Abstract
Conference Title: 2016 Annual Reliability and Maintainability Symposium (RAMS) Conference Start Date: 2016, Jan. 25 Conference End Date: 2016, Jan. 28 Conference Location: Tucson, AZ, USA Existing reliability models of complex systems have mostly assumed instantaneous failure propagation with a global effect leading to conservative analysis results on system reliability. This paper proposes a new reliability model considering competing failure isolation and failure propagation with random propagation time. The assessment method utilizes the total probability theorem and binary decision diagrams, providing a practical procedure for the reliability analysis of complex systems subject to competing failures and random propagation time. Results can be used in arranging maintenance activities and optimizing resource allocation. The proposed model is validated using a case study.
