Document Summary

> it works terribly when there is variation! Why? (once behind, you never can catch up) > queuing theory quantifies these tradeoffs in terms of performance measures. > (mathematical) queuing models help us set capacity (or determine the number of resources needed) to meet: > queuing models provide an alternative to simulation. > they provide insights into how to plan, operate and manage a system. > service facilities are usually classified in terms of their number of servers (or channels), and number of phases (or service stops) that must be made. > triage nurse in ed, di with one ct, one doc on night shift, > often take a complex problem, and treat it like a single server: > e. g. , cataract surgical patients may have complex flow with multiple servers . We can pretend that the or is a single server and ignore downstream servers. Several parallel single server queues: e. g, grocery store ->
