Queueing Theory
Definition
Queueing theory studies waiting times and utilization of limited processing capacities.
The mathematical study of arrival, waiting, service, and utilization in systems with limited capacity.
Simply explained
It helps estimate how arrival volume, processing speed, and available slots affect waiting.
Why it matters in practice
The term contributes to secure, maintainable, and high-performance web applications as well as resilient technical decisions.
Example from business
A team estimates how many workers are needed for a target waiting time.
Limits and pitfalls
- Assuming Poisson arrivals or constant service times without verification and ignoring peak loads.
Origin & history
The field originated in the early 20th century from the analysis of telephone networks and was transferred to production and IT.
Use in mid-sized companies
- Possible application: A team estimates how many workers are needed for a target waiting time.
