一种协同诊断的任务协作规划方法

在多诊断资源协同诊断领域,由于装备复杂性和诊断资源异构性,诊断任务分配应具有自适应性.提出了一种动静态集成的协同诊断任务分配方法.在静态任务分配中,以装备的定性模型和模糊关系矩阵建立了诊断任务关系模型,通过改进D算法实现诊断路径规划,运用多约束整数规划进行资源配置;在动态诊断任务分配方法中,引入了基于效用和协商的扩展合同网方法.最后,通过工程装备的诊断事例验证了分配方法的有效性,并通过结论总结和延伸了该方法.

A task allocation method for collaborative diagnosis

In the multi-resources collaborative diagnosis,because of the complexity of equipment and the heterogeneous nature of diagnosis resources,diagnosis task allocation should have adaptability.This requirement can be realized by a dynamic-static integrated allocation method.In the static allocation method,diagnosis task relation model is established by means of the qualitative model of equipment and fuzzy relation matrix,diagnosis path planning is realized by improving D-algorithm,and multi-constraints integer planning is used for resource allocation;in the dynamic allocation method,an extended contract net method is introduced,which is based on utility and negotiation.The validity of this method is proven by means of a case of an engineering equipment diagnosis.
