Knowledge-based intelligent assembly planning system

In order to obtain more feasible and practical assembly process,a knowledge-based intelligent assembly planning was presented.After analyzing the characteristics of the assembly process of connectors,typical knowledge base and standard knowledge base were set up for assembly sequence planning.There were three ways to generate assembly sequences:(1) by retrieving the typical match,(2) by retrieving the standard match,and(3) by sequence planning using directed-connector.In addition,to minimize product assembly period and to improve the flexibility and reliability of assembly system,a multi-agent based approach for cooperative assembly task planning was presented,which considered factors such as the assembly processing time and the time needed for the manipulators to change tools.
