Abstract [en]

This paper provides a schematic, systematic and structured approach todeveloping Bayesian belief networks to assess risks in contexts dened by activities.The method ameliorates elicitation, specication and validation of expert knowledgeby reusing a schematic structures based on reasoning of risks based on the temporal motivationaltheory. The method is based on earlier work that took a rst signicant steptowards reducing the complexity of development of Bayesian belief networks by clusteringand classifying variables in Bayesian belief networks as well as associating the processwith human deciions making. It may be possible to reduce the role of a facilitiatoror even remove the facilitator altogether by using this method. The method is partiallyvalidated and further work is required on this topic.

Abstract [en]

Using hyperglycemia as an example, we present how Bayesian networks can be utilized for automatic early detection of a person’s possible medical risks based on information provided by un obtrusive sensors in their living environments. The network’s outcome can be used as a basis on which an automated AMI-system decides whether to interact with the person, their caregiver, or any other appropriate party. The networks’ design is established through expert elicitation and validated using a half-automated validation process that allows the medical expert to specify validation rules. To interpret the networks’ results we use an output dictionary which is automatically generated for each individual network and translates the output probability into the different risk classes (e.g.,no risk, risk).

Abstract [en]

We use data-generated models based on data from experiments of an ocean-going vessel to study the effect of optimizing fuel consumption. The optimization is an add-on module to the existing diesel-engine fuel-injection control built by Q-TAGG R&D AB. The work is mainly a validation of knowledge-based models based on a priori knowledge from physics. The results from a simulation-based analysis of the predictive models built on data agree with the results based on knowledge-based models in a companion study. This indicates that the optimization algorithm saves fuel. We also address specific problems of adapting data to existing machine learning methods. It turns out that we can simplify the problem by ignoring the auto-correlative effects in the time series by employing low-pass filters and resampling techniques. Thereby we can use mature and robust classification techniques with less requirements on the data to demonstrate that fuel is saved compared to the full-fledged time series analysis techniques which are harder to use. The trade-off is the accuracy of the result, that is, it is hard to tell exactly how much fuel is saved. In essence, however, this process can be automated due to its simplicity.

Abstract [en]

A trend over the past years is that simulation systems for training are being connected in simulationnetworks, allowing the interaction of teams spread in distributed sites. By combining interconnected simulation systemsthe simulation complexity increases and may affect time-critical simulation tasks in a negative way. As a consequence,the training simulation objectives may not be met. The same problem may occur when performing, for example, missionrehearsal on site, since available computation resources are usually very limited in this scenario, or for a joint firesscenario, where the large and complex functional chain (including intelligence, C2, forward observer, pilots, etc.) mayoverload existing resources. In this work, the technique of imprecise computation in real-time systems (ICRS) topreserve time-critical simulation tasks is presented. The ICRS technique allows time-critical tasks to produce quickersolutions for approximate results and saves computational resources. This paper discusses the main advantages of theICRS technique by a review of the commonly used optimization concepts built upon imprecise computation field. Thepaper ends with presenting a work-in-progress: an architectural solution for aligning ICRS with the High LevelArchitecture (HLA), standardized as the IEEE 1516-series.

Abstract [en]

In this work, we raise three critical questions that must be investigated to ameliorate composability ofvirtual simulation models and to enable adoption of systematic and stringent real-time techniques toenable more scalable simulation models for virtual and constructive simulation. The real-time techniquesin question enable us to separate between policies and mechanisms and, thus, the simulation engine candecide dynamically how to run the simulation given the existing resources (e.g., processor) and the goalsof the simulation (e.g., sufficient fidelity in terms of timing and accuracy). The three critical questionsare: (i) how to design efficient and effective algorithms for making dynamic simulation model designdecisions during simulation; (ii) how to map simulation entities (e.g., agents) into (real-time) tasks; and(iii) how to enable a divide and conquer approach to validating simulation models.
