| Outline of Final Research Achievements |
The research has developed a real-time distributed computing environment for cyber-physical systems, such as distributed embedded control systems, which utilize distributed sensor inputs. This environment consists of a distributed computing platform and a distributed computing software development environment. The former is based on a meshed distributed computing model and comprises a real-time operating system and distributed computing middleware, which maintain temporal data integrity. The latter includes a model transformation tool that supports application development.

| Academic Significance and Societal Importance of the Research Achievements |
本研究で開発した分散処理環境は、従来の逐次型分散処理モデルに代えてメッシュ型分散処理モデルを採用するとともに、論理時間やタイムスタンプを用いることでデータの時間的整合性を保証するとともに、入力から出力までの端点間応答時間の制約を満たす動作が可能である。これにより、分散された多数のセンサ情報を収集してリアルタイム制御を行う分散制御システム等のサイバーフィジカルシステムを容易に開発可能とした。
