New decision support system for performance analysis

Data Envelopment Analysis, one of the method of performance analysis, is the non-parametic method in which relative efficiency is measured by using obsevance values of variables belonging to decision making units. Data Envelopment Analysis is a preferable method since it not only shows which decision making unit is effective but also gives advices about turning inefficient decision making units into efficient decision making units. Different types of computer packet programmes may be used for Data Envelopment Analysis. However, there are some deficiencies in these packet programmes prepared in foreign languages. In this study, complately Turkish performance analysis package program has been developed with Microsoft Visual C# programming language covering each of the various features such as the input-oriented and output-oriented CCR (Charnes Cooper Rhodes) - BCC (Banker Charnes Cooper) models, Window analysis, uncontrolled variable status in order to complete the deficiencies. This packet programme is thought to bring added value to our country as it is more useful than its equivalents and it is a domestic article.
