Optimization of maintenance operations and spare parts inventory for an heterogeneous fleet of aircrafts.

本提案涉及Jazz Air LP（最著名的是Air Canada Jazz）的维护操作和备件库存管理决策工具的设计。 Jazz是加拿大区域航空运输的领导者，拥有131架飞机，服务于加拿大和美国的85个目的地，每天从6个主要区域基地运营800多个航班。由于高可靠性和服务要求，维护活动至关重要。 在飞行小时数达到后，必须进行检查。 当检测到故障或预防性地避免故障时，进行维修。 所有这些活动都需要对资源和设施进行出色的规划和协调。 我们保留备件以快速执行维护活动，从而减少维护停机时间并提高飞机可用性，从而确保更高的客户满意度。 然而，这些备件是昂贵的，并且保持大量可能非常昂贵。 因此，必须使用先进的数学模型来确定每个基地要保持的最佳库存水平，并具有主动调度系统来协调维护活动。

This proposal deals with the design of a decision-making tool for the management of maintenance operations and spare parts inventories for Jazz Air LP best known as Air Canada Jazz. Jazz is the leader of the regional air transportation in Canada with 131 aircrafts, serves 85 destinations in Canada and the United-States and operates more than 800 daily flights from 6 main regional bases. Due to the high reliability and service requirements, maintenance activities are critical. Checks are mandated after a number of flying hours are reached. Repairs take place when a failure is detected or preventively to avoid failure. All these activities require excellent planning and coordination of resources and facilities. Spare parts are kept to quickly perform maintenance activities in order to reduce maintenance downtime and increase aircraft availability which ensures greater customer satisfaction. However, these spare parts are expensive and keeping large quantities can be very costly. Therefore, advanced mathematical models must be used to determine the optimal inventory levels to be kept by each base and have a pro-active scheduling system to coordinate the maintenance activities.
