Lab 4 – States, Properties, Simio Processes, Add-On Processes


In this lab we will revisit the Simio model of the Subway® restaurant that was developed in Lab 2 and use Simio Add-On Processes to extend our original model to include customer balking. We will also discuss an alternative method using add-on processes to implement type-dependent processing times. The videos will guide you through:

  1. Understanding how Simio processes work
  2. Implementing the balking logic using add-on processes
  3. Implementing type-dependent processing times on the oven using add-on processes
  4. Using State Assignments to change object states
  5. Defining “Responses” for the performance metrics
