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(More)
Using a real-life data set, we investigate the benefit of sharing market sales information in a setting where a theoretical model argues there is no benefit from such a collaboration scheme. The set of real Electronic Point Of Sales (EPOS) data and the orders that were placed by a retailer to a suppler was used. We have focused on products that operate(More)

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(More)
