this paper presents a data envelopment analysis (dea) model combined with bootstrapping to assess performance of one of the data mining algorithms. we applied a two-step process for performance productivity analysis of insurance branches within a case study. first, using a dea model, the study analyzes the productivity of eighteen decision-making units (dmus). using a malmquist index, dea deter...

abstract in the past few years, diversification has turned into a highly controversial issue amongst numerous managers in almost each and every business. it is contended by many that diversification is vitally important and highly effective especially when it comes to evaluating the financial performance. there are several studies about the relationship between diversification and financial per...

Based on a sample of about 600 state enterprises from 1980 to 1994, this paper investigates the productivity performance of SOEs using Data Envelopment Analysis and a Malmquist index. Our empirical results show that the average technical efficiency was low for these firms. Considerable productivity growth was found, but it was accomplished mainly through technical progress rather than through e...

The Trade Offs approach is an advanced tool for the improvement of the discrimination of Data Envelopment Analysis (DEA) models, Meta Malmquist Index was defined by Maria Portella and et. al (2008). In this paper we compute the Meta Malmquist Index in Trade Offs model in DEA and we compare, obtaining results, of Meta Malmquist Index in different models of DEA, Variable Return to Scale (VRS), Co...

Multi-period differences of technical and financial performances are analyzed by comparing five North African railways over the period 1990–2004. A first approach is based on Malmquist DEA TFP index for measuring total factors productivity change, decomposed into efficiency change technological changes. multiple criteria analysis also performed using PROMETHEE II method ARGOS software. These me...

The total factor productivity (TFP) of a multiple-output multiple-input firm can be defined as the ratio of an aggregate output to an aggregate input. With this definition, index numbers that measure changes in TFP can be expressed as the ratio of an output quantity index to an input quantity index. This paper uses the term multiplicatively complete to describe TFP index numbers that are constr...

although economic and managerial literature is replete with studies that probe about productivity but only a few studies decompose it to its components (technological changes, managerial efficiency changes and scale efficiency changes)and analysis their share in productivity changes (positively or negatively). accordingly, this article attempts to explain the issue by decompose productivity to ...
