In order to show the five applications for system design and modeling that are used most often, examples should be provided. For further information on the importance of simulation and the practical applications it has, please refer to published scientific studies that have been examined by experts in the field. Note that you are not required to immediately come up with a solution to the problem.

How can simulation models most accurately reflect situations that do not cleanly fall into any one category?

Discuss through examples the five most common uses of systems design and simulation. For more information on the importance and practical uses of simulation, please consult peer-reviewed and published scientific publications. NB. You don't have to solve it in a single day.

When attempting to reproduce scenarios that cannot be pigeonholed cleanly into a single category, what are the best ways to make use of simulation models to achieve one's goals?

What is your suggested approach for utilising simulation models to replicate complex issues that do not conform to a singular category?

In each of the four approaches below, please detail the ways in which discrete event simulation contributes to the overall success of the procedure.
