It was originally produced by SDRC in 1982.I-DEAS was used primarily in the automotive industry, 1 most notably by Ford Motor Company (who standardized on the program 2 ) and by General Motors.SDRC was bought in 2001 by its competitor, Electronic Data Systems, which had also acquired UGS Corp.
Unigraphics). 1 EDS merged these two products into NX. UGS was purchased by Siemens AG in May 2007, and was renamed Siemens PLM Software. Current Practices.

I coded example 12 exactly as laid out in the tutorial my efficiencies results are exactly the same, but -- 1 my graphs seem to publish inefficient DMUs (red) as super-efficient (blue) instead 2 the second plot efficient DMUs vs times appearing in reference sets lists different DMUs for me vs what is in the worked example in the tutorial 3 my results file is a list of 15 instead of 11. In the 16th International Conference on Data Envelopment Analysis we presented deaR, a new R package for DEA. Now, it is a pleasure for me to announce that deaR is available to be installed and used. This package allows to run a wide variety of models based on DEA: Conventional DEA models: CCR, BCC, directional distance function multiplier, additive, non radial, sbm, radial super efficiency, additive super efficiency, sbm super efficiency, cross efficiency, bootstrapping, etc. You can get a brief introduction tutorial to install and use deaR (in English, Spanish, and Chinese) by clicking on the following link: deaR is not only oriented to research but also teaching. For that reason, deaR provides some datasets that come from articles already published. These datasets are used in the deaR function examples to replicate the results of the articles. We would really appreciate if you could spread the information about deaR among your colleagues and students. We will release a deaR shiny version (an interactive web app) son. Any comments and suggestions to improve deaR will be really appreciated. We also accept suggestions of DEA models to be considered for being programmed in new versions of deaR.
