Reliability Analysis Based on Coupled Relationship

In the usual reliability analysis, researchers often acquire the reliability information about a product by reliability tests and usually regard the product as a whole object to study. Also, the relationships between the attributes of the product are usually ignored. Base on the non-IIDness learning, the attributes of objects are more or less interacted and coupled. Thus, this paper analyzes the coupled relationships between each pair of product attributes and the coupled relationships between each product attribute and reliability lifetime of the product. Specifically, the attributes we analyzed are continuous. The level of interplay between each pair of attributes and between each attribute and product lifetime can be observed by coupled correlation matrices.
