element. Theaccuracy and time step influence of the interphase element is compared to solutions based oncontinuum element representation of the adhesive. The interphase element is found to predictfracture of the adhesive joint with engineering accuracy and has a small effect on the timestep of the explicit FE method.The cohesive laws for use in the material models of the adhesive have been determined usingdedicated test methods. The double cantilever beam specimen and the end notched flexurespecimen are used with inverse methods to determine cohesive laws in peel and shear,respectively. The cohesive laws are determined for varying temperature, strain rate andadhesive layer thickness. A built up bimaterial beam is designed for testing and simulation ofjoints consisting of bolts, adhesives and combinations of bolts and adhesives, i.e. hybridjoints. The model of the hybrid beam developed was found to be able to predict results fromimpact tests, quantified as maximum load and deformed shape of the beam.

    Impact Simulation of Adhesively Joined Structures2006Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    The development of competitive and crashworthy automotive car bodies has reached so far that the manufacturers no longer rely on mono-material steel structures. Improved strength/weight performance may be achieved by using optimal material in each part of the car structure, leading to bi-material joints and ruling out spot welding; the common joining method during the past half century of automotive history. Adhesive bonding is an attractive joining method, not only capable of managing dissimilar materials, but also capable of improving stiffness and strength in monomaterial structures. Moreover, the joints do not need additional sealing and there may be cost savings using adhesive bonding. Impact simulation of car structures is mostly performed using an explicit FE-method. This method has an inherent stability criterion: the time step used may not exceed the stable time step, or critical time step, Δtc. In this thesis, a simplified cohesive zone model is studied. It is implemented into an explicit FE-code and compared to a closed form solution. The FE-solutions agree with the closed form solutions. It is found that the evolution of damage in the adhesive layer may stop under certain conditions that are likely to occur in a real structure. It is shown that an explicit FE-analysis with a “large” time step is more prone to give immediate rupture. Thus, the method is conservative. An interphase element formulation is derived for a 2D-adhesive joint model, joining beam adherends. It is shown that the mass matrix of the interphase element gives a small contribution to the mass matrix of the structure. However, this contribution is positive for the numerical stability of the explicit FE-method and it is recommended to keep this matrix in the analysis. Moreover, it is concluded that the contribution of material damping of the adhesive layer can be neglected as compared to the effects of plasticity of the adherends. The interphase element formulation is used to analyse the Double Cantilever Beam specimen. The results are compared to an alternative model using continuum elements. The comparison shows substantially faster convergence and shorter execution time for the interphase formulation. A rough estimate indicates fifteen times shorter execution time using the interphase elements in a realistic structure.

    Explicit FE-formulation of interphase elements for adhesive joints2008In: International Journal for Computational Methods in Engineering Science & Mechanics, ISSN 1550-2287, E-ISSN 1550-2295, Vol. 9, no 5, p. 288-299Article in journal (Refereed)
    Abstract [en]

    The potential of adhesive bonding to improve the crashworthiness of cars is attracting the automotive industry. Large-scale simulations are time consuming when using the very small finite elements needed to model adhesive joints using conventional techniques. In the present work, a 2D-interphase element formulation is developed and implemented in an explicit FE-code. A simplified joint serves as a test example to compare the interphase element with a straightforward continuum approach. A comparison shows the time-saving potential of the present formulation as compared to the conventional approach. Moreover, the interphase element formulation shows fast convergence and computer efficiency.

    Influence of temperature and strain rate on cohesive properties of a structural epoxy adhesive2009In: International Journal of Fracture, ISSN 0376-9429, E-ISSN 1573-2673, Vol. 155, no 2, p. 155-166Article in journal (Refereed)
    Abstract [en]

