摘　　要：对于复杂分布式故障诊断的特点,集成多种智能方法求解是一种有效的途径。但如何确定这些诊断方法的相对诊断能力是基于多代理技术的故障诊断系统中的一个关键问题。文章基于问题求解的粒度理论,在对设备故障域进行分解的基础上,提出了基于多代理技术的三层评估模型,不仅能对诊断专家的诊断能力进行评估,而且也能对多诊断专家的协调诊断能力进行评估。该方法简化了问题求解的难度,提高了多专家评价的精度。可广泛应用于多诊断专家代理联盟的创建和诊断结论的融合中。For complicated distributed fault diagnosis, integrated multi-intelligence solution-finding is an efficiency way. However, how to determine the relative diagnosis capability of those diagnosis methods is a key problem in fault diagnosis system, which is based on multi - agent technology. On the foundation of solution finding - based granularity theory and decomposing the equipment malfunction, this paper proposes a threelayered evaluation model that is based on multi-agent technology. It not only can evaluate the expert＇s diagnosis ability, but also the coordinate diagnosis ability of many diagnosis expert. This method eases the difficulty of solution-finding, and improves the precision of many expert＇s diagnosis. It can be used wildly in the combination of multi-expert agent federation＇s building and diagnosis conclusion.
