The Application of Analytic Hierarchy Process (AHP) in the Evaluation Technology Research for Lock Chamber Walls

Aiming at the aging disease of lock chamber walls, the evaluation research of lock chamber wall was carried out in this paper. The reliability of lock chamber was taken as the general goal. The safety, applicability and durability were taken as sub goals, and the sub goals’ affecting factors were used as hierarchy indicators. A multilevel and multifactor evaluation model including three hierarchies and eleven indicators was established. In this method, the analytic hierarchy process (AHP) was used to determine the primary indicator weights. The result shows that this method is practical and efficient, and easy to be operated. It can provide a reference for the repair of lock chamber walls.
