ISHM-Oriented Time Decision-Making for Condition-Based Maintenance of Multistate Systems

In this paper, an integrated system health management oriented condition monitoring and maintenance decision-making model is proposed, which uses intelligent mobile agents to achieve real-time monitoring and to realize life cycle maintenance decision-making for multistate systems (MSSs). The model is applied to an aircraft engine system numerical example, the results of which illustrate that the proposed system and model have the ability to provide efficient and accurate engine system maintenance decision-making information and provide detailed health condition information. The feasibility of the proposed system and model is demonstrated and MSS frequent maintenance decisions are recorded and revealed.
