There are numerous spare parts in the carrier-borne aircraft landing guidance equipment system,and the effect of traditional unit-level spare part support is limited,so it is impossible to evaluate the entire spare part system efficiently and comprehensively.In regard to these problems,the k/N(G) voting relationship is introduced to decompose the complex system into a series-parallel structure equivalently.The prediction model of the spare part support probability,use availability,the utilization rate and other key indicators under different life distribution types of the spare part is proposed.In regard to the deficiency that the indicator statistics can only be obtained after finishing the task,the analytical calculation method is used to pre-assess of the spare part plan to improve the effect of spare part support,and the calculation method of each index on the system level is further given.Through an example analysis,it is proved that the accuracy and comprehensive evaluation ability of the spare part support plan on the system level are improved compared with that of the traditional method,and the simulation results are in line with the actual situation.
