Problem 2. Evaluating Relative Efficiencies of Decision Making Units Data Envelopment Analysis (DEA) is an application of linear programming used to measure the relative efficiency of operating units with the same goals and objectives. As explained in the course, DEA can measure the relative efficiency of a group of hospitals. The data seen below involving seven teaching hospitals include three input measures and four output measures.
