Modelling and Simulation

Confident decisions start here

In critical industries like transport and utilities, even small changes can have big consequences. But predicting how those changes will play out – in complex systems and for the people who depend on them – is rarely straightforward.

That’s where modelling and simulation tools help. They let you test ideas in a safe, virtual space and see what might happen before making real-world decisions – or costly investments.

Our team uses these tools across critical infrastructure to help clients spot challenges early, improve performance, and move forward with confidence.

Our heritage

Graffica, part of Sopra Steria

In 2022, Sopra Steria acquired Graffica, a specialist provider of simulation products, software systems and consultancy services to the transport industry. Now fully embedded into the Sopra Steria family, the team continues to deliver cutting-edge solutions that enhance operational efficiency, safety, and decision-making across the transport sector.

Our core services and offerings

Simulation platforms are tools that mimic real-world systems for testing and development purposes. Our platforms support your research and development needs for concept evaluation, experimentation, demonstration, and trials.

Our platforms are architected to seamlessly integrate with a wide range of third-party systems, such as live surveillance, simulators, and prototype applications, through various industry-standard interfaces.

We offer the perfect platform for prototyping ideas and concepts. Before you commit to a new system or major contracts, we can:

  • Test and refine requirements on our simulation platforms.
  • Emulate the proposed system's functionality and user interface.
  • Provide a system for technical, human factors, and operational evaluations.
  • Eliminate the costs of prototyping on an operational system.

We create secure, safe, and scalable operational systems, which range from centralised data processing hubs through to Europe-wide distributed and connected airspace management tools.

We have developed a suite of bespoke software solutions to address the toughest of industry challenges, from three-dimensional airport environments to high-fidelity rail network simulators.

Five steps to rail transformation
The rail sector is under pressure. Rising passenger demand, tighter timetables, ambitious decarbonisation targets, budget pressures, and major infrastructure projects are stretching capacity and resources. Operators need to be able to make faster, smarter decisions – without compromising safety, service, or sustainability.
