Application of Analytic Hierarchy Process in Quality Evaluation of Water Supply and Drainage Project

The quality of a building's water supply and drainage installation directly affects the use value and safety performance of this building. With the development of society, the traditional building water supply and drainage engineering is facing great challenges, because traditional building technology has not been able to meet recent marketing demand. In order to adapt to the marketing demands, we need to fix many risks, such as risk of new technology development and application, project construction and market risk. With the continuous updating of technology, people need a higher level of science and technology, to enhance the technology of water supply and drainage engineering. The construction quality control and management is very important to prevent the occurrence of quality problems and to enhance the safety factor of the building. In this paper, we apply analytic hierarchy process into quality evaluation system. Aiming at the risk factors of high level building's water supply and drainage, we provide the basis for management decision.
