Version 1.1.3

copyright 2002-2012 Michel Deslierres


Win4DEAP provides a convivial Windows front end for DEAP which is a DOS program that performs data envelopment analysis. It 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 98, ME and XP. Cursory verification showed that it also runs on Windows 2000, Windows Vista and Windows 7 (64 bit).

DEAP, a program that performs data envelopment analysis (DEA), is written by

Tim Coelli
Adjunct Professor

University of Queensland, Australia


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. Each 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.

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

Obtaining Win4DEAP

The latest version of Win4DEAP will be available on the Web : Two packages are available.

WinDEAP113.ZIP All the files to do your own installation. It will be easier to use the following programme.

WinDEAP113.EXE An installation program which takes care of most of the details. It's use is described below. The installation performs the following changes :
1. All the files found in WinDEAP113.ZIP are placed in a user specified folder.
2. An uninstallation programme is added to that folder.
3. An uninstall entry is added to the Control Panel's Programs and Features.
4. A folder, named Win4DEAP, is added to the start menu with links to Win4DEAP, the uninstall, this file, etc.
5. *.ded files are associated with Win4DEAP


1. Make sure Tim Coelli's programme DEAP.EXE is installed and running on your computer. It can be found on the Web: It bears repeating, make sure DEAP.EXE works before trying to install Win4DEAP.

2. Click on the installation programme WinDEAPv110.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 when asked if "you would like to install to that directory anyway".

3. 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.

Removing Win4DEAP

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

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 (WinHelp format) is included with Win4DEAP.

Win4DEAP on Windows Vista or Windows 7

By default, WinHelp format help is not displayed in Windows Vista or Windows 7. WinHelp can be installed, for free, on such systems. Consult for details and links to the software. If you do not wish to install WinHelp, a version of the help file in the newer format is installed along with Win4DEAP. A link to this file is available from the start menu. Unfortunately, Win4DEAP itself does not know about this file and cannot use it to display help topics.

While Win4DEAP is running it may change the behaviour of windows when dragged or resized. The content of a window will not be udated during this type of operation. Once Win4DEAP is stopped, the normal behaviour should be restored. If it is not, click on the programme FixDragMode installed alongside Win4DEAP.


Jean-Marc Huguenin will discuss, among other things, use of DEAP.EXE and Win4DEAP in a chapter of an upcoming book and is preparing a guide to DEA where again DEAP.EXE and Win4DEAP will be mentionned. Here is the reference to the chapter
