Abstract
As chemical industry has developed rapidly, some problems for our society have appeared, especially the problems related to chemical risk management. Because density of dangerous chemical products is relative high and components of chemical products are relative complex, it may increase the probability that dangerous chemical risk happens. Thus, for chemical enterprises, they not only need to improve economical level, but also need to control risk management. Meanwhile, although the existing studies have been focused on risk management of chemical industry, there are still some problems such as a rational method to assess chemical risk. In order to overcome these problems, this paper develops a new chemical risk assessment method based on group decision making method by considering group consensus of all chemical experts according to an advanced threshold. 2-tuple fuzzy linguistic term set is introduced to help the chemical experts express their risk assessments and final result analysis demonstrates that the proposed method is applicability in chemical risk assessment.
