An autonomous decentralized system architecture for distributed information and control systems

The recent movement to information and control applications, such as customer driven production, has resulted in new requirements for such systems, that are compatible with the flexibility expanded or modified system for reflecting a variety of customer requests and real timeness guaranteed operations. The paper proposes a system model and software architecture which enables flexible and real time systems and is based on the autonomous decentralized system concept, which is tolerant of heterogeneous subsystems in a system. To realize this model, a software architecture implemented using a new technology is proposed. This technology is a system filtering mechanism that manages cooperation between subsystems composed of multiple nodes, and which has different kinds of quality of operation. The proposed system model and software architecture has been applied to many industrial production systems, and their effectiveness has been verified.
