| 摘 要： | 基于现代排序理论的建模思想, 分析了飞机对发动机的需求特性和发动机使用维修的周转特点, 引入工作节的概念, 建立了基于视情维修策略的航空发动机调度模型, 提出了求解模型的改进在线LPT算法, 并以CF6型发动机的使用数据验证了本方法的有效性。发现排序规则是调度计划的重要影响因素, LPT规则与传统的FCFS规则相比, 发动机在翼时间长, 送修次数少, 保障率高, 租赁损失成本低。分析结果表明: LPT规则优于传统的FCFS规则, 基于视情维修策略的航空发动机调度模型有效、可行。

| Abstract: | Based on the modeling thought of modern scheduling theory,the requirement property for aeroengines and the turnover property of aeroengine maintenance were analyzed,the concept of work note was introduced,a scheduling model of aeroengines under condition-based maintenance strategy was established,an online longest processing time(LPT) rule algorithm was improved for solving the model,and the used data of CF6 aeroengines were studied.It is pointed that aimed at aeroengine,on-wing time is longer,maintenance time is lower,guarantee rate is higher,and rental loss cost is lower when LPT rule is compared with traditional first come first serve(FCFS) rule.Analysis result indicates that LPT rule is better than FCFS rule,and the model is feasible.3 tabs,2 figs,10 refs. |
