Ciw is a discrete event simulation library for open queueing networks. :hatching_chick:

Read the documentation here. A repository of example Jupyter Notebooks is also available.

History

v0.2.11 (2017-03-13)

Add ability to simulate until max number of customers have passed arrived/been accepted/passed through the system.

v0.2.10 (2017-03-10)

Performance improvements. Drop dependency on numpy.

v0.2.9 (2017-02-24)

Allow zero servers.

v0.2.8 (2016-11-10)

Add option for time dependent distributions.

v0.2.7 (2016-10-26)

Run tests on Appveyor. Check docs build and pip installable on Travis. Remove hypothesis cache.

v0.2.6 (2016-10-17)

Add AUTHORS.rst. Add progress bar option.

v0.2.5 (2016-10-06)

Fix bug that didn’t include .rst files in MANIFEST.in.

v0.2.4 (2016-09-27)

Fixed bug in which priority classes and dynamic classes didn’t work together. New feature: preemptive interruptions for server schedules.

v0.2.3 (2016-07-27)

Ability to set seed. More docs. Fixes to tests.

v0.2.2 (2016-07-06)

Baulking implemented, and minor fixes to order of unblocking.

v0.2.1 (2016-06-29)

Priority classes implemented.

v0.2.0 (2016-06-20)

Python 3.4 and 3.5 compatible along with 2.7. Data records now kept in list.

v0.1.1 (2016-06-06)

Ability to incorporate behaviour nodes. Data records are now named tuples.

v0.1.0 (2016-04-25)

Re-factor inputs. Simulation takes in a Network object. Helper functions to import yml and dictionary to a Network object. Simulation object takes optional arguments: deadlock_detector, exact, tracker. simulate_until_max_time() takes argument max_simulation_time.

v0.0.6 (2016-04-04)

Exactness implemented. Restructure some features e.g. times_to_deadlock. Custom simulation names.

v0.0.5 (2016-03-18)

State space tracker plug-and-playable. Add rejection dictionary.

v0.0.4 (2016-02-20)

Empirical and UserDefined distributions added. Tidy ups.

v0.0.3 (2016-02-09)

Arrival distributions. MMC options removed. Fix server schedule bugs.

v0.0.2 (2016-01-06)

Some kwargs optional. Hypothesis tests. Minor enhancements.

v0.0.1 (2015-12-14)

Initial release.

v0.0.1dev (2015-12-14)

Initial release (dev).
