Earned value project management (EVPM) is an effective tool for managing project performance that has 32 criteria. These criteria are the all the requirements of a proper project management system and present in the following five main groups. Organizing, Planning, Scheduling and Budgeting, Accounting and control and data analysis. In the second group, criteria such as project performance is exited that measure by earned value management methodoligy. However, most studies on extensions and applications of EVPM concentrate on improving final cost and duration estimates rather than improving upon the use of planned value (PV) to predict earned value (EV) and actual cost value (AC). This study proposes an integrated model by incorporation ISM model and EVM methodology to identify factors that effect on the EVM system in counstruction projects. Primarily, the factor affecting on EVM are identified and then using questionnaire to ranking them, then most important criteria on the divison of the main factors of time, cost, risk and quality is determined. Finally Using the interpretive structural model (ISM) to examine the relationship between the factors are discussed. Research result indicate three factors: changes in planning phase, disruption in finnacial phase and inadequate desing are the most important effective factors on earned value manamgement that infulence on the other factors. The project manager must consider all elements are existed in ISM model, especially these three factors to finally achieve project goals in implementaion time.
