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。 Eleven main factors influencing the site selection of forest fire prevention observatory are selected, and the AHP model is established. The trigonometric fuzzy function and the fuzzy complementary judgment matrix are introduced, and the fuzzy AHP model for the site selection of forest fire prevention observatory is proposed. The subjectivity in the process of traditional site selection, scientific and objective evaluation of the options for comprehensive evaluation. Taking the city of Anning as an example, the total weight of the alternatives is obtained as 0.4241, 0.3731 and 0.2028, respectively, so as to determine the optimality of the first solution.
