【Abstract】 According to the character of reliability prediction in early design, a similarity based reliability prediction method is presented, in which the qualitative and quantitative similarities based on fuzzy similarity and the similarity in CBR between products are considered. Based on the similarity between a new product and the existed product and available reliability data, reliability prediction can be obtained approximately. The method can be used to predict the reliability of a product in early design.更多还原
