Maintenance and repairing services including the aircraft maintenance, repair and overhaul (MRO) industry is a growing sector in Canada that has been contributing to the economy by creating jobs and revenue over the past few years. High system availability is essential for advanced capital goods such as aircraft, mainframe computers, and medical devices. Due to the high variety and price of spare parts, customers of such equipment are more and more reducing their in-house maintenance investment and prefer to outsource major parts of system upkeep to an external service provider. The Maintenance Logistics Network (MLN) is a multi-echelon supply chain composing of spare part suppliers, maintenance service providers, and equipment users. Such supply chains, in the context of complex equipment, differ from manufacturing value chains due to the large number and diversity of spare parts, extremely sporadic part failure rates, uncertain repair times, high prices of individual parts, and financially remarkable effect of spare part shortage. Increasing worldwide competition and shrinking profit margins are forcing this capital-intensive sector to find novel decision tools in order to improve the service quality and lead-time. While spare part inventory planning for in-house maintenance systems has been extensively investigated in the literature, less research has been devoted to link inventory policies with strategic and tactical plans in MLNs in the context of external service providers. This significant gap in the literature in addition to financial issues Canadian MRO industries have been recently facing attracted our attention to investigate this problem from a supply chain viewpoint. Nevertheless, the latter raises several challenging questions in terms of coordination among independent MLN stakeholders. The overall objective of this research program is hence to propose an advanced modelling and algorithmic framework for MLN strategic and tactical planning while incorporating service part inventory control policies as well as high level of uncertainty inherent in such value chains. Designing coordination mechanisms among stakeholders of these logistics networks is another key element of this research program. Our methodology mainly relies on stochastic programming, decomposition algorithms, meta heuristics, supply chain coordination contracts, discrete-event simulation, and approximation algorithms for performance evaluation of multi-echelon inventory systems. By providing robust decision support tools, this multidisciplinary research program is expected to assist Canadian service/repair sector remain economically sustainable while maximising customer service level.

维护和维修服务在内，包括飞机维护，维修和大修（MRO）行业是加拿大不断增长的行业，在过去几年中一直在创造就业机会和收入来为经济做出贡献。高系统可用性对于飞机，大型机和医疗设备等高级资本货物至关重要。由于备件的种类繁多和价格，此类设备的客户越来越多地减少其内部维护投资，并且更喜欢将系统保养的主要部分外包给外部服务提供商。维护物流网络（MLN）是备用零件供应商，维护服务提供商和设备用户的多回波供应链。在复杂设备的背景下，这种供应链不同于制造价值链，由于备件的数量和多样性，极度零星的零件故障率，不确定的维修时间，个人零件的高价格以及备用零件的财务上的显着影响短缺。不断提高的全球竞争和利润率缩小，迫使这个资本密集型部门找到新颖的决策工具，以提高服务质量和交付时间。 尽管在文献中已经对内部维护系统的备件库存规划进行了广泛的研究，但在外部服务提供商的背景下，较少的研究将库存政策与MLN中的战略和战术计划联系起来。除了金融问题外，加拿大MRO行业除了最近面临的文献外，这一重大差距引起了我们的注意，从供应链的角度来研究这个问题。然而，后者在独立的MLN利益相关者之间的协调方面提出了一些具有挑战性的问题。因此，该研究计划的总体目标是为MLN的战略和战术计划提出一个先进的建模和算法框架，同时纳入服务部分库存控制政策以及此类价值链中固有的高度不确定性。这些物流网络的利益相关者之间的协调机制是该研究计划的另一个关键要素。我们的方法主要依赖于随机编程，分解算法，元启发式方法，供应链协调合同，离散事件模拟和近似算法，用于对多ECHELON库存系统进行性能评估。 通过提供强大的决策支持工具，该多学科研究计划有望帮助加拿大服务/维修部门在经济上保持可持续性，同时最大程度地提高客户服务水平。
