Hierarchical Integration of System-of-Systems Models

Important results from the project

The project has developed a methodology that allows studying the constituent systems within a System-of-System, and map how they are linked to each other and how overarching needs are met. A Swedish Search and Rescue scenario has been used as a use case, and it has been showed how model fidelity and model computational costs can be matched depending on the SoS capabilities being investigated. To this end a framework has been developed, which uses ontologies and agent-based simulations to explore design alternative and predict their performance.

Expected long term effects

In addition to the theoretical results, the project has also developed concrete models and tools that can be employed within System-of-Systems studies. The project has also focused on how to analyze the very large amount of simulation data and how to graphically present analysis results to enable understanding the underlying complex trends. The results have been documented in international publications at conferences and in journals. Developed methods and tools have also been presented at Saab and have been employed within the internal FCAS project.

Approach and implementation

The consequences of the COVID-19 outbreak clearly impacted the project. The pandemic was unforeseen and there was no contingency plan at the start of the project for an event of such magnitude. The effects on project activities have thus been significant, but during 2021 the pace of progress increased again. There were plans and accepted scholarships for periods of visit at leading research teams, but these had also to be cancelled. Conferences were held in virtual form due to COVID-19 which also limited the chances of proficient feedback.
