ABSTRACT
The method of numeric simulation and its tools (numeric simulators) are preferred and used-basically, for the research of dynamic and complex cyber systems, for which the utilization of other methods shows-at least one of the following particularities:
– it is impossible to be built or to be used, – it is very expensive, – it is uncertain (does not guarantee that you can
find or you can reach the expected results), – it is risky for the researcher and/or for the
environment, – it is long lasting (the time required until you get
the expected results exceed the moment of interest and it’s utility).
