摘　　要：诊断任务分配是远程协同诊断的一个内容和难点;在经典合同网分配方法基础上,提出的扩展合同网分配方法依据诊断任务的相似范例推理和阈值规则确定投标诊断资源联盟,以满意效用并经过协商来签订和执行合同.该效用由多约束模糊系数法确定;给出了扩展合同网分配方法的算法描述和UML执行流程,通过一个FMS诊断任务分配过程验证了该方法是一个动态、有效的智能诊断任务分配方法;在结论中指出了进一步研究点。diagnostic task allocation is a content and difficulty of remote collaborate diagnosis. Based on classical contract net allocating method, an extended contract net allocating method are put forwarded, it can, firstly, ascertain diagnostic resource bidding alliance by diagnostic task similar case reasoning and threshold rule, then subscribe and implement task contract after negotiation depending on satisfying utility, this utility is confirmed by multi- restriction fuzzy coefficient method. Algorithmic description and UML flow of execution are also presented. In the end, ECN allocating method is validated that it＇s a dynamic and effective intelligent diagnostic task allocating method according an FMS diagnostic task allocating process.
