英文摘要：

From the present literature about studies on linear optimal models of the＇ supply chain and based on linear programming,the paper providesa new method to improve the optimal value of the objective function by adjusting the technique coefficients, without changing the structure of the LP＇s optimal solution. And this provides an effective technology and tools for the quantitative analysis during the supply chain system＇s optimization and re-organization process.
