2021 System Dynamics Conference

Welcome to the Ventana Systems SD Conference landing page. We look forward to seeing you virtually!

Ventana Systems, Inc. Ventana helps clients solve hard problems in strategy, operations, marketing and public policy. We integrate models and data to provide insights that machine learning and systems thinking alone can’t access. These pages give some examples of our work and describe our approach.

Vensim Vensim is an industry standard simulation tool, enabling large models with extreme speed and serious data management, at the center of a large ecosystem, and supporting education with free PLE:

Software

Vensim PLE – free for educational and personal learning use, including the workshop. You can always download a copy at https://vensim.com/free-download/.  After the conference, we ask that commercial and government users purchase an inexpensive license for continued use other than workshops and software evaluation.

Vensim DSS trial for the workshop and exploring advanced features of Vensim – good for 60 days. Use the following license key:

Company : Limited Time Evaluation
Unlock code : NXCEI-SWA8F-7DCT8-O8

Download DSS using the company name and code as above.

Ventity is unlocked through the end of September – you can download a copy from https://ventity.biz/update/ . Note that Ventity requires Windows (Mac emulators are fine), and Win7 compatibility can’t be guaranteed due to End-of-Life issues.

Bonus Material

Vensim Calibration morning participants – the Live Repeat session video has a more complete coverage of MCMC. I’ll do a further upgrade after the conference.
