Maintainability Prediction Method Based on Analytic Hierarchy Process

Through analyzing the existing methods of maintainability prediction and considering the requirement of weaponry maintainability, a unit-contrastive prediction method based on analytic hierarchy process (AHP) is presented. This method can meet the qualitative and quantitative requirements of weaponry without asking huge number of historical data and test data samples. With this method, the maintenance data of weaponry can be achieved by analyzing the profile of maintenance tasks of weaponry to determine reference unit and its maintenance data, and comparing the other units with the reference unit. This method is simple, applicable and cost-saving, especially is convenient for maintainability design. Application of this method to actual torpedo launch tube verifies its effectiveness and feasibility.
