Discrete Event Introduction

Review and such

• questions?
• Fallacies

  Here are two possible models for run length:

  run-length1.mox
  run-length2.mox
  

• Run length models
• CDF using Excel
• CDF using tables
• standard units

New Material

Discrete Event Simulation

• time steps
• entities or items
• queuing problems
• animation
• The M/M/1 queue: exponential interarrival and service times. Let's build one! You'll need the following blocks, all in the Discrete Event library.
  • Executive
  • generator
  • queue
  • delay (service)
  • exit
• Run it with and without animation.
• simulation setup
• paradox of means: what's the queue length and wait time if arrivals are μ=1 and service is μ=0.9?
