Fuzzy decision-making for selection of mobile base station location

The selection of base station location is one of the most important decision issues for mobile operators. We propose in this paper a new multiple criteria decision-making method in order to solve the location of base station problem under fuzzy environment. In the proposed method, the ratings of each alternative and the weight of each criterion are described by linguistic variables which can be expressed by triangular fuzzy numbers. The final evaluation value of each base station (BS) location is also expressed by a triangular fuzzy number. By calculating the difference of final evaluation value between each pair of BS locations, a fuzzy preference relation matrix is constructed to represent the intensity of the preferences of one location over another. And then, a stepwise ranking procedure is proposed to determine the ranking order of all candidate locations. Finally, we have realized simulation in Matlab, and solved different examples of decision-making for selecting the base station location.