    Effects of temperature and strain rate on the cohesive relation for an engineering epoxy adhesive are studied experimentally. Two parameters of the cohesive laws are given special attention: the fracture energy and the peak stress. Temperature experiments are performed in peel mode using the double cantilever beam specimen. The temperature varies from −40 to + 80°C. The temperature experiments show monotonically decreasing peak stress with increasing temperature from about 50 MPa at −40°C to about 10 MPa at + 80°C. The fracture energy is shown to be relatively insensitive to the variation in temperature. Strain rate experiments are performed in peel mode using the double cantilever beam specimen and in shear mode, using the end notch flexure specimen. The strain rates vary; for peel loading from about 10−4 to 10 s−1 and for shear loading from 10−3 to 1 s−1. In the peel mode, the fracture energy increases slightly with increasing strain rate; in shear mode, the fracture energy decreases. The peak stresses in the peel and shear mode both increase with increasing strain rate. In peel mode, only minor effects of plasticity are expected while in shear mode, the adhesive experiences large dissipation through plasticity. Rate dependent plasticity, may explain the differences in influence of strain rate on fracture energy between the peel mode and the shear mode.

    An explicit FE-model of impact fracture in an adhesive joint2007In: Engineering Fracture Mechanics, ISSN 0013-7944, E-ISSN 1873-7315, Vol. 74, no 14, p. 2247-2262Article in journal (Refereed)
    Abstract [en]

    Dynamic fracture of an adhesive layer in a structure is analysed. The structure represents some specific properties of an automotive structure and is simple enough to allow for closed form solutions obtained by the method of characteristics. These solutions are compared to results of explicit FE-analyses. The FE-solutions agree with the closed form solutions. Damage is included in the FE-model. Three constitutive models of the adhesive layer are used. It is shown that an amplification of the strain rate is achieved in the adhesive layer. It is also shown that an artificially increased flexibility of the adhesive in an aluminium structure gives only minor influences of the general behaviour. In some load cases, the adhesive layer will experience repeated loading/unloading. It is shown that in these cases an explicit FE-analysis with a “large” time step is more prone to give immediate rupture. Thus, the method is conservative.

    Dynamic testing and simulation of hybrid joined bi-material beam2010In: Thin-walled structures, ISSN 0263-8231, E-ISSN 1879-3223, Vol. 48, no 8, p. 609-619Article in journal (Refereed)
    Abstract [en]

    A specimen is developed for real-like low velocity impact testing of bi-material joint configurations. Six different joint configurations are analysed. Two engineering adhesives are evaluated with and without discrete mechanical fasteners, i.e. adhesive and hybrid joints. Experiments and simulations are performed. The simulations are performed using adhesive cohesive finite elements. Simulations show good agreement with experiments in impact energy and overall deformation mode. The histories of applied load vs. load-point deflection show reasonably good correlation. The results show that the impact energy consumption depends on the joint integrity. A threshold value for the fracture energy of the adhesive seems to exist. Beneath this value, adhesive and discrete fastener work together increasing the impact energy capacity. Above this value the discrete fastener has a negative effect, and may be regarded as a stress concentration.

    Influence of Layer Thickness on Cohesive Properties of an Epoxy-Based Adhesive: An Experimental Study2010In: The journal of adhesion, ISSN 0021-8464, E-ISSN 1563-518X, Vol. 86, no 8, p. 814-833Article in journal (Refereed)
    Abstract [en]

    Cohesive laws are determined for different layer thicknesses of an engineering adhesive. The shape of the cohesive law depends on the adhesive layer thickness. Of  the  two  parameters  of  the  cohesive  law—the  fracture  energy  and  thestrength—the fracture energy is more sensitive to thickness variation than the strength. The fracture energy in peel mode (Mode I) increases monotonically as the thickness is increased from 0.1 to about 1.0 mm. At an adhesive thickness of 1.5 mm, the fracture energy is slightly lower than for a 1.0 mm adhesive thickness, indicating a maximum between 1.0 and 1.5 mm. In shear mode (Mode II), the thickness dependence is not as strong, but an increasing trend in fracture energy with increasing adhesive thickness is evident. A slight decrease in strength with increasing adhesive thickness is found in both loading modes.

    Utveckling av viktskivor, viktlås och viktställ för professionell gymverksamhet2008Independent thesis Basic level (degree of Bachelor), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [sv]

    Denna rapport behandlar ett examensarbete inom integrerad produktutveckling som utfördes av Andreas Carlsson och Marcus Ronnheim vid Designingenjörsprogrammet på Högskolan i Skövde vårterminen 2008. Examensarbetet var att utveckla Casall Sports Products viktskivor, viktlås samt viktställ för bodypumpviktskivor. Bakgrunden till uppdraget var att Casall tyckte att deras, redan nämnda produkter, var föråldrade och behövde ett nytt utseende samt att viktstället saknade vissa fördelaktiga funktioner. Rapporten beskriver hela produktutvecklingsfasen från förstudie till produktionsritningar.

