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.

拟议的研究将研究制造和再制造（MAR）系统中的生产规划和优化问题，重点关注航空航天和铁路设备维护、维修、调查大修（MRO）、翻新和重新组装等主要运输设备的应用。铁路车辆定期通过 MRO 和翻新进行维护，为公众、工业和企业提供安全、经济的运输服务，这种做法已经实施了很长时间，并受到最高级别的交通运输部门的监管。由于公众对环境的关注日益增加以及社会对可持续发展的追求，产品再制造和材料/部件的再利用越来越受到重视，以减少生产中的排放，并且一般再制造系统优化的研究非常活跃。然而，用于航空航天和其他运输设备的生产规划和优化 MRO 流程的数值和数学工具是有限的，在本项研究中，航空航天和铁路设备 MRO 流程优化的分析和数学模型以及解决方法将受到限制。所开发的模型将捕捉航空航天和铁路设备拆卸、MRO、修复、翻新和其他相关活动的决策过程中的共同特征，并针对实际应用对解决所开发模型的最佳解决方案进行彻底分析。由于模型近似以及参数和数据值的不确定性，模型解决方案不一定是解决实际 MRO 问题的最佳方案。所提出的研究结果补充了一般再制造系统优化并提供了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%，并且在 2012-17 年期间增长了 25% 以上。由加拿大铁路运营商或中小企业（SME）以项目为基础，本研究中开发的针对实际应用的科学工具预计将使加拿大 MRO 行业在生产安全、经济和可持续运输方面更具竞争力。设备。
