基于系统工程过程论验证和确认

为了解析工程过程验证和确认之间的关系,明确两者的作用和方法。对两个概念的形成溯源、异同比较、关系分析、方法应用等角度展开分析和论述。验证和确认是系统工程过程中非常重要的两个技术过程,两个过程中的若干活动的方法比较相似,甚至相同,容易引起混淆。分析结果表明,两者目的不同,方法相似。验证(Verification)和确认(Validation)是系统工程的技术过程中非常重要的两个子过程,是整体过程中的不可缺少的两个环节,区别在于验证过程是确定设计过程和结果是正确的,确认过程则是确定所设计的对象是正确的,是符合利益相关方需求的。

Verification and Validation Based on System Engineering Process Theory

To analyze the relationship between verification and validation of engineering processes and clarify the roles and methods of both, this paper analyzed and discussed the two concepts from traceability, similarities and differences, relationship analysis, method application, etc. Verification and validation are two important technical processes in system engineering. Methods of several activities in two processes are similar, even the same, and confusing. The results show that their purposes were different, while their methods were similar. Verification and validation are two very important sub-processes in technical process of system engineering. They are essential for the integral process. Their difference is that: the verification process is to determine the design process and the results are correct, the confirmation process is to determine the design of the object is correct. They are in line with the needs of stakeholders.
