Abstract

Expand your skills with these two 45' practical sessions: Make Easy Changes, Make Changes Easy: A Tutorial On OR Coding Quality; followed by Tricks From The Trade For Large Scale Optimisation.

(i) Make Easy Changes, Make Changes Easy: A Tutorial On OR Coding Quality (Michele Quattrone, Air Liquide)
The implementation of well-thought-through quality strategies on the software lifecycle is becoming a requirement for many software developments, even for the early mock-up/prototyping phases. In this 45-minute tutorial, backed with a practical example, we will discuss together how our coding can benefit from this strong push, and what we can cherry-pick from hyping buzzwords such as DevOps, Continuous Integration, Continuous Deployment, MLOps...in practice!

(ii) Tricks from the Trade for Large-Scale Optimization in a practical context (Andreas Schmitt, Zalando SE)
Have you had to face up to optimization challenges, where you have had to develop and deploy heuristics in order to implement models into production environments? This session will use the speaker's experience of a successful application as a starting point for discussion.

Practical optimization problems often quickly increase in scale and complexity, necessitating tailored solution approaches. Our talk describes heuristics designed to work along-side a Lagrangian decomposition method, leading to almost-optimal solutions. These have been developed in the context of the frequently applied ’predict-then-optimize’ paradigm, more specifically for markdown pricing strategies in the online fashion industry. We present empirical evidence for the heuristics’ effectiveness, drawing on pricing applications at Zalando SE.

This exposition will serve as a starting point for discussions: Participants will be encouraged to explore questions such as: What are your experiences with similar optimization challenges? How do you approach heuristic development in their work? What are effective approaches for deploying such models into production environments and measuring their impact?
