Abstract: This paper proposes a makespan and reliability-based approach, a static scheduling strategy for distributed real-time embedded systems that aims to optimise the makespan and the reliability of an application. This scheduling problem is NP-hard and we rely on a heuristic algorithm to obtain efficiently approximate solutions. Two contributions have to be outlined: first, a hierarchical cooperation between heuristics ensuring to treat alternatively the objectives; and second, an adaptation module allowing improving solution exploration by extending the search space. The results are a set of compromising solutions offering the designer the possibility to make choices in line with his (her) needs. The method was tested and experimental results are provided.
