Vensim 6.0 released.

Post by Administrator » Thu Jul 05, 2012 10:05 am

Vensim 6.0 is now available for download or purchase in the Vensim store.

Version 6.0 introduces a new look and new features.

- Interface Changes
- A new Equation Editor layout
- Improved Toolbars and Cursors
- Optimization Features
- Stochastic optimization : optimize over an envelope of Monte Carlo simulations
- Discrete constraints on optimization parameters, so you don’t waste time determining whether to build 2.6 or 2.7 factories.
- Extended payoffs with non-Gaussian errors, logarithms, and mixed calibration/policy variables.
- Markov chain Monte Carlo & simulated annealing
- Extended payoff report information with MAPE and Theil statistics

See http://www.vensim.com/documentation/version_6_0.htm for the full release notes, with a video introduction at http://vensim.com/video.html.

You can upgrade to the latest version of Vensim easily – just follow the Upgrade link at http://vensim.com/download.html and enter your license code. Can’t find it? No problem – contact us for help.

If you're not current with 5.11, there are some interesting new features, including:

- Significant upgrades to the Help system, including improved indexing and nearly 100 sample models illustrating the use of almost every built-in function
- Native Mac support (licenses are portable across platforms)
- GET DIRECT functions that can access spreadsheets and other delimited data files, like the GET XLS functions without the overhead of launching Excel.
- The option of observing integer constraints in the ALLOCATE AVAILABLE function
- great for managing allocation of discrete items like customers or aircraft.
- Enhancements to the document tool and SyntheSim functionality with lookups in large models
- On-the-fly configuration of subscripts (arrays) with the GET DIRECT SUBSCRIPTS or GET ODBC SUBSCRIPTS functions
- great for matching model detail to your data.
- :EXCEPT: statements that let you handle exceptions to subscripted equations more easily.

The Vensim team is hard at work on the next great thing (stay tuned).

Tony.
