Course on Modelling and Analysis of Component-based Systems

A course called “Modelling and Analysis of Component-based Systems” (MOANA-CBS) is being developed in collaboration with Thales as a part of the DYNAMICS project. The course addresses the challenge of overseeing the explosion of possible interactions between asynchronously communicating components in component-based systems. Some of these interactions may be undesirable and leave systems prone to deadlock, livelock, race conditions, and buffer overflows, reducing software quality. The course participants in the course learn how to mitigate this problem by modelling the behavior of components and interfaces using Petri Nets, a well-known formalism suitable for describing asynchronously communicating systems. Theory is linked to practice through demonstrations of relevant examples using the ComMA tool. Using properties and analysis methods for Petri Nets, they learn how to identify patterns in component and interface design that may cause the aforementioned problems, as well as design guidelines for how to avoid them. The course is taught using a combination of lectures, assignments, demonstrations, discussions, and reflection.

We piloted parts of the course at Van der Valk Hotel in Arnhem on October 7 and 8, attended by 12 software architects from Thales and Luminis. The course was positioned as a part of their Accelerate program, which aims to accelerate young architects from the two companies into a more senior role. We felt that the delivery of the course went well and evaluations from the participants suggests it was well-received. The evaluation of this pilot also highlighted some further points for improvement that will be considered going forward.
