if anyone known, pls suggest me how to solve DEA method for optimization and give me the procedure
Dear Palani,
You can use GAMS software to solve many DEA models. There are so many useful videos in following link:

Dear Palani,
As suggested by Masoud, GAMS is certainly the most appropriate software to implement DEA as you will have to write explicitly the linear programming and understand the mathematical structure of it.
Nonetheless, two main drawbacks of GAMS are its non-friendly user interface and its price. These reasons explains why plug-and-play software are now available online (free or not), and allow implementation of the method at a low programming-time cost.
R software and many packages developed lately (benchmarking, fear...) are also a good opportunity to implement DEA without entering into the programming part, but you should consider your result carefully as you don't have a fully clear vision on the underlying mathematical program.
To be synthetic, you can implement DEA in few hours on plug-and play software or function, or in many monthes or years on linear programming software, depending on how in-depth you want to understand the method, its mathematical and economical assumptions, and their consequences on the structure of the model.
R and softwares online can maybe be a good eye-opener on DEA potential, but if you pursue in using the method, i would recommend as Palani to invest time (and money) in GAMS, which will give you a very generic platform to implement any kind of model, and their statistical robustness test.
Hope these comments from a non-expert user help.
Cheers,
D
I work with DEA-Solver-LV(V8) that so helpful and user-friendly excel solver which cover all major DEA models

Dear Palani,
First, determine to input and output variables,
Second, choose a DEA software, there are many free softwares on the web,
At the end, carry out the analyze to get the results. You can also check this paper
Article Performance Evaluation and Ranking of Turkish Banking Sector
I published DEA from Amazon kindle version.
See my anouncement of DEA on RG.
I open my DEA code in the book.
Unlimited users are free.
The Price is $9.99.
