Abstract To solve the problems such as the insufficiency of the required data and the low credibility in
reliability prediction for diesel engine in engineering, this paper utilizes the property of fuzzy number which is
suitable for quantifying fuzzy information bines the fuzzy sets and the traditional similar product method
by using fuzzy sets theory and interval analysis. Then it puts forward a new reliability prediction method which
combines the fuzzy similar product method and the prehensive evaluation, which is then used to do the
fuzzy prediction on the reliability of
