Subject of this post-graduate thesis is the development of a web-based application dedicated to enhance the idea of measuring production efficiency in a nonparametric framework, using Data Envelopment Analysis (DEA) models to evaluate the production units. In addition to traditional econometric methods, Data Envelopment Analysis is one of the most widespread methods for assessing the performance of a comparable and homogeneous set of units (Smyrlis 2003). DEA can be roughly defined as a nonparametric method based on linear programming, it is used to empirically measure productive efficiency of decision making units (or DMUs). Since DMUs can come from social and political areas, apart from economics, DEA provides a wide range of applications for the estimate of efficiency. The core of the WebDEA includes an algorithm which encapsulate the CCR and BCC models and use a simplex type algorithm to solve linear programs. In the objectives of the present thesis are included the use for educational purposes, as well as the support to analysts concerning decision-making. The contribution in improving the efficiency of the DMUs is obtained through results that are provided by the software and assist the analyst in the distribution and the reallocation of the resources, in the determination of the “best practice”, in setting objectives and planning of decisions - strategies.
