HAPBA - A Holonic Adaptive Plan-Based Architecture

摘要

This contribution reveals how the planning and coordination processes in Holonic Manufacturing Execution Systems entail the need of a centralized component, under the form of a staff holon. By using appropriate models (both monochrome and coloured Petri nets) and certain aspects of planning techniques in Artificial Intelligence, a PROSA based implementation is considered. In the obtained holonic scheme, named HAPBA, the solution of the manufacturing goals is attained by holons' cooperation, according to an enhanced form of the Contract Net Protocol, so that certain drawbacks that are possible to appear in a holonic approach are avoided. Theoretical and experimental arguments are supporting the proposed solution.
