Theme 3 US Workshop

 

TAMS4CPS held its third US workshop on 10th and11th December 2015 at Purdue University, West Lafayette, US. The workshop provided an opportunity for around 10 US-based contributors and a number of EU-based facilitators to discuss latest developments and future research needs in CPS.

The workshop was the third in a series that aim to identify collaboration opportunities between the US and EU. Each workshop focuses on a theme in the area of modelling and simulation for CPS, and will consist of activities to:

  • introduce EU and US perspectives on the state of the art, strengths and weaknesses, and vision;
  • identify and prioritize trends and drivers, markets, technologies and enablers in the field;
  • elicit “test cases” (instances of CPSs and CPS design challenges) that can be used to benchmark modelling and simulation products (methods, tools, etc.) against the state of the art and against each other;
  • identify research collaboration priorities and implementation plans.

 

This workshop focused on Theme 3 of TAMS4CPS Real time modelling for autonomous, adaptive and cooperative Cyber-Physical Systems. This theme is concerned with models that can be used to control dynamic systems, such that they are more efficient in the use of resources and adapt appropriately over the life-cycle to ensure sustainability. This theme will also include aspects of machine learning and distributed decision making by CPS. Human machine interfaces will also be a significant consideration in this theme. Networked ICT has been a feature of supply chains for many years now; however, the current trend in CPS is towards greater distributed autonomy. This theme focuses specifically on creating an agenda to improve M&S for this contemporary advancement; the resulting collaborative research, if successful, will enable wider adoption of highly intelligent networked systems.

 

What is a test case?

Within the workshop, we aim to identify and work up one or more “test cases”. Test cases act like exemplars that will serve as demonstrators for stretching the capabilities of CPS modelling tools and techniques. The role of test cases is to provide M&S developers with a means to evaluate their product against the state of the art and other products. The format of a test case may vary depending on the M&S research area: some may require an accompanying data set, whereas others may just be a description of the use case. The minimal requirement for a test case is a detailed enough description to provide an unambiguous specification of a cyber-physical system. Ideally a test case should contain specifications for three different competency levels to provide a form of benchmark for an M&S product

Agenda

The workshop consisted of 4 half-day sessions.
