We at Ventana Systems sadly mark the passing of Jay Forrester, pioneer in servomechanism control, digital computing, System Dynamics and global modeling. We hope that our tools and our work may carry on in Jay’s spirit, to help people better understand and manage complex systems, tackling the biggest problems with courage and integrity.
The latest beta is #E48, October 6th. Get it here. There are several improvements over the September release, but one that’s particularly helpful is color-coordination of entity traces across multiple charts: We’re preparing for commercial release, so this version is testing licensing infrastructure. For the moment, this could hardly be easier – just click the
The latest beta is #E30, September 27th. Get it here. There are many refinements in this version, and stability is very good. There are too many items to list, but here are a few representative improvements: Causal tracing tables simplify debugging Copy-paste stability much improved Multi-sliders for Synthesim-like control Optimization with vector inputs and outputs
At the System Dynamics Conference in Delft, we showed a complementary new product – Ventity – that solves some problems that can be intractable in most simulation languages. Here’s a quick preview: There’s a Ventity poster and more detailed white paper in the conference proceedings: Ventity Poster ISDC 2014 Entity-Based System Dynamics White Paper
