queueing theoryΒΆ
These examples involve processes where the states are integers that increase or decrease stochastically by one step at a time, over continuous time.
These kinds of processes are also called birth-death processes. When the count only increases and cannot decrease over time, this is called a pure-birth process. Similarly when the count only decreases and cannot increase over time, this is called a pure-death process.
In some of the examples a complication that may be unusual in traditional queueing theory is considered: a branching timeline.
