Unit 14: Simulation Languages (II)

to build on the strengths of GPSS/H, eliminate cumbersome or rarely used features, combine Notes
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.

SIMPLE++

SimpSim is a simulator/assembler for the machine language as proposed in “Computer Science:
An Overview” by J. Glenn Brookshear.
It features the following:
1. Windows 95/98/NT/XP/Vista, no installation required
2. Simulator with run, step and break functions
3. Built-in assembler editor with syntax highlighting
4. Built-in assembler
5. Loading and saving of files (assembler and machine coded (byte code))

6. Built-in assembler examples
7. Context sensitive helppages about virtually all items
8. Extra www infopage (this can be set by the teacher of a particular course to point to a page,
used for that course, with the latest information, hints and so on)

9. Disassembler/trace window for stepping
10. Output window to output text from a machine language program (see examples)
11. No password or registration needed, so everyone can use it

SIMUL8

SIMUL8 simulation software is a creation of the SIMUL8 Corporation used for simulating
systems that involve processing of discrete entities at discrete times. This program is a tool for
planning, design, optimization and reengineering of real production, manufacturing, logistic
or service provision systems. SIMUL8 allows its user to create a computer model, which takes
into account real life constraints, capacities, failure rates, shift patterns, and other factors affecting
the total performance and efficiency of production. Through this model it is possible to test real
scenarios in a virtual environment, for example simulate planned function and load of the
system, change parameters affecting system performance, carry out extreme-load tests, verify
by experiments the proposed solutions and select the optimal solution. A common feature of
problems solved in SIMUL8 is that they are concerned with cost, time and inventory.

SIMUL8 uses dynamic discrete simulation, which makes it possible to provide unambiguous
and concrete results and proofs - information on how the designed or optimized production
system will actually function. The outputs of SIMUL8 simulation are “hard data”, values and
statistics of performance parameters and metrics of the production system.
