A Inventory-Location Model for Multi-Period Pharmaceutical Supply Chain Network Design

This paper addresses an inventory-location problem in pharmaceutical logistics field. For this purpose, a multi-objective mixed integer programming model proposed in order to design a pharmaceutical network considering social impacts. The first objective function aims to minimize total costs, the second objective function is optimized the social impact of network. In order to more similarity to real world, in this study disruptions in capacity of the facilities are considered. Then, the proposed multi-objective model converted to single-objective model using LP-metric method and solved by LINGO software. Finally, a sensitivity analysis is done in some parameters of the proposed mode and results are reported. results showed with increasing amount of demand the value of first objective function increased and increasing amount capacity of DCs the value of first objective function decrease
