航天器总体设计正确性和接口实现正确性的及时验证,是提高航天器这类复杂系统可靠性的重要手段。本文提出一种基于模型检测的虚拟测试方法。方法采用窗口树模型（WTM）对复杂系统进行建模,采用状态转移图（STG）作为系统规约刻画系统行为的正确性。方法通过提出基于自动机的模型检测机制,实现了一种面向航天器系统级测试的虚拟测试平台（VTP）原型系统。该平台支持虚拟测试准备、虚拟测试执行和虚拟测试评估等功能,模拟并实现复杂系统总体设计正确性的验证和接口实现正确性的验证。

英文摘要：

As a complex system,the verification of design and interface implementation of spacecraft is an effective way to increase its reliability.In this paper a virtual test method,which is a fusion approach on the combination of automata-based model checking theory and systems engineering theory,is proposed.An automaton of window tree model（WTM）based on multi-tree to describe the system behavior as a system-model is used on one hand,and a state transition graph（STG）based on automaton to describe design correctness as a specification is used on the other hand.An automaton-based model checking mechanism is proposed to build the foundation of the virtual test method.Moreover,the two main aspects of the method,including the design correctness verification and the interface implementation verification,are defined.Finally,a case study is followed to illustrate the technical approaches of virtual test method,the modelling process of a complex system as well as the verification process in a virtual test platform（VTP）,which implements the method.The VTP is composed of three main features of the virtual test configuration,the virtual test execution as well as the virtual test evaluation.
