Comparison and Selection of Water Intake Methods for Large Amplitude Water Level Pumping Stations Based on CM-FAHP
In order to improve the rationality of the evaluation of water intake methods for large amplitude water level pumping stations,a set of evaluation index system for water intake methods of large amplitude water level pumping stations was established.It combined the Cloud Model(CM)with Analytic Hierarchy Process(AHP)and Entropy Weighting Method(EWM)to assign subjective and objective weights to each evaluation indicator,proposed a comprehensive evaluation method for the water intake mode of large amplitude water level pumping sta-tions based on the combination of CM and Fuzzy Analytic Hierarchy Process(FAHP),and used the cloud model comprehensive similarity comparison method to determine the optimal water intake plan.Taking the comprehensive utilization and replacement of water resources in the First Phase of the Erhai Lake Water Supply Project in Ludila,Yunnan Province as an example,practical application was carried out.The re-sults show that the comprehensive evaluation cloud maps of the four water intake schemes(vertical shaft dry chamber pump room,rack wet chamber pump room,floating boat pump room and cable car pump room)are all located between the evaluation levelⅢand levelⅣstand-ard cloud maps,the comprehensive evaluation cloud map of the floating boat pump station has the highest similarity with the cloud map of the Grade Ⅳ standard,indicating that the water intake method of the floating boat pump room is the optimal solution.
