Extended cross decomposition for mixed-integer linear programs with strong and weak linking constraints
(Elsevier BV, 2018-11-02)
Large-scale mixed-integer linear programming (MILP) problems, such as those from two-stage stochastic programming, usually have a decomposable structure that can be exploited to design efficient optimization methods. ...
A joint decomposition method for global optimization of multiscenario nonconvex mixed-integer nonlinear programs
(Springer Science and Business Media LLC, 2019-11-01)
This paper proposes a joint decomposition method that combines Lagrangian decomposition and generalized Benders decomposition, to efficiently solve multiscenario nonconvex mixed-integer nonlinear programming (MINLP) problems ...
A new cross decomposition method for stochastic mixed-integer linear programming
(Elsevier BV, 2017-01-16)
Two-stage stochastic mixed-integer linear programming (MILP) problems can arise naturally from a variety of process design and operation problems. These problems, with a scenario based formulation, lead to large-scale MILPs ...
A new optimization model and a customized solution method for natural gas production network design and operation
This article proposes to tackle integrated design and operation of natural gas production networks under uncertainty, using a new two-stage stochastic programming model, a novel reformulation strategy, and a customized ...
A multi-commodity flow formulation for the optimal design of wastewater treatment networks
(Elsevier BV, 2020-03-04)
The wastewater treatment network (WWTN) optimization problem can be viewed as an extension of the generalized pooling problem (GPP), where not only the different streams are mixed and split, but also some chemical components ...
Optimal Utilization of Natural Gas Pipeline Storage Capacity Under Future Supply Uncertainty
The ability of pipelines to store gas by increasing their operating pressure, or linepacking, is a common operational practice used to mitigate future operational uncertainty. The optimal operation of a gas pipeline network ...
