| 摘 要： | 介绍D-S证据理论的推理方法和组合规则。针对D-S证据理论方法不能对冲突证据进行组合的局限性,探讨适用于城市轨道交通系统型式选择问题的组合规则,给出通过基本概率赋值转移预处理后再组合的冲突证据组合方法。基于D-S证据理论的推理方法建立城市轨道交通系统型式选择决策模型,并应用文中提出的冲突证据组合方法进行求解。最后结合国内已建成轨道交通系统城市的7项指标,对济南市城市轨道交通系统型式选择进行融合决策,经检验证明该模型对城市轨道交通系统型式选择具有辅助决策作用。

| Abstract: | The reasoning method and combination rules of the D-S evidence theory are introduced.Because of the limitation that the D-S evidence theory can not make up the conflicting evidence,this paper discusses the combination rules of urban rail transit system type selection and proposes the method of conflicting evidence combination applied after transfer pretreatment of basic probability assignment.The type selection decision model of the urban rail transit system is developed on the basis of the D-S evidence the... |
