Simulation Modeling

The next generation in CSSD design tools

To design a space, you need to understand the goal of the space. There are many inputs to a CSSD design. These should be well defined before you start.  If this is not done, you may have a space perfectly suited to another task. There are many tools available today to assist CSSD design teams but, the single tool that can have the greatest impact on the outcome of the space is Simulation.


What is Simulation? And, why bother?

Most CSSDs are planned and sized based on a deterministic calculator. These calculators are usually built in Excel. They are beautifully equipped to predict results on systems that have process time elements that can be predicted exactly. This works well for repeatable processes like a validated wash cycle or a sterilization cycle.  It turns out these types of calculators are not good at predicting CSSD total turnover / performance as shown above.