    Under förstudien gjordes bl.a. en marknadsundersökning och användarintervjuer, detta resulterade i en kravspecifikation. Idégenereringsfasen resulterade i flera s.k. mood boards som ett flertal idéer kring viktskivor och viktställ togs fram utifrån. Konceptutvecklingen handlade mycket om att bestämma en exakt storlek för produkterna och att bestämma material samt att göra CAD-modeller och ritningar.

    Resultatet blev att internationella viktskivor, pumpviktskivor samt viktställ gjordes helt färdiga. Skolvikter och viktlås stannade vid koncept, dock togs ändå ritningar togs fram för viktlåset.

    Förlåtelse: Förlåta fullt ut2009Independent thesis Basic level (degree of Bachelor), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    I ordet förlåtelse ingår det många olika tolkningar beroende på vem det är som definierar. I vårt arbete har vi valt att inrikta oss på förhållandet mellan offret och förövaren när det gäller grova gärningar som mord, övergrepp och misshandel. Vår frågeställning är om det är möjligt att förlåta onda gärningar fullt ut? Kan ett offer förlåta en förövare fullt ut som genom sina onda handlingar har orsakat offret lidande? Finns det någon rättvisa med tanke på den obalans som uppstår genom ondskefulla gärningar. Vi har valt att utgå ifrån rättvise teorin eftersom samhället har en rättvisa som grund när det gäller brott och straff. Vi har använt kvalitativmetod och har valt att göra två informantintervjuer med personer som i sitt dagliga arbete kommer i kontakt med förlåtelse. Vi intervjuade även personer som hade genomgått en förlåtelseprocess och vi analyserade intervjuerna utifrån vår definition på förlåtelse fullt ut som är

    … att människor inte ska uppleva någon aggression, bitterhet, rädsla, sårbarhet, ångestfylldhet till förövaren/gärningen och återfått förtroendet till förövaren när de har förlåtit fullt ut.

    Förlåtelse, försoning, hämnd och rättvisa är de begrepp som vi har funnit spegla respondenternas syn på området. Enligt vår förförståelse anser vi att det inte går att stryka ett streck över eller glömma svåra kränkningar. Vi menar att det inte går att förlåta fullt ut.

    Mellanchefens arbetsmotivation: En kvalitativ studie kring arbetsmotivation utifrån mellanchefens perspektiv2013Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Every day thousands of middle-level managers work in our Swedish grocery stores with the goal to reach set department targets through optimal control. At the same time as the staff require their work to be satisfied, and at the same time the customers must be in focus and attention to. This reality places high demands on the shop to have middle-level managers who experience work as motivating, as motivated individuals tend to perform better than non-motivated individuals. This qualitative study addresses the motivation among middle-level managers in Swedish grocery stores and intends to investigate factors that may contribute to the motivation of these managers. This study shows that factors such as responsibility, development, challenging tasks, feedback and the relationship to other colleagues are a potential key elements of the respondents´ perceived motivation at work. The results of this study cannot be generalized, but can nevertheless be seen as an important and relevant contribution in the store manager´s efforts to devise incentives and incentive instruments for middle-level managers in grocery stores.

    Atmosfär och tillgänglighet: är det viktigt för en handelsplats?2008Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Shopping har idag blivit ett fritidsnöje bland konsumenterna och när konsumenterna går till olika shoppingcentrum är det lika viktigt med en bra upplevelse som med själva handlandet. Det läggs ned mycket tid på att få rätt butiksmix i stadskärnan och externa köpcentrum. Under de senaste årtionden har externa köpcentrum vuxit fram och blivit en konkurrens för stadskärnan. Det är därför viktigt att stärka upplevelsen för konsumenten och locka dem till sig. Viktigt är att känna till kundernas behov och önskemål för att lyckas överleva och konkurrera mot de olika köpcentrumen.

