The current paper proposes a slack-based version of the Super SBM, which is an alternative superefficiency model for the SBM proposed by Tone. Our two-stage approach provides the same superefficiency score as that obtained by the Super SBM model when the evaluated DMU is efficient and yields the same efficiency score as that obtained by the SBM model when the evaluated DMU is inefficient. The p...

We propose a bargaining process supergame over the strategies to play in a non-cooperative game. The agreement reached by players at the end of the bargaining process is the strategy profile that they will play in the original non-cooperative game. We analyze the subgame perfect equilibria of this supergame, and its implications on the original game. We discuss existence, uniqueness, and effici...

We consider the problem of enhancing the resolution of video through the addition of perceptually plausible high frequency information. Our approach is based on a learned data set of image patches capturing the relationship between the middle and high spatial frequency bands of natural images. By introducing an appropriate prior distribution over such patches we can ensure consistency of static...

Abstract In the framework of data envelopment analysis (DEA), Tone (Eur J Oper Res 130(3):498–509, 2001) introduced slacks-based measure (SBM) efficiency, which is a nonradial model that incorporates all slacks evaluated decision-making units (DMUs) into their efficiency scores, unlike classical radial models. Next, 143(1):32–41, 2002) developed SBM super-efficiency in order to differentiate an...

as regards of supper efficiency models which increased thediscrimination power of the standard dea models, still infeasibility mayoccure. in literature there exists some models overcome this difficulty.in this paper a new procedure has been mooted in order to remove thisshortcoming in a way that both input savings and output surplus arebeing considered. this procedure deals with nonradial chang...

the investigation of dimensional efficiency for branches of maskan bank in resources collection and facilities allocation: approach of super efficiency model with weight restrictions. the scarcity of financial resources of banks, especially in developing countries like as iran, leads to planning for improving efficiency and productivity. improving efficiency needs to performance measurement and...
