These uncertain interference factors will cause the earned value analysis results are quite different from or even contrary to the actual situation, so there will not be enough impartial data to help managers to control project. To this end, this paper analyzes how the price fluctuations, process adjustment and the abnormal construction period will affect the construction schedule and cost effect respectively, and further studies the corresponding methods of earned value correction. Based on case analysis, this paper studies the comprehensive correction method of earned value when cost unit price changes, working procedure is adjusted and construction period fluctuates in an abnormal manner. The method improves the theory of earned value and provides reference for engineering practices on project management.<\/jats:p>","DOI":"10.3233\/jcm215570","type":"journal-article","created":{"date-parts":[[2021,10,26]],"date-time":"2021-10-26T12:14:18Z","timestamp":1635250458000},"page":"161-174","source":"Crossref","is-referenced-by-count":0,"title":["Engineering project control of comprehensive unit price fluctuation-time limit fluctuation-process adjustment"],"prefix":"10.66113","volume":"22","author":[{"given":"Xiangtian","family":"Nie","sequence":"first","affiliation":[{"name":"School of Water Conservancy, North China University of Water Resources and Electric Power, Zhengzhou, Henan, China"},{"name":"Collaborative Innovation Center of Water Resources Efficient Utilization and Support Engineering, Zhengzhou, Henan, China"},{"name":"Henan Key Laboratory of Water Environment Simulation and Treatment, Zhengzhou, Henan, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jianyou","family":"Shi","sequence":"additional","affiliation":[{"name":"School of Water Conservancy, North China University of Water Resources and Electric Power, Zhengzhou, Henan, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bo","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Water Conservancy, North China University of Water Resources and Electric Power, Zhengzhou, Henan, China"},{"name":"Collaborative Innovation Center of Water Resources Efficient Utilization and Support Engineering, Zhengzhou, Henan, China"},{"name":"Henan Key Laboratory of Water Environment Simulation and Treatment, Zhengzhou, Henan, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhirui","family":"Cui","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, North China University of Water Resources and Electric Power, Zhengzhou, Henan, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"55691","reference":[{"issue":"1","key":"10.3233\/JCM215570_ref1","doi-asserted-by":"crossref","first-page":"92","DOI":"10.1108\/14725960510808419","article-title":"Assessing the performance of construction projects: Implementing eared value management at the General Services Administration","volume":"3","author":"Alvarado","year":"2005","journal-title":"Journal of Facilities Management"},{"issue":"1","key":"10.3233\/JCM215570_ref2","doi-asserted-by":"crossref","first-page":"419","DOI":"10.1007\/s00170-009-2406-z","article-title":"Designing a control mechanism using earned value analysis: An application to production environment","volume":"49","author":"Bagherpour","year":"2010","journal-title":"International Journal of Advanced Manufacturing Technology"},{"issue":"5","key":"10.3233\/JCM215570_ref3","first-page":"75","article-title":"Dynamic cost control of construction project based on modern control theory","volume":"39","author":"Kang","year":"2013","journal-title":"Hydropower Generation"},{"key":"10.3233\/JCM215570_ref6","doi-asserted-by":"crossref","first-page":"400","DOI":"10.1016\/j.ijproman.2008.02.009","article-title":"Prediction of project outcome \u2013 The application of statistical methods to earned value management and earned schedule performance indexes","volume":"27","author":"Lipke","year":"2009","journal-title":"International Journal of Project Management"},{"issue":"8","key":"10.3233\/JCM215570_ref7","doi-asserted-by":"crossref","first-page":"834","DOI":"10.1061\/(ASCE)CO.1943-7862.0000192","article-title":"Probabilistic forecasting of project duration using Kalman filter and the earned value method","volume":"136","author":"Byung-Cheol","year":"2010","journal-title":"Journal of Construction Engineering and Management"},{"issue":"4","key":"10.3233\/JCM215570_ref8","first-page":"223","article-title":"Management thinking in the earned value method system and the last planner system","volume":"26","author":"Yong-Woo","year":"2010","journal-title":"Journal of Management in Engineering"},{"issue":"6","key":"10.3233\/JCM215570_ref9","doi-asserted-by":"crossref","first-page":"1019","DOI":"10.1016\/j.ijproman.2013.11.002","article-title":"EDM: Earned Duration Management, a new approach to schedule performance management and measurement","volume":"32","author":"Khamooshi","year":"2013","journal-title":"International Journal of Project Management"},{"key":"10.3233\/JCM215570_ref10","unstructured":"K.
