Optimal combinations of stochastic frontier and data envelopment analysis models

Benchmarking the Efficiency of Philippines Electric Cooperatives Using Stochastic Frontier Analysis and Data Envelopment Analysis

This paper attempts to determine alternative methods of benchmarking the efficiency of electric companies to aid the regulator in crafting policies in enticing them to pursue more efficient production. This paper utilizes the data of electric cooperatives (ECs) in the Philippines, the one in charge of missionary electrification yet the smallest and most heavily indebted part of distribution sec...

Generalized Fuzzy Inverse Data envelopment Analysis Models

Traditional DEA models do not deal with imprecise data and assume that the data for all inputs and outputs are known exactly. Inverse DEA models can be used to estimate inputs for a DMU when some or all outputs and efficiency level of this DMU are increased or preserved. this paper studies the inverse DEA for fuzzy data. This paper proposes generalized inverse DEA in fuzzy data envelopment anal...

Alternative methods to examine hospital efficiency: data envelopment analysis and stochastic frontier analysis.

There has been increasing interest in the ability of different methods to rank efficient hospitals over their inefficient counterparts. The UK Department of Health has used three cost indices to benchmark NHS hospitals (Trusts). This study uses the same dataset and compares the efficiency rankings from the cost indices with those obtained using Data Envelopment Analysis (DEA) and Stochastic Fro...

Data Envelopment Analysis Models In The Presence Of Ratio Data and Non-Discretionary Factors

Efficiency of Centralized Structures in Data Envelopment Analysis Ratio Models

This paper investigates the centralized resource allocation with centralized structures by using the data envelopment analysis-ratio (DEA-R) models. To this end, it proposes a method to determine the resource allocation of centralized structures such that the ratio of inputs to outputs are minimized.
