Lab 8 – User-defined Statistics (Tally, State, and Output Statistics in Simio)

Page

In this lab, we learn how to use user-defined statistics (Tally, State, and Output statistics) to evaluate performance metrics that are not built-in in Simio. The videos will guide you through:

  1. Understanding different types of performance measures (Observational Time-persistent)
  2. Learning how to code user-defined Tally, State, and Output statistics in Simio
