Validation in one day instead of five

Challenge

In structural and stress calculations, engineers must compare thousands of time series from non-regression tests after every change. That takes days - time that should go into interpreting the results, not comparing parameters.

Solution

• Decision assistant based on machine learning - it identifies which test is regressing and which parameters cause it.
• Focus on the engineer’s judgement - the machine compares, the human assesses.
• From idea challenge to production - the idea came from an internal SII innovation challenge, was developed in a four-year publicly funded research project and then industrialised.

Result

• About five times faster: a standard validation takes one day instead of five.
• Passed a blind test on unknown data - after which the client commissioned industrialisation.
• Rolled out across programmes from 2023 to 2025 and fully operational today.
• Fewer loops between design and calculation, better optimised model configurations.

Part of a bigger picture

The validation assistant is one of several AI research projects we drive along the entire V-model of product development:
