3. Main terms

Model is a material or abstract object which
substitutes an original object in investigation
(studying) process, saving some important and
typical
characteristics
and
features
for
investigation
Modelling is a process where one object
(original) substitutes another one (model) and
fixes original object characteristics by means of
model characteristics studying
Замятина О.М.

4. What models can be created for?

For understanding:
1. What is the object structure?
2. What are main object properties and
characteristics?
3. What are object evolution laws and
object interaction with environment?
Замятина О.М.

5. What models can be created for?

For
object
management
and
controlling at the framework of
certain goals and conditions
For forecasting of direct and indirect
consequences of different influences
on the object
Замятина О.М.

6. The model allows to

manage the original object by means
of changing and approving different
control methods over the model;
avoid and decrease financial costs;
carry out experiments with the model
in case when a real object is
unavailable.

8. Main terms

Adequacy is a degree of conformity of
modelling to original object, which we obtained
in the process of model investigation, testing
tasks and experiments
Adequate model is the model with certain
approximation degree which reflects the
process of original object functioning in the
real conditions
