We study a two echelon supply chain with AR(1) demand and unit replenishment lead-times. Each echelon of the supply chain uses conditional expectation to generate MMSE forecasts. Both echelons use these forecasts inside the “Order-Up-To” policy to generate replenishment orders. We investigate 3 different scenarios: The first is when each echelon aims to minimize their own inventory holding and ...

Coordination is very important in supply chain management and it is one of the main factors in supply chain profitability. Bullwhip effect is one of the basic obstacles to achieve coordination in supply chains and reduction of this phenomenon has an important role in supply chain harmony. The other side, costs of supply chain can be mitigated and customer service level can be increased by reduc...

In today’s globalization, the success of an industry is dependent on cost effective supply chain management under various markets, logistics and production uncertainties. Uncertainties in the supply chain usually decrease profit, i.e. increase total supply chain cost. Demand uncertainty and constraints posed by the every echelon are important factors to be considered in the supply chain design ...

This paper considers a two-echelon capacitated supply chain with two non-identical retailers and information sharing. We characterize the optimal inventory policies. We also study the benefits of the optimal stock rationing policy over the first come first served (FCFS) and the modified echelon-stock rationing (MESR) policies. © 2006 Elsevier B.V.

closed-loop supply chain network design is a critical issue due to its impact on both economic and environmental performances of the supply chain. in this paper, we address the problem of designing a multi-echelon, multi-product and capacitated closed-loop supply chain network. first, a mixed-integer linear programming formulation is developed to maximize the total profit. the main contribution...

We consider ex post demand information sharing and leakage in a two-echelon supply chain consisting of one supplier two retailers competing quantities. The incumbent retailer has an advantage to acquire about the market at cost. If he invests acquisition, privately acquires signal demand. examine incumbent’s incentive acquisition sharing, upstream supplier’s strategy. confirm that decisions dep...

This paper analyses an infinite horizon two-echelon supply chain inventory problem and shows that a sequence of the optimum ordering policies does not yield globally optimal solutions for the overall supply chain. First-order autoregressive demand pattern is assumed and each participant adopts the order-up-to (OUT) policy with a minimum mean square error forecasting scheme to generate replenish...

Joint managed inventory is an advanced supply chain inventory management tool, which will effectively tackle the complicated problem between the inventory cost of supply chain and service level. The research on inventory model and its’ control under JMI environment is a hot issue at present. In this paper, the authors deeply discuss the question of the inventory time costs about the multi-produ...

In this paper, we analyze the impact of a transportation disruption on supply chain performance by using system dynamics simulation. Performances of three different supply chains with Internet e-collaboration tools are compared with the assumption that a transportation disruption occurs within two echelons in a five-echelon supply chain. Numerical results are shown to reveal that from Non-colla...
