Our premier simulation product,
GPSS World, is based on the seminal language of computer simulation,
GPSS, which stands for General Purpose Simulation System. This
language was developed primarily by Geoffrey Gordon at IBM around
1960, and has contributed important concepts to every commercial
discrete event Computer Simulation Language developed ever since.
GPSS World is a direct descendent of GPSS/PC, an early
implementation of GPSS for personal computers. Since it's
introduction in 1984, GPSS/PC and its successors have saved
thousands of users millions of dollars. GPSS World is the worthy
descendent of these early simulation environments.
GPSS World is designed to deliver
answers quickly and reliably, with the least effort, achieving the
highest reliability of results. Consistent with these objectives,
visualization of running simulations is highly stylized and a
default statistical treatment is built in. This approach means that
animations are "free" requiring no additional effort to produce, but
are not photo-realistic. GPSS World's forte is transparency, not
photo-realism. Third party animation systems are available which can
provide pictorial animations based on GPSS World simulations.
GPSS World was designed primarily to deliver quality answers while
maintaining a high level of transparency and controllability. Further, GPSS World facilitates the
statistical analysis required of any serious simulation project. In
summary, it is a self contained environment with everything from
built-in probability distributions to automatic experiment
generation, for screening as well as for optimization.
