碩士 === 國立臺北科技大學 === 工業工程與管理研究所 === 98 === Hierarchical location problems have been widely investigated and studied in the past two decades. Models associated with this problem can be applied in real life and can help decision makers to make feasible and economical decisions. The problem of locating medical facilities is one of the most popular topics in hierarchical location problems. This paper will firstly concentrate on the overview of the past research and build up a complete comparison of these papers. We build up a website which is about hierarchical facility location problem. We also design a new two-level flow-based hierarchical facility location model. The goal of the proposed model is to minimize the summation of the weighted distance which is produced by the system. We consider some factors like the capacity, the budget and the proportion of referral in the proposed model which have been considered by previous papers. This model is composed of demand points, clinics and hospitals and we hope this model can be applied to select the location of the medical facility in reality. We use CPLEX to compute the best solution for the experiment.
