Program Evaluation and Review Technique (PERT) is the most widely used network modeling method used to track the planning activities required to complete large-scale projects. This technique has the potential to reduce the time and costs required to complete a project. Unlike classical PERT, fuzzy sets theory allows both the uncertain demand and the subjective judgment of the decision maker. The main objective of this article is the presentation of theoretical aspects of the two methods of project network analysis. Uncertainity is a major problem in Operations Research, and network planning with uncertain activity durations is typically an area where stochastic and fuzzy concepts are fundamentals.
