Abstract:Performance evaluation of irrigation systems is a key issue in the field of irrigation system management. This paper presents a Ratio of Similar Priority (RSP) method for irrigation systems performance evaluation. The time series data from the Shi-jin Irrigation District in northern China is used to test the method. The results show that this RSP method can be used to identify the main temporal changes of irrigation system performance. It offers clear and quantified results in terms of irrigation system performance evaluation.
Keywords:irrigation system  performance evaluation  fuzzy set theory
