There are several ways to schedule projects including the Critical Path Method CPM Received in revised format April and Program Evaluation and Review Technique PERT . Due to problems in estimating dura- 1 2018 tions of activities these methods cannot accurately and completely model actual projects. The Accepted April 3 2018 Available online use of fuzzy theory is a basic way to improve scheduling and deal with such problems. Fuzzy April 4 2018 theory approximates project scheduling models to reality by taking into account uncertainties in Keywords decision parameters and expert experience and mental models. This paper provides a step-by- Project management step approach for accurate estimation of time and cost of projects using the Project Evaluation Time estimation and Review Technique PERT and expert views as fuzzy numbers. The proposed method in- Cost estimation cluded several steps. In the first step the necessary information for project time and cost is PERT estimated using the Critical Path .
