The main aim of this research is to develop a decision support system for determining warehouse location. An anticipated model is constructed with fuzzy extension of the Analytic Hierarchy Process (FAHP) and fuzzy extension of the Technique for Order Preference by Similarity to Ideal Solution (FTOPSIS) methods. In this article 16sub-criteria divided in 5 main groups are taken for location decision model collected from literatures review and practical investigations in the distribution arena in Bangladesh. The weights of the sector and sub-sector are estimated by FAHP method and using FTOPSIS, eligible locations are ranked according to the results. Finally, an empirical study for warehouse location-allocation problem of the retail chain of Rahimafrooz Superstore Ltd. (RSL) named Agora in Bangladesh is presented to visualize the methodologies and effectiveness of the model proposed by this paper.
