Demand-based discrete optimization

We propose a methodological framework to include a wide variety of discrete choice models in (mixed) integer optimization problems. We succeed in obtaining a specification that is linear in the decision variables, allowing to use exact methods to solve the ...

Robust optimization for strategic energy planning

Michel Bierlaire, François Maréchal, Stefano Moret

Long-term planning for energy systems is often based on deterministic economic optimization and forecasts of fuel prices.When fuel price evolution is underestimated, the consequence is a low penetration of renewables and more efficient technologies in favo ...

Techno–economic design of hybrid electric vehicles and possibilities of the multi-objective optimization structure

François Maréchal, Zlatina Kirilova Dimitrova

The design criteria for modern sustainable development of vehicle powertrain are the high energy efficiency of the conversion system, the competitive cost and the lowest possible environmental impacts. In this article a multi-objective optimization methodo ...

Twin-shaped CFRP-sandwich pedestrian bridge

Thomas Keller

A concept of a nature-inspired pedestrian bridge which tries to merge architectural, structural and manufacturing aspects in an optimized way is presented. The 18.0-m-span bridge is designed as an overhead spatial frame of a complex double-curved shape, wh ...

When stakeholders cannot be involved in a modelling process: Integrating participatory modelling and consultative approaches

Franziska Meinherz

Diverse authors defend the idea that stakeholders’ involvement is of crucial importance in most decision-making processes. Adequate selection and involvement of the actors of a given social system is a key issue to increase understanding of the problem, an ...

Quantifying the time for accurate EEG decoding of single value-based decisions

Ricardo Andres Chavarriaga Lozano, Athina Tzovara

Background Recent neuroimaging studies suggest that value-based decision-making may rely on mechanisms of evidence accumulation. However no studies have explicitly investigated the time when single decisions are taken based on such an accumulation process. ...

Strategic energy planning for large-scale energy systems: A modelling framework to aid decision-making

François Maréchal, Daniel Favrat, Stefano Moret, Victor Codina Gironès

Concerns related to climate change and security of energy supply are pushing various countries to make strategic energy planning decisions. This requires the development of energy models to aid decision- making. Large scale energy models are often very com ...

Human and Machine Learning in Non-Markovian Decision Making

Michael Herzog, Aaron Michael Clarke, Elisa Tartaglia, Silvia Marchesotti, Walter Senn

Humans can learn under a wide variety of feedback conditions. Reinforcement learning (RL), where a series of rewarded decisions must be made, is a particularly important type of learning. Computational and behavioral studies of RL have focused mainly on Ma ...

Generalized Decision Rule Approximations for Stochastic Programming via Liftings

Daniel Kuhn, Wolfram Wiesemann

Stochastic programming provides a versatile framework for decision-making under uncertainty, but the resulting optimization problems can be computationally demanding. It has recently been shown that, primal and dual linear decision rule approximations can ...

Dynamic Information Acquisition

Thomas Alois Weber, Viet Anh Nguyen

We consider optimal information acquisition for the control of linear discrete-time random systems with noisy observations and apply the findings to the problem of dynamically implementing emissions-reduction targets. The optimal policy, which is provided ...

Graph Chatbot

Chattez avec Graph Search

Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
