Efficiency of DMUs in Presence of New Inputs and Outputs in DEA
Examining the impacts of data modification is considered as sensitivity analysis. A lot of studies have considered the data modification of inputs and outputs in DEA. The issues which has not heretofore been considered in DEA sensitivity analysis is modification in the number of inputs and (or) outputs and determining the impacts of this modification in the status of efficiency of DMUs. This pa...
متن کاملRanking DMUs by Comparing DEA Cross-Efficiency Intervals Using Entropy Measures
Cross-efficiency evaluation, an extension of data envelopment analysis (DEA), can eliminate unrealistic weighing schemes and provide a ranking for decision making units (DMUs). In the literature, the determination of input and output weights uniquely receives more attentions. However, the problem of choosing the aggressive (minimal) or benevolent (maximal) formulation for decision-making might ...
متن کاملStability of RTS of Efficient DMUs in DEA with Fuzzy
An important property of production functions is the concept return to scale (RTS) as found in the literature. There are two common variations RTS in data envelopment analysis (DEA) used, constant return to scale (CRS) and variation return to scale (VRS). The envelopment surface in BCC model is VRS and this is the result of the presence of the convexity constraint in the dual model and, equival...
متن کاملassessment of the efficiency of s.p.g.c refineries using network dea
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
A DEA with Categorical DMUs Based Model in Profit Sharing
Submitted: Jun 12, 2013; Accepted: Jul 23, 2013; Published: Jul 25, 2013 Abstract: Companies around the world normally assign a portion of their benefits to their employees. This policy is used as an encouragement to increase the motivation of employees. If the profit sharing seems unfair, its expected results will be lost. In this paper, a model is developed to determine a desirable profit sha...
