| Abstract: | This paper combines people's judgments and practice and the probability distribution models from small samples by using the fuzzy mathematic method and the Bayes theory.The result of comparison with finite contrast method by practical computation show that Fuzzy-Bayes method is more realistic and suggesting a new method to determine the probability distribution of parameters. |
