【 摘 要 】

To solve the problem that the FMECA of missiles is difficult to be quantified and the indicators are diverse, a method to describe the fault criticality of missiles based on multi-level fuzzy comprehensive evaluation theory is proposed. In this paper, a television guidance missile is taken as an example, factor sets, evaluation sets, weight sets, comprehensive evaluation based on multi-level fuzzy theory of missile is established. A comprehensive evaluation indicator Cx is proposed to quantitatively describe the fault criticality of missiles. This method is exact and effective to solve the problem of indicator diversity, and can provide basis for reliability research of missiles.
