ABSTRACT
-
FORT~
. ·CYSDEM' is a new
based simulation language.
It is used to simulate business informlltion systems. The
'm.ain. feature ,of CYSDEH is that it concentrates' Ol\...delays
/
and
distortions,~o which
information in actual systems is
-
-
subjected to.Therefore,CYSDEM allows a more realist~ representation' of the movement of data WithinfinfOrmati,,on
systeni•.
,
,
CYSDEM is base,d on a schematic repres'entation,of
the~ormatio~ system
under consideration, called the
I
~RSTRUCTURE. The CYBERSTRU~URE is constructed by the
j(
,
{~er.
It helps the user in identifying relevant information.
q
lan~uage ,requires
Any new computer
careful veri-
fication and complete documentation. This report contains
J
an introduction to simulation apd a user's guide. p'artial
,.
verification of CYSDEM was performed using q, productionJ
.;/
'
distribution system from Forre~ter's -Industrial Dynamics-.
, The example is explained and the results are included in
this report,;
