Locating semantic error sources in a multi-agent system

摘要

A method and apparatus for automatically locating sources of semantic error in a multi-agent (ASB0/SB-ASBT/SB) system based on performance tests using setup connection tree information, and informing the appropriate agents so that they can avoid using error-producing resources in the future. The setup connection tree model is established based on patterns of agent actions for expressing the logical relationship between available resources (RSB0/SB-RSBY/SB) in the disjunctive normal form (d.n.f.). A table is used to record different sets of resources for use in a resource selection process. Thus, error-producing resources can be located by means of induction. A global database is also maintained for updating information on semantic errors in the system. A semantic error is a fault which can only be discovered when a performance discrepancy is detected by an application agent (ASB0/SB) during the operation of the application.
