摘要:
针对民用飞机维修任务多、费用高、维修间隔差别大的特点,基于成组维修策略,提出了民用飞机成组维修方案的优化模型。将民用飞机维修费用分为由于集中开展预防性维修而造成的停机损失费用和与部件本身相关的费用,包括由于落实预防性维修而产生的耗材、人工等费用,因采取非计划维修而产生的排除故障相关费用,由于发生故障而造成的损失费用。研究了成组维修方案对民用飞机平均维修费用率及日利用率的影响。以基本定检间隔和各部件维修任务间隔为优化变量、民用飞机日利用率和可靠度为约束、维修费用最小化为目标函数,建立了民用飞机成组维修方案的优化模型。以CRJ200空调系统为例,制定系统成组维修方案,得到民用飞机的基本定检间隔并调整各部件的维修任务间隔,达到全局最优,证实了该成组维修方案优化模型的有效性。
Abstract:
Aiming at the characteristics of civil aircraft maintenance of many tasks,high costs and vast differences of maintenance intervals,an optimization model of group maintenance scheme for civil aircrafts is proposed based on group maintenance policy.The maintenance cost of civil aircraft is divided into shuting down cost for preventive maintenance,cost for components including consumptive material cost and labor cost for preventive maintenance,trouble shooting cost for unscheduled maintenance and loss for failure.The influences of the group maintenance scheme on daily utilization ratio and average maintenance cost efficiency of civil aircraft are researched.An optimization model of group maintenance scheme for civil aircrafts is established with a basic regular inspection interval and maintenance task intervals as optimization variables,the daily utilization ratio and reliability of civil aircrafts as constraints and the minimality of the maintenance cost as the objective function.A group maintenance scheme is made for CRJ200 conditioner system,a basic regular inspection interval for the civil aircraft is obtained and the maintenance task intervals for components are adjusted to achieve global optimum,which affirms the availability of the optimization model of group maintenances scheme.
