  • Modular Entities

    This video demonstrates the use of entities to: represent markets with sparse offerings and new product introductions, create new structure on the fly, from data or random events model multiple scenarios simultaneously for an aggregate infection model, model the same infection process on an agent based social network, and calibrate a function to time series

  • Vensim Model Import

    One of the newer features of our recent releases is the Vensim Model Import tool, and we’d like to take a few moments to walk through some of its uses and some tips for importing models from Vensim to Ventity. The first thing to keep in mind is that importing a Vensim model can only

  • Data Science meets the bottom line

    Ventity can be used to put big data in context, by incorporating the learnings from big data in simulations that account for organizational structure and finances. Ventity can also do data intensive simulation, with an architecture friendly to relational data and dynamically changing lists, optimization for calibration, and much more  on the road map.

  • Ventity 4.6 Beta

    The Ventity 4.6 beta is primarily an under-the-hood performance enhancement, with a few bug fixes and feature improvements as well. The primary feature enhancements are to Process List actions, making it easier to restrict the number of iterations, and much faster to make small randomized selections from large entity collections. This version is stable in

  • Ventity 4.5 Release

    Ventity 4.5 is now available for download or upgrade. There are some further performance improvements over 4.4, as well as a few critical bug fixes to the Initial() and DelayInformation() functions. A number of minor bugs have been fixed as well, including the occasional tendency of autocomplete to delete left parentheses when adding variables to

  • Doing Classic SD in Ventity

    Ventity extends the System Dynamics paradigm with a number of features that enable dynamic cohorts, agents, networks and other hybrid simulation features. However, Ventity is pretty great for simple, aggregate dynamic models, too. You don’t need to know about its advanced features to put the entity architecture to good use by automating suites of policy
