摘要:Aimingat the lack of foundation for the maintenance strategy of equipment-intensive enterprises. This paper is based on the analytic hierarchy process to obtain the importance of equipment in the system, which qualify the equipment operation data and expert experience data by layer. Firstly, the system is modeled according to correlation, and then the consistency evaluation matrix is constructed. Finally, the reliability ratio can be used to simplify the system model. For the equipment-intensive systems such asa metro station system, the experimental data can match well with the empirical data. This method is able to achieve reliability-centered, which can also make the system a promotion efficiency of maintenance decisions and a reduction in the cost of operation and maintenance.
