LIST OF SESSIONS AND ABSTRACTS, ‘MAKING AN IMPACT’, EURO2018
Practitioners who use MIP have a great choice of possible softwares. The huge choice can make it harder to make decisions; and that’s where this session should be invaluable.
Bringing together representatives from the 3 top stand-alone MIP-solvers, Gurobi, Xpress and CPLEX with representatives from 2 companies and 1 university that are heavy users of one or more of these we try to answer questions like: Why use a 3rd party solver instead of specialised heuristics? What problems have companies experienced in this approach? And of course… which solver is the best in practice?
The rise of so-called Mat-heuristic solvers that incorporate a mip-solver as part of the heuristic has seen a large increase in the last years. In this panel discussion we make a deep dive into that world from the usability perspective.
Chair: John Hopes, President, The Operational Research Society (UK)
Academics and practitioners have different incentives, and different contractual, personal and professional objectives, but there are considerable areas of overlap and opportunities to learn from each other. This is the third successive EURO conference to bring academics and practitioners together for a question-and-answer panel. A summary of the output from the previous two discussions is here.
Previous panels have considered the obstacles in the way of academic-practitioner collaboration, and ways of overcoming them. This panel will focus particularly on how we can get the best from each other: what would academics like practitioners to know and do, and vice versa. A brief recap of the conclusions from previous panels will be followed by short introductions from several experienced academics and practitioners, followed by questions and contributions from the audience.
Introduction: Ruth Kaufman, Stream leader, Making an Impact and Chair, EURO Working Group on Practice of OR
Discussants:
Sally Brailsford

People with OR skills and knowledge are in great demand in industry. There are many possible career paths open to OR people outside academia, whether they are starting with no more than a first degree in a scientific subject, or with a PhD and post-doctoral experience in OR. In this session, panel members with very different career paths will briefly describe their career history and current ambitions, the skills they started with, and the important developments along the way; and then open up to discussion with the audience. The purpose of this session is for people at all stages of an OR career to explore ideas about what they may want to do in the future, and what sort of development and training may be useful.
Panel members are:
John Hopes, President of the Operational Research Society (UK)
Kerry Malone, Senior Scientist, Department of Sustainable Urban Mobility and Safety, TNO
Michele Quattrone, R&D engineer, operational and data science team, Air Liquide
Nicole Havinga, ORTEC
CONFERENCE SPECIALS: get the most from being at EURO
One of the most important reasons for coming to a conference is to build your circle of professional acquaintance – with like-minded people who can encourage and inspire you, and with not-quite-so-like-minded people who can challenge and extend you, and with the many people who you can encourage, inspire, and challenge. However, it is not always easy to meet people when most of our time is spent sitting listening to presentations. The speed networking session is a supportive, managed way of meeting people you don’t know: a series of short, quick-fire sharing of professional information with other participants, together with an exchange of contact details if you meet somebody you want to keep in touch with. Latecomers will be admitted but may have to wait for a few minutes before they can join in. The meeting will also include a short presentation about the EURO Working group on Practice of OR, aimed at supporting a pan-European network of practitioners.
At a EURO conference there is an enormous amount of interesting material that any one person can only see a small fraction of. This session will help boost that fraction. Each presenter will have just 5 minutes to present a lightning talk: a maximum of 20 slides at 15 seconds per slide. This will be an opportunity for presenters to get a bigger audience for your key ideas and for the audience to get a wide variety of fast-moving and stimulating talks. Details of presenters within the session will be available in due course. The line-up and order are subject to change.
Lightning talk abstracts
Professional Football Planning Lukas Bach, Sintef
Football is important to many people, just see the FIFA World Cup. When planning a tournament, this gives rise to many wishes from fans, associations, TV and clubs. Among these we have to find the optimal solution.
