We can make changes without fear of making mistakes, as this tool has multiple uses, such as designing production lines, planning manufacturing, managing material inventories, and scheduling automatic machines. It is especially useful when information is scarce and processes are complex.

There are several types of simulation, such as discrete event simulation, which is based on the behavior of things, and Monte Carlo simulation, which allows testing many possibilities, among others.

Benefits of Simulation in Companies

Below is a list of the general benefits of simulation in companies:

  • Simulation helps make informed decisions before it’s too late, allowing you to anticipate changes and improvements.
  • Using simulations in companies is key to saving time and money, improving customer service, and making internal work processes more efficient.
  • It is important for better thinking about how things are done, innovating in business, and planning for the future. It helps understand how workers, processes, and technology relate to each other and make informed decisions for the company’s future.
  • Modeling different scenarios with simulation allows for more accurate decision-making, applicable not only in industry but also in areas such as logistics, inventory management, and customer service.
  • Simulation makes it possible to “play” with business models on a computer, helping us better understand how they work and make accurate decisions. Without simulation, important processes like the supply chain would be difficult to analyze in-depth. It is crucial to clearly define the processes we want to simulate and understand how they relate to make the simulation more effective in improving our operations.
