A key problem in designing multi-mode real-time systems is the generation of schedules to reduce the complexities of transforming the model semantics to code. Moreover, distributed multi-mode applications are prone to suffer from delays incurred during mode changes. We therefore aim to generate communication schedules that have low average mode-change delay for multi-mode real-time distributed applications. In this paper, we use optimization constraints associated to timing requirements to generate state-based schedules for multi-mode communication systems, and illustrate the workflow for generating schedules from specifications through a real-time video monitoring case-study. Our experiments in the case-study demonstrate that schedules generated using the proposed method reduce the average mode-change delay in relation to a randomized algorithm and the well-known edf scheduling algorithm.
