Simulation and Modelling

Notes 14.2 Expression based Languages

Expression oriented continuous languages are based on writing expressions (equations) that
represent the mathematical model. So the system simulated must be expressed by a set of
equations. Then the user adds statements and/or directives that control the simulation. Some
languages enable both block and expression based ways of system definition. Simulation control
means selection of: the integration method (because some languages offer more), the integration
step, the variables (outputs of blocks) that should be observed, the intervals for collecting data
for printing and/or plotting, scaling of outputs (that may be also done automatically).

Notes Duration of the simulation runs, number of repetitions and the way certain values
are changed in them.

AutoMod

AutoMod simulation software meets the needs of equally the casual, first-time user and the full-
time simulation model builder. You can easily and accurately simulate systems of any size or
level of detail, from manual operations to fully automated facilities. AutoMod is a world-
leading software for simulation of production and logistics systems. The software is designed
for detailed analysis of operations and flows. Although mainly used in manufacturing and
material handling systems analysis, AutoMod’s flexible architecture allows it to be used in a
wide range of application areas, from airports to semiconductor industry.

Application/ Benefit

User-friendly, detailed 3D-animation, capable simulation and numerous analysis options are
the keywords of AutoMod.
AutoMod offers a variety of probable applications due to its very efficient simulation core.
These extend from modelling manufacturing processes through warehouse simulation and
supply chain simulations to online link-up/emulation.
With AutoMod the emphasis is not only on processing power but also on the ever more important
visualisation right through to virtual reality. Thus communication between management,
production and staff can be improved significantly. Here modelling the simulation models is
carried out interactively with the aid of graphic support. Complex controls and processes can be
mapped with the aid of a simple simulation programming language.

Structure / Modules

In order to be able to adapt the software to the respective intended purpose, it has a modular
structure. The basic system includes Process System, Simulator, Dtrace, ACE, IGES and SDX
import option. The following modules are available as extension modules:

1. AS/ RS (warehouse technology)
2. Conveyor (conveyor technology)
3. Kinematics (robots)
