SystemModel—Theproposedmodelisdescribed.There
will invariably be assumptions made. State the model
assumptions clearly. Do the assumptions make sense?
Sometimes it will be necessary to introduce assumptions
to make the problem mathematically tractable, but they
should at least reflect some real-world situations. Thus
while the proposed assumptions may not hold in general,
there should at least be some instances where they will
hold and hence the model and conclusions drawn will
apply. Use figures to help explain the model.

6) Numerical results—Based on the model, numerical re-
sults will be generated. These results should be presented
in such a way as to facilitate the readers’ understanding.
Usually, they will be presented in the form of figures or
tables. The parameter values chosen should make sense.
They should preferably be taken from systems in the
real world. If that is not possible, they may correspond
to those values for which published results are available
so that one can compare these results with existing ones.
All the results should be interpreted. Try to explain why
the curves look the way they do. Is it because of the
assumptions, or because the system behaves that way?
In most cases, a simulation model is required to validate
the system model with the assumptions. In that case,
it is important to not only show the average values of
the simulation results, but also confidence intervals. A
number of books on modeling techniques will show how
confidence intervals may be obtained. In addition, it is
very important to explain what is being simulated. I
once attended a thesis defense in which the candidate
claimed that his analytical results matched the simulation
results perfectly. I then found that he had basically
simulated the analytical model, using the same assump-
tions! Details on the simulation time, the computer,
and the language used in the simulation should also be
