摘　　要：测试性设计是提高系统可靠性、安全性、维修性、保障性的重要前沿技术,决定了系统故障检测率和隔离率,直接影响系统的维护(测试)成本。系统测试性设计包含结构化设计、模型化设计、数据驱动设计等多种设计策略。其中,数据驱动设计于近年逐渐兴起并成为重要发展方向之一,该类方法通过对系统测试与故障之间的关系进行建模,依据测试结果进行故障推理,形成故障诊断方案。首先,简要回顾了系统测试性设计的发展历程;其次,重点介绍了测试性设计的研究进展,分析总结了结构化、模型化、数据驱动3类测试方案;然后,介绍了测试性诊断策略构建,根据测试方案中的建模方法确定诊断策略的构建技术,并总结归纳了每类技术的研究特点和适用性;最后,探讨了当前复杂系统测试性设计面临的挑战性问题和可能的未来研究方向。Testability design is an important cutting-edge technology to improve system reliability,safety,maintainability and supportability,which determines the failure detection and isolation rates and directly affects system maintenance(testing)cost.The testability design of the system has gone through a variety of design strategies,such as structural design,modeling design,and data driven design.Among them,data-driven based design is a rising strategic emerging strategy.They model the relationship between system tests and faults,and infer faults from test results to form diagnostic strategies.This paper firstly reviews the development process of system testability design and then focuses on the latest progress of testability scheme design including structure-based,model-based and data-driven-based schemes.After that,research status of each approach are sorted out and summarized.Then,the construction of the test diagnostic strategy is introduced,and the construction technology of the diagnostic strategy is determined according to the modeling method of the testability scheme,and the research on each type of technology is summarized.Finally,the current challenging problems and possible future research directions are discussed.
