Modeling and Application of IFPUG in Laser Ranging Software

功能点分析法是国际上软件开发组织广泛采用的一种软件规模度量方法。它因发展较早、技术成熟而备受关注,已成为我国军用软件度量的标准方法。本文主要介绍了IFPUG功能点分析法在某激光测距软件中的建模和应用。首先根据软件需求,确定了该软件的应用边界,并识别了度量的数据功能和事务功能。同时,根据数据功能单元和复杂性来计算功能点数,并以此推算出激光测距软件的规模。研究表明,IFPUG功能点分析法测量的软件规模在理想范围之内。本文初步验证了功能点分析法在激光测距软件中的有效性,为进一步量化软件项目的开发、提高软件质量提供参考和依据。

Function point analysis is a software size measurement, which is widely used by international software organizations. It has gained wide acceptance due to its early development and mature technology, and it is also recommended for Chinese military software size measurement. The paper mainly introduces the application of IFPUG function point analysis in a laser ranging software. Firstly, the application boundary is determined based on the software requirements specification, and the data functions and transaction functions are also identified. Accordingly, the number of function points is obtained according to the data function unit and complexity, and the software size is calculated based on this. The research indicates that the software size measured by IFPUG is ideal. This paper preliminarily verifies the effectiveness of the function point analysis in a laser ranging software, and provides a reference for quantifying software projects and improving software quality.
