Abstract: Optimal pipeline planning is an emerging problem of the environment and economic development in uneven terrain areas that requires the most sophisticated scientific methods of path analysis. During the planning of the most suitable routes for the pipeline, the topography, proximity to the road, settlement, water resources, protected sites and other critical landmarks have always acted as an important role as a constraint. With the Application of Analytical Hierarchical Process, the suitability analysis to derive the relative preferences of the different factors affecting the route is achieved.
