From modeling to optimization : solving the Stock Size Problem with JuMP and its compatible state-of-the-art solvers
Introduction In a context where the supply chain has become a central and structuring component of the Industry 5.0 ecosystem, recent research is shifting toward a new paradigm: Supply Chain 5.0. This paradigm aims to integrate advanced technologies in order to design highly intelligent, adaptive, and sustainable logistics networks. Among the key topics associated with Supply Chain 5.0, inventory management plays a central role. In particular, the stock size problem,

When business-oriented software meets real life: what SEDIT teaches us
In our first article, we discussed the differences between “ideal scenarios” and actual work practices, and what these differences mean for the design of business-oriented software. In this second installment, we move from theory to practice: how did we measure these differences using SEDIT, an HRIS system from Berger-Levrault used in public administrations? The general
Usage discrepancies: when business software meets real life
Do users really follow the paths carefully mapped out by designers? And when reality goes beyond the scope of the design—which happens more often than we think—how can we know this other than through intuition and assumptions? On a daily basis, business-oriented software supports very concrete activities: managing leave, processing absences, tracking careers, producing regulatory

Enhancing Functional Testing Efficiency in Industrial Large-Scale Applications: Pertinent Test Selection
Introduction In modern software development, application reliability relies on effective testing strategies. Altough unit and integration tests secure internal consistency, functional testing remains essential for validating user-facing behaviors. For large-scale applications like Alpha Tool, running thousands of functional tests is challenging: it consumes vast resources, slows down delivery, and complicates analysis. This article explores the
Investigating Hand-Bound Pads for AR Input Using Hand-Tracking Only
What is Augmented Reality, and how is it used for Augmented Maintenance? Augmented Reality (AR) has emerged as a powerful tool for enhancing human-computer interaction, allowing digital content to be seamlessly integrated into the physical world. Unlike traditional desktop or mobile interfaces, AR enables spatially situated interactions, where virtual content is embedded within the user’s
Making Large Numbers Count: Cognitively Informed Alternatives to Log-Scale Bar Charts
From carbon emissions to national budgets, we’re frequently asked to interpret values that span from thousands to millions and billions. These wide ranges—what we call Orders of Magnitude Values (OMVs)—are cognitively demanding for the general public and hard to represent with common charts. So, how can we make sense of large numbers in order to
Explanation of the Coruscant Mobile project
This research is the result of a collaboration between Ali Can Kocabiyikoglu, Pascal Zaragoza, and Vincent Laval, part of the AI Laboratory | BL Research Team. The Challenge of Modern Maintenance Support A maintenance technician faces an unfamiliar “Error 20” on a medical device. Their hands are busy with tools, eyes on the equipment, yet
From law to customer in seconds: automating legal compliance
Adherence to legal mandates is crucial for businesses, as failure to comply can lead to substantial penalties. In an environment where legal documents are constantly evolving, companies increasingly rely on automated processes to streamline analysis and to ensure ongoing compliance. The full automation process typically involves: (1) extracting legal terms and their relationships, and (2)
Airflow: feedback on BL.Predict and Foundation use cases
Introduction In a context where the automation of data workflows has become a fundamental pillar of project reliability and scalability, Apache Airflow has established itself as an essential tool within the technical ecosystem of our BL Research team, dedicated to Research and Technological Innovation at Berger-Levrault. Whether orchestrating text document processing chains or driving transformations
