Dynamic DEA: A slacks-based measure approach

In data envelopment analysis, there are several methods for measuring efficiency change over time, e.g. the window analysis and the Malmquist index. However, they usually neglect carry-over activities between consecutive two terms. These carry-overs play an important role in measuring the efficiency of decision making units in each term as well as over the whole terms based on the long-term vie...

Network DEA: A slacks-based measure approach

Traditional DEA models deal with measurements of relative efficiency of DMUs regarding multiple-inputs vs. multiple-outputs. One of the drawbacks of these models is the neglect of intermediate products or linking activities. After pointing out needs for inclusion of them in DEA models, we propose a slacks-based network DEA model that can deal with intermediate products. Using this model we can ...

Does international trade improve environmental efficiency? An application of a super slacks-based measure of efficiency

This study analyzes the impact of international trade on environmental efficiency. Using a data envelopment analysis (DEA) model that allows us to treat undesirable outputs and super-efficiency beyond unity, we measure the environmental efficiency of four typical air pollutants—SO2, NOx, particulate matter 10 μm or less in diameter, and CO2—for 98 countries for the period 1970–2008. The resulti...

A slacks-based measure of efficiency in data envelopment analysis

In this paper, we will propose a Slacks-Based measure (SBM) of efficiency in DEA. This scalar measure deals directly with the input surplus and the output shortage of the decision making unit (DMU) concerned. It is unit invariant and monotone decreasing with respect to input surplus and output shortage. Furthermore, this measure is decided only by consulting with the reference set of the DMU an...

A modified slacks-based measure model for data envelopment analysis with 'natural' negative outputs and inputs

This paper is concerned with Data Envelopment Analysis of systems with Natural Negative Inputs, and Natural Negative Outputs, i.e. inputs and outputs that, by their nature less than zero. Examples of situations with only positive inputs and positive and natural negative outputs are given and of situations in which both natural negative inputs and natural negative outputs occur. More attention h...
