摘要
为了提高重大危险源风险评估的有效性,采用灰色系统关联度原理,将灰关联分析方法应用于重大危险源风险评估.根据系统安全工程理论,建立了重大危险源评价指标体系,并计算评价指标中的各子系统相对于各个标准评价等级的关联度,然后对各子系统进行较高层次上的综合,以综合结果排序,按隶属度最大原则,确定了重大危险源的风险等级,并开发了原型系统.实例分析表明,本方法简便易行,且结果与实际较为吻合,对重大危险源评估具有较好的适用性.
In order to improve the availability of major hazard installations risk evaluation, grey relational evaluation is presented based on the principle of association degree of the grey system. According to safety engineering theory, evaluation indexes system and weight are established by means of layered analytical method, and association degree of every subsystem to every standard grade is computed. Then in a high level, the association degrees of every subsystem are synthesized, and the result is sorted from low to high to determine major hazard installations grade. Moreover, a prototype system is developed. Analyses on some examples show that this method is effective and applicable to major hazard installations risk evaluation.
