STOR-i POP 2022 (Hybrid)


STOR-i Workshop on Prediction and Optimisation, Lancaster University, 16th-17th June 2022

What is this about?

Analytics solutions typically involve two main tasks among others:

  1. prediction,
  2. optimisation.

They are now widely popularised as predictive and prescriptive analytics, but they are usually conducted separately.

Title: Hidden gems in supply chain demand forecasting.

Abstract: Demand forecasting is a strategic process within supply chain management. Although, usually, the main discussion of the forecasting process deals about which forecasting model (or machine learning/IA counterpart) is more accurate in terms of point forecasts, in this talk, I will be focused on three forecasting problems of great importance in supply chain management that, in my view, they have not drawn enough attention. We will start with the problem of how information sharing of end demand between companies of a supply chain can enhance the demand forecasting accuracy of upwards supply chain members. In this case, we will analyse the forecasting approaches employed to incorporate information from different echelons in a supply chain to improve the demand forecasting accuracy. The second hidden gem will be the utilization of parametric and non-parametric forecasting approaches, typically used in finance applications, to optimize the safety stock size. Finally, the third hidden gem will explore the impact of the lost-sales inventory assumption on the demand forecasting exercise. In this case, we will connect this problem with the traditional statistical literature of censored estimation, and we will propose an engineering tool as the Tobit Kalman Filter as a general solution.

He has been a visiting researcher at Paris Descartes University in France (June 2007-September 2007) and a posdoctoral researcher at Lancaster University Management School in UK with a Marie-Curie Intra-European Fellowship (April 2008-August 2010).  Currently, he is working as a Full Professor at the business administration department at Facultad de Ciencias y Tecnologías Químicas in University of Castilla-La Mancha. He is co-director of the research group Predilab (Predictive Analytics Laboratory). His research interests are focused on forecasting problems related to supply chain management and energy systems. Within supply chain, he has experience in supply chain demand forecasting; impact of collaborative mechanisms on the bullwhip effect; assessment of judgmental forecasting; calculation of the safety stock; and development of supply chain simulation software. Regarding energy system he is interested in load electricity forecast at short and mid-term horizons; price electricity forecast at short-ter

Title: Robust Optimization Approaches for Sustainable Energy Infrastructure

Abstract: In this talk we present robust optimization approaches for sustainable energy infrastructure. First, we develop robust portfolio models of clean and renewable energy production over time to meet local and state governments’ short-term and long-term clean energy goals, incorporating concepts from project finance to finance the building of critical new infrastructure in the presence of demand uncertainty and price uncertainty. We model and mitigate a wide range of risks both pre-completion and post-completion to create a comprehensive strategy to achieve renewable energy goals. Second, we also design tractable, robust approaches for vehicle fleets to achieve portfolio-wide emission goals in line with the new Greenhouse Emissions Standards put forward by the U.S.’s Environmental Protection Agency in December 2021. We use customer choice models to create portfolios of new vehicles that best allow car manufacturers to fulfill the preferences of various customer segments while addressing the climate crisis. Further, we investigate various financial incentives. Our models are relevant for state and local policymakers as well as individual customers.

Title: Prediction in algorithmic behaviour

Abstract: We overview aims, techniques methodologies and recent developments of techniques from data science and machine learning that allow to predict and improve instance specific algorithmic behaviour. We distinguish on-line techniques, that is, data science techniques integrated into advanced algorithms, off-line techniques which can be used to improve, select or construct algorithms as well as techniques that consider the problem as living in a space of which the dimensions are set by specific properties of its instances. We discuss some examples of recent results obtained for specific problems. We give an example where a recent theoretical result for a combinatorial optimization problem provides new insights that can be used to locate a region of hard problem instances in the instance space, and hence provides insight in what impacts the expected long term behaviour of an algorithm package in a real world context.

Bio: Patrick De Causmaecker obtained his PhD at the Institute for Theoretical Physics of the University of Leuven in 1983 under the supervision of Raymond Gastmans. From 1994 on he has successfully conducted research in heuristic optimization and constraint solving, especially in scheduling and rostering. He is especially interested in structures and quantitative methods to gauge and improve the performance of optimization algorithms. From October 2005 onwards he was a full professor with the department of Computer Science at KU Leuven, Campus Kortrijk. Together with his colleague Greet Vanden Berghe, he created the CODeS Group within the department of Computer Science. In 2021, he became a Professor Emeritus. He chairs the European Working Group ‘Data Science meets Optimization’ which supports activities at EURO and several workshops such as the one at IJCAI in 2022. He is on the steering committee of the PATAT series of conferences, and co-organizes PATAT 2022, August 30-September 2, in Bruges, Belgium.
