Abstract:

In this study, the two possible techniques of computing efficiency scores of the upper decision making units (uDMU) which contain a lot of sub decision making units (sDMU) and whose inputs and outputs can be summable, are compared with the Monte Carlo technique. This problem appeared while the 2002 FIFA World Cup teams'efficiency scores are computed. Each players can be thought as an sDMU and each team can be thought as an uDMU. Team's efficiency score can be computed by the help of the player efficiency scores or the team data. The results obtained by two techniques are tested by Mann-Whitney U test. The situataion that uDMU's contain sDMU's having the same size repeated for trials with different uDMU and different numbers of inputs and outputs. Trials applied for CCR and BCC, two of the DEA models obtained the paralel results to each others.
