  • 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

  • Entity Selection by Attribute

    Need to see all the model year cohorts of diesel vehicles in your fleet? No problem. Ventity’s Entity Picker lets you select entities for viewing by model run, unique ID, or any entity attribute. Similarly, you can create collections of entities by attribute, and use those to compute aggregates – sum, average, maximum – for

  • Interactive Charting
