In , the E. The group had a UNIVAC I computer the third unit built at its disposal, and they decided to evaluate the potential of computers in scheduling construction work. Mathematicians worked out a general approach; they theorized that if the computer was fed information on the sequence of work and the length of each activity, it could generate a schedule of work.

Consequently, a project schedule should especially be considered as nothing more than a predictive model that can be used for resource efficiency calculations, time and cost risk analyses, project tracking and performance measurement, and so on.

The program or project 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. First developed by the United States Navy in , it is commonly used in conjunction with the critical path method CPM that was introduced in PERT is a method of analyzing the tasks involved in completing a given project, especially the time needed to complete each task, and to identify the minimum time needed to complete the total project. It incorporates uncertainty by making it possible to schedule a project while not knowing precisely the details and durations of all the activities. It is more of an event-oriented technique rather than start- and completion-oriented, and is used more in those projects where time is the major factor rather than cost. It is applied on very large-scale, one-time, complex, non-routine infrastructure and on Research and Development projects. PERT offers a management tool, which relies "on arrow and node diagrams of activities and events : arrows represent the activities or work necessary to reach the events or nodes that indicate each completed phase of the total project.

And now effective planning and programming necessities has made operational research an essential component of health care. What is PERT? PERT is a project management planning tool used to calculate the time it takes to complete a project in a realistic integratzia. PERT is majorly applied for scheduling, organization and integration of different tasks within a project. It provides the blueprint of project and is efficient technique for project evaluation.

We apologize for the inconvenience...

It considers various parameters of a project. These include money, material, manpower, time, and other resources. We have network planning methods for this. PERT was developed essentially to simplify the planning and scheduling of large and complex projects. It was developed for the U.

In the field of operation research, there are many interesting scientific theories which are also taught in several professional programmes in apparel production technology which may bring substantial benefit to users. In his new series of articles, Dr. Prabir Jana, Professor, National Institute of Fashion Technology, New Delhi explains some operation research tools, and how and where these tools can be used effectively. Some of the common problems faced in apparel manufacturing are: How to estimate the duration of any activity; How to estimate the order lead time; How to identify activities with zero tolerance that requires special attention to avoid delay in final delivery; How to identify and rationalize leave sanction of employees to ensure minimum impact on performance or even prioritizing purchase of items for bottleneck activities.

PERT and CPM: Comparison and its Differences

Program evaluation research technology PERT and the critical path method CPM have become widely recognized as valuable tools for the planning and scheduling of large projects. These methods provide a strong theoretical basis for the managers in planning, arranging progress, dealing with the impact of uncertain factors and controlling cost. When it is difficult to accurately estimate the time of some activities, Three estimation methods of PERT can calculate the approximate probability of completing the project within the required time too.
