Journal ArticleDOI
An agent-based modeling approach to predict the evolution of market share of electric vehicles: A case study from Iceland
Ehsan Shafiei,Hedinn Thorkelsson,Eyjolfur Ingi Asgeirsson,Brynhildur Davidsdottir,Marco Raberto,Hlynur Stefansson +5 more
TL;DR: In this article, an agent-based model is developed to study the market share evolution of passenger vehicles in Iceland, a country rich in domestic renewable energy, taking into account internal combustion engine (ICE) vehicles that are currently dominant in the market and electric vehicles (EVs) that are likely to enter the market in the future.
Journal ArticleDOI
Energy, economic, and mitigation cost implications of transition toward a carbon-neutral transport sector: A simulation-based comparison between hydrogen and electricity
Ehsan Shafiei,Brynhildur Davidsdottir,Jonathan Leaver,Hlynur Stefansson,Eyjolfur Ingi Asgeirsson +4 more
TL;DR: In this paper, a simulation-based comparative analysis of hydrogen and electricity transitional pathways to a near carbon-neutral transport sector in Iceland is presented, which assumes an accelerated transition toward hydrogen and electric vehicles through stringent policies banning petroleum fuel vehicles from 2035.
Journal ArticleDOI
Comparative analysis of hydrogen, biofuels and electricity transitional pathways to sustainable transport in a renewable-based energy system
Ehsan Shafiei,Brynhildur Davidsdottir,Jonathan Leaver,Hlynur Stefansson,Eyjolfur Ingi Asgeirsson +4 more
TL;DR: In this paper, a comparative analysis of electric, hydrogen and biofuel transitional pathways to a future sustainable road transport in Iceland, a country with a renewable-based energy system, is presented.
Journal ArticleDOI
Integrated Agent-based and System Dynamics Modelling for Simulation of Sustainable Mobility
Ehsan Shafiei,Hlynur Stefansson,Eyjolfur Ingi Asgeirsson,Brynhildur Davidsdottir,Marco Raberto +4 more
TL;DR: In this paper, a conceptual framework for a comprehensive evaluation of the diffusion process of alternative fuel vehicles is introduced, which takes into account the most influencing stakeholders, including car manufacturers, car dealers, consumers, energy supply system, fuel stations and government.
Journal ArticleDOI
Discrete and continuous time representations and mathematical models for large production scheduling problems: A case study from the pharmaceutical industry
TL;DR: This paper decomposes the problem into two parts and compares discrete and continuous time representations for solving the individual parts and shows pros and cons of each model.
