| 摘 要： | 为解决工程项目物流方案优化中因不同方案的风险差异给决策工作带来的困难,在决策网络计划方法的基础上,提出了能够同时表达多个离散随机样本空间的决策单元结构;并将随机规划方法引入模型的优化中,建立了综合考虑成本和风险的上界极小模型及求解算法.文中以某建设项目物流方案的优化对模型的有效性与实用性进行了验证.结果表明,该模型能够有效解决风险存在差异时工程项目物流方案的优选问题,因而具有较高的理论意义与实用价值. |

| Abstract: | To solve the difficulties resulting from risk differences in optimization of the project logistics scheme,we present a decision unit structure including several discrete sample spaces based on decision network planning technique.Stochastic programming theory is introduced in the optimization and an upper bound minimal model with consideration of both cost and risk is established. A case study is given to verify the effectiveness and practicability of the model.The result shows that the model can solve the o... |
