摘　　要：化学过程工业中安全是首要因素。传统的安全评价方法仅揭示化工厂当前的风险程度和安全水平,为了反映化工厂面临内外部变更时避免事故和减少事故损失的能力,提出了化工厂弹性指数。在应用层次分析法和模糊综合评价法分析化工厂的危险容忍能力的基础上,结合本质安全指数,给出了弹性指数的计算方法。案例研究表明,弹性指数能反映化工厂弹性的大小,可以协助管理人员在生产和安全间做出正确决策,在确保安全的同时尽可能追求高产高效。Safety should always come first in the chemical process industry. Traditional methods used to assess safety just reveal the degree of risk or the level of safety. In order to reflect the ability of avoiding accidents or reducing the lost caused by accidents in the face of internal and external changes, the Resilience Index （RI） of a chemical plant is proposed. Based on the evaluation of the hazard tolerance capacity by means of analytic hierarchy process （AHP） and fuzzy comprehensive evaluation method, combining with the Inherent Safety Index （ISI） of the chemical plant, the detail of the method to calculate RI is presented. The case study demonstrates that RI can reflect the degree of the resilience of a chemical plant. As a dynamic and explicit indictor, RI can assist managers to make a proper decision to balance production and safety, and therefore the chemical plant can strive towards states of as high performance as possible, while still being safed.
