Abstract

The location–routing problem (LRP) deals with simultaneously selecting (locating) one or more facilities from a set of potential facilities (locations), and assigning customers to the selected facilities. Since LRP and inventory decisions are inter-related, integrating them can lead to a more efficient supply chain. Therefore, to improve the operation of the supply chain process, this paper presents a model that integrates inventory control, as a tactical decision, with the LRP. The presented model considers the multi-product network under the fixed order interval inventory policy with stochastic demands for products. Moreover, third-party logistics offers excess space for selected warehouses if needed. This paper also presents a solution approach based on simulated annealing that solves problems with the size of 40 products and 350 customers in reasonable run time.
