用权数区间构建运输方式选择模型

构建运输方式选择模型减少或避免运输方式选择的主观性。根据运输方式的各个单因素评价值的重要程度,构造对应的权数区间,使各因素的权数保持特定的关系,并计算运输方式的综合评价值的变化范围,由综合评价值与权数区间的关联关系获得权数区间决策图和权数关联图,通过检验、调整和固化权数区间,完成模型构建。通过模型来选择运输方式得到最佳的运输方式及对应的权数条件。

Selection Models of Transportation Modes Established by Weight Interval

Selection models of transportation modes were established to decrease or avoid the subjectivity of selection of transportation modes.According to the importance degree of each single factor evaluation value,the corresponding weight interval was wad set up to keep the specific relationship between the weights of each factor and the range of the transportation mode was calculated.In view of association of the comprehensive evaluation value and the weight interval,the decision diagram and the association graph were obtained.Then the weight interval was adjusted and identified by test to complete the establishment of the model.Finally,the best transportation mode and its weight restriction were obtained by selecting the transportation mode based on the model.
