飞机预防性维修任务间隔优化模型与方法研究

飞机维护规程中规定了飞机部队级维护涉及的所有预防性维修任务，在飞机服役初期，维修任务的制定通常偏保守，随着飞机使用和维护经验的积累，维修任务间隔优化的需求越来越明显。以服役数据为分析对象，以系统可靠度为衡量标准，构建预防性维修任务间隔优化分析方法，形成可实现的数学模型；以某维修任务为案例，对其服役数据进行分析，并给出维修间隔优化的建议。结果表明：该方法和模型正确可行，可作为军用飞机维修任务间隔优化分析的参考。

Research of Preventive Maintenance Task Interval Optimization Model and Method of Aircraft

Aircraft maintenance order is the main basis for military aircraft maintenance work. The orders specify all preventive maintenance tasks involved in aircraft basic level maintenance. With the accumulation of aircraft use and maintenance experience, the demand for optimization of maintenance task interval is becoming more and more obvious. Taking the service data as the analysis object and the system reliability as the measurement standard, this paper constructs the mathematical model of preventive maintenance task interval optimization analysis. Taking a maintenance task as an example, this paper analyzes its service data, and gives suggestions on maintenance interval optimization. The example has proved the feasibility of the mathematical model which can be used as a reference for military aircraft maintenance task interval optimization analysis.
