History
of the
Fabric Simulator – SIMFLEX 1969
The
roots of SIMFLEX are found in the topics of the
1960-ieth - activities with
philosophical and epistemological basics.
- advancing development of
Computer
engineering
- research tasks of mechanical
engineering at the Institute for technical automation (IPA) under the
guidance of Prof. Dr.-Ing. W. Simon at TU-Berlin.

The leaders
in this area of
simulation were Geoffrey Gordon (GPSS), Pritsker/Kiviat (GASP,
SIMSCRIPT) in USA
and
Birtwistle/Dahl/Myhrhaug/
Nygaard (SIMULA) in Norway.
In Germany
the concept of Simulation was spread among the society for the purpose
of Operation
Research through the seminars from Professor Schneeweiss.
1972
At the IPA
in Berlin,
Reinhard and
Kamp developed a simulation tool for planning and control of flexible
Production Systems. The first models were implemented in FORTRAN and
GASP
respectively and the software package were implemented in FORTRAN.
Simulation
and real time control were already seen as a unit and was converted
into
prototypic applications for laboratories.
DFG
promoted the
work as Special
Research 57, “Production techniques and Automation”. Network

1977
SIMFLEX is probably the
first graphic-interactive factory simulator available for the public.
SIMFLEX is
implemented as object oriented in SIMULA. The assigned
Computer, PDP10,
had a value of around 1,5 millions DM. The
animation is implemented in FORTRAN on PDP15. The 2 computers were
coupled by
serial interface. Animation
seems
to be unnecessary for Science and Technology but it is the best for
„Management“. The term „Mäusekino“ ( Mouse Cinema) is coined.
1980
Production System is one of
the fields in the Department of
Mechanical
Engineering, University of kassel. In colloboration with PSI,
Berlin,
the factory Simulator was
implemented in PASCAL on the computer of Norsk Data and VAX. It
was
released as SIMFLEX/2 in Hannover exhibition in 1982.

1985
A real time
interface
for
SIMFLEX/2 to control electromechanical model plants of the enterprise
came into
operation. This was used as secondary control for computer networks in
1987 1991
SIMFLEX/2 and CAD
(AutoCad/MicroStation) were integrated. The Model draft is done in CAD.
The
layout of the client is taken over the DXF interface.
1992 SIMFLEX/2
is used as a
control station in Volkswagen AG, Central Training Center.
More than 6 Siemens-SPS plants were controlled. The development of a
user
langauge for designing logical process is sealed off. This represents
the rapid
development in the flexibilty of simulation studies.
1994 The
re-implementation was
started in C++. The screen, conversation window and graphics were built
on Tcl/Tk
and it becomes platform independent.
1997 The
first prototype of
SIMFLEX/3 is presented. Special features are:
- Object-Oriented
as in 1977
- CAD
Interface
- C++
User Interface
for logistics
- BDE interface for usual
analysis programs
- Real time interface for
electromechanical
plants
- On-line animation,
alternatively in 2D or 3D
- Executable under LINUX and
Windows

The HLA
interface is
implemented. SIMFLEX/3D can be coupled with one another and with other
simulators. Thus SIMFLEX/3D can be used in a distributed simulation
environment.
