In order to compress the lead time of supply chain, increase the response speed and raise the service level, the traditional newsboy model was extended to a newsboy problem with time windows.The impacts of lead time compression on supply chain and its member benefits were discussed.Under the condition of normal distribution of market demand function, the mathematics models of supply chain profit, manufacturers profit and retailers profit were established respectively.Through analyzing the changes of supply chain profit before and after the compression of lead time, it indicates that the newsboy problem model with time windows can increase the income of the supply chain, compared with the traditional newsboy model.The optimization plan of earnings coordination for the supply chain was given out.The optimal order quantity and the biggest cost increase coefficient of the supply chain were analyzed.The research conclusion was verified by numerical analysis.
