碩士 === 國立中央大學 === 土木工程研究所 === 94 === In this research, on the basis of the carriers’ perspective, we develop a long-term and a middle-term aircraft maintenance scheduling models, in accordance with the related constraints in actual operations. Although some past research has used zero-one integer programming methods to develop related models, they only considered their own fleet with the objective of minimum aircraft maintenance cost, neglecting the maintenance of their customer’s aircraft. In this research, we consider both the objectives of the minimum aircraft maintenance cost of the carrier’s own fleet and the maximum maintenance revenue of its customers’ aircraft to develop a long-term model that is formulated as a multiple objective zero-one integer program. Besides, since the middle-term model must be developed after the season’s flight timetables have been determined, we develop the middle-term model base on season’s flight timetable and long-term model’s results. We apply mathematical programming techniques to construct a long-term and a middle-term aircraft maintenance scheduling models. These two models are formulated as zero-one integer problems. Its worth to note that the long-term model of aircraft maintenance schedules has two objective functions, therefore, we apply the weighting method to deal with the multiple-objective model. In a practical application with our proposed model, we interview with aircraft maintenance planners to gather data of realistic maintenance schedules. In the following, we have developed the programming code to calculate the results of the two models. We perform a case study using the real operating data from a major aircraft maintenance hangar in Taiwan. All analyses of results are performed with the mathematical programming solver, CPLEX. At last, some conclusions and suggestions are proposed. These two models are expected to be useful planning tools for international aircraft maintenance hangar to decide on their optimal aircraft maintenance plans in their operations.
