摘要:随着商品级软件在数字化仪控系统中逐步得到应用,为确保核安全,需对商品级软件执行适用性评价和验收(CGD),其中,关键特性的识别是执行CGD活动一个重要的步骤。本文提出从系统的角度识别商品级软件的功能性能特性;依据IEC 60880和IEC 62138,参考软件质量模型,从软件设计特性、软件设计过程体系和使用经验3个维度识别可信性特性。该方法已在实践中得到应用,可供同行借鉴。

Abstract: With the application of commercial software in digital instrument control system, in order to ensure nuclear plant safety, it is necessary to evaluate and accept the commercial software (CGD)in which the identification of critical characteristics is an important step in the implementation of CGD activities. This paper proposes to identify the functional performance characteristics of commercial software from the perspective of system. According to IEC60880 and IEC 62138, referring to software quality model, dependability characteristics are identified from three dimensions of software design, software design process and experience. The method has been applied in practice and can be used for reference.

Key words: Commercial software; CGD; Critical characteristics
