Transmission network expansion planning considering uncertainty in generation and demand
(2008-12-01)
This paper presents a mathematical model and a methodology to solve a transmission network expansion planning problem considering uncertainty in demand and generation. The methodology used to solve the problem, finds the ...
A note on model uncertainty in linear regression
(Blackwell Publ Ltd, 2003-01-01)
We consider model selection uncertainty in linear regression. We study theoretically and by simulation the approach of Buckland and co-workers, who proposed estimating a parameter common to all models under study by taking ...
Smiling in the rain: Seven reasons to be positive about uncertainty in hydrological modelling
(Processes Hydrological Processes Vol. 27(7): 1117–1122, 2012-03-30)
Over 20 years ago, the notion of ‘positive uncertainty’ was introduced in the field of psychology (Gelatt, 1989). This was coincident to some developments in the hydrological sciences (e.g. Beven and Binley, 1992; Grayson ...
Uncertainty in a monthly water balance model using the generalized likelihood uncertainty estimation methodology
(2015)
Hydrological models are simplified representations of natural processes and subject to errors. Uncertainty bounds are a commonly used way to assess the impact of an input or model architecture uncertainty in model outputs. ...
Modelling and uncertainties characterization for robust control
(Elsevier Sci Ltd, 2013-02)
In this work, multi-input multi-output (MIMO) process identification is studied, where the model identification is dedicated to the control design goal. An ad hoc identification procedure is presented which allows estimating ...
Model-based run-to-run optimization under uncertainty of biodiesel production
(Elsevier, 2013-06)
A significant source of uncertainty in biodiesel production is the variability of feed composition since the percentage and type of triglycerides varies considerably across different raw materials. Also, due to the complexity ...
On the robustness of structural risk optimization with respect to epistemic uncertainties.
(Redding, 2012)
In the context of structural design, risk optimization allows one to find a proper point of balance between the concurrent goals of economy and safety. Risk optimization involves the minimization of total expected costs, ...
Transmission network expansion planning considering uncertainty in demand
(Institute of Electrical and Electronics Engineers (IEEE), 2006-11-01)
This paper presents two mathematical models and one methodology to solve a transmission network expansion planning problem considering uncertainty in demand. The first model analyzed the uncertainty in the system as a ...
Fuzzy rule-based system for evaluation of uncertainty transaction in cassava Chain
(2015-01-01)
A fuzzy ruled-based system was developed in this study and resulted in an index indicating the level of uncertainty related to commercial transactions between cassava growers and their dealers. The fuzzy system was developed ...
