Simulation and the YSI Philosophy !

Well, now imagine that you can see the consequences of that decision. Surely, you would think twice if the effects were not as expected. Life is uncertain and arbitrary, and although knowledge and self-experience are good companions, there are always thousands of factors beyond our control.

In contrast, production processes are more certain, more mathematical, more precise. They follow an established pattern of behavior, so we can imagine the changes, translate them into software and see the effects of our possible decision. This is Simulation.


Simulation is a prediction tool, it is imagining several possible futures and being able to choose the most convenient one to live it.


The simulation follows the WhatIf’ philosophy: What if I invest in a new machine? What if I add a worker on this line? What if? What if? What if? What if? What if? What if? What if? What if? What if? What if? What if?

This series of assumptions allows us to know in advance the behavior of a system in the face of certain changes, whether it is a process, a set of processes, a series of resources, etc. By measuring and comparing the results obtained, problems and inefficiencies in the system can be identified and eliminated, which otherwise could only be known once the ideas have been implemented, which would be a waste of time and money.

The most important thing in any simulation is the previous data collection. The first step of a Simulation Project is to correctly understand the behavior of a system to later model it.  At Scwuimac! we start these projects with an analysis of the system to know as accurately as possible the activities carried out in it, their relationships, resources, times in the development of activities, the frequency of those activities, constraints and objectives, etc. In addition, we correctly identify the process generators (specific and/or random generation).




The simulation of a system or process allows a quick and economical evaluation of its performance, anticipating its impact, values, and the change in costs that occur in each case. With the analysis of the different scenarios, the proposed improvements can be evaluated and chosen and the uncertainty of the results can be considerably reduced. In addition, it has the following advantages:

  • Cost, time and effort savings.
  • Minimal risk by working on software instead of physical reality.
  • Accurate conclusions for later implementation.
  • Increased productivity.
  • Increased customer satisfaction by improving the speed of production orders.


A few years ago, Simulation WAS a luxury available only to the wealthiest, or the bravest. Today, immersed in the era of technology, the offer of simulation software has multiplied and there are multiple options available to all organizations, with different costs and advantages. More and more entrepreneurs are becoming aware of the importance of the Ysi philosophy and the need to use simulation tools before taking action.

Since uncertainty will always exist in a process/service, we will call it ‘betting on almost certainty’.

The Scwuimac team, made up of experts in production processes and simulation, can help you.
