The objective of this study was to compare two commonly used computer simulation languages: GPSS and FORTRAN. The comparison was made by simulating an identical system in both languages. The comparison criteria used to evaluate the languages were as follows: ability to represent system, simulation time, ability to represent stochastic phenomena, programming time, computer running time, monitoring and debugging, storage requirements, data initialization and starting conditions, replication data collection and display. The results from this study indicated that a system may be modeled four to five times faster using GPSS as compared to FORTRAN. The modeled system was simpler to conceptualize in GPSS, and the model required reduced programming, debugging and monitoring time compared to the FORTRAN model.
