Earned value analysis is regarded as an analytical approach for hybridizing scope, schedule and resource along with measuring projects' performance and forecasting projects' outcome. This research presents a novel uncertainty approach about earned value indices in the context of interval type-2 fuzzy sets to enhance the applicability of these indices under real-life circumstances. The proposed model is presented for project managers to help manage project costs via a flexible and intelligent approach. The advantage of this model based on new extension of fuzzy sets theory (i.e., type-2 fuzzy sets) is the accuracy in the modeling of projects uncertainties. Finally, a practical example illustrates how the proposed interval type-2 fuzzy model can be implemented within the earned value analysis in projects under uncertainty.
