基于D-S证据理论的后方车材仓库管理水平综合评估

Comprehensive Evaluation of the Management Level of Rear Vehicle Materials Warehouse Based on D-S Evidence Theory

针对后方车材仓库管理水平评估中的不确定信息,将证据理论引入评估模型中。建立后方车材仓库管理水平评估指标体系,将专家模糊评语转化为评估等级的隶属度函数,利用证据可信度和指标权重对mass函数进行修正,运用D-S证据理论的Dempster合成公式对修正后的专家评估意见进行综合,得到最终评估结论。

In view of the uncertain information in the evaluation of rear vehicle materials warehouse management level, the D-S evidence theory is introduced into the evaluation model. An evaluation index system of rear vehicle materials warehouse management level is built ; the fuzzy comment of experts are transformed to membership function of evaluation grade ; mass function is corrected through evidence credibility and indicator weight. Then the Dempster combination rule of D-S evidence theory is used to integrate the corrected expert comments. Finally, the evaluation conclusion is get.
