Lab 3 – Queueing Networks

Page

This lab involves solving a queueing network problem by hand and in Excel. We will also use the Excel queueing model to perform what-if analysis. The videos will guide you through:

  1. Understanding the basics of queueing analysis
  2. Solving the queueing network by hand
  3. Using the Excel model of the queueing network to perform what-if analysis (we will use Excel’s Data Table to accomplish this task)
  4. Developing a Simio model of the queueing system to verify our “solution” calculated by hand
