Quantification method for public security vulnerability grade evaluation of refinery enterprise

The invention belongs to the technical field of public risk prediction, and discloses a quantification method for public security vulnerability grade evaluation of a refinery enterprise. The quantification method comprises the steps of determining an evaluation unit, constructing a public security vulnerability evaluation system, calculating evaluation factor weights, evaluating index values and calculating vulnerability grades, wherein the public security vulnerability evaluation system comprises 4 evaluation factors such as asset vulnerability, enterprise sensitivity, enterprise disaster bearing capacity and enterprise emergency capacity and 17 evaluation indexes such as asset layout and the like. According to the technical scheme, quantification of evaluation is achieved, and the evaluation result is more objective and reliable. 本发明属于公共风险预报技术领域，公开了一种炼化企业公共安全脆弱性等级评估的定量化方法，包括确定评估单元、构建公共安全脆弱性评估体系、计算评估因子权重、评估指标取值、计算脆弱性等级。其中公共安全脆弱性评估体系包括资产易损性、企业敏感性、企业承灾能力和企业应急能力四个评估因子以及资产布局等17项评估指标。本技术方案实现评估的定量化，使得评估结果更加客观、可靠。
