摘要: 〖HT5”H〗摘要: 〖HTSS〗为了合理地确定不同运输方案的风险等级,为危险品生产企业提供运输决策支持,构建了危险品运输风险评价指标体系,提出了群决策环境下危险品运输风险评价方法。该方法应用模糊语言术语来表达评价值,基于专家评价值的一致度来修正专家初始权重,利用综合赋权法确定评价指标的权重,引入格贴近度确定不同运输方案的风险等级。该方法有效地降低了风险评价工作的复杂性。最后以某危险品运输为例,验证了该方法的可行性和实用性。

Abstract: In order to reasonably determine the risk level of different transport plans and support manufacturers-transport decision, a set of hazmat transportation risk evaluation index system is constructed and a risk evaluation method is proposed in a group decision environment. Fuzzy linguistic terms are introduced to represent experts judgment information. The degree of consistency of experts- judgment information is used to modify the experts weights. A comprehensive assigning weight method is used to determine the weights of the evaluation index system. Furthermore, the lattice degree of approaching is adopted to calculate the risk result. The proposed method can greatly reduce the complexity of the risk assessment. Finally, using an example from some dangerous goods transport, the method is shown to be effective and feasible.

Key words: hazardous material transportation, risk evaluation, group decision, comprehensive assigning weight method
