Embodiment Construction

[0046] The following is a detailed description of preferred embodiments of the invention including descriptions of the best mode currently contemplated by the inventors for the invention. It will be apparent to those skilled in the art that specific features of the invention may be replaced by known equivalents thereof, even if not expressly stated, and that the scope of the invention is intended to include such equivalents, as appropriate.

[0047] Referring to Fig. 1 of the accompanying drawings, a mediator-based multi-agent system (MAS) architecture according to an embodiment of the present invention is schematically shown. In FIG. 1 , an architecture 1 includes a plurality of constituent bodies 2 a , 2 b , 3 and an intermediary body 4 arranged to interconnect each constituent body 2 a , 2 b , 3 . The intermediary agent 4 is also configured to provide input to the management system 5 so that each constituent agent can subscribe to the intermediary service of the intermediar...

Abstract

A method for recovering the cooperation state among multiple constituent agents in a multi-agent system architecture, the method comprising: processing cooperation information forwarded by an intermediary agent for each constituent agent; maintaining Cooperative processing state information records derived from said cooperation information of ; and in the event that a device implementing cooperation encounters an event that causes one or more constituent subjects to lose their cooperation status, use one or more The collaboration processes state information records to restore the collaboration state.

Description

technical field [0001] The present invention relates to a mediator-based recovery mechanism for multi-agent systems. More specifically, but not exclusively, the present invention relates to recovery mechanisms in which multiple software agents interact online in time-critical applications that require each agent to be aware of what other agents have achieved latest status. Background technique [0002] Fault-tolerant multi-agent systems are already known in the art. For example, Staffan Hagg, "ASentinel Approach to Fault Handling in Multi-Agent Systems", in Proceedings of the Second Australian Workshop on Distributed Al, inconjunction with Fourth Pacific Rim International Conference on Artificial Intelligence (PRICAI'96), Clairns, Australia, 1996 presented A method of fault handling in a multi-agent system in which a "Sentinel" agent monitors messages exchanged between application agents to detect any malicious or faulty agents. Implementing Sentinel agent systems makes m...
