data envelopment analysis (dea) is a technique used to evaluate the relative efficiency of comparable decision making units (dmus) with multiple input-output. it computes a scalar measure of efficiency and discriminates between efficient and inefficient dmus. it can also provide reference units for inefficient dmus without consideration of the decision makers’ (dms) preferences. in this paper, ...

We present efficiency models to evaluate data warehouse operations and analyze a preliminary data set using one of the models. The macro model represents the efficiency of operating a collection of data warehouses for both refresh processing and query production over a monthly horizon. The micro models represent the efficiency of daily operations an individual data warehouse for either refresh ...

An economic measure of scale efficiency is the ratio of the minimum average cost to the average cost at the actual output level of a firm. It is easily measured by the ratio of the total cost of this output under the constant and variable returns to scale assumptions. This procedure does not identify the output level where the average cost reaches a minimum. This paper proposes a nonparametric ...

conclusions reduction of surplus production factors through comprehensive planning based on the results of the data envelopment analysis can play a major role in cost reduction of hospitals and health sectors. in hospitals with a technical efficiency score of less than one, the original and projected values of inputs were different; resulting in a surplus. hence, these hospitals should reduce t...
