供应阶段的供应链结构问题实质是产品零部件外包的数量问题.将0-1规划原理运用到零部件自制与外包的决策过程中,能较好解决多个零部件自制与外包的选择问题.建立0-1规划模型,通过模型求解,在达到总成本最低的目的下,得到最优外包零部件的数量.

英文摘要：

The problem of structure optimization in supply is essentially how to determine the outsourcing number of component. The problem of self-production and outsourcing about multiple components can be well solved if the 0-1 programming principle is applied to the self-production and outsourcing decision process of components. It can gain aim at optimization number of outsourcing components at the minimal total cost through establishing and operating the 0-1 programming model.
