Abstract: A policy of coordinating inventory by Common Replenishment Epoch (CRE) for a kind of lot-to-lot supply chain was studied and analyzed. In this supply chain， single supplier provided single product to multi-retailers with stochastic demand. Under the proposed policy of coordinating inventory， when the retailers accepted CRE provided by supplier， the supplier offered retailers a price discount. Retailers could accept or refuse the policy of coordination， which meant that the price discount to the retailers was selective. Finally， a numerical study and simulation analysis was conducted. Result of simulation confirmed that the policy could reduce the cost of supplier， and the increased cost of retailer could be compensated by price discount so as to reduce the total cost of supply chain.
