The "trade-offs Data envelopment analysis (DEA)" model is built by adding an extra axiom to the traditional production possibility set. The axiom introduces some replacement relations as production rules between inputs and outputs and leads to some extensions to the production possibility set....

Evaluating group performance of decision-making units (DMUs) is an application of data envelopment analysis (DEA) and usually provides a measure to compare the frontiers of the production possibility sets (PPSs) corresponding to different groups and the internal inefficiencies of DMUs associated...

In many settings, systems are composed of a group of independent sub-units. Each sub-unit produces the same set of outputs by consuming the same set of inputs. Conventional data envelopment analysis (DEA) views such a system as a "black-box", and uses the sum of the respective inputs and outputs...

Data envelopment analysis (DEA) can be used for assessing the relative efficiency of a number of operating units, finding, for each unit, a target operating point lying on the strong efficient frontier. Most DEA models project an inefficient unit onto a most distant target, which makes its...

Precedent research based on data envelopment analysis (DEA) has been conducted to rank and benchmark the achievements of participating nations/regions in the Olympics, while this paper contributes to the Asian Games, with further concerns on two main issues, namely the common comparison basis...

When multiple outputs and multiple inputs are imprecise data such as bounded data, ordinal data or ratio bound data, the standard linear data envelopment analysis (DEA) model becomes a nonlinear and is called imprecise DEA (IDEA) which can either be converted into a linear program by scale...

This paper estimates and compares efficiency performance of 32 commercial banks in Vietnam during 2001–2005, as well as identifies possible factors determining such efficiency performance. Efficiency is measured by a data envelopment analysis (DEA) model and super-efficiency measure through a...

Opportunity costs of environmental regulations (OCER) are an important consideration when governments make decisions on the formulation of environmental policies and when plants make decisions in response to environmental policies. Aimed at measuring OCER, the current paper proposes an approach...

This paper reconciles diverse efficiency measures to characterize the operating performance of the National Innovation System (NIS) in 33 Asian and European countries. NIS efficiency rating should be considered as a key element for achieving greater innovation and competitive advantages. This...
