  1. ETM 607 – Simulation Software and Arena Modeling • Review simulation software. • http://www.lionhrtpub.com/orms/surveys/Simulation/Simulation1main.html • “Hands-on” experience with a discrete-event simulation software package, Arena. • simple single server queue • input, model logic, outputs • additional logic features • In-class exercise, model and analyze complex process

  4. ETM 607 – In-Class Exercise • Camshaft Machining Line – Process Details • Develop an Arena Model of the Camshaft Machining Line • Include unplanned downtime • Include dress cycles • Determine the minimum number of machines for each operation to support a production rate of 250 camshafts per shift • Assume a shift is 450 minutes • Output Analysis • Report queue sizes, machine utilization, machine downtime for various “number of machine” combinations. • Provide a recommendation for the number of machines for each operation. • Email group results to schultz_sr@mercer.edu
