Abstract:According to the situation echelon usage control of aircraft lacks of evaluation indexes, this paper constructed a comprehensive evaluation index. Based on the existing research results, analyzed the purpose of echelon usage control, established five evaluation indexes (including aircraft combat readiness, echelon usage situation of residual life, fatigue damage, corrosion damage and execution progress of plan) and the mathematical model, determined every index weight by using analytic hierarchy process (AHP). The results show that the evaluation indexes can be used to quantitatively evaluate the aircraft echelon usage control condition, and also plays an important role in instructing the aircraft echelon usage control in air unit.
