Abstract: A process method for zero-failure data of the product is developed synthesized new Bayesian estimate method. When the case of zero-failure data, put forward the definition of new Bayesian estimate for failure rate, and given the new Bayesian estimate of failure rate. After some failure information is introduced by doing an extra-test, define are given for synthesized new Bayesian estimate of failure rate and reliability. Finally, calculations and analysis are performed regarding to zerofailure data of engine, which show that the synthesized new Bayesian method is feasible and easy to operate, convenient to use for engineers and technicians in fieldwork.
