摘要: 与传统的制造业调度问题相比,一些复杂的特点使得航空维修企业调度问题更加难以处理,如:拆分-修理-组装的三级结构、物料匹配需求以及不确定工艺路线和工时。在对航空维修企业调度问题详细分析的基础上,本文建立以最小化期望权重延误时间为目标的混合整数线性规划模型,因为该问题是NP-hard问题,通过使用传统的优化方法很难求得最优解,本文提出基于多精度仿真模型的MO2TOS算法对该问题求解,其中高精度模型包含随机参数,直接运行比较耗时,而低精度模型属于确定性模型,更适合用于MO2TOS算法的序转换阶段。最后,通过基于实际背景的算例验证了模型的可行性并对比分析了MO2TOS和其他相似算法的特点。

Abstract: Compared with the traditional manufacturing system, several key characteristics make MRO(maintenance, repair and overhaul) scheduling problem different and difficult to handle, such as Disassembly-Repair-Assembly three-level structure, Material matching requirements, Stochastic routings and Variable processing times. On the basis of a detailed analysis of the MRO scheduling problem, a mixed integer linear programming model to minimize the expected total weighted tardiness is presented. Since this problem is NP-hard, a practical way of achieving good solutions is to develop effective simulation optimization algorithms. Multi-fidelity models, including one which is stochastic and time-consuming, are developed based on MO2TOS(multi-fidelity oftimization with ordinal transformation and optimal sampling) framework to solve this problem. Instead of directly running the high-fidelity model, a deterministic low-fidelity model is provided for OT(ordinal transformation) stage. Finally, the characteristics of different algorithms are analyzed by the numerical examples based on the practical background.

Key words: aviation maintenance, scheduling, stochastic routings, variable processing times, multi-fidelity models
