Combined Method of Efficiency and Super efficiency on Slacks-BasedMeasure in Additive Data Envelopment Analysis

Tone [۱۰] proposed a method of super-efficiency slack-based measures (SBM) for ranking efficientdecision-making units (DMUs), so that this model would rank efficient DMUs. Inefficient decisionmakingunits have not been able to rank. The established model was able to measure radially. It calculatesand measuring the efficiency of inefficient DMUs and the amount of super-efficiency of efficient DMUs.Du et al. [۵] developed the Charens et al. [۴] model into the additive DEA model, as well as the additivesuper performance model. Turn et al. [۱۱] used a linear SBM and S-SBM integrated model that had theproperties of both models and reduced the time factor compared to previous models. In order to be able tocalculate the amount of additive super efficiency; First we identify the efficient DMUs and then apply theadditive super-efficiency model to the efficient DMUs. In this paper, the proposed model obtains theadditive efficiency value of inefficient DMUs and the additive super efficiency value of efficient DMUswith less computation time. The amount of efficiency and super-efficiency of the DMUs calculated fromthe integrated model in this article can be compared to the Guo [۷] article in comparison with the timetable of the text of the article.
