Abstract
A management and economic system have complex systems. For this reason, it is hard to handle a management and economic area's data. Hitherto, there are many researches to investigate the structure under obtained data and analyze such data. H. Tanaka et al. proposed a Fuzzy regression model to illustrate the potential possibilities inherent in the target system. J. C. Bezdek proposed a Switching Regression Model based on a Fuzzy Clustering Model to formulate a forecasting model. The model proposed by Bezdek is to separate mixed samples coming from plural latent systems and apply each regression model to the group of samples coming from each system. So there are many achievements. However, it is hard to illustrate a rough and a moderate possibility of the target system.
In this paper, in order to deal with the possibility of a social system, I will propose a possibility forecasting model.
