基于Grey-DEMATEL的农产品冷链物流影响因素分析

Analysis of Affecting Factors of Agricultural Products Cold Chain Logistics Based on Grey-DEMATEL

提出将区间灰数与DEMATEL相结合的方法,解决了传统DEMATEL方法在打分时数值过于确定而忽略了不同企业的差异的问题.利用区间灰数的柔性解决了在评价中因素选择的模糊性和不确定性,构建出更具柔性且符合实际的Grey-DEMATEL方法决策模型.建立了基于区间灰数理论的农产品冷链物流影响因素关系矩阵,运用MATLAB求解出影响农产品冷链物流的综合影响矩阵,定量地分析了影响农产品冷链物流的关键影响因素,为进一步优化农产品冷链物流奠定了基础.

The method of combining the interval gray number with DEMATEL is proposed to solve the problem that the traditional DEMATEI~ method is too certain in scoring and ignores the difference between different enterprises. The flexibility of interval gray number is used to solve the ambiguity and uncertainty of factor selection in evaluation, and a more flexible and realistic Grey-DEMATEL method decision model is constructed. Based on the interval gray number theory, the relationship matrix of the influencing factors of agricultural cold chain logistics is established. The comprehensive impact matrix affecting the cold chain logistics of agricultural products was solved by MATI^AB, and the key influencing factors affecting the cold chain logistics of agricultural products were quantitatively analyzed, which laid a foundation for further optimizing the cold chain logistics of agricultural products.
