PTV Group – “Strategic optimization with PTV xCluster and Gurobi”
Bernd Welter, Technical Partner Manager, PTV Group

What you do wrong in the strategic area cannot be repaired operationally. This is what most people overlook when they optimize their data in various sectors and industries on a day-to-day basis. Retailers, service technicians, field sales force, freight forwarders and many more. Small-scale optimization is often carried out day after day and the long-term view of strategic and tactical data is neglected.
Bernd Welter introduces us to this often overlooked part of processes and how to optimize them with PTV components.
From the annual territory planning of the entire sales force, to the multi-week visit pattern planning of an individual employee (of course, taking into account overnight stays and in compliance with the legal framework), PTV offers the xCluster Service, a high-performance interface that masters the following tasks:
Territory planning: Optimal assignment of customers to their locations, including even load distribution or with heterogeneous team sizes.
Expansion Planning: Where Should They Open New Locations? Where to hire new employees?
Coverage Planning: How can you maximize customer coverage with minimal operational costs?
Visit pattern planning: How do you optimally plan your recurring customer visits for a given planning period and ensure that the daily working hours are adhered to? How often and where should they stay?
This is where Gurobi and PTV come into their own, because it is precisely these advanced features that can only be solved as quickly as possible and with the best quality using the professional solver.

M2P Consulting – “Gurobi & CBC – The open source project “python-mip”
Sebastian Heger, Senior Consultant, M2P Consulting

In this lecture, a brief look beyond the horizon of Gurobi should be thrown. Under the umbrella of the COIN-OR Foundation, a new Python module was created in 2019 to integrate the open-source optimizer CBC and the Gurobi product. In contrast to existing Python APIs, which integrate several solvers, for the first time, extensive features such as callbacks and cut generators are available through direct and fast connection of the C interfaces of both solver libraries. In addition to the feature presentation of the Python module, practical experiences from M2P product development will also be shared, in particular the advantages and challenges of combining the commercial and open source optimization worlds.

German Football League (DFL) – “A masterpiece of man and computer”
Andreas Farr, Sr. Manager Spielplanung & Spielleitung, DFL – Deutsche Fussball Liga & Stephan Westphal, Professor, Clausthal University of Technology

18 clubs, 34 match days, 306 games, each club has 17 home and 17 away games and meets every other club exactly twice. There are also countless specifications from internal and external stakeholders. These are the framework conditions for the preparation of the match schedules for the League and League 2. A few years ago, the plans were still created manually using the so-called English key. Each club was assigned a number between 1 and 18 and fitted into a given scheme. This automatically resulted in encounters. Individual adjustments outside of the schema were not possible. In order to break up the rigid system of the English key and to meet the increasingly complex requirements, the DFL now works with its own software that enables the creation of individual game schedules. The software uses the method of integer linear optimization. Without this technical support, the goal of creating the best possible game plan could hardly be achieved.

Quantum Block

1- Introduction by Richard Oberdieck, Technical Account Manager, Gurobi Optimization

2 – “Quantum Computing Incubation Journey: Opportunities & Challenges” by Dr. Sebastian Senge, Technology Innovation Strategy Manager at Accenture’s global Quantum Computing practice and a co-lead in the ASG region

Is Quantum Computing here to stay? Many companies are looking into this fascinating technology to assess its inherent value for their business. In this talk we will present Accenture’s perspective on the potential benefits of Quantum Computing and the challenges on the incubation journey. Additionally, we will showcase samples of our client projects and our holistic Quantum strategy. In this regard, classical solvers for mathematical programming, like Gurobi, are a crucial part of our approach as a benchmarking tool as well as a way to offer full “algorithmic agility” in order to implement end-to-end processes and systems already today and to move to QC gradually as the technology matures

3- “EnerQuant – Optimization for the energy industry with the help of quantum computing” by Dr. Michael Trebing, ITWM

4- “It takes two to Tango” by Dr. Sebastian Senge and by Dr. Michael Trebing

5- Closing by Richard Oberdieck, Technical Account Manager, Gurobi Optimization

5- Q&A

McKinsey – “E2E Supply Chain Planning Optimization in Agriculture”
André Fuetterer, Solution Leader for Manufacturing and Supply Chain Optimization, McKinsey

We supported a global grain processor and exporter developing a tactical supply chain planning optimization application, spanning the complete value chain from farms to customers. This helped our clients to realize 10% increase in throughout, 30% reduction in vessel and rail demurrage, 2% reduction in transportation cost and 3% margin uplift from optimized product mix. The application was centered around a MILP model with Gurobi as a solver embedded into a web-based application for automated data refresh, validation and plan and scenario generation. To build capabilities and ensure acceptance of the solution, End-users from supply chain, commercial and operations were fully part of the process: from designing the user experience to testing the solution and providing constructive feedbacks.

Optano- “Rapid Projects: Was kann man von Math. Optimierung in Beratungsprojekten lernen?
Jens Peter Kempkes, CEO, Optano

The lecture shows best practices and transferrable concepts to make projects faster, more effective and more robust.
Among other things, the following questions will be discussed: How can mathematical optimization be used in consulting in such a way that the best possible results are achieved? Which cooperation models are suitable, which typical mistakes can be avoided? What aspects should be considered when selecting the technology? And how can the transition be designed after the consulting project?

HelloFresh – “Art meets Operations Research – Menu Planning”
Robert Dochow, SCM – Operations Research Lead, HelloFresh

Menu planning as art? At HelloFresh, we see the weekly selection of recipes we offer our customers as a kind of art. Namely the art of maximizing the satisfaction of all our customers. Every week we put together our menus in such a way that from a large selection of recipes we provide those that pursue this goal, taking into account many conditions for different diets and sufficient variety. From a mathematical point of view, menu planning is a nested knapsack problem and can therefore be optimally solved using operations research methods.
