In this study, all of the necessary formulations are re-derived and necessary modifications are proposed.<\/jats:p><\/jats:sec><jats:sec><jats:title content-type=\"abstract-subheading\">Research limitations\/implications<\/jats:title><jats:p>A corrected WASPAS equation for optimal combination parameters is derived. Two examples are used to validate the formulations, and software implementation is provided. Because multiple attribute decision-making (MADM) has gained widespread attention from both the academia and industry, the findings of this paper help decision makers fully capitalize the concept of ranking accuracy and avoid possible confusions regarding the equations reported in the literature.<\/jats:p><\/jats:sec><jats:sec><jats:title content-type=\"abstract-subheading\">Originality\/value<\/jats:title><jats:p>WASPAS is a relatively new MADM method and has enjoyed a visible position in the MADM literature. In addition to its simplicity, the WASPAS method utilizes the concept of ranking accuracy by combining the well-known WSM and WPM. This combination realized via an optimization criterion brings unique opportunities for decision makers such as evaluating confidence intervals for relative significance of alternatives and reducing estimated variance of ranking results. Despite its crucial importance, the combination of WSM and WPM is usually performed on an<jats:italic>ad hoc<\/jats:italic>basis in the literature. In this study, all of the necessary formulations are re-derived and necessary modifications are proposed along with clarifying examples.<\/jats:p><\/jats:sec>","DOI":"10.1108\/k-01-2019-0052","type":"journal-article","created":{"date-parts":[[2019,7,16]],"date-time":"2019-07-16T05:38:50Z","timestamp":1563255530000},"page":"885-895","source":"Crossref","is-referenced-by-count":40,"title":["Revisiting ranking accuracy within WASPAS method"],"prefix":"10.1108","volume":"49","author":[{"given":"Adil","family":"Baykaso\u011flu","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"\u0130lker","family":"G\u00f6lc\u00fck","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"140","reference":[{"issue":"8","key":"key2020022015441664600_ref001","doi-asserted-by":"crossref","first-page":"1629","DOI":"10.1080\/00207549108948036","article-title":"Computer aided robot selection: the \u2018multiple attribute decision making\u2019 approach","volume":"29","year":"1991","journal-title":"International Journal of Production Research"},{"issue":"1","key":"key2020022015441664600_ref002","article-title":"Applications of WASPAS method as a multi-criteria decision-making tool","volume":"49","year":"2015","journal-title":"Economic Computation and Economic Cybernetics Studies and Research"},{"issue":"5","key":"key2020022015441664600_ref003","doi-asserted-by":"crossref","first-page":"728","DOI":"10.3846\/13923730.2013.812578","article-title":"Assessment of health and safety solutions at a construction site","volume":"19","year":"2013","journal-title":"Journal of Civil Engineering and Management"},{"key":"key2020022015441664600_ref004","doi-asserted-by":"crossref","first-page":"265","DOI":"10.1016\/j.asoc.2017.03.045","article-title":"A systematic review and meta-analysis of SWARA and WASPAS methods: theory and applications with recent fuzzy developments","volume":"57","year":"2017","journal-title":"Applied Soft Computing"},{"key":"key2020022015441664600_ref005","volume-title":"Statistics for Engineers and Scientists","year":"2015","edition":"4th ed."},{"issue":"3","key":"key2020022015441664600_ref006","doi-asserted-by":"crossref","first-page":"303","DOI":"10.1016\/0167-9236(89)90037-7","article-title":"An examination of the effectiveness of multi-dimensional decision-making methods: a decision-making paradox","volume":"5","year":"1989","journal-title":"Decision Support Systems"},{"key":"key2020022015441664600_ref007","doi-asserted-by":"crossref","first-page":"653","DOI":"10.1016\/j.enconman.2014.05.083","article-title":"Assessment of regions priority for implementation of solar projects in Iran: new application of a hybrid multi-criteria decision making approach","volume":"86","year":"2014","journal-title":"Energy Conversion and Management"},{"issue":"4","key":"key2020022015441664600_ref008","doi-asserted-by":"crossref","first-page":"601","DOI":"10.15388\/Informatica.2006.158","article-title":"Evaluation of ranking accuracy in multi-criteria decisions","volume":"17","year":"2006","journal-title":"Informatica"},{"issue":"6","key":"key2020022015441664600_ref009","first-page":"3","article-title":"Optimization of weighted aggregated sum product assessment","volume":"122","year":"2012","journal-title":"Elektronika ir Elektrotechnika"},{"issue":"17","key":"key2020022015441664600_ref010","doi-asserted-by":"crossref","first-page":"7111","DOI":"10.1016\/j.eswa.2013.06.040","article-title":"Decision making on business issues with foresight perspective; an application of new hybrid MCDM model in shopping mall locating","volume":"40","year":"2013","journal-title":"Expert Systems with Applications"}],"container-title":["Kybernetes"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.emerald.com\/insight\/content\/doi\/10.1108\/K-01-2019-0052\/full\/xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.emerald.com\/insight\/content\/doi\/10.1108\/K-01-2019-0052\/full\/html","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,7,24]],"date-time":"2025-07-24T21:46:29Z","timestamp":1753393589000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.emerald.com\/k\/article\/49\/3\/885-895\/267123"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,7,8]]},"references-count":10,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2019,7,8]]}},"alternative-id":["10.1108\/K-01-2019-0052"],"URL":"https:\/\/doi.org\/10.1108\/k-01-2019-0052","relation":{},"ISSN":["0368-492X","0368-492X"],"issn-type":[{"value":"0368-492X","type":"print"},{"value":"0368-492X","type":"print"}],"subject":[],"published":{"date-parts":[[2019,7,8]]}}}