Influencing client meetings through conversation framing Ashley Carreras, Loughborough University
Framing strategies – ie how you focus clients’ attention on key topics – influence the path of client/consultant meetings. Conversational analysis, within a framing context, has been used to analyse client/consultant meetings occurring between a series of facilitated workshops. What can we learn from this?
Expanding your set of objectives: Behavioural Decision Analysis in action Valentina Ferretti, London School of Economics
Behavioural science has shown that, when confronted with strategic decisions, we tend to generate about half of the relevant objectives. What could be possible solutions? This talk will share lessons learned from a recent project with a Foundation in Hungary that provides educational opportunities to underprivileged children.
Agri-Food Value Chain Decision-Making under high risk and uncertainties; strategies for EU and South America Jorge Hernandez, University of Liverpool
What are today’s key agri-food challenges? How are they affected by Food Safety, Climate Change, Nutrition and Food Waste considerations? I will be describing the international collaboration between UK, France, Spain, Italy, Poland, Chile and Argentina to design new agriculture production systems policies.
Anticipating the Future Using Problem Structuring Methods David Lowe, Defence Scence and Technology Lab
Organisational change is typically triggered in reaction to performance issues. This presentation examines whether routine internal use of Problem Structuring Methods can guide anticipatory change with reference to a case study drawn from the United Kingdom Ministry of Defence.
Connecting research with policy – some examples from TNO Kerry Malone, TNO
TNO connects university research with business and policy, for governments and industry. The overview provides examples of research questions that span various Technology Readiness Levels – from 2 or 3 in the Early Research Programs, to 5-7 in our knowledge development programs.
Behaviour, behaviour, and behaviour in multi-criteria policy analysis Gilberto Montibeller, Loughborough University
Every policy decision involves conflicting objectives and policy makers with distinctive perspectives. From my experience in supporting complex policy prioritisations there are three key behavioural factors for high-impact and successful interventions, which I will highlight in my talk.
Waste treatment & disposal supply chain optimisation (in practice) Matteo Pozzi, Optit
Practical application of a multi-period, multi-commodity flow model to the waste treatment and disposal supply chain of the largest Italian Waste Management Company will be described, as an example of how OR can be integrated in real-life business processes (with great impacts!)
Matching number of trucks to demand Michele Quattrone, Air Liquide
Air Liquide ships a huge amount of gas cylinders by trucks, serving more than 2 million customers. How can we estimate the cost and feasibility of an entire year of delivery from one truck to a group of customers? Can Montecarlo methods help?
Solving the real problem Björn Thalén, Jeppesen
I will share experiences from airline crew planning and talk about how to Jeppesen leverages MIP-solvers in practice. Will also talk about the difference between applied OR science and applied OR practice.
Evaluation as a service for solving practical optimization problems Szymon Wasik, Poznan University of Technology
Evaluation as a Service is a concept of storing all evaluation data and procedures in the cloud. Here, I will present an Optil.io – a unique platform that can be used to solve industrial optimization problems by evaluating algorithms solving them and by organizing crowdsourced programming challenges.
A comparison of different curbside waste collection systems Sanne Wøhlk, Aarhus University
If countries are to meet the EU goal of 50% recycling, how can local authorities best adapt their systems for curbside collection of household waste? We analyze the driving needed under different scenarios, comparing ‘collect, then sort’ and ‘sort, then collect’ systems using single and multi-compartment vehicles.
Rolling stock maintenance scheduling Daniel Palhazi Cuervo, Sintef
We discuss the scheduling of the maintenance tasks that need to be carried out by Mantena, the main provider of rolling stock maintenance in Norway. Handling multiple operational constraints and various levels of granularity make solving such problem particularly challenging.
Multiagent Planning in Aviation Anders Albert, Sintef
From aviation, both airspace and airport management require multiagent planning. We will present a general problem of coordinating planning activities that require multiple resources controlled by different stakeholders in an airport setting.

