Abstract

Safety of dangerous goods transport is directly related to the operation safety of dangerous goods transport enterprise. Aiming at the problem of the high accident rate and large harm in dangerous goods logistics transportation, this paper took the group decision making problem based on integration and coordination thought into a multiagent multiobjective group decision making problem; a secondary decision model was established and applied to the safety assessment of dangerous goods transport enterprise. First of all, we used dynamic multivalue background and entropy theory building the first level multiobjective decision model. Secondly, experts were to empower according to the principle of clustering analysis, and combining with the relative entropy theory to establish a secondary rally optimization model based on relative entropy in group decision making, and discuss the solution of the model. Then, after investigation and analysis, we establish the dangerous goods transport enterprise safety evaluation index system. Finally, case analysis to five dangerous goods transport enterprises in the Inner Mongolia Autonomous Region validates the feasibility and effectiveness of this model for dangerous goods transport enterprise recognition, which provides vital decision making basis for recognizing the dangerous goods transport enterprises.

Highlights

With the rapid development of society and continuous improvement of domestic economy in our nation, the occupations of the dangerous goods transport accounted in the entire transport system have been constantly raised
While Yan and his partners integrated the Fuzzy Decision theory, group decision making, and TOPSIS, put forward a method to make safety assessment of dangerous goods transport enterprise based on Fuzzy TOPSIS [4]
We can transform the relative entropy model based on group decision making, by minimizing the difference between preference utility value of each expert and preference vector of group, to nonlinear programming problems as follows: min s.t

Summary

Introduction

With the rapid development of society and continuous improvement of domestic economy in our nation, the occupations of the dangerous goods transport accounted in the entire transport system have been constantly raised. According to dynamic multivalue background, we adopt the following steps to establish a safety assessment model of multiobjective dangerous goods transport enterprise based on entropy. Through the above-mentioned model of safety assessment of multiobjective dangerous goods transport enterprise based on entropy [12, 13], each expert had calculated the value of. We can transform the relative entropy model based on group decision making, by minimizing the difference between preference utility value of each expert and preference vector of group, to nonlinear programming problems as follows: min s.t. Summing up what we discussed above, we draw the procedure diagram of safety assessment of dangerous goods transport enterprise based on the relative entropy aggregation in group decision making model (see Figure 1)
