Integrated reliability assessment using varied environment test data

  • The influence of environment on reliability was studied, and a method of integrated reliability assessment using varied environment test data was put forward. The relations of reliability and environment factors were described by the Cox proportional hazards model, and the influences of environment factors were measured. According to the reliability model and the measurement, a new data conversion was proposed to convert the test data of varied environment into that of the same environment. Then the reliability of product was assessed synthetically with the converted test data. With the method, the varied environment test data is used synthetically to enlarge the sample size and increase the information for reliability assessment. Thus, the precision of reliability assessment is improved. The example shows that the method is reasonable, and it is convenient for engineering.
