Assessment Model of Accident Emergency Management System Performance for Chemical Industrial Park Based on Immune Mechanism

Abstract

Chemical accidents happen in workplaces all around the world. To improve the accident emergency management system is an important methodology to reduce the casualty and loss caused by accidents. In the light of the principles of immune system, the paper tried to analyze the accident emergency management system of chemical industrial park. It elaborated the similarities between immune system and accident emergency management system in the aspects of their existing environment, action object, function and adjustment mechanism. Immune mechanisms were used to formulate the assessment indexes of accident emergency management system performance. Inspired by immune system that keeps the living body healthy in “no antigen condition” and “touching antigen condition”, the assessment index system was formulated from the perspectives of “non-emergency condition” and “emergency condition”. Through the improved analytic hierarchy process, the weights of assessment indexes were calculated. Furthermore, the linear weighted model was applied in the building of the assessment model, which was then used to analyze the accident emergency management system of a chemical industrial park in Guangdong province, China. Through the data from expert investigation questionnaires, the scores of nine assessment indexes reflected accident emergency management system performance were obtained. The result showed that the model is helpful in analyzing the accident emergency management system performance and in improving the accident emergency management system in chemical industrial parks.
