中文摘要：

在一个由供应商和零售商组成的供应链系统中，需求通常与零售商向客户承诺的交货期和产品价格相关，产品价格又与交货期相关。基于此，建立零售商和供应链向客户承诺的交货提前期、产品价格和能力扩张联合决策模型。研究结果表明，与零售商单独决策相比，在供应链一体化决策情形下，如果终端客户为提前期敏感型，零售商向客户承诺的交货提前期越短产品价格越高；如果终端客户为价格敏感型，则其向客户承诺的交货提前期越长产品价格越低；不论是何种类型的客户，随着零售商对交货提前期和产品价格的调整，市场需求都会增加，并要求零售商扩张其能力。为了使供应链利益最优和自身受益，供应商可以通过对零售商的能力扩张进行补贴的方式激励零售商调整其向客户承诺的交货期和产品价格，并进行相应的能力扩张，而产品转移价格越高，供应链通过协调获得的增量利润也越多。

英文摘要：

The paper models a supply chain consisting of a supplier and a retailer in a situation where the mean demand rate has relation to the guaranteed delivery time offered by the retailer to the customers and the market price, while the price itself is determined by the length of the delivery time. A mathematical framework is proposed to understand the interrelations among delivery time guarantee, pricing and order processing capacities of the retailer. The model and numeral analysis illustrate that when customers are Lead-time-sensitive type, the guaranteed delivery time of the retailer is shorter and the pricing of products is higher in the integrated decision than in the decentralized decision, but when customers are price-sensitive, the situation is the opposition. The demand is higher and the retailer needs greater order processing capacities in the integrated decision than in the decentralized decision. The paper then shows that the supplier can facilitate the retailer to add the capacities and to maximize the profits of whole supply chain by sharing in adding profit to the retailer, and the higher the transfer price, the more the adding profit of the supply chain via coordination.
