Engineering systems are increasingly complex. They need to meet advanced requirements for mission-critical fields with a low failure tolerance. As unexpected failures during the designed lifespan of a system may lead to catastrophic consequences, their reliability modeling and assessment are of utmost importance. The reliability modeling should achieve the assessment at a reasonable confidence level to help decision-makers arrive at sound decisions in practice.

However, the modeling and assessment of real engineering systems often face an environment with a mixed uncertainty, due to either the inherent randomness (aleatory uncertainty) or a lack of knowledge (epistemic uncertainty). Particularly, available information for reliability modeling is often imperfect, arising from insufficient accumulated knowledge, biased prior information, limited field test data, etc. This makes reliability assessment considering imperfect information and mixed uncertainty an imperative yet challenging task.

This Special Issue will be a collection on the latest innovative ideas, cutting-edge research results, and applications for complex engineering system reliability modeling and assessment. Applications in practical industrial settings will also be included.
