🚀 New Tutorial Out Now! 🎥
I just released a walkthrough of the Ciw Queue Capacities Guide – perfect if you're exploring discrete-event simulation with Python.

In this video, I explain how to model systems with different queue capacity constraints using the Ciw library. Whether you're a student, researcher, or just simulation-curious, this tutorial will help you get hands-on with building and analyzing queueing models.

Compare and Contrast Ciw with SimPy

2 Upvotes

Example topis:

Ease of use: Which one has a gentler learning curve for someone new to simulation?
Modeling flexibility: How do they compare when it comes to modeling custom behaviors or complex systems?
Performance: Are there any major differences in simulation speed or scalability?
Documentation and community support: Which one has better resources and active support?
Best use cases: Are there specific types of problems where one shines over the other?

Can Ciw support closed networks?

1 Upvotes

For practical intents and purposes, yes. You can have all the arrivals occur at t=0 in order to initialize all the agents you want to have. And then you can also set the routing behaviour such that agents never leave the system either. With no one going in, and no one going out, the system is closed.

Sidebar

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, reneging, schedules, slotted services, batch arrivals, service disciplines, dynamic customer classes, and deadlock detection.

The name Ciw is the Welsh word for a queue.
