Minimizing the supplying cost of leverage items: a mathematical approach
In the new competitive environment, selecting and planning of the supply chain is very crucial and involves evaluation of many factors. Different approaches have been applied to assess the supplier/s. Most of these studies are based upon the supplier/s' capabilities.

متن کاملOptimal ordering quantities for substitutable deteriorating items under joint replenishment with cost of substitution
In this paper we develop an inventory model, to determine the optimal ordering quantities, for a set of two substitutable deteriorating items. In this inventory model the inventory level of both items depleted due to demands and deterioration and when an item is out of stock, its demands are partially fulfilled by the other item and all unsatisfied demand is lost. Each substituted item incurs a...
