Please try the Free version first and make sure the Free version works on your PC and your version of Excel.

No refunds after the software is delivered (emailed). Thank you.

(A few cases have been reported that non-English version of Excel encounters a runtime error and has to stop the program when  the Risk Solver Platform is installed. The causes of that is due to the Solver product. Users who plan to use the DEAFrontier under other Solver products are strongly advised to test the free DEAFrontier version under Risk Solver Platform.)

The above license fee includes a 1-month free technical support. The technical support is provided only by email and we do not guarantee any turn-around time for answering technical help. The free 1-month technical support is only for using the DEAFrontier software and does not deal with the DEA modeling issue.


DEAFrontier uses Excel Solver, and does not set any limits on the number of DMUs, inputs or outputs. However, please check www.solver.com for problem sizes that various versions of Solver can handle. The standard Excel Solver shipped with Microsoft Office solves problems with sizes of 200x200 (variables x constraints). Alternatively, the user can use the DEAFrontier with OpenSolver which does not set any limits.

The user will receive DEAFrontier versions that work under Excel 2007-2016 (with the standard Excel Solver and Open Solver), Excel 97-2003, and (Risk) Solver Platform.
