QUEUING SYSTEM

In computer systems, queues occur in front of almost all systems and components, such as, CPUs, disks, switches, links, and servers. This course, specifically designed for computer science students will help you to understand the impact of your design decisions on the response times and buffering required at various resources. The course deals with the modeling and analysis of queueing systems, with applications in communications, manufacturing, computers, call centers, service industries and transportation. 

A basic understanding of probability and statistics is helpful in this course. This page is constantly being updated. Watch out for the lecture slides and other relevant materials and download them as soon as they are posted

Some areas to be covered in this course include:

  • Introduction and general overview of Queuing Systems
  • Cost Equations, Little’s Formula, and Steady State; 
  • Basic Components of a Queue
  • Kendall Notation A/S/m/B/K/SD
  • Queuing Models
  • Rules for All Queues
  • Little's Law
  • Stochastic Processes
  • Birth-Death Processes
  • Poisson Distribution
  • Poisson Processes
