Quantitative Analysis BA 452 Supplemental Questions 9
Objectives
By working through the homework questions and the supplemental questions, you will: 1. Be able to identify where waiting line problems occur and realize why it is important to study these problems. Know the difference between single-channel and multiple-channel waiting lines. Understand how the Poisson distribution is used to describe arrivals and how the exponential distribution is used to describe services times. Learn how to use formulas to identify operating characteristics of the following waiting line models: a. Single-channel model with Poisson arrivals and exponential service times b.
