Equipment Support Capability Grade Evaluation Model Based on Multilevel Fuzzy System

Equipment support capability is a permanent problem at equipment support realm. Grading the equipment support capability enables better equipment support scheme. This paper applies the theories and methods of fuzzy mathematics and comprehensive evaluation. Based on fuzzy inference, its perform evaluations that are both qualitative and quantitative and contain exact and inexact factors. The paper determines the indexes of equipment support capability grade according to maximum equipment support capability degree, and assigns their weight using Analytic Hierarchy Process (AHP), thus quantify the qualitative problems. The solution improves the technology and reliability of equipment support capability grade evaluation, and is strongly applicable.
