Queueing and COVID19
Last update: May 1, 2020.
The global pandemic has resulted in a
number of [new] queueing
situations. If you would like to send me (M. Hlynka, U of Windsor) an email at hlynka@uwindsor.ca
and add your comments, please do so. I will include names and e-mail
addresses unless instructed otherwise. If you want to read others'
comments, see below (if anyone chooses to comment).
Warning: Someone (not
me) may steal any ideas you mention, and others may ask to do joint
research with you. Let's start.

- April 6, 2020. M. Hlynka writes: If one looks at the Covid-19 cases by
country with cases and deaths, one observes that the proportions are not
even close to being constant. Does this mean that the countries with a
high proportion of deaths relative to cases, are simply not detecting all
the cases and that explains why the proportion is so high? Or is something
else happening here?

April 5, 2020. M. Hlynka writes: "We note that there is (or will be) a
shortage of respirators for covid-19 patients. This is essentially a double sided
queueing system."
https://www.hindawi.com/journals/jat/2019/6538265/
We have patients needing respirators, whereas
earlier we had respirators sitting and waiting for patients. The
classic example of double sided queues is taxi cabs and passengers
where in some circumstances we had cabs waiting for passengers and in
other cirucumstances we had passengers wating for cabs.

In these times of covid-19, there are rules for social distancing,
including the number of people that be inside a store. Today I went to a
local pharmacy. The pharmacy is a store with many
aisles of other items (food, magazines, beauty items, etc.) for sale.
Some items (e.g. paper products, hand sanitizer) were in short supply
or sold out.
The sign on the entrance door said Maximum
capacity = 50 people. There were 3 people waiting in line outside and they
were allowed in one at a time as individuals left the store. The fact
that there were only 3 people waiting may mean several things.
That there was any waiting at all suggests that the arrival rate must be
close to the service rate. Further, the fact that there were so few people
waiting suggests that this may be a situation of queueing with balking or
queueing with discouragement.
