Environmental factor, as an important parameter in reliability assessment, has been an important issue in the reliability engineering research. The definition of environmental factor for success-failure type data is the unreliability ratio of products between two different environments. When the experimental data obtained were zero-failure data, the value of denominator would be zero when using the...
Besides the Wiener and Gamma processes, the inverse Gaussian (IG) process is recently proposed as an attractive yet flexible family for degradation modeling. Since degradation test depends heavily on the degradation model chosen for a product's degradation process, we discuss the optimal design for degradation tests specifically based on the IG process. Other than an optimal design with pre-estimated...
A zero failure always exists in modern electronic products and its reliability based on zero-failure data has become a problem that needs to be solved to improve the reliability of the whole equipment. This paper solved the problem of parameter selection in the E-Bayesian and hierarchical Bayesian estimation methods and then applied these two Bayesian methods to the zero-failure data of an electric...
