PERT network chart for a seven-month project with five milestones (10 through 50) and six activities (A through F).. The program evaluation and review technique (PERT) is a statistical tool used in project management, which was designed to analyze and represent the tasks involved in completing a given project.
Although the activity-on-arrow diagram (PERT chart) is still used in a few places, it has generally been superseded by the activity-on-node diagram, where each activity is shown as a box or node and the arrows represent the logical relationships going from predecessor to successor as shown here in the "Activity-on-node diagram".
The main limitations of PERT or CPM that might be addressed by GERT are: there are no alternative paths - all activities have to be performed; there are no loops - it is not possible to repeat activity, next similar activity has to be added; there are no decisions in the diagram - no and, or, xor options which help to choose proper path
PERT network chart for a seven-month project with five milestones (10 through 50) and six activities (A through F). X-Pert supports the full cycle of project management – through multi-level work breakdown structure creation, transition to multiple projects using critical path diagrams and Gantt chart presentation.
In probability and statistics, the PERT distributions are a family of continuous probability distributions defined by the minimum (a), most likely (b) and maximum (c) values that a variable can take. It is a transformation of the four-parameter beta distribution with an additional assumption that its expected value is
