摘要: 提出了民用航空发动机空中停车率与维修成本控制的优化决策方法.以空中停车损失期望作为间接营运成本指标,以维修成本与间接营运成本之和最小为优化目标,建立了确定最优空中停车率的数学规划方法,并给出了空中停车率与维修成本优化控制的简化方法.本文所提供的优化决策方法对航空公司进行在翼航空发动机的任务可靠性水平与维修费用控制决策有参考价值.

Abstract: Optimization methods to control the in-flight shutdown rate and the maintenance cost of civil aero-engines are presented in this paper. The mathematical planing approach to determine the optimal in-flight shutdown rate of an aero-engine is developed, in which the lost expectation of in-flight shutdown is taken as the index of indirect operating cost and the minimum sum of maintenance cost and indirect operating cost is treated as the optimization objective. On the basis of the mathematical planing, a simple optimization method to control in-flight shutdown rate and maintenance cost is provided. The methodologies have reference value for an airline company to make decisions to control task reliability level and maintenance cost of an aero-engine in the wing.
