It should be about how you have conducted the Monte Carlo Simulation study, for example:

What type of system did you investigated?
Was it discrete or continuous?
What were the uncertain variables?
Why did you do it with Monte Carlo Simulation and not other types of simulation?
How many runs or replications you needed, how did you decide?
Will different runs give better results?
How would you know you have good results?
What about data analysis €“ what role do they play?
What about variance reduction? what does it mean?
Speed and accuracy?
Seed number?
