在国外网站上发现的一个开源DEA软件，windows和unix系统肯定可以用，苹果系统未测试，欢迎一起学习交流。
windows系统安装方法（更多系统安装方法见下面英文）：
第一步将压缩文件解压；
第二步从lpsolve-v5.5.2.0文件夹中，根据你的系统和所安装的java版本（去java官网下载安装即可），将里面的两个.dll文件复制到C盘，Windows文件夹下，应该根据java的版本选择是复制32位的还是64位的，比如我的电脑是64位windows系统，但我复制的32位的才安装成功。
第三步从SWT文件夹中复制相应系统下的swt.jar文件复制到软件的OSDEA-GUI-v0.2_lib文件夹下。
安装成功，可以开心的运行OSDEA-GUI-v0.2.jar文件做测试了。

1. Unzipping the OSDEA-GUI zip file

• Create a folder wherever you want on your system (e.g. 'OSDEA-GUI').
• Put the OSDEA-GUI-vX.X.zip file in this folder.
• Unarchive the zip file .
• You should now have a lpsolve folder, a *_lib folder, a SWT folder and an executable jar (the OSDEA-GUI program).
  

2. Installing lpsolve

The lpsolve DLLs are included in the OSDEA downloads. If you have downloaded the OSDEA GUI program, the lpsolve files are in the folder: lpsolve-v5.5.2.0\yourSystem. If you are using the source code, they can be found under: DEASolver\lpsolve\yourSystem folders.

To install lpsolve, you simply need to copy the lpsolve library and the java stub to a system directory:

• On windows, select the 32 or 64 bits lpsolve DLLs (resp. lpsolve55.dll and lpsolve55j.dll) depending on the version of the JRE you are using. Copy them to:
  • C:\Windows\System32 for Windows machines with the exception of
  • C:\Windows\SysWOW64 if you use the 32 bits lpsolve DLL on a 64 Bits Windows system (i.e. if you are running a 32 bit JRE on a 64 bits OS).
    
• On Linux (*nix) systems:
  • Select the 32 or 64 bits lpsolve libraries (resp. liblpsolve55j.so and liblpsolve55.so) and copy them to the /usr/lib directory (alt./usr/local/lib - otherwise run ldconfig to add the lpsolve libraries to your system's libraries path).
    
• On mac (osx32):
  • use the build-osx build file with the liblpsolve55.dylib library.
    
  
  

3. Copying the swt.jar file to the lib folder

The last thing required is to copy the swt.jar library for your systems to the 'OSDEA-GUI-vX.X_lib' folder. The steps are as follows:

• Confirm which JVM you have installed: open a terminal and type java -version.
• Locate the corresponding swt.jar library: browse to the 'SWT' folder and go to the folder corresponding to your OS/JVM. For example, if you are using windows and have a 32 bits JVM, you need to use the swt.jar library located in the win32 folder.
• Copy the swt.jar library and paste it in the 'OSDEA-GUI-vX.X_lib' folder.
  

If you're already installed the lpsolve libraries on your system, you can run the program by double-clicking on OSDEA-GUI-vX.X.jar.

Running OSDEA

Congratulations, you've installed OSDEA-GUI. You can now run the program by double-clicking on the OSDEA-GUI-vX.X.jar file (the file might simply be called 'OSDEA-GUI-vX.X' on your system).
