基于模糊层次分析的森林防火瞭望台选址模型

Modeling the sitting of forest fire observatory based on fuzzy analytical hierarchy

选定影响森林防火瞭望台选址的11个主要因子,构建了层次分析模型,并引入三角模糊函数和模糊互补判断矩阵,提出用于森林防火瞭望台选址的模糊层次分析选址模型,克服了传统选址过程中的主观性,科学客观的对备选方案进行综合评价。以安宁市为例,得出备选方案的总权重分别为0.4241、0.3731、0.2028,从而确定第一方案最优。

By choosing eleven main factors which influence the sitting of forest fire observatory to build the analytic hierarchy model, We proposed fuzzy hierarchy analytic model for sitting of forest fire lookout tower by introducing the triangular fuzzy function and fuzzy complementary judgement matrix. This model can provide an objective way to evaluate the options instead of the subjective judgment in the traditional way. In case of Arming city, the total weight for each alternative solution is 0.4241、 0.3731、0.2028 respectively. Results show that the first solution is optimal.
