| Abstract: | The stress and strength are regarded as fuzzy variables when it is very difficult to get the distribution parameters. By using expert experiences, the reliability model of machine parts stress and strength is established with fuzzy closeness degree method. Formulas for calculating fuzzy reliability are derived. This method can be applied to dispersive data of non normal distribution. |
