To deal with the internal fuzziness in quality fu nc tion deployment(QFD) system of drier, the models of fuzzy programming in correla tion function and auto-correlation function are established by using fuzzy regr ession and fuzzy programming theory with symmetric fuzzy coefficients. Then the relationship between h value and the extended fuzzy coefficients is analyzed , and the method to find its best value is proposed. Simulation results show tha t the models can help to identify correlation function and auto-correlation fun ction under the condition of uncertain and incomplete information in the product fuzzy design process. These results are usable in various modeling of house of quality.
