RESEARCH ON TASK ALLOCATION OF COOPERATIVE FAULT DIAGNOSIS BASED ON EXTENDED CONTRACT NET
摘要
Abstract
Task allocation is an important part of collaborative fault diagnosis technology,whether the task allocation mechanism is good or not directly affects the efficiency and accuracy of the diagnosis.For existing contract net protocol,the low allocation efficiency and the huge task load could easily lead to the problem such as over-busy single node.Thus,a task allocation mechanism of collaborative fault diagnosis is proposed based on extended contract net.Firstly,using Hash algorithm to establish allocated knowledge base which links sub fault tasks with the corresponding distribution path,providing expert distribution experiences for task allocation.Then,combining the Dijkstra algorithm with the contract net protocol,the task allocation node of high "cost-effective" is chosen by balancing the capability of fault diagnosis and the path weight.Simulation results show that the extended contract net task allocation algorithm reduces the traffic and improve the allocation efficiency.关键词
