Abstract: | A fuzzy clustering-based hybrid method for a multi-facility location problem is presented in this study. It is assumed that
capacity of each facility is unlimited. The method uses different approaches sequentially. Initially, customers are grouped
by spherical and elliptical fuzzy cluster analysis methods in respect to their geographical locations. Different numbers of
clusters are experimented. Then facilities are located at the proposed cluster centers. Finally each cluster is solved as
a single facility location problem. The center of gravity method, which optimizes transportation costs is employed to fine
tune the facility location. In order to compare logistical performance of the method, a real world data is gathered. Results
of existing and proposed locations are reported. |
