An approach for identifying and selecting the route alignment using GIS and fuzzy AHP is developed in the present study. Spatial multi-criteria decision analysis is applied to identify optimal route alignment with the consideration of criteria such as environmental, social, economic and technical spatial datasets. These criteria play a significant role in the identification and selection of optimal route alignment. Fuzzy set theory is used to handle vagueness-type uncertainty in the multi-criteria decision analysis. Fuzzy AHP is introduced to compare the fuzzy criteria for ranking purpose, and fuzzy criteria weights are used to develop relative surface cost maps. The least-cost path (LCP) method is applied to find alternate four route alignments from source to destination by considering several criteria in GIS. The criteria values of each four alignment and weight of each criterion on the basis of maximum priority weight are calculated. The designed four routes are evaluated using priority weight method and fuzzy-AHP method. The selection of optimum route is considered by maximum weight of the alignment. The technical route alignment (alignment 4) is considered as optimum route with weight value 80.38%. The proposed methodology is implemented for a study area, outer region of Allahabad city, India.

基于模糊AHP的多准则决策分析，用于使用地理信息系统（GIS）的路线调整计划

本研究开发了一种使用GIS和模糊AHP识别和选择路线路线的方法。应用空间多准则决策分析来确定最佳路线路线，并考虑诸如环境，社会，经济和技术空间数据集之类的准则。这些标准在确定和选择最佳路线路线中起着重要作用。在多准则决策分析中，使用模糊集理论来处理模糊性类型的不确定性。引入模糊层次分析法（AHP）来比较用于排名目的的模糊标准，并且使用模糊标准权重来开发相对表面成本图。通过考虑GIS中的几个标准，应用了成本最低的路径（LCP）方法来查找从源到目的地的备用四个路线路线。根据最大优先权重，计算每个四个比对的标准值和每个标准的权重。利用优先权重法和模糊AHP法对设计的4条路线进行评估。最佳路线的选择取决于路线的最大权重。技术路线路线（路线4）被认为是最佳路线，权重值为80.38％。拟议的方法是针对印度阿拉哈巴德市外围地区的研究区域实施的。
