To measure the performance of the branches, two crisp inputs and three fuzzy outputs are considered. We normalize these crisp inputs and fuzzy outputs because their units are not same. The performances of all crisp inputs and fuzzy outputs are then aggregated to form an overall crisp input and fuzzy output performances. The weights associated with the crisp inputs and fuzzy outputs are same. Applying the first Yager ranking function to the fuzzy overall output yields a real number. Its efficient can be calculated. This paper also consider the six output weights: (1, 0, 0), (0, 1, 0), (0, 0, 1), (0.5, 0.25, 0.25), (0.25, 0.5, 0.25), (0.25, 0.25, 0.5) and consider the second Yager ranking function. We perform a computerized experiment that indicates no significantly differences exist among the weights associated with the outputs, ranking function and efficient. Therefore, weights associated with the outputs and ranking functions can not significantly affect the order of the efficient.
