Outline of Final Research Achievements

In this study, we note that an operating situation of a system determines what functions of the system run. More concretely, an operating situation determines what data the system requires and how frequently it requires them. Each operating mode is specified by a set of communication signals which are active under the corresponding operating mode. A task of system designers is to schedule all messages of communication signals so that the messages are sent by their own deadline. We proposed a design methodology which optimally determined a message schedule for each operating mode so that it could avoid wasting networking resources.

Academic Significance and Societal Importance of the Research Achievements

TDMA(Time Division Multiple Access)法に基づくリアリタイムネットワークシステムの設計において、メッセージスケジューリングとネットワークトポロジを自動合成することにより、設計期間の短期化、設計コストの削減、及び部材コストの削減が実現できるようになった。より幅広い製品群においてリアルタイムネットワークの適用が容易になった。
