Market share and sales are important indexes to measure the success of new product launches; however, serious uncertainty of new product demand is the main difficulty to make decision for enterprise. Considering this, we describe the demand of new product with partial information, and design a new contract based on VMI, consignment and sales rebate. By means of the worst-case robust optimization approach, the improvement of corporation with the new contract is analyzed. The result shows that the new contract can control the risk of new product launches, improve market share, enhance enterprise benefit, and all of these would effectively support the new product launches.

The replenishment policy of VMI with one supplier and two-distributors is studied under stochastic demand and price subsidy mechanism is designed to coordinate the interests of the supplier and distributors after the implementation of VMI. Demand is assumed to obey normal distribution, and the transportation cost function is assumed to be piecewise. The safety stock and service level constraints are also taken into account. Results show that, total supply chain cost is reduced through the use of common replenishment epochs after VMI replenishment. When using equal allocation method in the coordination of interests, the supplier and distributors have different levels of profit improvement with the price factor designed. Finally, parameter sensitivity analysis shows that, the change of distributors' stock-out cost B has little effect on the price factor, while the changes of Ul (the average demand of distributor one), Sm (the supplier's fixed processing costs for each order of distributor one) and S1 (per order processing costs of distributor one before VMI) have different degrees of impact on price factor.
