Here the reliability systems engineering means around faults/failures and setting the efficiency as the goal to understand the mechanisms and rules of the faults/failures, and study on the technologies and methods of fault/failure diagnosis, prognosis, prevention, maintenance and support based on the theories of system science and engineering, and use these theories and methods to carry out a series of related technology and management activities in engineering. RSE covers a broad range of research and application areas on reliability, maintainability, testability, supportability, safety, and also quality, etc. Considering current situations in reliability systems engineering areas in China, the ICRSE (International Conference on Reliability Systems Engineering) will be held every two years, and the 2015 ICRSE is the first time conference. The 2015 ICRSE conference will cover many topics: technologies and methods on reliability, maintainability, testability, supportability, safety (RMTSS), such as modeling, simulation and optimization; design, analysis, test and evaluation; standards and methodologies; information technology; product warranty and quality engineering; risk assessment and control; human factors engineering; software reliability, etc.
