Reliability measures the ability of a system performing its intended functions. It is one of the most critical performance measures of today's engineering systems, such as manufacturing systems, aircraft systems, transportation systems and power systems. Most engineering systems are multi-state degraded systems in nature. That is, in addition to the completely working state and totally failed state, they have multiple degraded states or partial failure states in between. However, existing multi-state reliability analysis methods are not flexible and efficient enough to be applied to practical engineering systems with general and complex structures. And more effective approaches are to be developed to improve system reliability and life-cycle cost-effectiveness through system optimization and condition based maintenance.

可靠性衡量的是系统执行其预期功能的能力。它是当今工程系统最关键的性能指标之一，如制造系统、飞机系统、运输系统和电力系统。大多数工程系统本质上是多状态退化系统。也就是说，除了完全工作状态和完全故障状态外，它们之间还存在多个退化状态或部分故障状态。然而，现有的多状态可靠性分析方法不够灵活和高效，不能应用于具有一般和复杂结构的实际工程系统。并将开发更有效的方法，通过系统优化和基于状态的维护来提高系统可靠性和生命周期成本效益。
