An application of the two-stage, semi-parametric approach with double bootstrap to analyze technical efficiency of Critical Access Hospitals

Nedelea, I. Cristian; Fannin, James Matthew - 2011

This study examines technical efficiency of Critical Access Hospitals (CAH) using a two-stage approach and bootstrap … second stage, efficiency scores are regressed on environmental variables using a truncated regression with bootstrap …. Alternatively, a double bootstrap procedure is used, where bias-corrected DEA efficiency scores, obtained by means of bootstrap in …

Linear Regression Model of the Conveyor Type Transport System

Pihnastyi, Oleh; Khodusov, Valery; Subbotin, Sergey - 2020

This article discusses the prospects of using linear regression models to describe multi-section branched transport systems of conveyor type. A characteristic feature of the functioning of a multi-section transport system is the presence of resonant peak values for the flow parameters of the...

Using PDE-model and system dynamics model for describing multi-operation production lines

Pihnastyi, Oleh; Yemelianova, Daria; Lysytsia, Dmytro - 2020

Two classes of models for describing production flow lines are analyzed. The use of models of these classes for the design of highly efficient control systems of production lines, the technological route of which consists of a large number of technological operations, is analyzed. The division...

The stabilization problem the flow parameters of the production line

Pihnastyi, Oleh; Khodusov, Valery - 2020

The problem of designing a system for optimal control of random deviations of flow parameters of a production line from the planned value is considered. The PDE-model of the production line was used as a foundation for the development of an algorithm for optimal control of the parameters...

Evaluating alternative estimators for optimal order quantities in the newsvendor model with skewed demand

Halkos, George; Kevork, Ilias - 2012

This paper considers the classical Newsvendor model, also known as the Newsboy problem, with the demand to be fully observed and to follow in successive inventory cycles one of the Exponential, Rayleigh, and Log-Normal distributions. For each distribution, appropriate estimators for the optimal...

Validity and precision of estimates in the classical newsvendor model with exponential and rayleigh demand

Halkos, George; Kevork, Ilias - 2012

In this paper we consider the classical newsvendor model with profit maximization. When demand is fully observed in each period and follows either the Rayleigh or the exponential distribution, appropriate estimators for the optimal order quantity and the maximum expected profit are established...
