I work with DEA-Solver-LV(V8) that so helpful and user-friendly excel solver (add-in) which cover all major DEA models

You can download it free by the link:

I have found DEA Solver Pro to be quite extensive and reliable however it is not open source and costs $800 for educational institutions.

I have successfully used the following free DEA computer program in my master thesis some years ago:

Dears,

I have another question in this regard:

Do you know a free DEA software which can analyze a DEA Input-Oriented CCR model while it has direct restrictions in all weights (ex. LB

Dear Maryam, you can find a free dea software at this web site

FEAR in R not working even with earlier version of R(3.1) as quoted in FEAR document.  I am using only excel, started to explore with r DEA, DEAFrontier and DEAP,

I upload DEAwithCrossEfficient.pdf that is one of first chapter of DEA with CCR and Inverted DEA models and crossEficient published from Amazon.

I explain how to build LINGO SEts model and DEA.

DEAP is good one . You could many models of DEA I have used it

DEAP is good. I found its score similar to LIMDEP.

Benchmarking in R works well . Is LIMDEP an open source?

In DEA-Solver-LV(V8) , the CCR input oriented and CCR output oriented models are giving same results, which is not correct. Can someone please help?

Please use r package benchmarking

Thank You Venkatesh Kanyakumari Sir. I will check.

Is R package benchmarking freely available?

yes any package for R is open source R itself open source. Benchmarking , the default model is VRS and out put oriented.

LIMDEP is not open source and quite Expensive.

Dear Sanchit Saran Agarwal , i dont know if it is late to answer but the CCR models need to be the same answers.

" In DEA-Solver-LV(V8) , the CCR input oriented and CCR output oriented models are giving same results, which is not correct. Can someone please help? "

It is correct! because the model is proportional.

Use Frontier 4 software which you can download from Australian National University
