供应链管理环境下军用物资多品种采购的多供应商选择研究

How to Select Multi-supplier for Multi-item Military Materials Procurement in SCM

为解决供应链管理环境下军用物资采购多供应商选择问题,建立了以供应综合成本最低为目标函数,满足多个约束条件的组合优化模型。为解决求解的困难,采用变换分解算法,将原模型转换为整数规划问题。根据不同迭代方式,给出了两种基本运算步骤。算例分析表明:该新方法克服了常规供应商选择评价方法只针对单一物资供应过程和面向单一供应商选择过程的局限性。

The paper establishes an optimized composite model which takes the lowest integrated supply costs as the objective function and is with some necessary constraints, uses a decomposing algorithm to transfer the original model into an integer programming model and presents two basic algorithms based on different procedure.
