摘　　要：阐述故障可诊断性评价与设计研究的必要性并给出相关定义。从基于定量模型和定性模型两个方面对故障可诊断性评价研究现状进行介绍,包括梳理各种方法的基本思路,给出各方法的优缺点与适用范围,总结与故障可诊断性相关的定量指标等;从基于优化问题、故障传播关系、变量约束关系以及故障影响变量等方面对测点优化配置方法进行介绍,并给出各种方法的优缺点;最后展望故障可诊断性未来的发展方向。The necessity of the fault diagnosability evaluation and design as well as the related definition is addressed. A brief summary of the general developments in fault diagnosability evaluation covering the quantitative-based and the qualitative-based methods are proposed, including the main idea, characteristic and the field of application. Meanwhile, some quantitative criteria are given. Then, the fault diagnosability design are introduced from some aspects, such as based on the optimization problem, the fault propagation relationship, variable constraint relationship and the fault-related data. Finally, the perspective of the fault diagnosability evaluation and design are predicated.
