Reliability analysis and improvement for compex engineering systems.
Use different decision making tools (e.g., FMEA, fault tree, AHP, etc.) to analyze system reliability; improve system reliability with minimum cost; redundancy allocation optimization for reliability and cost.

Reliablity, defined as the probability that a system is operatonal after some period of time under the given conditions, is one important factor for evaluating the system capability. For a good system, it is true that the completeness of its features is important; however, if the system has a bad reliability (which means it often fails), the whole advanced features turn out to be nothing. Thus realiability is a crucial aspect for evaluating a system, no matter you want to choose a small product or build a complex engineering system. Safety and quality are all closely related to it. Reliability is becoming one important criterion that finally determines the winning of a product amony all its competitors. It has really wide applications, from information systems, mechanical system, networks, spaceships, airplanes, ships and automobiles (of course EV2 and HEVs are among the applications).
- Failure interactions modeling
- Multi-state reliability modeling and analysis
- Improving both the reliability and robustness of complex engineering systems
- Reliability improvement when failure interactions and multi-stateness are considered
