Decision-dependent probabilities in stochastic programs with recourse
Hellemo, Lars; Barton, Paul I.; Tomasgard, Asgeir (Journal article; Peer reviewed, 2018)Stochastic programming with recourse usually assumes uncertainty to be exogenous. Our work presents modelling and application of decision-dependent uncertainty in mathematical programming including a taxonomy of stochastic ... -
Generalized sensitivity analysis of nonlinear programs using a sequence of quadratic programs
Stechlinski, Peter; Jaeschke, Johannes; Barton, Paul I. (Journal article; Peer reviewed, 2018)Local sensitivity information is obtained for KKT points of parametric NLPs that may exhibit active set changes under parametric perturbations; under appropriate regularity conditions, computationally relevant generalized ... -
Global optimization of a hybrid waste tire and natural gas feedstock polygeneration system
Rammohan Subramanian, Avinash Shankar; Gundersen, Truls; Barton, Paul I.; Adams, Thomas A. (Peer reviewed; Journal article, 2022)The globally optimal design and operation of a process that converts a hybrid waste tire and natural gas feedstock to multiple products (such as electricity, methanol, dimethyl ether, olefins, and liquefied natural gas) ... -
Implementation and evaluation of a new solution approach for semidefinite programming
Lund, Marlene Louise (Master thesis, 2017)The main objective of this thesis was to perform initial studies on a new approach for solving semidefinite programs. In this solution method, a nonsmooth representation of the optimality conditions of semidefinite programs ... -
Optimization under uncertainty of a hybrid waste tire and natural gas feedstock flexible polygeneration system using a decomposition algorithm
Rammohan Subramanian, Avinash Shankar; Kannan, Rohit; Holtorf, Flemming; Adams, Thomas Alan; Gundersen, Truls; Barton, Paul I. (Peer reviewed; Journal article, 2023)Market uncertainties motivate the development of flexible polygeneration systems that are able to adjust operating conditions to favor production of the most profitable product portfolio. However, this operational flexibility ... -
Simulation of a Dual Mixed Refrigerant Process using i Nonsmooth Framework
Vikse, Matias; Watson, Harry A.J.; Barton, Paul I.; Gundersen, Truls (Journal article; Peer reviewed, 2018)Natural gas liquefaction is an energy intensive process with very small driving forces at cryogenic temperatures. Small temperature differences arise from the excessive exergy destruction that occurs from irreversible heat ... -
Simulation of dual mixed refrigerant natural gas liquefaction processes using a nonsmooth framework
Vikse, Matias; Watson, Harry AJ; Gundersen, Truls; Barton, Paul I. (Journal article; Peer reviewed, 2018)Natural gas liquefaction is an energy intensive process where the feed is cooled from ambient temperature down to cryogenic temperatures. Different liquefaction cycles exist depending on the application, with dual mixed ...
