The latest release of version 14 is 14d, with a new feature SBM Bounded Model as an extention to SBM Max of version 13, which replaced SBM Variation model of
version 12. In the real world, there are cases where input resources and/od output expansion are restricted by external constraints.
SBM Bounded Model takes care of such situations, so that the outcome of SBM Bounded Model becomes more realistic than before.
Note that these SBM models essentially represent KAIZEN improvement.
For more details, go to newsletter 17.
The final release of version 13 is 13g, with a new feature super SBM Max model. Earlier SBM model replaces SBM Variation model of version 12.
The SBM models usually report the worst efficiency scores for inefficient DMUS, i.e. the projected point is the farthest one on the associated
ewfficient frontier. In contrast, SBM Max models look for the nearest point on the efficient frontier, so that one can attain an efficient status by
minimum input resources and output expansion. For more details, go to newsletter 15
and newsletter 16.
The final release for version 12 is 12i, which repairs minor problems of the CCR model. In the release 12e, we introduced a new feature,
called SBM Variations, by which you can find the nearest point on the associated efficient frontier by maximizing the efficiency score.
For more details, go to newsletter 14.
Note that in Version 12, we also added a feature, Directional Distance Model, which computes the efficiency of
DMUs along the given direction of DMU. We offer two types of efficiency calculations, i.e. the ordinary one and the super efficiency. This is an innovative
extension of Radial Models (CCR and BCC), which had limited orientations of input and output. For detailed discussion on this model,
take a look at Newsletter 13.
With Version 11, we added a feature, called Resampling DEA, which deals with data variations and gives confidence intervals
of DEA scores. Also we introduced Fisher statistics in version 11.1, which enhance resampling accuracy (Note the number of
DMU has to be at least 4 to use Fisher statistics). Input/output values are subject to change for such reasons as measurement errors and
arbitrariness. DEA efficiency scores need to be examined by considering such factors, and resampling calculates the confidence
interval by four new innovative models.

Network & Floating Licenses
We offer a network license of DEA SolverPro. With a network license installed on your server,
you can use DEA SolverPro from your client PC's on your local area network. This function is quite useful
in a class room environment where a number of students may use the software concurrently.
A floating license, by which you can install the program on multiple PCs, is also available now.
Use the software on any one of them at a time by activating it with a dongle.
You can use the software at work, or at home, by carrying a licensed USB dongle. It is a convenient way to use
the program on mutiple PC's without purchasing multiple licenses. See details in Purchase Information below.
Excel Versions and 32/64 bit mode
Currently following Excel Versions are supported: Excel 2007 (32 bit mode only), 2010, 2013 and 2016 (32 bit & 64 bit mode, Version 10 and later).
For desktop DEA SolverPro Versions 9, 8, and 7, we have separate modules for 32 bit and 64 bit mode Excel. I.e., if you want to use the software on 64 bit
mode Excel, you need to use the 64 bit version of our software. You get both (32 bit & 64 bit) Versions in the installation package or in downloads,
so use the right one. For Versions 10 and later, there is one module which works for both 32 bit and 64 bit mode Excel.
For floating and network licenses, we now have the 64 bit Version available, starting Version 12c. Note before Version 12c, we only supported the 32bit mode.
Usage on Excel 2013 and 2016
Problems in accessing data files have been reported on Excel 2013. We fixed the problems, and Version 10 and later ones work
with Excel 2013 or 2016. If you have 8 or an older version and if you want to use it on Excel 2013 or 2016, we suggest that you get an upgarde as described below.
Protected View on Excel 2010 & 2013 & 2016
All the samples files are in protected view mode initially. As such, users are encourgaed to remove such protection at the beginning.
It is highly recommended that you remove protection from any Excel files, outside in Excel and DEA updates..
