Optimal Budget Allocation for Sample Average Approximation

Operations Research, 2013
The sample average approximation approach to solving stochastic programs induces a sampling error, caused by replacing an expectation by a sample average, as well as an optimization error due to approximating the solution of the resulting sample average problem.

Joint Chance-Constrained Economic Dispatch Involving Joint Optimization of Frequency-Related Inverter Control and Regulation Reserve Allocation

CSEE Journal of Power and Energy Systems
The issues of uncertainty and frequency security become significantly serious in power systems with the high penetration of volatile inverter-based renewables (IBRs), which makes it necessary to consider the uncertainty and frequency-related constraints ...

A Sample Average Approximation Approach for Aircraft Product Configuration Optimization with Customer Order Uncertainty

Aerospace
Commercial aircraft manufacturers often face order uncertainty in particular situations, such as quantity or demand change, or lack of confirmed customer options. As a countermeasure, aircraft manufacturers can adopt a two-stage strategy to produce batch

General Feasibility Bounds for Sample Average Approximation via Vapnik--Chervonenkis Dimension

SIAM Journal on Optimization, 2022
We investigate the feasibility of sample average approximation (SAA) for general stochastic optimization problems, including two-stage stochastic programming without the relatively complete recourse assumption. Instead of analyzing problems with specific structures, we utilize results from the Vapnik-Chervonenkis (VC) dimension and Probably ...

Imaging of High‐Risk Neuroblastoma: Recommendations From SIOPEN Radiology and Nuclear Medicine Specialty Committees

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Neuroblastoma is the most common extracranial solid tumor in early childhood. Its clinical behavior is highly variable, ranging from spontaneous regression to fatal outcome despite intensive treatment. The International Society of Pediatric Oncology Europe Neuroblastoma Group (SIOPEN) Radiology and Nuclear Medicine Specialty Committees ...

Results of the Childhood Cancer and Leukaemia Group's United Kingdom Relapsed Wilms Tumour Trial

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background The United Kingdom relapsed Wilms tumour (UKW‐R) trial aimed to improve the historically low survival rates after relapse of Wilms tumour (WT) through a prospective national risk‐stratified protocol. The trial also evaluated efficacy and toxicity of high‐dose melphalan.

Sample average approximation of stochastic dominance constrained programs [PDF]

Mathematical Programming, 2010
The paper develops an algorithm for the solution of optimization problems with multi-variate second-order stochastic dominance constraints. The sample Average Approximation (SAA) method is applied to a relaxation of this problem. For the resulting semi-infinite program, asymptotic convergence of optimal values and optimal solutions (as the sample size ...

Parent Quality of Life at Two Years Following Their Child's Completion of Acute Lymphoblastic Leukemia Treatment

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Parents of children treated for acute lymphoblastic leukemia (ALL) often experience significant caregiver burden and disruption to their well‐being. While parent quality of life (QoL) during treatment is well characterized, little is known about outcomes during early survivorship.
