Abstract

The method of missile condition assessment is researched. Missile condition is classified into five types: excellent, good, middle, poor and fault. If one or more characteristic parameters are unqualified, the missile condition is directly judged to be fault. If all characteristic parameters are qualified, the missile is qualified. To the qualified missile, a model of missile condition assessment based on an improved evidence theory is developed and the condition degradation grading of missile could be obtained by synthesizing the condition of all analog monitoring parameters on the basis of assessing characteristic parameter conditions. In order to use evidence theory to deal with conflict assignments in the process of synthesizing characteristic parameters, evidence theory is improved by using subdividing global conflicts into local conflicts and assigning conflicts according to the weight of conflict elements on the basis of analyzing improved evidence theories at present. Finally, the experimental result validates the rationality of the improved method.
