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

该提案涉及设计一个决策工具，用于管理Jazz Air LP的维护业务和备件库存，最著名的是Jazz Air Jazz。Jazz是加拿大地区航空运输的领头羊，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个主要地区基地运营800多个航班。由于可靠性和服务要求较高，维护活动至关重要。在达到若干飞行小时后，将强制进行检查。在检测到故障时进行维修，或采取预防措施避免故障。所有这些活动都需要对资源和设施进行良好的规划和协调。备品备件被保留，以便快速执行维护活动，以减少维护停机时间并增加飞机可用性，从而确保更大的客户满意度。然而，这些备件价格昂贵，保持大量库存的成本可能非常高。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优库存水平，并拥有一个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.
