Modeling and simulation of projects with Petri nets; Report

December 1, 2008 from Project, Program and Portfolio Management


  INTRODUCTION   Project management is a complex task. Its functions like planning,scheduling and control are difficult since constraints like resource,    time and cost to be managed difficult to deal with. To manage theseconstraints in practice, the modes of operating project are changed often to meet the time and cost tradeoffs. Therefore, the effective management of the project is critical. The most popular methods for project planning and management are based on a network diagram such as Program Evaluation and Review Technique (PERT) and the Critical Path Method (CPM). Although these have been successful in off-line planning    and scheduling, it is difficult to dynamically monitor and control the progress of the project and to model resource constraints becauseinformation is loosely coupled. The availability of improved tools such as decision CPM (DCPM), Graphical Evaluation and Review Technique(GERT) and Venture Evaluation and Review Technique (VERT) have not satisfied the requirements.
