Reliability of a system conveys information about the absence of failures, and is usually define as the probability that the system will perform its intended function for a specified time period when operating under normal environmental conditions. Reliability theory, which is the foundation of reliability engineering, deals with the interdisciplinary use of probability, statistics and stochastic modeling, combined with engineering insight into the design and the scientific understanding of the failure mechanisms, to study the various aspects of reliability. With the development of the complex systems, such as advanced aircraft, space station and nuclear power and so on, reliability theories and applications are more and more attention in this century. This workshop serves as a forum for the latest achievements of the advanced theory of reliability modeling and optimization, as well as more focuses on the application of reliability theories. We are looking forward it can attract more researchers to join us.
