Abstract

Developing an appropriate mathematical model for assessing reliability of high reliability products is still an open issue. In order to get accurate estimation of reliability indexes, the reliability information which issued from different sources should be utilized in the process of reliability assessment when the reliability test data is scarce. An original method for evaluating reliability of high reliability products is provided in the presence of aleatory and epistemic uncertainties. The proposed approach applies the transferable belief model interpretation of the Dempster–Shafer theory to represent the contribution of each reliability active to product reliability and to evaluate the product reliability. A reliability assessment model is put forward.
