基于分级的危险化学品运输风险评价研究

The Research of Hazardous Chemicals Transportation Risk Assessment Based on Classification

摘要:

随着我国经济持续快速的发展，对危险化学品需求快速增加。由于危险化学品其特殊的性质，一旦发生事故将比一般的运输事故有更大的破坏性，因此在运输中需要给予特别的关注。基于这样的背景，本文通过风险评价模型对危险化学品运输中的风险进行了分析。首先本文考虑了危险化学品运输中会发生的各种成本，然后将运输风险分级处理，并通过一定的函数形式转化为成本，从而将危险化学品的运输成本与风险成本在同一目标函数中表示，该模型可为政府制定政策减少风险以及企业选择合理的路径降低成本提供依据。本文将更多的因素考虑到风险评价模型中，从而增加了其准确性和实际意义。

Abstract: With China’s sustained and rapid economic development, the demand for hazardous chemicals is increasing. Due to the special nature of hazardous chemicals, the occurrence of an accident may lead to a more destructive result than the general transport accidents, so the transportation of hazardous materials needs special attention. Based on this background, this article analyses the risk of hazardous chemicals transportation through risk assessment model. First of all, this paper considers all kinds of cost in the transportation of hazardous chemicals, then classifies the transportation risk into different kinds, and by the ways of certain function forms this into cost, which will make hazardous chemicals transport cost and risk cost in the same objective function. This model can be used for the government to formulate policies to reduce the risk and help the enterprise choose a reasonable path lower the cost. This article considers more factors in the risk assessment model, thereby increasing the accuracy and practical significance.
