**3. Results**

In description of Monte Carlo simulation, this model can be easily calculated using the random value. A typical Monte Carlo simulation program can easily calculate the model verification by counting indefinitely, where each time they use different randomly selected evaluations.

As the result, the Monte Carlo simulation program is a very important program that was used also by Einstein's group in Manhattan Program for atomic bomb energy determination.

It is difficult to predict the real situation with absolute precision and accuracy which can be attributed to the different parameters that can impact the outcome of a course of action. The Monte Carlo Simulation can give all possible results for a new decision. It can thereby help us take improvements of a solution for a difficult situation under uncertainty. The probabilities of outcomes can be easily discussed by decision-makers.
