碩士 === 元智大學 === 工業工程與管理學系 === 96 === The thesis explores a decision problem on selecting the best alternative among various maintenance schedules for four types of military equipments that are currently in use. The problem under study involves two multi-criteria decision making issues: Selecting the best schedule (1) that maintains and repairs simultaneously four different types of equipments and (2) that maximizes the productivity of the maintenance working centers within a whole year. The research results will provide a valuable reference for the relevant management to make good decisions. The problem solving approach to the first issue consists of fives phases: (1) Determine the objectives that the management is concerned with; (2) Construct multi-objective linear integer models for the problem; (3) Collect relevant data from the working centers; (4) Find a set of Pareto optimal solutions by employing LINGO optimizer to the models; (5) Provide the best alternatives to the management based on their concerns. A simulated annealing algorithm is developed to solve the second issue; i.e., to find the maximum maintenance capability of the working centers within one year. The alternatives under consideration have a makespan between 360 and 365 days. Similar to the first issue, a limited number of alternatives, as well as the analysis of benefits and losses, are provided to help the management make a good decision. Additionally, a sensitivity analysis is performed on a particular and important working center in the situation where one additional unit of such center is constructed. A detailed discussion and decision making based on the sensitivity numerical results are included in the thesis.
