Reliability Engineering and System Safety is an international journal dedicated to the development and application of methods aimed at enhancing the safety and reliability of complex technological systems, such as nuclear power plants, chemical plants, hazardous waste facilities, space systems, offshore and maritime systems, transportation systems, constructed infrastructure, and manufacturing plants. The journal typically publishes articles that analyze substantive problems related to the reliability of complex systems or present techniques and/or theoretical results that have a clear relationship to solving such problems. A key objective is to achieve a balance between academic content and practical applications. The following topics are within the scope of the journal: methods for reliability and probabilistic safety assessment; model and parameter uncertainties; aleatory and epistemic uncertainties; sensitivity analysis; data collection and analysis; engineering judgment and expert opinions; human reliability; test and maintenance policies; models for aging and life extension; systems analysis of the impacts of earthquakes, fires, tornadoes, winds, floods, etc.; codes, standards, and safety criteria; operator decision support systems; software reliability; methods and applications of automatic fault detection and diagnosis; dynamic reliability; design and evaluation of man-machine systems and human interfaces; design innovation for safety and reliability; safety culture; accident investigation and management. The journal does not typically publish articles involving fuzzy sets and related non-probabilistic methods unless they significantly contribute to solving substantive problems related to the analysis of real systems. The journal will contain contributed material in the form of original research papers, review articles, industrial case studies, safety recommendations, and short communications.
