Notes

Queueing theory originated in 1909 with a paper written by a mathematician named Agner Krarup Erlang.
 He accurately estimated the probability that a call would be blocked at different capacity utilization levels.

It can provide essential insights to product developers because there're similar problems of unpredictable work arrival time and unpredictable task durations.

Queueing systems:
 Queue: the waiting work.
 Server: the resource performing the work, whose time to complete the work may be unpredictable.
 Arrival Process: the pattern with which work arrives, which is usually unpredictable.
 Service Process: the process in which the server accomplishes the work.
 Queueing discipline: how queue handles the waiting work.

Kendall notation: $M/M/1/\infty$ queue.
 The first $M$ refers to the arrival process, in this case, is the Markov process.
 The second $M$ refers to the service process, which is also a Markov process.
 The number $1$ refers to the number of parallel servers in the system.
 The final term $\infty$ describes the upper limit on queue size.

Queue Service Process
The queue service process is the process in which the server accomplishes the work.
Zettelkasten, August 04, 2021Markov Process
A Markov process is a random process in which the future is independent of the past, given the present.
Zettelkasten, July 24, 2021M/G/1 Queue
In queueing theory, an M/G/1 queue is a queue in which the arrivals are a Markovian, service has a general distribution, and a single server.
Zettelkasten, August 31, 2021Queue Capacity Utilization
Queue capacity utilization is the amount of time the service process is working (not idle).

A vector space, or linear space, is a set of objects called vectors. It's possible scale by numbers, called scalars, and add these vectors together.

The critical path is the most extended sequence of activities in a project plan. The project is only completed on time only if you meet these activities.
