Integrating advanced discrete choice models in mixed integer linear optimization

Michel Bierlaire, Shadi Sharif Azadeh, Meritxell Pacheco Paneque, Bernard Gendron

The integration of customer behavioral models in operations research (OR) is appealing to operators and policy makers (the supply) because it provides a better understanding of the preferences of customers (the demand) while planning for their systems. The ...

Introduction to disaggregate demand models

Michel Bierlaire, Virginie Janine Camille Lurkin

Demand information is an input for a great deal of operations research models. Assumed as given in many problem instances addressed in the literature, demand data are difficult to generate. In this tutorial, we provide an introduction to disaggregate deman ...

A test of inventory models with permissible delay in payment

Ralf Seifert, Olov Isaksson, Daniel Seifert

Contrary to the long-standing view in the finance literature that firms should maximise payment delays, research in operations management suggests that long payment delays can be suboptimal. In this study, we reconcile these two views by applying a seconda ...

Stochastic impulse control with regime-switching dynamics

Yaroslav Melnyk

Optimal product management problems with multiple product generations in continuous time lead to the consideration of dynamic optimal control problems that feature both intervention costs and partially controlled regime shifts. We therefore investigate and ...

Editorial

Maria Jesus Rodriguez Triana

Learning is a complex, mostly invisible process that happens across spaces, occurring in the physical world but also increasingly in virtual worlds or web-based spaces. In order to explore what happens in such blended learning experience, there is a need ...

On turnpike and dissipativity properties of continuous-time optimal control problems

Dominique Bonvin, Colin Neil Jones, Timm Faulwasser, Milan Korda

This paper investigates the relations between three different properties, which are of importance in optimal control problems: dissipativity of the underlying dynamics with respect to a specific supply rate, optimal operation at steady state, and the turnp ...

Towards Novel Researcher Tooling Based on Multimodal Analytics

Maria Jesus Rodriguez Triana

Much of educational research today employs a complex mixture of qualitative and quantitative analyses, both during the exploratory and confirmatory phases. However, researchers are still stuck with tools that were developed mainly for single-perspective re ...

Satisficing measure approach for vehicle routing problem with time windows under uncertainty

Jingjing Jiang

The complexity of evaluating chance constraints makes chance-constrained programming problem difficult to solve. One way to handle this complexity is by devising satisficing measures for the relevant uncertainties. This paper focuses on solving the stochas ...

Fluid Driven Fractures – Modeling and realities

Brice Tanguy Alphonse Lecampion

In this talk, we will first review the physics and mechanics of fluid driven fractures with the aim of engineering hydraulic stimulation in practice. In particular, based on theoretical modeling and comparisons with experiments, we will clarify a number of ...

Dexterous Undersea Interventions with Far Distance Onshore Supervision: the DexROV Project

Sylvain Calinon, Ajay Kumar Tanwani

The operation of a ROV requires significant off-shore dedicated manpower to handle and operate the robotic platform. In order to reduce the burden of operations, DexROV proposes to work out more cost effective and time efficient ROV operations, where manne ...
