- چکیده:
- چکیده انگلیسی: This paper studies the economic-order-quantity model (EOQ) for deteriorating items in two cases (with and without shortages) to evaluate how vendor managed inventory (VMI) affects supply chain. We consider two-level supply chain (single supplier and a single retailer) with one instantaneous deteriorating item. A numerical example and sensitivity analysis are provided to illustrate the effect of related parameters on total cost and optimal order quantity of two systems. The results show that VMI works better and delivers lower cost in all conditions than traditional supply chain (the system before implementation of VMI).

- چکیده:
- چکیده انگلیسی: This paper develops an economic production quantity model in a three-layer supply chain with two different structures. This chain composes of a supplier, a manufacturer, and multiple retailers. In this chain, the supplier transforms raw material to the semi-finished product, and sends them to the manufacturer. Then, the manufacturer transmutes them to the finished product, and delivers them to the retailers to satisfy market demand. The retailers replenish their inventory at the same time. The demand of each retailer is different due to essence of various demand customers, and according to the decisions of the chain’s members, two structures of non-integrated and integrated supply chains are surveyed. In this paper, we will employ the Stackelberg approach to solve the presented models. The ordering cycle of retailers is the decision variable of the model. The main aim of this study is to develop an inventory and production model in three-layer supply chains to minimize the total cost of chain by utilizing the optimal inventory control policy. At last, numerical examples are presented for each structure of supply chains.

- چکیده:
- چکیده انگلیسی: This paper develops a closed-loop supply chain including one manufacturer, one retailer and a third party, in which the manufacturer produces a product under appropriate quality and sells it through a retailer in the market. The retailer pays the expense of marketing effort and a third party collects the used products from consumers and sends to the manufacturer. The manufacturer remanufactures the recived second hand products such that the quality of the remanufactured items bacome as same as the new ones. We use two different Stackelberg games, and the decision vraibles of the model are the quality level, marketting expenditure, whole sale and retail prices. After investigating the concavity of the profit functions, the optimal closed-form solutions for all decision varaibales are derived. Subsequently, to show the applicability of the proposed models, a numerical example is presented and a sensitivity anslysis is then conducted to investigate the effects of key parameters on the values of decision variables.
