A New Fuzzy Approach for Project Time Assessment Under Uncertain Conditions

Abstract

Project control is a part of feedback system intended to find and rectify deviations from desired plan. Earned value management (EVM) and its extensions as project control approaches regard monetary values to assess the project schedule performance. For this reason., they sometimes provide inaccurate duration performance results. In this regard, earned duration management (EDM) which is an effective project time control method, is proposed. EDM is a cost value free technique in evaluating and estimating the project time performance. Since the uncertainty is inherent in projects' areas, it should be considered in the control and monitoring process. In this paper, a new triangular intuitionistic fuzzy earned duration model is presented to control the project time performance under uncertain conditions. Modified EDM indices and measures are introduced to evaluate the project time performance under uncertainty. Finally, a case study from the recent literature about construction project is given to show the model's applicability in real-life conditions.
