Comparative Study on Pert and Simulation Modeling

Adithyan. R, Ambedkar. S, Anbarasan. A

PERT is one of the widely used management techniques for analyzing commercial and industrial projects from a managerial point of view. It analyses processes in the form of networks and gives an estimate of the overall process completion time. It also identifies the processes that cause the greatest impact to the overall process. These processes are called critical activities and the path they follow is called the critical path. In real time systems the uncertainties associated with the processes are not known before hand and as a consequence meeting the scheduled delivery date becomes difficult. This is because the process time of a critical path is crucial for the completion of the process and if the uncertainties associated with the critical process is not known in advance then the probability of not meeting the delivery date increases. In addition to this experimenting with the actual system is not cost effective. A solution to all the problems associated with analysing the actual system is to simulate the PERT network.
