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. The dangerous StemRegenin 1 solubility goods refer to a kind of materials and goods which is flammable, explosive, toxic, strongly corrosive and heavily radioactive, and so

forth [1]. Any links may easily cause accidents which can endanger people’s life and property and pollute the environment in the process of transportation. Just for these special characteristics, it is extremely important to make safety assessment of dangerous goods transport enterprise. At present, there are few available studies on safety assessment of dangerous goods transport enterprise in our country. For instance, Xiu and Zhang established the evaluation index system and fuzzy synthetic evaluation model used for safety management of dangerous goods transport and then assessed the safety of dangerous goods transport enterprise [2]. Huo et al. applied Likert-type scale based on Matter Element Analysis theory to assess the safety of dangerous goods transport enterprise [3]. 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]. In foreign countries, they focused on the dangerous goods transport routes

optimization, risk assessment, emergency tube principle, and the development of decision support system research [5–9]. Above studies have provided a theoretical reference to assess the safety of dangerous goods transport enterprise, but they still need further improvement in aspects of index value and weight assignment. For instance, a certain index value in index system of safety assessment of dangerous goods transport enterprise may change with the passage of time, change of environment, affection of inner or outer factors, and shift of personal subjective wishes. It will not be accurate enough on assessment result in certain degree if they are assessed as static indexes. Moreover, because of the existing diversity on knowledge, experience, and preference among the experts, giving the same weight value may not be objective. Therefore, this paper researches on the safety assessment GSK-3 of dangerous goods transport enterprise using optimization model based on relative entropy in group decision making. 2. The Safety Assessment Model of Multiobjective Dangerous Goods Transport Enterprise Based on Entropy Suppose A = a j, j = 1,2,…, n is a dangerous goods transport enterprise set to be assessed, wherein a j is the enterprise j; and B = b i, i = 1,2,…, m is a set of assessment indexes from experts, wherein b i represents index i. Namely, there are total n experts to make an assessment on m indexes in an assessment program.
