Nacrtak将GIS工具与层次分析法（AHP）技术相结合，开发了一个决策支持系统，用于根据实际情况和需要对林区公路网的养护优先级进行排序。决策过程分为4个阶段。第一阶段确定分析的目标为路面产沙量最小化和道路社会价值最大化。第二阶段定义决策问题的层次结构。在这一阶段，确定了使每个目标最大化的一组因素（标准）和评价方法。在第三阶段，使用在ArcGIS上运行的特定应用程序应用AHP分析，根据设定的目标计算代表每条道路重要性的评价层。在第四阶段使用评估层的值，根据给定的效益对维护干预措施进行排序。该方法已在一个森林公路网进行了测试，延伸107.8公里，包括在分析中的真实的预算限制和维护成本。结果表明，GIS和AHP分析的综合使用是一个有价值的工具，以率的重要性，森林公路网的山区管理和确定优先级之间的维护业务的道路网络，以最大限度地提高整体效益与有限的经济资源。
Nacrtak The combination of GIS tools and Analytic Hierarchy Process (AHP) techniques is used to develop a Decision Support System to rank the maintenance priorities of a forest road network according to the actual conditions and needs. The decision-making process is divided into 4 stages. The first stage fixes the objectives of the analysis as the minimization of the sediment production from road surface and the maximization of the social value of the road. The second stage defines the hierarchical structure of the decision problem. At this stage the set of factors (criteria) to maximize each objective and the evaluation methods are defined. At the third stage AHP analysis is applied using a specific application running on ArcGIS, to calculate the evaluation layer that represents the importance of each road according to the set objectives. The values of the evaluation layer are used at the fourth stage to rank the maintenance interventions according to the given benefit. The methodology has been tested in a forest road network with an extension of 107.8 km including in the analysis the real budget constraints and maintenance costs. The results show that the integrated use of GIS and AHP analysis represents a valuable tool to rate the importance of the forest road network for the management of a mountain territory and to define priorities among maintenance operations of the road network, in order to maximize the overall benefit with limited economic resources.
