为保证危险品运输安全,快速到达目的地,应用多属性决策理论对危险品运输的最佳路径进行了研究。装载危险物品的列车是一种动态危险源,一旦发生事故,会对人民的生命财产造成巨大威胁。科学合理的运输路线选择是保障危险品运输安全的必要条件。在混合语言环境下,采用三角模糊数和区间数表示不确定变量,建立拉格朗日函数,通过计算偏导数得到权向量,通过计算在理想投影上的路径投影算子值确定最佳运输路径。实例验证了该决策方法的可行性。该方法有助于相关部门在混合语言环境下选择合理的运输路线。
In order to insure transportation safety and reach destination rapidly, the best transportation route of hazardous materials is studied with multi-attribute decision-making theory. The train loaded with the hazardous material is one kind of dynamic hazardous source, once it encounters the accident, it can cause the huge threat to the people's lives and properties. The scientific and reasonable choice for transportation route is the essential condition which safeguards the transportation security of hazardous materials. Under the hybrid language environment, the triangular fuzzy number and the interval number are used to express the uncertain variable, then the Lagrange function is established and the weighting vector is obtained by calculating partial derivative, and the best transportation route is ascertained through calculating the route projection operator value which displays on the ideal projection. The example confirms the decision-making method is feasible. The method is helpful for the relevant department to choose the reasonable transportation route under the hybrid language environment.
