Simulation of Automated Warehouse System: Using CPM and PERT Method

K.M.Salah Uddin, Afroza Akter Jinia


PERT and CPM are two most widely used method for project management. PERT use probabilistic time estimation for project completion, on the other hand CPM employs deterministic time for crashing project. Specific deadline can be achieved by crashing which is basically a time-cost trade-off. The traditional method of crashing only considers average activity times for the calculation of the critical path, ignoring the stochastic nature of activity time. Here a stochastic simulation is done to evaluate the PERT.  And frequencies of project completion time in different simulation length are presented. A linear program is developed for crashing the project to minimize the required cost while attaining a specified completion time.

Keywords: PERT, Stochastic simulation, Crashing, Project completion time (PCT), Simulation length (run)
