Among the 26 indicators, data for the qualitative indicators mainly come from a series of statistical yearbooks and RCS reports, while data for the quantitative indicators are obtained through scoring by more than 20 experts and calculating the average. The CRITIC objective weighting method is improved from three aspects of comparison intensity, correlation coefficient, and degree of variation, and the subjective weighting of indicators is carried out using the AHP 1\u20135 scale method. The optimal linear combination of subjective and objective weighting results is obtained using the combination weighting method with game theory, which is auxiliary to the set pair analysis. Considering the \u201ccertainty\u201d and \u201cuncertainty\u201d in the evaluation process, the four-element connection number model of set pair analysis is established to evaluate the implementation effect of the RCS in Henan Province from 2018 to 2021. The results show that the implementation effect of the RCS in Henan Province improves year by year and reaches excellent in 2019. The results of this study can be used as a reference for evaluating the work of the RCS in other regions and can also provide a reference for the study of evaluation problems in other fields.<\/jats:p>","DOI":"10.3390\/systems11090481","type":"journal-article","created":{"date-parts":[[2023,9,20]],"date-time":"2023-09-20T21:47:03Z","timestamp":1695246423000},"page":"481","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Evaluation Model and Application of the Implementation Effectiveness of the River Chief System (RCS)\u2014Taking Henan Province as an Example"],"prefix":"10.3390","volume":"11","author":[{"given":"Jianting","family":"Liu","sequence":"first","affiliation":[{"name":"College of Mathematics and Statistics, North China University of Water Resources and Electric Power, Zhengzhou 450046, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xuanyu","family":"Chen","sequence":"additional","affiliation":[{"name":"College of Mathematics and Statistics, North China University of Water Resources and Electric Power, Zhengzhou 450046, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9486-711X","authenticated-orcid":false,"given":"Limin","family":"Su","sequence":"additional","affiliation":[{"name":"College of Mathematics and Statistics, North China University of Water Resources and Electric Power, Zhengzhou 450046, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yanbin","family":"Li","sequence":"additional","affiliation":[{"name":"College of Water Resources Engineering, North China University of Water Resources and Electric Power, Zhengzhou 450046, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yanxue","family":"Xu","sequence":"additional","affiliation":[{"name":"Chinese Academy of Environmental Planning, MEP, Beijing 100012, China"},{"name":"Department of Hydraulic Engineering, Tsinghua University, Beijing 100084, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lei","family":"Qi","sequence":"additional","affiliation":[{"name":"College of Mathematics and Statistics, North China University of Water Resources and Electric Power, Zhengzhou 450046, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,9,20]]},"reference":[{"key":"ref_1","unstructured":"Bashir, I., Lone, F.A., Bhat, R.A., Mir, S.A., Dar, Z.A., and Dar, S.A.
