软件工程.COSMIC-FFP.函数长度测量方法

[中文适用范围]： 本国际标准规定了 COSMIC-FFP 功能规模测量方法的一组定义、约定和活动。 它适用于以下功能领域的软件： a) 支持业务管理所需的应用软件；例如银行、保险、会计、人事、采购、分销或制造。 b) 实时软件，其任务是跟上或控制现实世界中发生的事件；例如，用于电话交换机和消息交换的软件、嵌入到控制机器（例如家用电器、电梯和汽车发动机）的设备中的软件，用于过程控制和自动数据采集，以及计算机操作系统内的软件。 c) 上述的混合体。 示例：航空公司或酒店的实时预订系统。 本国际标准不是为测量软件或其部分的功能规模而设计的，软件或其部分的功能规模： d) 具有复杂的数学算法或其他专门且复杂的规则的特征，例如可能在专家系统、模拟软件中找到的规则、自学习软件和天气预报系统，或e)处理连续变量，例如音频声音或视频图像，例如可以在计算机游戏软件、乐器等中找到的。 然而，在使用 COSMIC-FFP 功能规模测量方法的组织的本地环境中，可以以作为本地标准有意义的方式来测量这些 FUR。 本国际标准包含为此目的本地定制方法的规定。 [外文原描述]： ISO/IEC 19761:2003 specifies the set of definitions, conventions and activities of the COSMIC-FFP Functional Size Measurement Method. It is applicable to software from the following functional domains: application software which is needed to support business administration;real-time software, the task of which is to keep up with or control events happening in the real world;hybrids of the above. ISO/IEC 19761:2003 has not been designed for measuring the functional size of a piece of software, or its parts, which: are characterized by complex mathematical algorithms or other specialized and complex rules, such as may be found in expert systems, simulation software, self-learning software and weather forecasting systems, orprocess continuous variables such as audio sounds or video images, such as may be found, for instance, in computer game software, musical instruments and the like. However, within the local environment of an organisation using the COSMIC-FFP Functional Size Measurement Method, it may be possible to measure these FUR in a way which is meaningful as a local standard. ISO/IEC 19761:2003 contains provision for the local customisation of the method for this purpose.
