Architectural Design Decisions For A Knowledge-Based Distributed Systems Manager
Joseph C. Pasquale · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1987
A major fundamental problem in decentralized resource control in distributed systems is that in general, no decision-making node knows with complete certainty the current global state of the system. We present an architecture for an Expert Manager which provides a framework for dealing with this problem. Expert system techniques are used to infer the global system state using whatever partial state information is at hand, along with mechanisms for reasoning. Decision-making is enhanced by taking into account the uncertainty of observations, and that concurrent decisions made by many Expert Managers may conflict.
