Title: Decentralized execution system for production system
Inventor: ISHIDA TORU
IPC: G06F9/44
Filed: 1990-07-16
Abstract: PURPOSE:To solve the problems at a high speed without producing any interference between the rules by holding the knowledge of the formation at each agent and carrying out the rules asynchronously and in parallel with each other through each agent while securing the local synchronization with only the related agent based on the knowledge. CONSTITUTION:The knowledge of the formation prescribing such agents requiring the synchronization and the transmission of data is held at each agent 1. Then each agent 1 carries out the rules asynchronously and in parallel with each other while securing the local synchronization with only the related agent based on the knowledge. The rules are decentralized to plural agents 1 and carried out in parallel with each other. In this case, however, no synchronization is needed among all agents and only the local synchronization is required between the related agents 1. Therefore the wide-range synchronization control is not needed and the problems are solved at a high speed through the formation of such agents 1 that work asynchronously and in parallel with each other. As a result, the synchronizing overhead is reduced and the rules are carried out at a high speed.
