The proposed research will investigate production planning and optimization problems in manufacturing and remanufacturing (MAR) systems concentrating on applications in aerospace and rail equipment maintenance, repair, overhaul (MRO), refurbishment, and reassembly. Major transportation equipment such as commercial aircraft, aero engines, railway cars, are routinely serviced through MRO and refurbishment to provide safe and economical transportation services to public, industries and businesses. Such practice has been in place for long time and regulated by transportation authorities for highest level of public safety. Due to increased public concerns on environment and societal strive for sustainability, product remanufacturing and material/component reuse are more emphasized for reducing emission in production and the use of energy and resources. Research in general remanufacturing systems optimization is active with abundant literature available. However, numerical and mathematical tools for production planning and optimizing MRO processes of aerospace and other transportation equipment are limited. In this proposed research, analytical and mathematical models and solution methodologies for aerospace and rail equipment MRO process optimization will be developed. The developed models will capture common features and in decision making processes in aerospace and rail equipment disassembly, MRO, reconditioning, refurbishment, and other related activities. Optimal solutions from solving the developed models will be thoroughly analyzed for practical applications as often that optimal model solutions may not necessarily be optimal for solving the actual MRO problems due to model approximations and uncertainties of parameter and data values. The results of the proposed research complement that in general remanufacturing system optimization and  provide scientific decision support tools for MRO practitioners. According to 2018 government report, "State of Canada's Aerospace Industry", GDP of MRO activities shares 32% of Canadian aerospace GDP and grew by over 25% in the period of 2012-17. Rail MRO in Canada is typically performed by Canadian railway operators or by small and medium enterprises (SME) on project basis. The scientific tools developed in this research aiming at actual applications are anticipated to make Canadian MRO industry more competitive in producing safe, economical and sustainable transportation equipment.

拟议的研究将调查制造和再制造（MAR）系统中的生产计划和优化问题，重点是在航空航天和铁路设备维护、修理、大修（MRO）、翻新和重组中的应用。主要的运输设备，如商用飞机、航空发动机、铁路车辆，定期通过MRO和翻新服务，为公众、工业和企业提供安全、经济的运输服务。这种做法已经存在了很长时间，并受到交通当局的最高公共安全监管。由于公众对环境和社会可持续发展的关注日益增加，产品再制造和材料/组件再利用越来越受到重视，以减少生产中的排放和能源和资源的使用。一般再制造系统优化的研究十分活跃，文献丰富。然而，用于生产计划和优化航空航天和其他运输设备MRO过程的数值和数学工具是有限的。在本研究中，将发展航空航天和铁路设备MRO过程优化的分析和数学模型以及解决方法。开发的模型将捕获航空航天和铁路设备拆卸、MRO、修复、翻新和其他相关活动的共同特征和决策过程。由于模型近似和参数和数据值的不确定性，求解已开发模型的最优解在实际应用中可能不一定是解决实际MRO问题的最优解，因此将对其进行深入分析。本文的研究结果是对一般再制造系统优化的补充，为MRO从业者提供科学的决策支持工具。根据2018年政府报告“加拿大航空航天工业状况”，MRO活动的GDP占加拿大航空航天GDP的32%，并在2012-17年期间增长了25%以上。加拿大的铁路MRO通常由加拿大铁路运营商或中小型企业（SME）在项目基础上进行。本研究针对实际应用开发的科学工具有望使加拿大MRO行业在生产安全、经济和可持续的运输设备方面更具竞争力。
