Therefore, many assessment theories and computational approaches have been proposed, and they can be divided into two categories: time domain and frequency domain. Besides static failure, fatigue life (or fatigue failure) is an important design criterion for the safety of mechanical and building structures. This research develops a new topological optimization (TO) method to assess dynamic fatigue failure in the frequency domain for random excitation forces. Finally the research trends are prospected. A kind of research thought of using Axiomatic Design theory to solve reliability design problems is proposed. The research progresses related to the reliability Axiomatic Design method are intensively analyzed. The complexity theory and relationship between complexity and reliability design are reviewed.
The concepts of Axiomatic Design theory such as the independence axiom and information axiom are introduced. This paper analyzes the common reliability design methods and the existed problems. As a conceptual decision design method of product design, Axiomatic Design is combined with reliability design, which provides a new way to solve the problem of high reliability design of products.

With the increasing complexity of the product, the conventional reliability design methods can hardly support the realization of high reliability requirements, and how to carry out high reliability design has become the bottleneck problem which is urgent to be solved in the product development.
