How does SLX relate to GPSS/H?
GPSS/H is a very powerful simulation tool. It has a distinguished 20-year track record, and it has been used for a vast array of applications. We anticipate that it will be used for many more. While SLX is not a replacement for GPSS/H, it contains a lot of its spirit. For example, SLX’s “zero tolerance” policy for errors was derived from a similar policy in GPSS/H. In SLX we tried to build on the strengths of GPSS/H, eliminate cumbersome or rarely used features, combine related features into more general features, and package everything in an improved modeling environment. If you know and love GPSS/H, with a bit of gear-shifting, you can transfer your knowledge to SLX. We have implemented a subset of GPSS/H in SLX, so the familiar SEIZE, RELEASE, ENTER, LEAVE, QUEUE, DEPART, ADVANCE, and TERMINATE (among others) are available in SLX. GPSS/H’s GENERATE has been recast as SLX’s “arrivals” statement. Back to top.
