Material Selection Techniques of Water Supply Pipe based on Analytic Hierarchy Process

The major problem of pipes used in Water Supply System (WSSs) were analyzed and the generally, used pipe and their major features were introduced in this study. The principles that the selection on Water Supply Pipes (WSP) should follow were pointed out. Analytic Hierarchy Process (AHP) using nine scaling was applied to optimize WSPs quantitatively. The optimal WSPs were determined according to the sorting result of comprehensive evaluation index. It could provide the reference to select the reasonable WSPs for the engineers.
