摘　　要：建立冷气系统的维修检测模型,将系统的状态按照维修方式分为正常、异常和故障,通过对冷气系统的可靠性进行分析,检测时间是任意的随机变量;以飞机的最大可用度和冷气系统的最小预防性维修费用为目标函数,以系统故障风险为约束条件,采用量子遗传算法,求得冷气系统最佳检测间隔期。Pneumatic system maintenance inspection model was established,the state of the system into maintenance mode in accordance with normal,abnormal and failure,By analyzing the reliability of pneumatic system,the detection time is arbitrary random variable.The maximum availability of aircraft and pneumatic system and the minimum of preventive maintenance cost as objective function,the risk of system failure as the constraints,using genetic algorithm,the best pneumatic system inspection interval was obtained.
