Air France – Optimization in the airline industry : an overview of our use cases & challenges
Benoit Robillard, Chief Technical Lead of Operations Research and Data Science, Air France KLM

The airline industry offers a wide range of optimization problems to tackle a wide range of challenges to solve. This journey will guide us through some of our most emblematic use cases such as revenue management, crew rostering optimization or schedules maintenance operations showing how optimization and Gurobi can bring value to our business. We will highlight different optimization patterns that we have and see how tackle them not only depending on their combinatorial complexity but also, even mainly, regarding the whole process it belongs to.

Mars – PLATO – An In-House Supply Planning Tool
Jana Färber, Senior Data Scientist, Mars

Mars has been exploring innovative alternatives to the demand and supply planning system used in major markets. This created an opportunity to design an in-house planning tool that creates optimized production plans based on Mars-specific hard and soft constraints. Several production lines, accountable for 49 % of production volume in Mars Wrigley Confectionary, are considered particularly complex to plan for. Within those lines, several items need to be produced concurrently while output rates per item may vary depending on the combinations selected, and the time of production. The tool that Mars’ in-house Supply Chain Analytics Team has created uses Gurobi to solve for optimized production plans while seamlessly integrating with the new demand and supply planning system. It responds in real-time and allows Supply Planners to step through multiple settings of the hard and soft constraints, providing a scenario planning capability not available to them to date. The case study is going to highlight the implementation and architecture chosen for deployment.

BlaBlaCar – Optimization of the long-distance bus network @BlaBlaCar
Thomas Bernardi, Data Scientist, BlaBlaCar

Operating a long-distance bus network of 1 million km per year spread over 300 buses as efficiently as possible is a huge challenge. On top of that, these buses are distributed among more than 40 partner companies, each with their own operational constraints, this is where optimization algorithms become essential to help with decision-making. Thomas will present the vehicle scheduling algorithm they developed, and show how the close collaboration between Data Scientists and Software Engineers enabled them to integrate it in the existing tech stack of the tools used by Network Planners.

Ian Griffiths, CTO, Decision Lab

Inefficient transport of goods can be incredibly wasteful in terms of people and time, fuel use, environment impact and financial cost. This is especially important for the military that must get vital military equipment and supplies to the right places at the right time. Funded by Defence Science and Technology Laboratory (Dstl, a part of the UK Ministry of Defence) – through a Defence and Security Accelerator competition, we developed the Logistics Optimisation System (LOGOS) that provides more rapid, effective handling in Deployed Military Logistics Hubs. It is composed of three optimisation algorithms – a stores routing algorithm, a pallet packing algorithm, and a transport loading algorithm – which link to the Gurobi solver. Through further Dstl funding, we have since extended this to optimise the support long-term military logistics demands. We have also carried out a project for Microsoft which applied Reinforcement Learning to a similar problem. We will present the our modelling approach and its potential use in military and wider logistics, and how a mathematical optimisation and machine learning methods can complement one another.
