Abstract

GPSS (General Purpose Simulation System) is a simulation programming language whose use greatly eases the task of building computer models for discrete-event simulations. GPSS is easier to learn than the statement-oriented simulation languages such as GASP [8] and SIMSCRIPT [9]. It is less flexible than the statement oriented languages, however, even though it can be interfaced with FORTRAN subroutines (for examples, see [2] and [6]), and PL/1 procedures. A thorough-going comparison of GPSS and SIMSCRIPT has been presented in [5]. The GPSS tutorial will present a basic set of GPSS “building blocks,” then illustrate their use in the context of a simple one-line, one-server queuing system.
