A Quantitative Judgement Method for Safety Admittance of Facilities in Chemical Industrial Parks based on G1-Variation Coefficient Method

This paper aims to introduce a new quantitative method for safety admittance of facilities based on G1-variation coefficient method in chemical industrial parks. As is known, at present mass incidents resisting the hazards of chemical facilities were happened in China frequently. In order to alleviate such prominent contradictions, from the perspective of safety admittance of facilities in chemical industrial parks, the judgement criteria and indexes were put forward. Then the subjective G1 method and the objective variation coefficient method were used to determine the weights of criteria and indexes. And the quantitative judgement model was established. At last, an empirical research was conducted. The results show that the judgement criteria and indexes proposed in this paper include four criteria and nine indexes. And the weight of environment bearing is higher based on subjective evaluation, complying with the people's risk perception of chemical facilities’ hazards. While the weights of economic effect and safety management are higher than others based on objective evaluation, in line with the current situation that how chemical industrial parks to choose the suit facilities for entering.
