2단계 물류네트워크 시뮬레이터 개발 = Development of the Two-Stage Logistics Network Simulator

다국어 초록 (Multilingual Abstract)

One of the important components in designing logistics network is facility location problem. It is possible to solve the real world location problem using the mathematical model included in the package because of the growth of computer hardware technology. In this paper the package is developed to find the optimal network flows and the relevant transportation cost according to the location alternatives of distribution centers in the two stage logistics network. For the given logistics network there are two types of the distribution schema according to the service area constraint of demand points. The one is the minimum cost network flow problem that is solved by the network simplex method and another is the integer programming problem that is solved by the branch & bound method. And the package extracts the distance data that is needed in the optimal model from the geographical data of GIS. The optimal solution can be found using the package developed in this research and the result cab be displayed on GIS map. And also a numerical example is illustrated.
