Experience Analytics: an Operations Management View

In service contexts, consumers usually travel a complex journey, structured as a sequence of interactions taking place in space and time. While these journeys have been conceptually described, their detailed dynamics are poorly understood. Only recently our community has started to use analytics to better identify what triggers certain behaviors. A process view can be extremely useful to track engagement over the journey and identify experience improvement opportunities. In this talk, we develop a Markov-Decision Process framework that integrates contextual physical and digital factors to model consumer behavior over journeys. We apply the model to distinct contexts such as museum visits, e-commerce navigation and city mobility.

Co-optimization of energy and reserves in European energy markets

The ambitious goals for the integration of renewable energy sources in modern energy systems in order to combat climate change implies that the electricity supply chain becomes increasingly reliant on energy sources that are inherently and, to a large extent, unpredictable and out of human control. Reserves are backup resources that are needed in order to ensure that the electricity system can operate reliably despite the significant uncertainty caused by the massive integration of renewable resources. In addition to trading energy and access to networks, electricity markets worldwide are evolving in order to improve their processes for procuring reserves. Among numerous engineering challenges that this objective raises, one can single out formidable computational challenges for optimizing the allocation of conventional generation capacity between the provision of energy and reserves, and ensuring the delivery of these reserves over networks. The institutional challenges are also important, since the economics of price formation in electricity markets are deeply affected by how reserves are compensated and the conventional roles of network operators and power exchange operators become increasingly intertwined. This presentation presents a brief overview of the organization of electricity markets and discusses the aforementioned engineering and institutional challenges, the state of play in the European energy market, as well as the potential welfare benefits and institutional implications of exploiting operations research in order to achieve a smoother coordination of conventional resources as “dancing partners” to renewable energy resources.

Recent trends in combinatorial optimization augmented machine learning

Combinatorial optimization augmented machine learning (COAML) is a novel and rapidly growing field that integrates methods from machine learning and operations research to tackle data-driven problems that involve both uncertainty and combinatorics. These problems arise frequently in industrial processes, where firms seek to leverage large and noisy data sets to better optimize their operations. COAML typically involves embedding combinatorial optimization layers into neural networks and training them with decision-aware learning techniques. This talk provides an overview of the field, covering its main applications, algorithms, and theoretical foundations. We also demonstrate the effectiveness of COAML on contextual and dynamic stochastic optimization problems, as evidenced by its winning performance on the 2022 EURO-NeurIPS challenge on dynamic vehicle routing.

Collaborate for Good: Orchestrating Sustainability in Supply Chains

Tentative Abstract: Firms are under increasing pressure from their stakeholders to adopt sustainability measures for the goods or services they produce. However, the risks and opportunities associated with sustainability go beyond a firm’s own operations and extend to their supply chain partners. In this talk, we will explore ways in which firms can enhance sustainability in their supply chains through collaboration.

Just in case, here is also my short bio: Tarkan Tan is a professor of Sustainable Operations Management at the University of Zurich since September 2022. Prior to that, he worked at Eindhoven University of Technology and TIAS Business School in the Netherlands. He received his Ph.D. from Middle East Technical University in Ankara and was a Fulbright scholar at Columbia University, New York. Additionally, he has served as a visiting scholar at the University of California, Los Angeles and the University of Sydney Business School. His research interests include inventory theory, capacity management, spare parts management, and supply chain management, with a focus on sustainability. Prof. Tan serves as an associate editor for the Manufacturing & Service Operations Management journal and has served as a guest and associate editor for other journals in his field. He co-edited a book entitled “Sustainable Supply Chains: A Research-based Textbook on Operations and Strategy”.

Modeling with stochastic programming

There are many deep papers on the mathematics and algorithmics of stochastic programming. But why should we, as operations research people, care? The world is stochastic for sure, but does that imply that we need stochastic models to get good decisions? And if we embark on a genuine application, where real money is involved, what are the modeling questions we need to pose? What are the steps we need to take before we arrive at mathematical and algorithmic challenges?
