Keywords:project scheduling, network planning, , network diagram, CPM method, CCM method, PERT method
Project scheduling methodology has been studied widely, and various tools have been developed for accurate scheduling. In this paper an analysis of the techniques and methods for project planning and re ‐ planning in construction is presented. A comparison was made among CPM and CCM methods, PERT and other probabilistic methods and necessary conditions to apply each of these techniques were determined. Traditional network scheduling techniques, CPM and PERT have been widely applied for the past decades. However, schedule delays often occur in many construction projects. A multitude of reasons affect the success of a project and unrealistic schedules is often the main reason for project failure.
