Gordon's GPSS Examples

Below are the examples from Gordon's book, slightly modernized (mostly by using symbolic names wherever possible to increase readability).

The following file-types can be found below:

• modelname_GPSS_mdl.eps : an image in Encapsulated Postscript of a GPSS block diagram (in the meta-modelling tool AToM³).
• modelname_GPSS_mdl.pdf : an image in PDF format of a GPSS block diagram (in the meta-modelling tool AToM³).
• modelname_GPSS_world.gps : a binary model file for the GPSS World modelling and simulation tool (for the Windows platform). You can download GPSS World student edition from www.minutemansoftware.com. The software has a builtin help. The online reference manual is at www.minutemansoftware.com/reference/reference_manual.htm. A note to Linux users: GPSS World can be run under Linux using the free implementation of Windows for Unix wine.
• modelname_GPSS_world.gps.txt : a readable (text) version of the GPSS model simulated in GPSS World.
• modelname_GPSS_world.simres.txt : a readable (text) version of the results of a simulation run of modelname_GPSS_world.gps in GPSS World.

Designing GPSS models visually in AToM3

Drawing of models may be done with AToM³. A version of AToM³ with GPSS support is here [AToM3-GPSS-2.2.tgz] [AToM3-GPSS-2.2.zip]. In the GPSS/models directory, the models are call modelname_GPSS_mdl.py. Launch the ATOM3.py application to get started.

There is support (limited, use with caution) for .gps generation from a block diagram specification in AToM³. As GPSS World uses a binary format for GPSS models, you need to paste the .gps text file into a New Model window in GPSS World.
