摘要: 应急设施选址受应急物资需求量的影响。为优化应急设施选址布局,提高突发事件应急处置能力,以化工园区突发事件为研究背景,对化工园区突发事故下应急设施选址进行研究。考虑到化工园区突发事件的随机性和复杂性、突发事件应急物资需求的不确定性等特点,以应急设施选址安全性最大、经济性和服务效益最好为目标,基于传统确定性应急设施选址模型,构建了不确定需求条件下化工园区应急设施选址区间规划数学模型。模型中应急物资需求量是一个区间值,通过引入区间规划理论和模糊理论对模型进行求解,不仅避免了不确定参数随机概率分布的波动率,而且也降低了模型求解过程中的不确定性。最后,以园区各企业潜在事故为工程背景进行实例分析,得到园区应急设施的布局方案。结果表明,模型的求解效果较好,可为园区应急设施选址决策提供参考依据。

Abstract: The location of emergency facilities is affected by the demand for emergency materials. To optimize the location layout of emergency facilities and improve emergency response capabilities, the emergency response of chemical industry park is studied in this paper. Considering the randomness and complexity of emergency incidents in chemical industry park, and the uncertainty of emergency demand, a mathematical model for interval programming of emergency facility location in chemical industry park is established on the basis of the traditional deterministic emergency facility location. The model aims to maximize the safety, minimize the cost and optimize service efficiency of emergency facility location in the same time, and it assumes that the demand for emergency materials is an interval value. Then, the model is solved by introducing the interval programming theory and the fuzzy theory, which not only avoids the volatility of the random probability distribution of the uncertain parameters, but also reduces the uncertainty in the model solution. Finally, a case analysis is carried out based on the potential accidents of various enterprises in the park. And the reasonable layout plan of the emergency facilities in the park is obtained. The result shows that the model works well for the solution and provides a reference for the decision-making of the emergency facilities in the park.

Key words: emergency facility location, interval programming, fuzzy theory, chemical industry park
