Abstract:
In this research a joint location- inventory problem is analyzed. We assumed two kinds of inventories: fast-moving and slow-moving goods. These two kinds of goods can be observed in after sales service systems. In the real world fast moving goods are stocked in all dealers but for slow moving goods there is no force to stock in all dealers. Therefore an important decision in these systems is where and how much we should stock the slow moving goods and how each dealer can supplies its demand for slow moving goods. In this research we model this problem as a joint location-inventory model which locates some warehouses in the network to stock the slow moving goods and assigns the dealers to warehouses for calling the slow moving goods demand. This model also determines the optimal level of inventories for fast and slow moving goods. The proposed solution method is a hybrid algorithm of Tabu Search and greedy algorithm. The results show the performance of solution method is reasonable and also analytical results are presented
