(Peer reviewed; Journal article, 2021)Choosing the right harvesting strategy is crucial for sustainable utilization of biological resources but is challenging in real systems with fluctuating environments. This challenge is expected to become even greater with ... -
Optimal harvesting in the presence of predation: An age-structured modelling approach
(Peer reviewed; Journal article, 2020)Predation of wildlife and livestock by large carnivores takes place within many ecological and institutional settings. In this paper, moose predation by wolves is studied within a Norwegian institutional setting where the ... -
Optimal harvesting of farmed salmon during harmful algal blooms
(Journal article; Peer reviewed, 2021)This paper studies the optimal harvesting decisions of a salmon farmer that faces the risk of harmful algal bloom as well as market uncertainty. The salmon farmer seeks to maximize the financial value of the fish farm by ... -
Optimal hedging strategies for salmon producers
(Journal article; Peer reviewed, 2018)We study the optimal hedging decisions for a risk-averse salmon producer. The hedging decisions are determined using a multistage stochastic programming model. The objective is to maximize the weighted sum of expected ... -
Optimal imperfect maintenance cost analysis of a two-component system with failure interactions
(Journal article; Peer reviewed, 2018)This paper considers a two-component system with failure interactions. Component 1 is repairable and component 2 is non repairable and is subject to an increasing degradation. One considers two different shock models. In ... -
Optimal integration of compression heat with regenerative steam Rankine cycles in oxy-combustion coal based power plants
(Journal article; Peer reviewed, 2015)The integration of process heat with regenerative steam Rankine cycles by preheating the boiler feedwater increases power generation from the steam turbines. In oxy-combustion coal based power plants, considerable compression ... -
Optimal investment decisions in lice-fighting technologies: A case study in Norway
(Journal article; Peer reviewed, 2019)The Norwegian salmon farming industry is currently facing significant obstacles to future growth. The major challenge is posed by the high level of sea lice in the sea nets at the salmon farms. At the moment both salmon ... -
Optimal investment in the energy system of Zero Emission Neighborhoods considering the refurbishment of the building stock
(Peer reviewed; Journal article, 2021)To increase the impact that Zero Emission Neighbourhoods (ZEN) can have in the effort to decrease CO2 emissions, the refurbishment of the existing building stock is a parameter that should be considered. The existing ... -
Optimal investment timing and capacity choice for pumped hydropower storage
(Journal article; Peer reviewed, 2014)Pumped hydropower storage can smooth output from intermittent renewable electricity generators and facilitate their large-scale use in energy systems. Germany has aggressive plans for wind power expansion, and pumped storage ... -
Optimal Linear Controller for Minimizing DC Voltage Oscillations in MMC-Based Offshore Multiterminal HVDC Grids
(Peer reviewed; Journal article, 2021)The paper aims at minimizing DC voltage oscillations in offshore multiterminal high-voltage direct current (HVDC) grids based on modular multilevel converters (MMCs). The DC voltage stability is a crucial factor in ... -
Optimal liquified natural gas (LNG) cold energy utilization in an Allam cycle power plant with carbon capture and storage
(Peer reviewed; Journal article, 2021)Oxy-combustion power cycles are an alternative technology for electricity generation to facilitate carbon capture and storage (CCS). Among oxy-combustion power cycles, the Allam cycle is one of the most promising technologies ... -
Optimal load management strategy for large electric vehicle charging stations with undersized charger clusters
