摘要
针对民用飞机维修间隔优化问题,考虑目前国内航空公司定量优化评估方法和模型不足的实际情况,对隐蔽功能故障安全影响类维修间隔的优化调整进行研究分析,提出一种基于风险约束函数的平均不可靠度和成本率函数优化检查和恢复间隔的模型,并采用线性规划求解工具进行求解。最后,通过实际案例分析研究,验证该模型的合理性和有效性。
Currently considering the lack of quantitative optimization methods and models of civil aircraft to assess maintenance intervals for domestic airlines, maintenance interval optimal adjustment of 'safety effect' categories of hidden failures is studied and analyzed. In this paper, an optimization model based on the mean fractional dead time with risk-constraint and a cost rate function(CRF) is proposed to assess inspection and restoration intervals, and the linear programming tools are used to solve it. Finally, through the actual case analysis of study, the rationality and effectiveness of the model are verifi ed.
