Welcome to Ciw’s documentation!

Ciw is a discrete event simulation library for open queueing networks. Its core features include the capability to simulate networks of queues, multiple customer classes, and implementation of Type I blocking for restricted networks. A number of other features are also implemented, including priorities, baulking, schedules, and deadlock detection.

The name Ciw is the Welsh word for a queue.

Ciw is currently supported for and regularly tested on Python versions 3.6, 3.7 3.8, and PyPy3.
