Stochastic hydro-thermal unit commitment via multi-level scenario trees and bundle regularization
(Peer reviewed; Journal article, 2019)For an electric power mix subject to uncertainty, the stochastic unit-commitment problem finds short-term optimal generation schedules that satisfy several system-wide constraints. In regulated electricity markets, this ... -
Stochastic In-Port Routing in Chemical Shipping
(Master thesis, 2016)Chemical tankers spend a substantial amount of time in port as the development of port infrastructure has not followed the fast paced increase in the world fleet. The resulting traffic at terminals causes ships to wait for ... -
Stochastic investment model for offshore oil and gas production
(Master thesis, 2013)This report presents a stochastic multistage model that addresses strategic subsea separator investment decisions with reservoir uncertainty. Since strategic decisions in the petroleum industry have long-term consequences ... -
Stochastic local flexibility market design, bidding, and dispatch for distribution grid operations
(Journal article; Peer reviewed, 2022)In order to unlock the flexibility potential of energy consumers and prosumers, the development of market mechanisms for flexibility planning and procurement is necessary. The authors propose a stochastic local flexibility ... -
Stochastic master surgery scheduling
(Journal article; Peer reviewed, 2020)The aim of the Master Surgery Scheduling Problem (MSSP) is to schedule the medical specialties to the different operating rooms available, such that surgeries may be performed efficiently. We consider a MSSP where elective ... -
Stochastic Master Surgery Scheduling for the orthopaedic department at St. Olav's Hospital
(Master thesis, 2018)The regional health authority, Helse Midt-Norge (HMN), provides hospital services to the two counties Trøndelag and Møre og Romsdal. Forecasting estimates that the number of people living in these two counties that exceed ... -
Stochastic Mixed Integer Problems for Bidding in Sequential Electricity Markets - Scenariowise decomposition approaches
(Master thesis, 2016)With an increasing number of ancillary services and energy markets, the decision making process for a power producer is becoming more complex. This thesis investigates the bidding problem of a Norwegian hydropower producer ... -
Stochastic modeling of imperfect markets
(Chapter, 2017)Stochastic optimization approaches ignore that the decisions of different actors in markets typically do not lead to a system-wide optimal solution. Suppliers in markets with entrance barriers or other aspects that hinder ... -
Stochastic modelling of shortterm uncertainty in long-term energy models: Applied to TIMES models of Scandinavia
(Doctoral theses at NTNU;2017:316, Doctoral thesis, 2017)Summary of the thesis Long-term energy system models can be used to understand the complexity of the energy system and can thus provide reasonable insights to decision makers. In energy systems with a large share of ... -
A Stochastic MPEC Approach for Grid Tariff Design with Demand-Side Flexibility
(Peer reviewed; Journal article, 2020)As the end-users increasingly can provide fexibility to the power system, it is important to consider how this fexibility can be activated as a resource for the grid. Electricity network tarifs is one option that can be ... -
A stochastic MPEC approach for grid tariff design with demand‑side fexibility
(Peer reviewed; Journal article, 2023)As the end-users increasingly can provide flexibility to the power system, it is important to consider how this flexibility can be activated as a resource for the grid. Electricity network tariffs is one option that can ... -
Stochastic multistage bidding optimisation for a Nordic hydro power producer in the post-spot markets
(Master thesis, 2017)As a result of an increased focus on climate policy and renewable energy sources, the share of intermittent power in the Nordic power system is growing. With a less predictable production, the interest for trading on the ... -
Stochastic Multistage Bidding Optimisation in an Intraday Market with Limited Liquidity
(Chapter, 2018)This paper describes a multistage stochastic mixed integer programming problem for a hydro power producer that maximizes profit in the low liquid intraday market and balancing market. A comprehensive modelling framework ... -
Stochastic Network Design for Planning Scheduled Transportation Services: The Value of Deterministic Solutions
(Journal article; Peer reviewed, 2018)We study the value of deterministic solutions, in particular their quality and upgradability, in addressing stochastic network design problems, by analyzing their time-dependent formulations known as scheduled service ... -
Stochastic Network Design Modelling for Decarbonization of the Norwegian Freight Transportation System
(Master thesis, 2022)I denne masteroppgaven presenterer vi en model for dekarbonisering av det norske godstransportnettverket over tid. Problemet innebærer å allokere flyt av varer mellom norske fylker og utenlandske soner til ulike transportformer ... -
A stochastic optimization algorithm for the supply vessel planning problem under uncertain demand and uncertain weather conditions
(Journal article; Peer reviewed, 2023)The Supply Vessel Planning Problem (SVPP) with stochastic demands and uncertain weather conditions is a transportation problem occurring in offshore oil and gas logistics. A fleet of supply vessels based at an onshore depot ... -
A Stochastic Optimization Approach for Scheduling Surgeries in Parallel Operating Rooms
(Master thesis, 2016)The continuous production of reliable operating room (OR) schedules greatly influences the overall performance of surgery delivery systems in most hospitals. We develop a two-stage stochastic integer programming model that ... -
A stochastic policy algorithm for seasonal hydropower planning
(Journal article; Peer reviewed, 2023)Hydropower producers need to plan several months or years ahead to estimate the opportunity value of water stored in their reservoirs. The resulting large-scale optimization problem is computationally intensive, and model ... -
Stochastic Programming for Maritime Fleet Renewal Problems
(Doktoravhandlinger ved NTNU, 1503-8181; 2014:24, Doctoral thesis, 2014)The scope of this thesis is to develop knowledge and methods, based on mathematical programming, for the Maritime Fleet Renewal Problem (MFRP). The MFRP consists of finding the best modification of the current fleet of ... -
