The PERT chart is a planning and control technique that utilizes a network for scheduling a project's events (activities) in the proper sequence or in a logical order to accomplish a predetermined project. The PERT chart shows the interrelationship between two project events from which a critical path is developed for the project. The critical path is the path between the first activity date and the last activity date to complete the project. The PERT chart allows your project manager to make a decision on minor events and to show how these minor modifications affect the next event or the overall project.

Some advantages of PERT are: (1) putting the tasks, sequences, and times into the network shows potential problems while the project is still in the planning stage, (2) it shows which tasks should and should not be expedited, (3) it sets up progress checkpoints, and (4) it tends to be self-fulfilling since people work toward known schedules. Disadvantages are: (1) PERT takes time and effort to set up and (especially) to maintain and (2) the times may be too long. That is, since there is a PERT analysis, the project may take longer. This is because people work to the schedule.

For many years the most common use of the beta distribution has been in the program evaluation and review technique (PERT). PERT is a method of project scheduling. It is similar to critical path analysis (CPA), which is often used in the construction industry for project planning. The crucial difference is that PERT explicitly includes risk measures of the likely time that each of the activities in a project might take. These times for completion are usually modelled on the assumption that they take a beta distribution. The beta can of course be used to model other random variables.

Project Evaluation and Review Technique (PERT) is vastly utilized by project managers as a probabilistic model of the Critical Path Method (CPM). The PERT technique is an essential tool for the estimation of project completion, besides it is also workable and cost-effective for management of projects. PERT has gained this wide interest from management practitioners due to its flexibility and simplicity in dealing with stochastic activity networks (SANs). A SAN is determined by where N is the set of nodes (), is a set of arcs (), is a distribution function (DF), and Tr is a random variable (RV) which depicts the duration of the arc In SANs, usually the problems of determination the largest and shortest paths are encountered. The first problem, the determination of the largest path, concerns with finding the distribution of while the second problem, the determination of the shortest path, pertains to finding the distribution of where the RVs represent the completion times of the project activities.
Prediction, investigation, and assessment of novel tidal–solar hybrid renewable energy system in India by different techniques

Before the beginning of any venture, it is critical that the undertaking group has to consider to what extent it would take to execute the task. This is basic since it ensures that the concept of top event is necessary to knows precisely to what extent it would take to get the task finished, thus can consider that when choosing a financial plan for the undertaking. The Programme Evaluation and Review Technique (PERT) is a framework that guides the booking and coordination of undertakings amid a venture. Perky is an undertaking administration system, used to oversee questionable exercises of a venture; however, CPM is utilised in this paper in light of the fact that CPM is a measurement procedure of task administration that oversees all around characterised exercises of a venture. Based on predictable activities, CPM develops a deterministic model to control costs and time. Table 3 shows the activity performed during the completion of project and the number is assigned to each activity that is further dependent on the other and duration of completion of each activity in the month also presented in the given table. Figures 12 and 13 represent assigned activity name and duration of activity after that early and late start and finish time each activity. Figures 14 and 15 show the critical path which is represented by path 1-2-8-13-17 and duration of completed work is 75 months or approximate 6 years. In six years duration included preliminary stage to supply the electricity to the given load.
Interval type-2 fuzzy program evaluation and review technique for project management in shipbuilding

PERT is a statistical method used in project management which is designed to analyse, represent, plan, and control tasks. In general, the PERT method is summarised by the expected time calculation, forward pass calculation, backward pass calculation, and slack time calculation.
