Reliability Analysis


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).


Ongoing Topics

  • 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
  • Maintainability
