Abstract: This paper presents the development and use of an interactive, microcomputer-based model for project planning and scheduling. The model is general enough to handle both deterministic (CPM-based) and probabilistic (PERT-based) networks. In the deterministic mode, the model (CPMPERT) performs routine critical path analysis, as well as a time-cost optimization of the network for linear time-cost activity functions. In the probabilistic mode, CPMPERT essentially performs a Monte Carlo simulation of the network, with activity durations taken as random deviates from either the beta, triangular or normal distributions. Up to 50 network simulations may be performed in this case. CPMPERT runs on an IBM PC or compatible, requires 64k RAM and one disk drive. Options include additional memory, a parallel printer for hard copying of the output and an extra disk drive to store data files separately from the program disk.
