A Dea Model For Measuring The Relative Eeficiency Of Highway Maintenance Patrols

Extended secondary goal models for weights selection in DEA cross-efficiency evaluation

“…One more method for addressing the problem is the DEA common-weight evaluation method. Cook, Roll, and Kazakov (1990) and Roll, Cook, and Golany (1991) firstly proposed to use common weights for efficiency evaluation in DEA in the application background of performance evaluation and ranking of highway maintenance units. Further work on DEA common-weight evaluation can be seen in Kao and Hung (2005); Zohrehbandian et al (2010);and Sun et al (2013).…”

A systematic procedure to obtain a preferable and robust ranking of units

“…An interesting approach for us to obtain the ranking of units in the DEA structure is to apply the common weights to all DMUs. The use of common weights in DEA was first proposed by Cook et al [11] and Roll et al [12] to evaluate highway maintenance units. Cook et al [13,14] gave a subjective ordinal preference ranking with common weights obtained by closing the gap between the upper and lower limits of the weights while they proceed a series of bounded DEA runs.…”

A Revised Model of the Neutral DEA Model and Its Extension

“…This nonuniqueness of input and output weights would damage the use of cross-efficiency evaluation. To solve this problem, one solution suggested by Sexton et al [8] is to introduce a secondary goal to gain a unique set of the input and output weights among the multiple optimal solutions determined by the CCR-efficiency model (3). The most commonly used secondary goal functions were suggested by Doyle and Green [9] and are shown below:…”

“…One such method is DEA super efficiency model [2] that will lead to the efficiency value of efficient DMUs to be larger than 1, which will further distinguish the efficient DMUs. Another method is DEA common-weight evaluation [3]. Unlike the traditional DEA model in which each DMU uses its own favorable weights to measure the efficiency, the DEA common-weight evaluation adopts the common set of weights to measure the efficiency of all DMUs.…”
