“…The Duration Performance Index (DPI) is a metric designed to measure how close a project is to its scheduled completion date. However, it is important to note that the DPI may produce inaccurate results, both in terms of overestimating and underestimating progress, as a result of the complex influence of parallel activities [27]. The findings of Wendell et al [27] indicated that many earned value measures possess similar limitations, leading to further research into alternative methodologies.…”

Project management is the process of planning, organising, leading, monitoring, controlling, and closing a project. Earned Value Management (EVM) is the conventional method for monitoring and controlling construction projects. Schedule monitoring with EVM has a lower impact since it measures in budgetary terms. Earned Duration Method (EDM) was presented, which decouples schedule and cost aspects. The parameters in EDM monitors the health of the project schedule and gives the estimated completion date. EDM results are indeterministic, so the estimators require expertise in order to comprehend them. For this purpose, the present study proposes a new methodology entitled “Grey Earned Duration Management (GEDM)” by associating EDM and grey theory. From GEDM, estimators can get a clear idea about the degree of control measures to consider based on the project progress at a particular point in time. GEDM can precisely forecast the upper bound and lower bound of the estimated duration at completion for every tracking point. GEDM significantly enhances the results of EDM by providing a range of the estimated parameter. This paper also presents a case study to distinguish EDM and GEDM.
