Haskoning Witness simulation modelling software
What is Witness?
Witness is simulation modelling software that lets you create dynamic virtual models of real-world processes, facilities and operations. By simulating how a system behaves over time, you can explore ideas, test changes and understand their potential impact before implementing them in the real world.Use Witness to experiment with different layouts, resources, capacities, schedules and operating rules, helping you identify bottlenecks, compare alternatives and uncover opportunities to improve performance.
Supporting both discrete-event and continuous simulation, Witness can model complex processes across manufacturing, logistics, supply chains and service operations. Built-in experimentation, analytics and 2D and 3D visualisation help turn simulation results into insights you can use to make better-informed decisions.
Why Witness?
Improve performance
Make confident decisions
Understand complex processes
Explore what's possible
Every strategic or operational challenge raises important questions. What happens if demand shifts? How should resources be allocated? Where are the best opportunities to improve performance or invest for the future?
Witness gives you a risk-free way to explore the answers. By bringing processes and operations to life through simulation, you can test different scenarios, understand the potential impact of change and uncover insights that are difficult to see in static analysis.
See how Witness helps turn complex challenges into clearer, more confident decisions.

Witness features and functionality
In today’s world, it is necessary to have tools that allow you to choose the best scenario quickly and without high investment – that’s why we need simulation software.
We immediately used the model...it gives us confidence in our analyses and builds trust from stakeholders that we have an evidence base covering all implications.
We’re no longer just relying on people’s experience. Instead, we have real data: we can run scenarios, identify interdependencies and get to an accurate outcome faster.

Plan with greater confidence
Effective planning gets harder as operations become more complex, variable and interconnected. A change in one area can have unexpected consequences elsewhere, making it difficult to predict the best way forward.Simulation helps you understand those interactions before making changes in the real world. With Witness, you can test different scenarios, optimise processes and explore how decisions could affect performance – helping you plan with greater insight and confidence.
