Using simulation, one can exhaust all possible options for a problem and thus find the optimal solution, though it may take a little more computation time.
The only method to validate a simulation model of a non-existing system is to use the test of reasonableness.

Question

Quizplus · Accepted Answer

Simulation can explore many, but not necessarily all, possible options due to the vastness of the solution space in complex problems, and there are multiple methods to validate a simulation model, including expert review, comparison with other models, and historical data validation, not just the test of reasonableness.
