Abstract: To solve the problem of modeling equipment performance degradation and prediction system， a hierarchical model based on multi-Agent system was proposed. In this model， the framework of the system was designed. According to the equipment functional structure， the performance degradation and prediction Agents for each hierarchy were divided and the concrete functions for each Agent were also defined. This system model provided a guidance template to implement equipment performance degradation and prediction system.

Key words: equipment performance degradation assessment and prediction, multi-Agent system, functional hierarchical model
