Modeling and mitigating supply chain disruptions as a bilevel network flow problem
Anna Timonina-Farkas, René Yves Glogg
Years of globalization, outsourcing and cost cutting have increased supply chain vulnerability calling for more effective risk mitigation strategies. In our research, we analyze supply chain disruptions in a production setting. Using a bilevel optimization ...
SPRINGER HEIDELBERG2022Optimal Matching of Random Parts
This paper examines the minimization of the cost for an expected random production output, given an assembly of finished goods from two random inputs, matched in two categories. We describe the optimal input portfolio, first using the standard normal appro ...
2022Exergy and exergoeconomic analyses of sustainable furfural production via reactive distillation
Lignocellulosic biomass is a potential renewable resource for production of high-value, sustainable products. Furfural is among the important bio-based chemicals in biorefineries. However, the conventional process of furfural production using a reaction-se ...
2021Optimization of MEW instrument components and their assembly
In recent years, a new additive manufacturing technology Melt Electrowriting (MEW) has become attractive, especially for biomedical applications, and it has potential in many other fields as well. In order to carry out an in-depth study of melt electrowrit ...
2021Performance Analysis of Ammonia in Solid Oxide Fuel Cells
Jan Van Herle, Suhas Nuggehalli Sampathkumar, Peter Hugh Middleton, Steve Joris
Ammonia (NH3) has 17.8 wt% hydrogen and is easily liquified at 25°C and 8 bar pressure. Ammonia is carbon-free and can be produced sustainably at large scale and low cost. Solid oxide fuel cells generate electricity with efficiencies greater than 60% and c ...
ECS2021Analysis of High Temperature Degradation of Alloys in Solid Oxide Fuel Cell
Solid oxide fuel cells (SOFCs) are approaching commercialization to improve power production efficiency. Currently, cost and lifetime reliability limit their spread in the market. The SOFC is ceramic-based, but refractory metal alloys are in fact the major ...
EPFL2019Robust multi-objective optimization of solid oxide fuel cell–gas turbine hybrid cycle and uncertainty analysis
François Maréchal, Shivom Sharma
Chemical process optimization problems often have multiple and conflicting objectives, such as capital cost, operating cost, production cost, profit, energy consumptions and environmental impacts. In such cases, Multi-Objective Optimization (MOO) is suitab ...
2018Exploring the interoperability of remote GPGPU virtualization using rCUDA and directive-based programming models
Directive-based programming models, such as OpenMP, OpenACC, and OmpSs, enable users to accelerate applications by using coprocessors with little effort. These devices offer significant computing power, but their use can introduce two problems: an increase ...
SPRINGER2018The Effects of Component Tolerances on the Thermo-Mechanical Reliability of SOFC Stacks
Jan Van Herle, Zacharie Wuillemin, Arata Nakajo, Fabio Greco
The reliability of solid oxide fuel cell (SOFC) systems is closing the gap to meet the requirements for market implementation. Finite-element (FE) stack models, typically used for stack reliability analyses, commonly consider idealized components. In reali ...
2017Dealing with fuel contaminants in biogas-fed solid oxide fuel cell (SOFC) and molten carbonate fuel cell (MCFC) plants: Degradation of catalytic and electro-catalytic active surfaces and related gas purification methods
Jan Van Herle, Hossein Madi, Davide Papurello
Fuel cell and hydrogen technologies are re-gaining momentum in a number of sectors including industrial, tertiary and residential ones. Integrated biogas fuel cell plants in wastewater treatment plants and other bioenergy recovery plants are nowadays on th ...