    Uppsatsen har som mål att ta reda på vad det är konsumenten vill uppleva vid shoppingen, och inte själva handlandet i sig. Vi vill få fram faktorer som kan beskriva hur en handelsplats blir attraktiv med avseende på atmosfär och tillgänglighet. Med andra ord hur ser konsumenten på atmosfären och tillgängligheten runt själva stadskärnan och det externa köpcentrumet. Valet föll på en kvalitativ undersökning som går på djupet, den undersökningsmetod som var bäst lämpad för ändamålet blev fokusgrupper. Med fokusgrupper ges uttömmande svar då det diskuteras både fördelar och nackdelar med olika centrum. Grupperna delade vi in i ungdomar, barnfamiljer och parförhållanden utan barn, grupperingarna gjorde vi med tanke på att de troligen har olika värderingar beroende på vilket stadie de är i livet.

    Det som kan utläsa av undersökningen är att atmosfär har en stor betydelse för både stadskärnan och externt köpcentra speciellt när konsumenterna vill kombinera handlandet och umgänget med vänner och familj. De viktigaste faktorerna som har kommit fram är att torget spelar en stor betydelse och de efterfrågar fler aktiviteter och gröna oaser med bänkar där man kan sitta i lugn och ro och koppla av. Det visade sig ha stor betydelse var någonstans i livet konsumenten befinner sig. De som lever utan barn tänker mer på det kvalitativa och njutningsperspektivet. Medan de som har barn tänker mer på att det ska vara enkelt att handla när barnen är med. Ungdomarnas syn var att ha någonstans att ”hänga på”. Tillgänglighet däremot är något som tas för givet och gav inte så stora diskussioner. Det som gavs mest uppmärksamhet var Öppettider, Utbud av butiker samt Restauranger, Caféer och toaletter. En bra kommentar som vi fick av en respondent var:

    ”I externa köpcentrum går jag om jag vill ha effektiv shopping och till en stadskärna går jag om jag vill ha ett socialt umgänge”

    Design av lättöppnad färdigmatsförpackning: Inriktning hållbar utveckling2013Independent thesis Basic level (degree of Bachelor), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [en]

    A development of an environmentally friendly, ready meals packaging, that is easy to open for people suffering from rheumatoid arthritis, has been performed in cooperation with CC Pack in Tibro. The package is intended for use in elderly care home services. The development work was mainly done by focus group surveys and tests of function models. A life cycle analysis with reference in the current plastic trays used in home care in Skövde was conducted to find out which of the two final concepts was the most eco-friendly. Evident in interviews and site visits was that a rounder and more colorful packaging was desired. A simple oval tray with a hard cardboard flap solved the problem of opening difficulties, both by the position of the hard flap and also with an elongated shape.

    Informed Design of Educational Activities in Online Learning Communities2012In: Informed Design of Educational Technologies in Higher Education: Enhanced Learning and Teaching / [ed] Anders D. Olofsson & J. Ola Lindberg, IGI Global, 2012, p. 118-134Chapter in book (Refereed)
    Abstract [en]

    The aim of this chapter is to sketch design implications for organizing online educational activities in higher education that will intentionally engage medical students and professionals in the field together. When using an online forum, which is already embedded in the work practice, participants can build an online learning community (OLC) to discuss specialist subjects. This chapter is based on findings derived from a larger case study about participation in a professional OLC in general medicine. The proposal of an educational activity will complement numerous online activities with a more structured form of learning. As long as participants are challenged in learning about the specialist subject, they will contribute to the collective account. Online participation can be one way to foster students in becoming doctors. Together with qualified professionals, medicine students can create and sustain relationships over their professional careers.

    HADRIAN: Fitting Trials by Digital Human Modelling2009In: Digital Human Modeling: Second International Conference, ICDHM 2009 Held as Part of HCI International 2009 San Diego, CA, USA, July 19-24, 2009 Proceedings / [ed] Vincent G. Duffy, Springer Berlin/Heidelberg, 2009, p. 673-680Conference paper (Refereed)
    Abstract [en]

    Anthropometric data are often described in terms of percentiles and too often digital human models are synthesised from such data using a single percentile value for all body dimensions. The poor correlation between body dimensions means that products may be evaluated against models of humans that do not exist. Alternative digital approaches try to minimise this difficulty using pre-defined families of manikins to represent human diversity, whereas in the real world carefully selected real people take part in 'fitting trials'. HADRIAN is a digital human modeling system which uses discrete data sets for individuals rather than statistical populations. A task description language is used to execute the evaluative capabilities of the underlying SAMMIE human modelling system as though a 'real' fitting trial was being conducted. The approach is described with a focus on the elderly and disabled and their potential exclusion from public transport systems.

