The role of predictive uncertainty in the operational management of reservoirs [PDF]

open access: yesProceedings of the International Association of Hydrological Sciences, 2014
The present work deals with the operational management of multi-purpose reservoirs, whose optimisation-based rules are derived, in the planning phase, via deterministic (linear and nonlinear programming, dynamic programming, etc.) or via stochastic ...

A Stochastic Inexact Robust Model for Regional Energy System Management and Emission Reduction Potential Analysis—A Case Study of Zibo City, China

open access: yesEnergies, 2018
In this study, in order to improve regional energy system adjustment, a multistage stochastic inexact robust programming (MSIRP) is proposed for electric-power generation planning and structure adjustment management under uncertainty.

A comparison of four approaches from stochastic programming for large-scale unit-commitment

open access: yesEURO Journal on Computational Optimization, 2017
In energy management, the unit-commitment problem deals with computing the most cost-efficient production schedule that meets customer load, while satisfying the operational constraints of the units.

Robust Planning of Energy and Environment Systems through Introducing Traffic Sector with Cost Minimization and Emissions Abatement under Multiple Uncertainties

open access: yesApplied Sciences, 2019
Motor vehicles have been identified as a growing contributor to air pollution, such that analyzing the traffic policies on energy and environment systems (EES) has become a main concern for governments. This study developed a dual robust stochastic fuzzy

A multistage distributionally robust optimization approach for generation dispatch with demand response under endogenous and exogenous uncertainties

open access: yesIET Generation, Transmission & Distribution, 2023
Decision‐dependent (endogenous) uncertainties (DDUs), as a new type of uncertainties revealed recently, couple dispatch decisions with uncertainty parameters and thus render power system dispatch more challenging.

Robustness in stochastic programming models

open access: yesApplied Mathematical Modelling, 1993
A two-staged stochastic programming problem with simple recourse is considered. A robustness measure for such kind of problems is introduced. This two-staged problem is applied to the acid rain control.

A distributionally robust optimization approach for two-stage facility location problems

open access: yesEURO Journal on Computational Optimization, 2020
In this paper, we consider a facility location problem where customer demand constitutes considerable uncertainty, and where complete information on the distribution of the uncertainty is unavailable.

Robust Process Control by Dynamic Stochastic Programming [PDF]

open access: yesPAMM, 2004
AbstractUnnecessarily conservative behavior of standard process control techniques can be avoided by stochastic programming models when the distribution of random disturbances is known. In an earlier study we have investigated such an approach for tank level constraints of a distillation process.

An Integrated Problem of p-Hub Location and Revenue Management with Multiple Capacity Levels under Disruptions

open access: yesJournal of Advanced Transportation, 2019
This paper considers an integrated hub location and revenue management problem in which a set of capacities is available from which one can be chosen for each hub and the disruption is considered in a star-star shaped airline network.
