SMEs challenges and needs in relation to innovation agendas and strategies
(Chapter; Bokkapittel; Conference object; Konferansebidrag, 2016-06-21)
Regional research project are, as is also regional industry, highly need-based. That is, understanding the stakeholders’ (or customers’) real challenges and related needs is important. This study is based on interviews with SMEs in the Northern parts of Finland, Norway and Sweden, but also on available innovation agendas and strategies for each country. The differences among the companies in those ...
A stochastic programming approach with improved multi-criteria scenario-based solution method for sustainable reverse logistics design of Waste electrical and electronic equipment (WEEE)
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-12-17)
Today, the increased public concern for sustainable development and more stringent environmental regulations have become the most important driving forces for value recovery from end-of-life and end-of use products through reverse logistics. Waste electrical and electronic equipment (WEEE) contains both valuable components that need to be recycled and hazardous substances that have to be properly ...
A general reverse logistics network design model for product reuse and recycling with environmental considerations
(Peer reviewed, 2016-04-02)
Reverse logistics is believed to be one of the most promising solutions for capturing the remaining values from used products and has been extensively focused by both academics and practitioners during the past two decades. Conceptual framework, mathematical programming and computational algorithms have been developed for decision making at strategic, tactical and operational levels of a reverse ...
An improved multi-objective programming with augmented ε-constraint method for hazardous waste location-routing problem
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-05-31)
Hazardous waste location-routing problems are of importance due to the potential risk for nearby residents and the environment. In this paper, an improved mathematical formulation is developed based upon a multi-objective mixed integer programming approach. The model aims at assisting decision makers in selecting locations for different facilities including treatment plants, recycling plants and ...
Resolvent bounds for jump generators
(Journal article; Peer reviewed; Tidsskriftartikkel, 2016-12-02)
The paper deals with jump generators with a convolution kernel. Assuming that the kernel decays either exponentially or polynomially, we prove a number of lower and upper bounds for the resolvent of such operators. In particular we focus on sharp estimates of the resolvent kernel for small values of the spectral parameter. We consider two applications of these results. First we obtain pointwise ...
Review of marine icing and anti-/de-icing systems
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-08-17)
The aim of this work is to review the phenomenon of icing in marine operations. The focus is on two main sources of icing, namely atmospheric and sea spray. The literature reveals that sea spray icing is the main contributor to marine icing. This work discusses the available ice accretion prediction models on ships and offshore structures. It also reviews the anti-/de-icing technologies that can be ...
