 DEA-Solver Pro  資料包絡分析軟體

近年來已經有很多使用資料包絡分析(Data Envelopment Analysis, DEA)來評估許多不同種類實體效益的多種應用，在很多不同背景的國家中從事不同的活動。一個原因是，因為經常有未知的複雜因素，很多動作牽扯到多次輸入和輸出之間的關係，DEA已經提供對解決這些情況的可能性。例子包括：在不同的地理位置美國空軍基地的維護活動，或在英國和威爾斯警察的火力分配，賽普勒斯和加拿大銀行各分部的收益，美國、英國和法國的大學展現他們的教育和研究過程中的效率，這些種類的應用可以評價城市、地區和國家的效益，藉著各式各樣的輸入和輸出：包括"社會上"和"安全網"的支出當作輸入資料，和各種"生活品質"的尺寸當做輸出的資料。
 
 
 
Recent years have seen a great variety of applications of DEA (Data Envelopment Analysis) for use in evaluating the performance of many different kinds of entities engaged in many different activities in many different contexts in many different countries. One reason is that DEA has opened up possibilities for use in cases which have been resistant to other approaches because of the complex (often unknown) nature of the relations between the multiple inputs and multiple outputs involved in many of these activities (which are often reported in non-commeasurable units). Examples include the maintenance activities of U.S. Air Force bases in different geographic locations, or police forces in England and Wales as well as performances of branch banks in Cyprus and Canada and the efficiency of universities in performing their education and research functions in the U.S., England and France. These kinds of applications extend to evaluating the performances of cities, regions and countries with many different kinds of inputs and outputs that include "social" and "safety-net" expenditures as inputs and various "quality-of-life" dimensions as outputs.

Latest Releases

The latest release of version 15 is 15a, with a new feature Negative Data SBM, which handles negative data often encounted in industrial applications, like financial data. Now we can handle positive and negative data in a single DEA model. The efficiency scores are units invariant. For more details, go to newsletter 18.

Excel Versions and 32/64 bit mode

Currently following Excel Versions are supported: Excel 2007 (32 bit mode only), 2010, 2013 and 2016 (32 bit & 64 bit mode, Version 10 and later).

For desktop DEA SolverPro™ Versions 9, 8, and 7, we have separate modules for 32 bit and 64 bit mode Excel. I.e., if you want to use the software on 64 bit mode Excel, you need to use the 64 bit version of our software. You get both (32 bit & 64 bit) Versions in the installation package or in downloads, so use the right one. For Versions 10 and later, there is one module which works for both 32 bit and 64 bit mode Excel. If you have one of these old versions, upgrading to the latest DEA-SOLVER-PRO version is highly recommended.

For floating and network licenses, we now have the 64 bit Version available, starting Version 12c. Note before Version 12c, we only supported the 32bit mode.
