How Witness Works

Create virtual models of facilities and operations
  • Spreadsheets can’t replicate the intricacies or range of real-life challenges – but with Twinn Witness, the drag-and-drop interface makes it easy to swiftly create models (or digital twins) that mirror your business processes
  • Incorporate a range of data – from Excel files to cloud services – by linking to your external tools
Combine discrete events with continuous flows
  • Build models that incorporate continuous process elements (fluids flowing through pipes, for example) as well as variable events – helping you find the most efficient and cost-effective solution across multiple scenarios
  • Flexible functionality gives you the power to visualise solutions to a multitude of operational and strategic challenges – replicating the range and complexity of real-life business problems
Switch between 2D, 3D and abstract visualisation
  • Plan and design your model layout in 2D – then switch seamlessly to whichever view maximises impact for stakeholders
  • Choose 3D for an immersive visual experience or view your model as an abstract process flow – providing an in-depth understanding of multiple what-if scenarios facing your business
Leverage simple yet powerful logic coding
  • With Twinn Witness, there’s no need for complex coding – instead, develop your logic in compartmentalised blocks within the process simulation software
  • Use powerful coding techniques – either from Twinn Witness or external code libraries such as C++, C#,, or Python, when required
Unlock unparalleled business intelligence
  • Use the power of predictive simulation to run parallel replications with different scenarios – Witness Experimenter finds the best solutions to complex questions quickly
  • Dynamic charts and reports provide answers to key stakeholder questions, empowering you with predictive analysis and data to transform business processes – plus export simulation data seamlessly for external analysis
Discover comprehensive support
  • With getting started workbooks, video tutorials and sample models, Twinn Witness predictive simulation software is easy to use
  • Twinn provides training designed to optimise your modelling capability, whether you’re a first-timer or a seasoned pro
  • Maximise value with the help of our expert consultants – depending on your requirements, we’ll provide support with building models or deliver a comprehensive service to optimise predictive simulation results

Twinn Witness predictive simulation software plays a crucial role in our business forecasting because it enables accurate, system-level thinking. The fact I was able to use this technology from the beginning and embed it in our day-to-day work has made a huge difference.
