Vallourec
Case Study: Improving the production quality of forged tubes.
Challenge
World leader in premium tubular solutions, Vallourec ensures the highest quality of its products through state-of-the-art processes and rigorous evaluation systems.
The use of machine learning solutions is a necessity for the continuous pursuit of excellence in production.
N-Hence Manufacturing:
Multidimensional analysis to narrow down possible failure causing agents
Statistical modeling with penalty strategy x artificial balancing, to find the most relevant attributes.
ML algorithm for predicting defect occurrences.
Online dashboard for parameter simulation and optimization.
Results:
All actions from the N-Hence Manufacturing solution generated excellent results for the company. Some example include:
- High ability to separate defect-generating versus non-defect-generating variables.
- Prioritization of the variables that most impact the generation of defects.
- Optimization of corrective actions.
Impact
The model was able to predict, in the worst case, 66.7% of the defects and, in the best case, 83.6% of the failures.
