Since the primary aim of simulation is to generate a set of pseudo-random numbers, it has a huge part to play in the security aspects of Defense system, as well as certain cryptographic projects. In such a scenario, a single method is not enough for getting the correct values of simulation.

Hence, there are multiple methods that are available to ensure that a correct judgment be made and here are some of the methods that are to be taken into consideration while dealing with a topic as this.

**Various methods associated with simulation techniques:**

**Monte Carlo Method:**

In this simulation system, there is an exploration of sensitivity of a complex system that is done by making correct usage of certain set parameters that are kept within the statistical bindings. The specialty that is found in these systems rests in the fact that they can include within itself a set of physical, mathematical and financial models that are simulated in a specific loop, with a number of uncertainties associated with that loop.

Invented by Stanislaw Ulam, this was first based on the random and chance outcomes that are based on modeling technique. From the time of its inception, it is being used for checking out the impact of risks and financial uncertainties in case of project management, associated costs and forecasting models.

In this case, random numbers from 0 to 1 can be taken while random observations can be made from any probability distribution that has been desired.

**Method****of Rejection:**

This is another method that is usedin getting random numbers. Based on the accept-reject algorithm format, this is a part of Monte Carlo mode.

**Inversion Method:**

This is another mode that is used by most of the concerned authorities. In this case, it so happens that generalized inversedis used as a basis for generating the range of pseudo-random numbers. These numbers are further taken as realizations in case of random variables that is distributed in a monotony, in an arbitrary manner and with a non-decreasing aspect and a right-continuous factor.

The best aspects of this method are that it helps in getting a faster algorithm that is sued for further generation of pseudo-random numbers. Also, it happens that the concept of trigonometric function is not applied in this case, and therefore an easy set of numbers can be found.

In most cases, these methods are being used for getting perfect data on simulation.
