Improving the Decision-making of Reverse Logistics Network Design Part I: A MILP Model under Stochastic Environment
(Peer reviewed; Bokkapittel; Book; Bok; Chapter, 2018-02-11)
The study of the network design problems related to reverse supply chain and reverse logistics is of great interest for both academicians and practitioners due to its important role for a sustainable society. However, reverse logistics network design is a complex decision-making problem that involves several interactive factors and faces many uncertainties. Thus, in order to improve the reverse ...
A Literature Review on Technologies in Future Small-scale Intelligent Manufacturing Systems
(Peer reviewed; Chapter; Bokkapittel, 2018-02-05)
Emergence of global markets forces businesses to become more flexible and adaptive to constantly changing demands and environments. In order to do so, enterprises turn towards application of newest technologies in manufacturing in order to make them intelligent. Since Small and Medium Enterprises play the central role in the domain of European manufacturing, the question arises – based on their ...
Improving the Decision-making of Reverse Logistics Network Design Part II: An Improved Scenario-based Solution Method and Numerical Experimentation
(Peer reviewed; Chapter; Bokkapittel, 2018-02-11)
The study of the network design problems related to reverse supply chain and reverse logistics is of great interest for both academicians and practitioners due to its important role for a sustainable society. However, reverse logistics network design is a complex decision-making problem that involves several interactive factors and faces many uncertainties. Thus, in order to improve the reverse ...
A Trade-off Model for Green Supply Chain Design: An Efficiency-versus-Emission Analysis
(Peer reviewed; Chapter; Bokkapittel, 2018-04-09)
—With the growing concern of climate change and global warming, the reduction on carbon emissions of supply chain activities have been increasingly focused by both academics and corporates in the last two decades. The increased public awareness on sustainability and stricter environmental policies together enforce the companies to rethink their practices in supply chain design and operations in an ...
Predicting Bedside Falls using Current Context
(Peer reviewed; Chapter; Bokkapittel, 2018-02-05)
Each year about a third of the elderly aged 65 or older experience a fall. Many of these falls could be avoided if fall risk assessment and prevention tools where available in the daily living situation. Such tools would need to use the current context as input to predict an imminent fall. This paper presents an approach predicting imminent falls using data from a roof-mounted infrared array combined ...
A Reliable Modular Based PV-Battery Hybrid System with Peak Shaving Capability
(Peer reviewed; Chapter, 2018)
The driving factors in emerging photovoltaic (PV) systems and battery-energy-storage systems (BESS) are highly scalable feature, modular and flexible structures with superior transformerless performance. The feasibility of Modular Multilevel Converter (MMC) to operate without overall DC-link allows the integration of PV generators and battery strings with its submodules (SMs), whereas each SM acts ...
Digitalization of the power business: How to make this work?
(Peer reviewed; Bokkapittel; Book; Bok; Chapter, 2018)
As a result of the digitalization of the power business in Norway and Europa, a lot of new possibilities and challenges arise. In 2014 an expert committee one outlined a proposal for the future grid company structure in Norway (Reiten, 2014). In addition, new technologies are being implemented in the system. Wind power, solar power, un-regulated small hydro power production, battery storage domestic ...
Fuel cell technology application for Dubai rail systems
(Peer reviewed; Chapter, 2018-06-11)
Heat engines, such as internal combustion engines, have significant adverse effects on the environment due to their heat and harmful emissions. In addition, they are dependent on energy from fossil resources, which are depleting rapidly and they are not being properly utilized due to the relatively low efficiency of heat engines usually expressed by Carnot's efficiency. The low temperature direct ...
Location-based analysis and optimization of service network performance: A case study
(Peer reviewed; Book; Chapter, 2018-05-07)
The location problem of service network has been extensively focused by researchers in operational research due to the difficulty in balancing the level of service and efficiency. On the one hand, installing a large number of service facilities within the service network improves availability and responsiveness to customer demands, but it also increases the investment and operating cost. While on ...
Framework for Modeling and Simulation of Household Appliances
(Peer reviewed; Book; Chapter, 2018-12-31)
This paper describes a framework for simulating household appliances in Simulink. Typical Norwegian household equipment have been analyzed based on their characteristic behavior, to establish the requirement for synthesizing and recreating their current waveform, harmonic currents and phase shift. Both detailed simulation of the current waveform and RMS currents for simulation over longer time periods ...
