Optimise your business processes with AI and simulation
At the beginning of last year, we welcomed the UK-based predictive simulation expert Lanner into the Royal HaskoningDHV family. This means we also welcomed WITNESS, one of the world’s leading predictive simulation solutions – and we’re already using it to help our clients across the globe optimise their processes.
The reason we’re so excited is that this simulation know-how perfectly complements the AI and data science capabilities we already possess. Where AI and data science are both powerful tools, there are still a whole host of problems that are better solved using simulation: for example, when there just isn’t any data to train AI-based models, or when the dynamics of a system are too complex to fit a model to.
By having experts in both approaches operating under the Royal HaskoningDHV banner, we can deliver even greater insights to our clients going forward.
Combining AI and simulation technology: a hidden opportunity
What’s really got us excited though, is the possibility of using simulation and AI together to provide even more value from our services.
For example, what if we could use simulations to train our models (as seen in reinforcement learning)? Or the other way around – can we see our models working in simulated environments before deploying them in the real world?
After giving this some thought, we came up with about 8 possible ways of combining AI and simulation. For now, we’re exploring two of those possibilities with one of our US-based industrial clients:
- Can we speed up the optimisation process by having an AI analyse simulation outcomes and point out possible improvements?
- Can we speed up or extend simulations by replacing time-consuming models with fast AI approximations?
Speeding up the optimisation process
Our client has already developed detailed simulation models of their facilities, and are using them to analyse possible optimisations. But imagine being an analyst looking for possible optimisations in 10,000 simulated years of facility operations. And in an environment with hundreds of machines. That’s a huge challenge. And when you want to do this continuously, to iteratively come up with improvements that you can test, that challenge becomes more complex and more time-consuming.
That’s why we’re looking at how AI can speed up these processes, using machine leaning models that can automatically identify areas for improvement when going through simulation outcomes. The goal is to make the analyst’s job easier – but that’s really just the start. Ultimately, we want to generate new scenarios based on these identifications and feed them back into the simulation. If we can do this, we will effectively have an AI-based optimisation engine that could be used across all verticals.

Extending simulations with fast AI approximations
The image above is probably familiar. What it doesn’t tell you is that a machine learning model can be much faster than a “traditional” model.
True, that speed might come at the cost of lower accuracy, but in many cases that’s not a problem. Going from a 15-minute to sub-second compute time is worth it, especially if we’re considering a model that needs to be used for decision-making inside the simulation numerous times.
By combining AI with simulations, we’re confident we can deliver insights to our clients much faster – and we’re in the process of doing so right now.
AI and simulation become parents to twins, digital twins!
It is not hard to see how these AI-infused simulation models, fed with real-time data, can provide prescriptive functionality to digital twins.
Take this example:
- A digital twin uses AI to detect an impending failure in a pump. It predicts the pump will fail in 90 days.
- Again using AI, the twin also detects that this pump is a critical part of your process. It then uses simulation software to find an improved solution, and suggests replacing the pump with a bigger version.
- Using simulation software, the digital twin identifies an optimal time to replace the pump with your new bigger version – 60-65 days from now.
Thanks to the combination of AI and simulation software, this problem is identified and solved with optimum efficiency – and with minimal human interaction.
The Royal HaskoningDHV approach
At Royal HaskoningDHV we spend a lot of our time working with clients to co-create digital twins tailored to their needs, incorporating IoT, AI, data science, simulation, machine learning and our 140 years of domain expertise.
