WebThe birth–death process (or birth-and-death process) is a special case of continuous-time Markov process where the state transitions are of only two types: "births", which increase the state variable by one and "deaths", which decrease the state by one. It was introduced by William Feller. WebA simple queuing model in which units to be served arrive (birth) and depart (death) in a completely random manner.
