DEAFrontier TM
Microsoft® Excel Add-In
 DEAFrontier
TM is a Microsoft® Excel
Add-In for solving Data Envelopment Analysis (DEA) models developed by Joe Zhu
DEAFrontier uses Excel Solver as the engine for solving the DEA models. In order to run the DEAFrontier software, Excel Solver must be installed in the Excel. The Excel Solver Parameters dialog box has to be displaced once before the DEAFrontier software is loaded. Otherwise, the DEAFrontier software may not run. DEAFrontier software's capacity is set by the Excel Solver. For example, the standard Excel Solver shipped with Microsoft Office solves problems with sizes of 200x200. As a result, the DEAFrontier will solve problems with up to 199 DMUs. If one needs to deal with more than 199 DMUs, then one needs to upgrade the standard Excel Solver. Please check www.solver.com for problem sizes that various versions of Excel Solver can handle. (A few cases have been reported that Excel encounters a runtime error and has to stop the program when the Risk Solver Platform is installed. The causes of that is due 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.) Software update March 1, 2010: New models (slacks-based super-efficiency models and two-stage netwok models) are developed. The user is now able to select the sheet storing the data. Please visit the Support link for models included in the software.