    Upplevelsen av HRM praxis i Skövde kommun: Medarbetares handlingsmönster utifrån ett psykologiskt kontrakt2011Independent thesis Basic level (degree of Bachelor), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Den innevarande studien utforskar hur enhetschefer och avdelningschefer i Skövde kommun upplever sin arbetssituation utifrån personalchefens arbete med Human Resource Management (HRM) praxis. Fokus är att utifrån upplevelsen undersöka vilka indikatorer som föreligger för ett psykologiskt kontrakt och hur det kan inverka på medarbetarnas beteende. Teorin om mentala schemata applicerades slutligen på resultatet och illustrerades i en överskådlig modell av forskningsområdet. Utifrån en kvalitativ undersökningsmetod har HRM praxis i Guest modell av HRM (1997) format forskningsprocessen. Semi-strukturerade intervjuer genomfördes på ett urval av nio respondenter. Utifrån en hermeneutisk analys visade resultatet ett positivt psykologiskt kontrakt överlag vid utvecklings- och utbildningsmöjligheter, förtroende, trygghet och flexibilitet, medan studien lämnar förbättringspotential vid arbetsbelastning, lön, friskvård och riktlinjer.

    Design of an Information Carrier Device for a Decision Support System2012Independent thesis Basic level (degree of Bachelor), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [en]

    Automation   in   manufacturing   leads   to   produce   faster   but   it   also   increases   level   of information and relationship between parts. That makes more dificult to manage the work of operators in the manufacture chain to keep productivity high. Furthermore, manual assembly still  plays  a  vital  role  in  most  of  the  factories  all  over  the  world.  Hence  the  importance  of implementing  an  efficient  Decision  Support  System  which  helps  operators  to  make  right decisions. This project approaches to the design of a device to get information to operators. The project belongs to the University of Skövde and it is carried out in cooperation with Volvo Cars.  In the first stages of the project diverse information is gathered through the literature review and  market  research.  Literature  review  approaches  to  manufacturing  organization,  mobile information  in  manual  assembly  and  ergonomics.  Market  research  inquire  about  handheld devices. Also requirements from operators and environment are adressed. Next stages focus on the generation of ideas to hand in the information to operators. Diverse methodology was used  such  as  brainwriting  or  morphological  chart,  leading  to  three  different  concepts.  The PNI  method  was  employed  to  select  the  best  one.  It  consists  of  using  handheld  devices against  paper  sheets  or  wider  screens.  Then,  three  kind  of  handheld  devices  were  thought. Moodboards  and  brainwritings  were  employed  to  explore  shapes  and  functions.  They  were presented  to  coordinators  in  the  factory  and  one  of  them  was  selected  to  be  further developed.  Mockups  of  different  sizes  were  constructed  and  more  drawings  specified  the dimensions in order to build a CAD model. The final product is small to be easily carried with a wide screen and a stylus to facilitate interaction. Battery ensures withstanding work shifts and components are designed to favor maintenance tasks. The final product was built using CAD  software  and  printed  on  3D.    Materials,  manufacturing  methods  and  technology  have been  reviewed  to  ensure  viability.  Finally,  last  chapters  discuss  about  diverse  topics concerning this project such as ethical, enviromental or economical   issues. Further  work is proposed, too.

