Win4Deap 2 provides a convivial Windows front end for DEAP written by Tim Coelli. As the name implies, it is an improved version of Win4DEAP. Contrary to what is sometimes written, Win4Deap 2 and Win4DEAP are not replacements of DEAP. It is the latter, a DOS console program, which performs the numerical calculations required in data envelopment analysis. Win4DEAP 2 will not make DEA calculations without an installed copy of DEAP.EXE. DEAP.EXE will work perfectly well without Win4DEAP 2.
Tim Coelli's DEAP and other similar applications are available at the Centre for Efficiency and Productivity Analysis at the University of Queensland.
The application provides a grid not unlike a spreadsheet to enter data and writes the necessary instruction and data files for DEAP. This means that it is possible to have data files in a folder other than DEAP's. Win4DEAP 2 is a 32-bit Windows application. It has been tested on Windows 7 and 8.1 (64 bit) but it probably runs on all versions of Windows starting with Windows XP.
Win4Deap 2 is free software that is provided as is. The author of the program accepts no responsibility for any damages that could be caused by this software and makes no warranty, whether implied or implicit, about its fitness for any purpose. The user assumes all risks associated with the program. Please read the copyright notice and license agreement for more.
The installation program for the latest version of Win4Deap 2 is available here: Win4Deap2Install-2-1-0-1.exe. Click on the link to start downloading the setup file. Check sums for the installation program are :
Win4Deap 2 can be run as a "standard" Windows' application or as a "portable" application. Roughly speaking,
Most often, a portable program is installed on removable media such as thumb drives. But it is entirely possible to choose to perform a portable installation in a hard drive's folder. Just make sure that you have full read and write rights on that folder. In that case, it will be possible to install DEAP in the same folder. Conversely, if DEAP is already installed, it should be possible to install Win4Deap 2 in the same folder.
The type of installation is specified at the very end of the installation process.
I accept the agreement" if you do and then click on
Program Filesand, on 64 bit systems,
Program files (x86).
Installbutton and, once installation is completed
If a standard installation was chosen, the extension
.wdjson will be associated with Win4Deap 2 which will cause it to be launched whenever a file with that extension is double clicked. Also an uninstall program will be installed. Finally, a menu item will be added to the Start menu. If a portable installation was selected, the file association will not be performed and the uninstall program will not be created.
It is possible to choose DEAP's folder as the destination folder.In that case Win4Deap 2 will find DEAP.EXE. If Win4Deap 2 is installed in a folder other than DEAP's, it is necessary to specify the location of DEAP.EXE in the Win4Deap 2's Preferences dialogue.
Tim Coelli's four examples are provided in Win4DEAP 2 format (extension
.wdjson). They are in a folder called, appropriately,
Examples . In a standard installation, that folder will be in a folder called
Win4Deap2 in the user's
Document folder. In a portable installation, Examples will be in the folder containing Win4Deap2.exe.
Win4Deap 2's help file is not complete. Nevertheless it should not be too difficult to figure out how it works.
Win4Deap 2 should be considered beta software. Backup data often and in both the native wdjson format and standard CSV formats.
An uninstall program is installed along with Win4Deap2.exe if a standard installation was performed. If a portable installation was chosen, manually delete the installed files. No changes were made to the system in that case.
Thanks to Tim Coelli for DEAP without which Win4Deap 2 is of no use.

Thanks to Jordan Russell for the Inno Setup Compiler which was used to create the installation program. The setup compilber can be found on the Web at http://www.innosetup.com.
This application was written in Object Pascal with the open source Free Pascal compiler and the free RAD IDE Lazarus: http://www.freepascal.org/ and http://www.lazarus-ide.org/. Thanks to the team of dedicated volunteers for those excellent open source projects.

Version 184.108.40.206 - Changed version number to 2 to concord with the application's name and fixed many minor bugs.
Version 220.127.116.11 - Fixed errors with filenames containing non ascii characters and other minor bug corrections.
Version 18.104.22.168 - various bug corrections, compatibility with MDeap 2 project files completed.
Version 22.214.171.124 - bug correction (i) new project was creating value and price vectors twice the needed size and the saved project file was then not readable (ii) the period when working with panel data was not saved in models. Also modified the (json) file read/write routines to obtain interoperability with upcoming MDeap 2 program.
