摘　　要：软件可靠性评估是确定软件能否交付使用的关键步骤.针对软件可靠性评估中测试资源受限的问题,本文阐述一种软件可靠性评估的控制论观点,采用反馈与自适应控制策略指导软件测试过程,介绍一种基于梯度下降方法的软件可靠性评估方法.理论与实验结果表明,基于软件控制论的可靠性评估方法能够在有限的测试资源下获得精度高、稳定性好的可靠性评估结果.Software reliability assessment is a key step that determines whether the software can be delivered for the use or not.Because only limited testing resources are allowed for software reliability assessment,this paper proposes a software cybernetics perspective that introduces feedback and self-adaptive control to guide the software testing process in the software reliability assessment.Also,an adaptive testing strategy based on gradient descent is proposed for software reliability assessment.The theoretical and experimental results show that reliability assessment methods based on software cybernetics can achieve highly precise and stable software-reliability-assessment results using restricted testing resources.
