- Title of the talk: From Decision to Optimization
The seminar will address the modeling problem in Multi-criteria Decision Situations. We will discuss variety of situations where the researcher has to transform the real problem into a solvable model. We will present the different transformation strategies and the implications on problem solving. Research examples will be provided and illustrated. We will deal with uncertainty when addressing many objectives. We will address dynamic situations as the optimal stopping problem. Interactive decision making situations will be also briefly presented.
- Bio: Fouad Ben Abdelaziz is currently Professor and head of the MSc in Supply Chain Management at NEOMA Business School, France. He was a Senior Fulbright scholar at the Rutgers Center for Operations Research, Rutgers University, NJ. He received his PhD in Operations and Decision Systems from Laval University, Canada. He has been working at the American University of Sharjah, University of Dubai, The American University of Beirut, and the University of Tunis. He is a leading researcher in multi-objective stochastic optimization with applications to SCM and Multi-attribute portfolio selection problems. Aside his publications in outstanding journals like EJOR, JORS, IJAR, FSS and CAIE, he served as Guest Editor for European Journal of Operations Research and Fuzzy Sets and Systems. He was also the chair and the organizer of many international conferences as the Multi-objective and Goal Programming Conference MOPGP and the International Conference on Multidimensional Finance Investment and Insurance ICMFII.

- Multi-objective Optimisation – Past, Present and Future
Multi-objective optimisation is concerned with the simultaneous optimisation of several conflicting objective functions. Many scholars attribute the origin of this field to Vilfredo Pareto. Nevertheless, the term “Pareto optimality’’ was coined only 50 years later. The real history of multi-objective optimisation as a mathematical discipline begins in the 1950s when economists published first mathematical results. Since then the field has grown many prosperous branches, such as multi-objective linear programming, multi-objective combinatorial optimisation, evolutionary multi-objective optimisation and so forth. With increasing computing capabilities, it has also become possible to apply our methods to real world problems. Today we are in a situation, where the tools of multi-objective optimisation have a very strong theoretical foundation and can be applied to problems of sizes relevant to real decision makers. This, I think, opens many possibilities for the future of this field. In this talk, I will sketch the history of multi-objective optimization from its early sources to the bright outlook for the future.
- Bio: Matthias Ehrgott studied Mathematics, Economics and Computer Science at the University of Kaiserslautern in Germany where he obtained Masters (1992), PhD (1997) and Habilitation (2001) degrees. In 2000, he moved to the Department of Engineering Science at the University of Auckland, New Zealand, as a lecturer and became full Professor and Head of Department in 2011. Since 2013, he works at Lancaster University Management School. He served as Head of the Management Science Department from 2014-2017. Matthias’ research interest is in multi-objective optimisation, which he applies in a variety of areas such as medicine, transportation, and manufacturing. He has published about 80 journal papers, book chapters and proceedings contributions on theory, methodology, and applications of multi-objective optimisation. In addition, he has authored and edited about 30 books, proceedings volumes and special issues of journals on the topic. The book “Multicriteria Optimization” (Springer, 2005) is a standard monograph in the field. In total, his work has been cited more than 11,000 times (Google Scholar). He serves on the editorial board of several journals including Computers & OR and Journal of Global Optimization. Since 2002, he has been on the Executive Committee of the International Society on Multiple Criteria Decision Making, where he is president elect for the period 2019-2023. In 2011, he received the Edgeworth-Pareto award of that Society. He organized the 19th International MCDM Conference in 2008 and was on the programme committee of many other international conferences, including several MOPGP and MCDM meetings.
