摘要
滑坡灾害治理工程是一个复杂系统工程 ,治理方案的决策受到技术、经济、环境以及风险等许多因素的影响 ,不同专家决策者对治理方案有明显的偏好 ,且属性权重信息不能完全确知。为了处理这样的不完全信息和偏好决策问题 ,提出了一种基于相似度的对方案有偏好的三角模糊数型多属性决策方法。该方法首先建立一个线性规划模型 ,通过求解该模型获得属性权重 ,然后 ,采用三角模糊数来建立判断矩阵 ,对滑坡灾害治理方案进行优化决策。最后 ,以三峡库区榨坊坪滑坡灾害的治理决策为实例 。
The treatment of landslide hazard is a complex systems engineering. The selection of its treatment schemes is depended on many factors such as technology, economics, environment, and risk. Policymakers have preference information on alternatives, and the attribute weight information is incomplete. To cope with such decision-making question with incomplete and preference information, a similarity degree-based method for triangular fuzzy number multi-attribute with preference information on alternatives is proposed. By using this method, a linear programming model is established firstly, and the attribute weights are derived by solving this model, then, based on a possibility degree formula for comparing two triangular fuzzy numbers and a formula for priorities of complementary judgment matrix, a priority method for alternatives is presented. Finally, the method is applied to the decision-making of Zhafangping landslide in the Three Gorge reservoir area, and a good result is gained, which shows that the method is feasible and effective.
