Answer: Ability to derive optimal solutions
Explanation:
One of the main disadvantages of simulation is ability to derive optimal solutions. As, the solution does not required to have a closed form and procedure does not require any weighting and the hard constraint. Stimulation outcome are not optimal to induced specific response because of the lack of quantitative models.
