Application of ranking function to solve fuzzy location-routing problem with L-R fuzzy numbers

Abstract

This paper addresses the Fuzzy Location-Routing problem (FLRP), raised by distribution networks involving depot locations, customer assignment and routing decisions in order to minimizing the total costs. Also this paper develops a simple approach to solve FLRP with traveling times along particular roads being L-R fuzzy numbers. The idea is based on the fuzzy linear programming (FLP) and fuzzy number ranking method.
