In order to grasp the quality state of missile better, the missile quality evaluation based on fuzzy theory is analyzed. According to the test results of missile automatic test system, the quality assessment system of missile is classified by AHP, and the missile quality assessment framework is constructed. The classification rules of missile test data quality grade are designed. Through two-phase Fuzzy statistical method, the membership function model cabin of missile normalized test data belonging to various mass states is fitted, and the missile system and the whole missile quality are evaluated comprehensively. The evaluation results verify that the evaluation system is reasonable.