    En identitet med rötter utan jord: En kvalitativ studie om hur svenskfödda assyriska ungdomar upplever och skapar sin identitet.2009Independent thesis Basic level (degree of Bachelor), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Uppsatsens vill belysa assyriska ungdomars identitetsskapande och hur detta utförs med två olika kultursystem, och dessutom visas skillnader mellan könsrollerna. Urvalet avgränsas till svenskfödda assyriska ungdomar i 18 - 25 årsåldern. Dessa har oftast levt med en kollektivistisk kultur och en individualistisk kultur redan i primär socialisation. Tidigare forskning som har relevans för uppsatsen presenteras och handlar om assyriska ungdomars livssituation, assyriska genusroller och invandrarungdomar i Sverige. Teoretisk utgångspunkt för uppsatsen är symbolisk interaktionism, med teorier runt socialisationsprocessen, social identitet samt etnisk minoritet i kulturmöte. Metoden för undersökningen är kvalitativa semistrukturerade intervjuer. Detta tillvägagångssättets för - och nackdelar diskuteras och genomförande, etiska principer och valet av fem respondenter förklaras. Intervjuresultat ges i ett eget avsnitt för att visa tendenser och mönster som respondenterna uppvisar i intervjumaterialet. Dessa resultat diskuteras vidare genom att de kopplas till teori och tidigare forskning i ett sista kapitel. Uppsatsen avrundas med egna reflektioner och förslag på framtida forskning.

     

    Keywords: Identity, culture belong, Assyrian youths, ethnical minority.

    Father's Experiences of Shared Parental Leave in Sweden2007In: Recherces sociologiques et antropologiques, Universite catholique de Lovain , 2007, p. 9-25Chapter in book (Other academic)
    Abstract [en]

    Since the introduction of the Swedish parental leave reform in 1974, fathers have had the same rights to use parental leave as mothers. Between 2000 and 2003, a research project at the Department of Sociology, University of Gothenburg, focused on fathers who had taken more than four months of paid parental leave. The approach of the study was mainly qualitative, based upon a combination of a survey and interviews. A majority of the fathers who answered the questionnaire had been the main caregivers for their children during their parental leave. During the interviews many of the men described their mothers as role models for their fatherhood. The men also described their own partner as both anxious to get back to her work after her own parental leave period and convinced of the importance of a nurturing father. An early decision to take part of the parental leave probably made it easier for the men to reach workplace agreements. Most of the men described themselves as both nurturing fathers and as sharing housework equally. They stressed the importance of being alone with their child during a long period, to be able to develop a deep relationship with their child.

    In-transit distribution as a strategy in a global distribution system2011In: International Journal of Shipping and Transport Logistics, ISSN 1756-6517, E-ISSN 1756-6525, Vol. 3, no 2, p. 198-209Article in journal (Refereed)
    Abstract [en]

    Distribution has become a key factor in today’s logistics system due to companies’ desires to achieve considerable economies of scale in production, achieved by focused factories, as well as customers’ demands for shorter lead-times and customer adapted products. The purpose of this research is to investigate if the in-transit distribution strategy may offer companies a competitive advantage and may be used as a complement to the centralised distribution strategy and/or the decentralised distribution strategy. This study shows that the in-transit distribution strategy can give major competitive advantages by offering rather short lead-times for customers without having to store products locally in warehouses. This, in turn, gives lower warehousing costs, lower tied-up capital, a less interrupted manufacturing, and steady and continuous production volumes. In order to be successful with this strategy, it takes good planning, working closely with customers, good market knowledge, and an enterprise resource planning (ERP) system that is able to support the strategy sufficiently. Among these factors, low variation in demand as well as manufacturing output is required, and furthermore distribution lead time needs to be predictable.

    Supply Chain Planning in Automotive Sector: Swedish Case Study2011In: Conradi Research Review, ISSN 1459-0980, Vol. 6, no 2, p. 33-54Article in journal (Refereed)
    Abstract [en]

    This research aims to enhance the current level of knowledge from supply chain planning (SCP) by analyzing the importance of collaboration, information exchange and a supporting information system in its successful execution. These are examined through a case study from international manufacturing company, which operates in automotive industry with its global manufacturing network. Research reveals that collaboration is a complex and important issue of SCP, and occurs simultaneously in vertical and horizontal dimensions. It is important to select strategic partners and to develop a structured work processes and routines. The main objective of collaboration is to determine common goals and objectives and to facilitate the exchange of information; these together drive the performance of a supply chain higher. A sufficient information system supporting the SCP is vital to facilitate collaboration, and information exchange between the different supply chain participants. However, currently in the case company quite many phases of SCP are completed without appropriate and integrated information systems and the process itself contains several manual phases.
