Application of varying coefficient discrepancy degree in water quality evaluation of water supply networks

摘要：

　　Set pair analysis (SPA) is a new method to describe and process the system uncertainty and has been applied in many areas recently.In view of the uncertainty and complexity in the process of water quality evaluation of water supply networks,the paper introduced a new model-varying coefficient of discrepancy degree based on set pair analysis theory.In the model,a new effective method to the determination of discrepancy degree coefficient i is suggested.As an example,the paper evaluated water quality conditions of water supply networks from 3 monitoring spots by the model.The results of the assessment are in concordance with other evaluation methods.Compared with the other evaluation method,this model is perfect,the evaluating result is more reasonable and its resolving power is higher.
