In management and social systems which contain human factors, there exist many cases that data including the human vagueness are treated. In this paper, as the foundation of the analysis of the correlation between several kinds of fuzzy data the method estimating the bivariate moments of a population from fuzzy observation data is considered. It is usually desired that we get accurate observations as much as possible. However, in the treatment of the fuzzy data, it is reasonable to think that we observe the fuzzy events as the fuzzy interval data classified by fuzzy boundaries. Thus, in this paper, we define the fuzzy data using the concept of the probability of fuzzy events proposed by Zadeh and propose the method estimating the bivariate moments by the fuzzy data using the usual statistical calculation. Furthermore, the availability of the method is confirmed by the numerical example, the simulation and the simple observation experiments.

A simplified fuzzy reasoning method and a iterative learning algorithm based on the steepest gradient method are proposed. The inverse dynamics model is identified by the iterative learning algorithm. By the simplification of the reasoning, a mathematical models of fuzzy reasoning can be represented by a multi-linear function. The efficiency of the iterative learning algorithm is proved in cases of parity check digits and higher order functions. The convergence of the algorithm is discussed. And, an advanced algorithm using stepwise refining of the fuzzy partition is proposed. As an example of learning control, a computer simulation of robotic manipulator is presented and compared with the ones by neural network models.

Sometimes the gear shift control of automatic transmissions provides for poor drivability. For example, for driving a car with a manual transmission on a mountainous road which has many bends, it is better not to shift into high gear. On the other hand, an automatic transmission will shift one its own in this situation. Since the automatic transmission will shift into high gear when the driver depress the accelerator pedal in front of the bend. So improvement of this mismatch between driver's desire and the characteristics of the automatic transmission is needed. With a view to settling this problem, fuzzy reasoning that inferred the driving circumstance by virtue of fuzzy reasoning knowledge was applied. The membership functions were identified by the results of a largequantity of experimental data using least mean square method. The fuzzy logic system enables us to properly adjust the gear shift of the automatic transmission to complicated driving circumstances.
