The time\u2013cost trade-off (TCT) is known as a prevalent and efficient approach applied when the planned finish date of a project is not admitted by stakeholders, and consequently, the project duration must be decreased. This paper proposes a new mathematical model under fuzzy uncertainty to deal with the project cost\u2013risk\u2013quality trade-off problem (CRQT) under time constraints. Because of the unique nature of projects and their uncertain circumstances, applying crisp values for some project parameters does not seem appropriate. Hence, this paper employs fuzzy sets to resolve these weaknesses. In this study, two approaches are presented to handle proposed fuzzy multi-objective mathematical model. First, fuzzy credibility theory and then goal attainment method are used. Secondly, the model is solved by a fuzzy method based on expected interval and value and augmented \u025b-constraint method. A project from the literature review is adopted and solved by the presented methodology. The results demonstrate the accuracy and efficiency of the two proposed approaches for the introduced practical problem.<\/jats:p>","DOI":"10.3390\/a15070226","type":"journal-article","created":{"date-parts":[[2022,6,28]],"date-time":"2022-06-28T23:59:22Z","timestamp":1656460762000},"page":"226","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["A Mathematical Model and Two Fuzzy Approaches Based on Credibility and Expected Interval for Project Cost-Quality-Risk Trade-Off Problem in Time-Constrained Conditions"],"prefix":"10.3390","volume":"15","author":[{"given":"Mohammad Hossein","family":"Haghighi","sequence":"first","affiliation":[{"name":"Department of Industrial Engineering, Shahed University, Tehran 3319118651, Iran"}]},{"given":"Seyed Meysam","family":"Mousavi","sequence":"additional","affiliation":[{"name":"Department of Industrial Engineering, Shahed University, Tehran 3319118651, Iran"}]}],"member":"1968","published-online":{"date-parts":[[2022,6,28]]},"reference":[{"key":"ref_1","first-page":"363","article-title":"Resource constraint scheduling with a fractional shared resource","volume":"39","author":"Singh","year":"2011","journal-title":"Oper.
