The document is a simulation course exam for a master's program consisting of 7 questions about system dynamics modeling. The exam is 3 hours long and administered by Dr. Mohamed Saleh. The questions cover strategic level modeling, comparing system dynamics to other approaches for the T21 model, an alternative modeling approach, theoretical foundations and validation of the T21 model, limitations and enhancements of the T21 model, and the concept of synthetic data and its application in the energy sector.

RE-Exam
Instructor: Dr. Mohamed Saleh
Duration: 3 hours
Question 1:
A) Explain, in details, the term “strategic level” modeling.
B) Give three examples of the use of system dynamics in “strategic level” modeling.
Explain briefly these examples.
Question 2:
Explain why the developers of the T21 model used the system dynamics (SD) approach.
Hint: Compare and contrast SD with other approaches.
Question 3:
System dynamics is useful in many modeling circumstances, but not all. Describe a
realistic problem in which system dynamics would not be the best approach to solve the
problem. That is, describe a problem in which an alternative modeling approach has
important advantages. Do not select a problem which cannot be solved or modeling is
impossible.
Question 4:
Explain, in details, the major theoretical foundations of the T21 model.
Question 5:
Explain, in details, how you can validate the T21 model.
Question 6:
From your point of view, what are the main limitations of the T21 model?
How can you enhance the T21 model?
Question 7:
In his lecture, Prof. Paul Davidsen explained the “synthetic data” concept, and applied it
in the energy sector. Explain, in details, the concept and its case application.
