Graduation Project:

• In this project, we used a structured Data Envelopment Analysis (DEA) approach in the selection and ranking of the best Six Sigma project among several different projects, the approach starts with the application of simple DEA and then discusses the shortcomings of this DEA formulation. Hence, points out the need for the Aggressive and Benevolent formulations that tend to constrain the linear programming problem to obtain more reliable results; Aggressive and Benevolent formulations are then compared to the Super Efficiency model and discusses the differences of the results generated by these models.
