Win4DEAP provides a convivial Windows front end for DEAP which is a DOS program that performs data envelopment analysis. Tim Coelli is the author of DEAP, which is the program that actually performs data envelopment analysis. That program and similar software is 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 runs on 32-bit Windows platforms. It has been tested on Windows XP but it probably runs on all versions of Windows starting with Windows 98..

The screen shot (Figure 1) shows the data entry page of Win4DEAP. It contains the data from the first example file provided by Prof. Coelli with his DEA programme DEAP. The result from two runs by DEAP.EXE are available but cannot be seen. They would be visible by pressing the 'Run 1' or the 'Run 2' tab. A third run is about to be performed. Note how DMU3 and OUT2 are disabled. They will not be included in this run.

Installing

1. Make sure Tim Coelli's program DEAP.EXE is installed and running on your computer. It can be found Centre for Efficiency and Productivity Analysis at the University of Queensland. It bears repeating, make sure DEAP.EXE works before trying to install Win4DEAP.

2. Remove any old version of Win4DEAP. If the installation program was used with the older version, there is an unistall program to remove it.

3. Click on the downloaded installation program WinDEAP114.EXE to start it.

The destination folder (directory) for Win4DEAP can be any folder desired.

Win4DEAP can be installed in the same directory as DEAP.EXE. It will eliminate the need for the next step. Click on the folder containing DEAP.EXE in the Select Destination Directory dialogue. "Win4DEAP" will then be tacked on to the directory (See Fig. 2, where DEAP.EXE's directory is C:\Program Files\DEA\deap). Remove \Win4DEAP. Answer Yes whenasked if "you would like to install to that directory anyway".

4. If Win4DEAP was installed in a directory other than DEAP's, it will be necessary to specify the location of DEAP.EXE. This has to be done once. It can be done now or it can be done the first time a DEA analysis is run. To do it now, start Win4DEAP.EXE and click on Preferences in the File menu. Enter the full path to DEAP.EXE. It will be clear if the path is correct are not.

Example files

Tim Coelli's four examples are provided in Win4DEAP format (extension .ded). They are in a folder called, appropriately, Examples which is itself located in the folder in which Win4DEAP was installed.

Instructions for use of Win4DEAP

Win4DEAP behaves much like a spreadsheet. It should be relatively easy to use for those familiar with Excel, Quattro etc. As of version 1.1.0 a help file is included with Win4DEAP.

By default, WinHelp format help is not displayed in Windows Vista or Windows 7. WinHelp can be installed, for free, on such systems. Consult http://support.microsoft.com/kb/917607 for details and links to the software. If you do not wish to install WinHelp, a version of the help file in the newer chm (compiled html) format is installed along with Win4DEAP. The chm file can be displayed from the Help menu. Unfortunately, Win4DEAP itself does not know about this file and cannot use it to display help topics.

WARNING:

Win4DEAP should be considered beta software. Backup data often and in both the native DED format and standard CSV or TXT formats.

Removing Win4DEAP

An uninstall program is installed along with Win4DEAP.EXE. See the help file for further details.