IMPROVE YOUR SKILLS AND PRACTICE: participative sessions
Probably we can all relate to this: while discussing we seem to agree, but we each have a slightly different thing in mind. This is fine if we are just having a cheerful chat at the bar; or even for a research endeavour: the starting vision may differ from the end results but all involved parties still be happy and proud of the achievements. But what if we are to deliver a product that is going to be used? What if the expectations lead to deceptions? If a deliverable is a physical device one can be sure about the way to interpret the specifications; and if one is delivering a well-known type like a building, a bridge or a vehicle then there are many examples to relate to, so all parties probably expect the same outcome. However, OR consultancy shares the glory of being innovative with the curse of laying the first step. The chance that the involved parties share the same vision is much smaller.
To make things worse, the actors involved bring to the table different knowledge. Those involved in the business take rules for granted and those developing the solution produce models where rules are either present or not, they cannot be just assumed. We may therefore produce the optimal solution to the wrong model: neither feasible nor attractive to the customer.
This workshop aims at exchanging experiences and lessons learned to help each other manage expectations and avoid misconceptions. A good solution to the right problem seems much harder to find than we might expect!
Often brilliant optimization results are not viewed as such by various stakeholder during OR implementations. There can be multiple reasons for this. Is the solution of high quality (low cost, high revenue), but are the stakeholders just not used to the solution which is presented to them? Or did we not optimize the actual problem that needed to be solved? Maybe there are conflicts in requirements: the stakeholders may not be aligned on what they find the best solution to their problem.
The challenge in practice is how to tackle the problems mentioned above. This means first of all finding which problem we actually have to solve. It also means that stakeholders have to accept that the solution presented to them could be different than they expect, but could still be of high quality when looking at the goals. Therefore it is essential to this process to define the success criteria. When multiple success criteria are defined, it needs to be identified what the prioritization is, especially when there are conflicting requirements. Quantifying the results and comparing them to a baseline is how we can show the stakeholders that the presented solution solves their problem.
During this session we will open the discussion with some example use cases. We are looking forward to your experience and input.
Due to a sudden increase in the number of customers, parcel delivery company X realizes the time has come to apply optimization software for automatically creating efficient delivery routes. To prepare the shift from manual to automated planning, a team of OR specialists working for company X get together to compile a complete and unambiguous list of requirements, a clear definition of the problem that needs to be solved, and a desired outcome, supported by some insightful, illustrative examples. A full problem definition is presented to the optimization software consultancy.
If the situation described above was at all realistic, our job at ORTEC would be a lot simpler than it is. In practice, developing supportive optimization software for a wide range of customers operating in a fast-moving, competitive, and unpredictable market is no walk in the park. Most steps leading to the problem definition have gaps and difficulties that ORTEC first needs to resolve. This workshop is aimed at anyone interested in applying OR in practice. In an interactive way we will share our best practices, address challenges faced, and skills required when bringing OR into practice with help of real-life vehicle routing problems.
The amount of data in the world is constantly growing at an enormous pace. That offers opportunities for consultants to provide factual insights to their customers. The customer can profit from these insights by taking the right (fact-based) decisions. This is in fact what OR-consultants have been doing for a couple of decades already. Recently however, terms like Analytics, Predictive modelling, Machine learning, and Data Science have become much more popular than Operations Research. Does that mean that OR has become redundant? Can quantitative consultants support decision making without using or even knowing typical OR-models and OR-techniques? Are techniques the most important at all?
We think Data Science and Operations Research should go hand in hand. And we believe business understanding and modelling remain indispensable skills in our work. We illustrate this with some of our typical projects of the last few years. And we invite you to discuss with us. How do you think quantitative consulting should be done?
The first conference of the Euro Working Group on Practice of OR was held in Paris-Saclay in February, resulting in an exceptional opportunity for more than 40 top level practitioners from various industries to confront each other on the issue of “measuring the impacts of OR projects”. Starting from the key highlights of the event, this session is aimed at carrying on this discussion leading towards the next event, to be held in Bologna next winter.
