  • Data-Friendly Architecture

    Ventity fits relational and ad hoc data sources naturally, because it represents detail with collections of entities rather than arrays. You can enter data easily, with convenient builtin tables or spreadsheet links.

  • Dynamic Structure

    In Ventity, you can introduce new entities on the fly during a simulation. You can introduce them via data, or programatically with discrete Actions. Introduce a firm into a market when you need it, or delete a cohort of products when they’re all sold. Simulate and review just your real behavior, without lots of clutter

  • 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
