Abstract: Aiming at the problems of high cost of sampling test, difficulty in evaluating the quality of batch gun-launched missiles, and ineffective use of manufacturing quality data in the manufacturing quality evaluation process of gun-launched missile, the manufacturing quality comprehensive evaluation method of gun-launched missile was studied. Firstly, the manufacturing quality comprehensive evaluation framework of gun-launched missile was put forward, and the manufacturing quality comprehensive evaluation process of gun-launched missile was standardized. The key characteristics determined based on failure mode analysis method were taken as evaluation indexes, and the manufacturing quality evaluation index system covering the purchasing, machining, assembling, and testing of the manufacturing process was constructed. The weight of each evaluation index was determined by using the analytic hierarchy process (AHP). Based on the production process capability index, the manufacturing quality evaluation calculation model was constructed, and the aggregation model of manufacturing quality evaluation was established based on weighted sum method and weighted geometric average method, so as to form a two-layer manufacturing quality evaluation model of gun-launched missile. The manufacturing quality evaluation of gun-launched missile was realized by making full use of the inspection data of key characteristics in the manufacturing process. Finally, taking a certain type of gun-launched missile as an example, the operability, feasibility, and effectiveness of the manufacturing quality comprehensive evaluation method were verified.
