Evaluation and routing of power transmission lines by using AHP method and genetic algorithm

Today optimization is one of the most important issues in all engineering fields. According to importance of this issue in planning power transmission lines, appropriate areas have been accreted for numerous researches. Widespread usages of GIS application and its combination with GA base methods offer practical solution for power transmission lines design. In this paper, we first study about efficient criteria for selecting appropriate points for installing towers, and then we can evaluate available points for installing power towers by one of the multi-criteria decision-making analysis, named Analytic Hierarchy Process. As we know, all of these nodes are not suitable for being one of the transmission line Points. So by using this procedure (AHP) we calculate cost function of transmission line between towers. Finally, with GA algorithm, the best and the most optimum route between source and destination will be selected.
