| Abstract: | In the logistics system, the facility location problem, which can be used to determine the mode, the structure and the form of the whole logistics system, is a very important decision problem in the logistics network. So a lot of works have been done by many researchers, and consequently, a great deal of models and algorithms are presented. Facility location method, especially for the multi-facilities location problem is one of the hot topics at present. In this paper, firstly, some concepts and the researching advances of multifacilities location are presented. Furthermore, according to various decision criteria, the multi-facilities location problem is formulated. Finally, a genetic algorithm is designed for solving the proposed rough programming models and a numerical example is also given. |
