Petrochemical Enterprise Safety Performance Assessment Based On Interval Number

Safety performance assessment is the measurement of a petrochemical enterprise's achievement in safety management. In order to receive a comprehensive and objective evaluation result, it is necessary to consider all evaluation factors and the numerical uncertainty caused by fuzziness when safety performance assessment is conducted. To improve conventional safety performance evaluation, an evaluation index system is established, and the interval number is used in this study by using interval number to quantify scores and calculate the safety level of petrochemical enterprise safety. A case of petrochemical enterprise is used to illustrate the effectiveness of the method and system. This method is applied to the comprehensive evaluation of petrochemical enterprise safety to achieve good results.
