Controlling arrival and service rates to reduce sensitivity of queueing systems with customer abandonment
Katsunobu Sasanuma, Robert Hampshire, Alan Scheller-Wolf
The Erlang A model--an M/M/s queue with exponential abandonment--is often used to represent a service system with impatient customers. For this system, the popular square-root staf…
Approximate Performance Measures for a Single Station Two-Stage Reneging Queue
Katsunobu Sasanuma, Alan Scheller-Wolf
We study a single station two-stage reneging queue with Poisson arrivals, exponential services, and two levels of exponential reneging behaviors, extending the popular Erlang A mod…
Markov Chain Decomposition Based On Total Expectation Theorem
Katsunobu Sasanuma, Robert Hampshire, Alan Scheller-Wolf
A divide-and-conquer approach to analyzing Markov chains (MCs) is not utilized as widely as it could be, despite its potential benefits. One primary reason for this is the fact tha…
