Forecasting

Forecasting is at the heart of decision making in OR. It is the basis for planning and control activities, it drives decision making on products and services, from the strategic to the operational level, and is a critical input to finance, marketing, logistics and production, across sectors from business to government. This stream attempts to capture the plethora of methodological approaches and application areas in a series of coherent special sessions, relevant both from an academic and a practitioner perspective.
Topics include, but are not limited to the following:

- Econometric Forecasting,
- Financial Forecasting and Risk Analysis,
- Forecasting and Planning Systems,
- Forecasting Electricity Load and Prices,
- Forecasting for Logistics and Supply Chain Management,
- Forecasting for Workforce Management,
- Forecasting Processes,
- Forecasting with Neural Networks,
- Forecasting Support Systems,
- Hierarchical Forecasting Systems,
- Integration of System Dynamics and Forecasting Models,
- Intermittent Demand Forecasting (Forecasting of Count Series),
- Inventory Forecasting,
- Judgemental Forecasting,
- Knowledge Sharing and Organisational Learning,
- Performance Measurement.

Mixed-Integer Non-Linear Programming

Mixed-Integer Nonlinear Programming (MINLP) is a sub-field of Mathematical Programming specializing in modelling and solving one of the most general (and hard) classes of optimization problems: namely, problems including both nonlinear terms and integer variables. There are countless real-world applications: in energy production, chemical engineering, scheduling, software verification, quantum chemistry, air traffic management, bioinformatics, nuclear engineering, and water distribution, for example.
Small and medium scale MINLPs are currently solved using a Branch-and-Bound variant called "spatial Branch-and-Bound" (sBB), where branching is allowed on continuous as well as discrete variables that contribute to the gap between the original problem and its convex relaxation. For large-scale variants one must currently resort to heuristics, such as VNS, Feasibility Pump, Local Branching; or exploit the problem structure to derive special-purpose methods. Alternative approaches are studied for special cases of MINLP problems, like, for example, convex MINLP and  MIQP problems.

Sessions and talks focusing on both methodological developments and applications are welcome.

The ROADEF/EURO challenge

The ROADEF/EURO challenge is an international computational programming competition on a complex industrial optimization problem, jointly organized by ROADEF, the French Operational Research and Decision Support Society and EURO.
This year the challenge is proposed by Google. It is dedicated to a machine reassignment problem. This challenge is open to everyone, and particularly to young researchers, excluding people professionally involved with the industrial partners.

The aim of this challenge is to improve the usage of a set of machines. A machine has several resources as for example RAM and CPU, and runs processes which consume these resources. Initially each process is assigned to a machine. In order to improve machine usage, processes can be moved from one machine to another. Possible moves are limited by hard constraints, as for example resource capacity constraints, and have a cost. A solution to this problem is a new process-machine assignment which satisfi es all hard constraints and minimizes a given objective cost.

The ROADEF/EURO challenge 2012 stream will welcome presentations of the finalists, selected after the qualification round that ended December 8, 2011. The results will be announced and prizes will be awarded  during the EURO Conference in Vilnius.

Machine Learning and Its Applications

The stream includes both the theory and the practice of Machine Learning and Data Mining. The talks devoted to statistical as well as heuristic methods of ML are welcome. The stream includes topics on regression analysis, forecasting, classification, clustering, multidimensional statistics as well as their practical applications in the fields of financial sector, information retrieval, text processing, computer vision, speech recognition and knowledge extraction.

Environmental Issues in Operations Management

Environmental issues like scarcity of resources and green house gas emissions play an increasing role in operations of companies. Therefore, it is necessary to regard environmental issues in production planning, but also in procurement and distribution decisions. Moreover, environmental aspects play an ever increasing role for performance measurement and management of supply chains.

In this context, the stream “Environmental Issues in Operations Management” at EURO XXV calls for abstracts describing concepts, methodologies, models and tools for integration of environmental aspects into operations management of companies and supply chains.

Topics of interest are (but not limited to):
- sustainability assessment and performance measurement
- energy and resource efficiency
- emission reduction measures
- product recovery
- green procurement
- supply chains for biofuels
- investment decisions
- production planning
- life cycle assessment
- green/sustainable supply chain management
- carbon management in industry/in supply chains
- impact of environmental regulation on production and supply chains

Proposals for sessions (4 papers) as well as general inquiries can be addressed to the stream organizer. Contributors are also requested to contact the stream organizer for the submission (invitation) code. We look forward to meeting you in Vilnius!

Young People for System Theory, Optimization and Education

The future of OR depends on the new generations of researchers, who often have to solve organizational problems to succeed in their career. Lack of organization skills and information about different opportunities often prevents them from doing magnificent discoveries. To find out how to make the life of OR community's newcomers easier, such questions will be
discussed:

- motivation to do OR-research - excellence in science and the modern applications,
- troubles that new scientists deal with at the beginning of their career,
- different features of doing research in developed and developing countries,
- young people in organization of scientific and educational projects, such as summer schools, conferences and seminars; introduction and support of new and given successful formats of conferences and encouragement to them all over the world,
- opportunities for young researchers,
-OR-education, strengthening of the disciplines within OR and, especially, interdisciplinarity.

Scientific examples will be included throughout.

We are looking forward to discuss these and related topics with you!
