A new multiobjective modeling in distribution center location problem

چکیده مقاله

ABSTRACT
As has been mentioned in the literature, distribution centers location problem (DCLP) is a multiobjective
problem. Cost (or distance) minimization is the primary objective in this area. While significance of each relation
between a distribution center (DC) and a customer/retailer is different, it has not been considered seriously. By
adapting available facility and new facility concepts of the multifacility location problem with costumer/retailer
and a DC respectively, a utility function as the second objective based on the importance has been used. These
importances are in decision maker (DM) s’ mind which should be quantified to be of use for modeling purpose.
We proposed a method for the uncapacitated single stage facility location problem (UFSLP) in which a fuzzy
AHP method is used to achieving these importances. So we presented a multiobjective model in which
minimizing total cost is first objective and maximizing the utility function is the second one. LP-metric method is
used to solve our multiobjective model. Finally, a numerical example is expressed for illustration of the proposed
method.