Come if:
– you were in Paris and cannot wait to bring this forward;
– you are keen to see how OR is applied in the real world;
– you have been wondering about what are the best KPIs to demonstrate the impacts of your OR models;
– you are curious to know what interests the most in the community of industrial service players who use OR to innovate and improve their processes.
Bring your own views, share them with us, join the community, contribute with your own experience to help OR becoming increasingly relevant in the industry.
This session is aimed at analysts and consultants, and at teachers/trainers of business modeling. No prior experience is needed. Simulating business challenges and plans has until recently been difficult and time-consuming – but things have changed! We will take you through an “agile” process that makes quantified, working simulations practical for non-experts to build, quickly and reliably. And we need these tools. Spreadsheet-based methods just cannot handle the interdependencies, feedback, thresholds and intangible factors that infect all but the simplest cases. The resulting Living Business Models display with total transparency precisely the factors that management recognises, and exactly the causality that drives the performance outcomes they are interested in. Since everyone sees the same rigorous picture, they get that “joined-up” view that everyone says they want – fully explaining how everything has been changing, and allowing them to explore likely future outcomes under alternative assumptions, decisions and strategies.
What is the main goal of our customers in Transport Logistic Sector when it comes to route optimization? Not surprisingly – saving money. In order to achieve this goal it is essential to be able to calculate ‘practically adequate’ shortest paths in huge road networks extremely fast. Practical adequacy requires the consideration of a plethora of additional data such as predicted and live traffic information, vehicle- and time-dependent toll prices as well as physical and legal limitations. Since this data is becoming increasingly accurate and available it is essential to exploit this technological progress in the calculation to get the most realistic result. As vehicle characteristics and start times vary in shortest path web services with every single calculation the use of speed-up techniques often has limitations in real life use-cases.
In this session we present challenges we as PTV Group had to face when incorporating different data in our shortest path algorithm, we show how we dealt with these challenges in our applications and use-cases and invite you to comment and share your own experiences.
The session is aimed at OR practitioners who deploy applications to business users. Deploying applications requires a functional architecture and the corresponding technical architecture to be well defined. Most of the Euro conference is dedicated to OR techniques and applications; this will be a short introductory session to the 50-70% of work that needs to be done to get an OR model to deliver value to a business user. Participation in the discussion from practitioners is very welcome.
When it comes to modern and widely accessible programming languages two camps seem to attract comparable amounts of attention and collectively dominate: R and Python.
R seems to be preferred by the statistics and data science communities, while Python seems to be the language of choice of the artificial intelligence and mathematical optimization communities. This classification is by no means limitative, since there are many other good choices such as Julia, Jump, Java, C, C++, C#, Matlab, Octave, etc.
Nevertheless, the perception that R is not for optimization may interfere with the possibility to merge great libraries and tooling for (big) data analysis with optimization.
This tutorial gives data scientists familiar with R a glimpse on how to use it for optimization and other scientists familiar with optimization a glimpse of the power of R. The tutorial includes examples of data driven optimization using R both as a platform to develop heuristic methods and as an interface to mathematical optimization solvers. To get the most from it, please bring your own laptop with an internet connection.
Ethical practice is important if practitioners are to retain the trust of their clients as well as their own self-respect. There are a number of codes of practice available for anybody who wants guidance on this. But even for the most ethical practitioner, real life can sometimes throw up ethical dilemmas, or tempt us into imperfect behaviour: perhaps fulfilling our contract obligations may require turning a blind eye to unethical conduct from the client; or the client does not want to engage with the caveats around our analysis; or we want to convince the client to employ us even where the work area is new to us, to name just a few situations where a purist approach may result in no OR work happening at all.
This session will start with a short introduction to the ethical dilemmas that can arise in everyday OR, and then open out into discussion inviting participants to share their own experiences and approaches. It is intended to give an opportunity to people engaged in practical OR to reflect on their own practice and to share learning and ideas with others, so that they may be better equipped to make good choices in future.
