Analytical tools for robust strategic and tactical planning in maintenance logistics networks

包括飞机维护、维修和大修(MRO)行业在内的维护和维修服务在加拿大是一个不断增长的行业，过去几年通过创造就业机会和收入为经济做出了贡献。高系统可用性对于飞机、大型计算机和医疗设备等高级资本货物至关重要。由于备件的种类和价格较高，这类设备的客户越来越少地减少内部维护投资，并倾向于将系统维护的主要部件外包给外部服务提供商。维修物流网络是由备件供应商、维修服务商和设备使用者组成的多层次供应链。在设备复杂的情况下，这种供应链不同于制造价值链，原因是备件数量多、种类繁多、零星的部件故障率、不确定的维修时间、单个部件的高价格以及备件短缺在财务上的显著影响。日益激烈的全球竞争和不断缩小的利润率迫使这个资本密集型行业寻找新的决策工具，以提高服务质量和交货期。

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.
