AHP based wartime armored equipment chassis failure maintainability probability calculation

On the basis of the peacetime armored equipment chassis failure maintenance workload statistic data, it is gained that the peacetime armored equipment chassis failure maintainability probability function accords with exponential distribution according to the statistics method. With analyzing the maintainability probability parameter influence factors, the wartime and the peacetime mean repair time hierarchy is founded, applying the AHP with the maintainability probability parameter influence factors as the rule layer, and the combination weights are calculated so that the wartime chassis failure maintainability probability function is got. The relative conclusions are given, and a new method to solve the wartime equipment maintainability orderliness without the wartime statistic data is provided.
