需求追踪管理是核电厂安全级DCS系统开发与软件V&V的重要任务。本文基于DCS系统分布式架构的特点，以系统需求与DCS系统架构为基础，将需求分配到不同的子系统中，建立“需求-子系统”二维平面矩阵，对该平面矩阵沿系统开发生命周期展开追踪，形成“需求-子系统-生命周期阶段”三维需求矩阵。三维需求矩阵能够对整个系统开发生命周期内的需求实现及变更响应进行清晰表达、管理与追踪，有效识别出开发活动对于需求的偏离，提示项目风险，提高软件产品质量，适用于核电仪控系统中基于计算机的分布式控制系统的需求追踪。

Requirement traceability management is the important task for NPP safety DCS application software development and V&V.In this article,based on system requirements and DCS system structure,requirements are distributed to different subsystems,so as to establish“requirements-subsystem”two-dimensional matrix.After tracking its system development life cycle,we creat“requirements-subsystem-life cycle phase”three-dimensional requirement matrix.Three dimensional requirement matrix can express,manage and trace the requirements realization and response during the whole system life cycle,and effectively identify the deviation of development activities for the requirement.As a result,project risk can be prefigured,the quality of software products is enhanced.It is applicable to requirement tracing based on the computer distributed control system in nuclear power plant I&C.
