Data envelopment analysis (DEA) has been recently employed for performance and efficiency evaluation of decision-making units (DMUs) with multiple inputs outputs. Complex internal relations within a DMU required more accurate DEA models than existing classic DEA. In real world applications, shared resources, among stages supply chain, is great interest managers decision makers. Unfair allotment...

Diethanolamine (DEA) is a widely used ingredient in many consumer products and in a number of industrial applications. It has been previously reported that dermal administration of DEA to mice diminished hepatic stores of choline and altered brain development in the fetus. The aim of this study was to use mouse neural precursor cells in vitro to assess the mechanism underlying the effects of DE...

In this paper, we analyse economic development and growth through traditional measures (gross domestic product and human development index) and Data Envelopment Analysis (DEA) in Colombian departments over the period 1993e2007. We use a DEA model to measure and rank economic development and growth from different approaches such as poverty, equality and security. The results show considerable va...

This paper’s goal is twofold: it aims to assess the performance of 58 Iberian banks and explore relationship between such banks’ Intellectual Capital (IC) efficiency during a post-crisis period. As long as authors are aware, there gap in literature exploring global IC efficiency. First, Data Envelopment Analysis model was adopted measure rank them according their performance. were collected dig...

The deprotonation kinetics of the DEA--C02 and the DIPA-COZ zwitterions have been studied in aqueous blends of an&es at 298 K. Amine mixtures investigated were: DEA-TEA, DEA-MDEA. DEL-DMMEA, DEA-DEMEA, DIPA-TEA, DIPA-MDEA, DIPA-DMME~ DIPA-DEMEA. FOG each blend the zwitterion deprotonation constant of the additonal base present in solution (i.e. the tertiary amine) was determined. The observed d...

Data envelopment analysis (DEA) is a method frequently used to evaluate relative firm performance. However, high values in a few indicators can lead to a company being regarded as ‘efficient’, despite valuing poorly in other essential indicators. The Inefficiency Countervailed DEA (IC-DEA) method is thus developed. The method first defines an inefficient frontier using the proposed Reverse DEA ...

Port is an important node in logistics system. Aiming at lack of calculating and analysis for comprehensive efficiency in Port Logistics research, we bring DEA two-stage relative evaluation into this paper, and get production efficiency value and X-efficiency value. Based on these values, a formula for comprehensive efficiency measurement is proposed. Finally, this paper uses this model in maki...
