碩士 === 國立交通大學 === 工業工程與管理系所 === 93 === Locating fixed facilities throughout the logistics network is an important decision problem that gives form, structure and shape to the entire logistics system. Location decisions involve determining the number, locations and capacities of the supply centers to be used. The paper presents a new procedure to solve the minimax problem or p-center problem. The system design according to the solutions of the p-center problem is an alternative under selection. We compute the eight parameters for each alternative such as the minimax distance, average and coefficient of variation of transportation distance per unit of goods, average and coefficient of variation of transportation distance per site, the total fixed setup cost for the centers, and the two total costs that depend on the capacity of the centers: variable construction cost and transportation cost. All the possible alternatives with the eight parameters are evaluated. Several Pareto-efficient alternatives would be selected.
