Predictive simulation is the science of creating accurate models to represent the behavior of real-life processes.

Today’s businesses are facing increasingly difficult and complex decisions. Markets are changing constantly, competition is fierce, and customers are demanding innovative new experiences and consistently high service levels. Predictive simulation simplifies this complexity. A simulated model of your business generates powerful future-state data and helps demystify much of the analytical process by providing a rich interactive visualisation of information. Predictive simulation helps both analysts and decision-makers understand their business processes, data and how they affect one another across diverse sectors such as manufacturing, LNG, supply chain, logistics and more. 

Why predictive simulation?

Evidence-based decision making

Analyse ideas and 'what-if' scenarios where testing in real life would be impractical, expensive and dangerous

Operational safety and efficiency
Quantify risk and enable data-driven decision making to support strategic and operational efficiency and safety
Secure stakeholder buy-in

Communicate challenges and opportunities more clearly, accelerating stakeholders and investor buy-in

Maximise return on investment

Understand the impact of change to help optimise resources and drive higher return on investment

Research

Read our latest research

As leaders in simulation and digital twins, our work was recently featured in the Operational Research Society's Simulation Workshop 2025. In this paper, we examine the benefits of using an ontology and knowledge graph (KG) approach in developing and maintaining discrete-event simulation (DES) models.
