指挥防护工程选址方案评价模型

摘要

The model, which is available to Command Protection Engineering (CPE) site selection, was built taking the complex characteristics into consideration.The weight of evaluation index was determined by improved Analytic Hierarchy Process (AHP), and was modified by entropy method.According to the characteristic of the evaluation index of CPE site selection, the combined method of the spatial information analysis and multi-expert group decision was adopted to achieve spatial and non-spatial index value.Grey Correlation Analysis (GCA) was used to improve Technique for Order Preference by Similarity to Ideal Solution (TOPSIS), avoided the limitation that traditional TOPSIS adopts Euclidean distance alone.This model can achieve an ideal evaluation result through an example.%根据指挥防护工程选址复杂性的特点,建立适合指挥防护工程选址的模型.采用改进的层次分析法(AHP)初步确定评价指标的权重,并用熵值法进行修正.根据指挥防护工程选址评价指标的特点.采用GIS空间分析和专家群决策相结合的方法获取空间和非空间指标值.利用灰色关联度分析(GCA)对理想解法(TOPSIS)进行改进,避免了传统TOPSIS单独采用欧氏距离的局限性.算例证明,该评价模型能得到理想的评价结果.
