“…MAST implementation is open source under GPL license and it has been successfully integrated in other modelbased development tools as part of a MDE (Model Driven Engineering) methodology [30]. The second version of the metamodel, MAST 2 [31], adds new modelling elements and scheduling policies, such as ARINC 653 compliant time partitioning.…”

Modern industrial cyberphisical systems exhibit increasingly complex execution patterns like multipath endto-end flows, that force the real-time community to extend the schedulability analysis methods to include these patterns. Only then it is possible to ensure that applications meet their deadlines even in the worstcase scenario. As a driving motivation, we present a real industrial application with safety requirements, that needs to be re-factored in order to leverage the features of new execution paradigms such as time partitioning. In this context we develop a new response-time analysis technique that provides the capacity of obtaining the worst-case response time of multipath flows in time-partitioned hierarchical schedulers and also in general fixed-priority (FP) real-time systems. We show that the results obtained with the new analysis reduce the pessimism of the currently used holistic analysis approach. INDEX TERMS Schedulability analysis, time partitioning, hierarchical scheduling, distributed systems, safety, industrial application.
