After looking into different industries, we can see that there is obviously a massive need for simulation where the aim is to solve real-world problems from how a ticketing system should work in a hospital to what to do when a natural disaster strikes. Simulation allows us to forecast potential problems without having to first live through those problems.
Different uses of simulation in the industry are as follows:
Manufacturing: The following are the uses under manufacturing:
To show how labor management will work, such as worker efficiency, and how rotas and various other factors will affect production
To show what happens when a component fails on a production line
CrowdManagement: The following are the uses under crowd management:
To show the length of queues at theme parks and how that will affect business
To show how people will get themselves seated at an event in a stadium
Airports: The following are the uses for airports:
Show the effects of flight delays on air-traffic control
Show how many bags can be processed at any one time on a baggage handling system, and what happens when it fails
Weather Forecasting: The following are the uses under weather forecasting:
To predict forthcoming weather
To predict the effect of climate change on the weather
That's just to outline a few, but hopefully you can see how and where simulation is useful.
Simulating your network will allow you to test the network against myriads of network attacks, and test all the constraints of the network without damaging it in real life.
