基于GJB5000A的软件估算技术在EICAS系统中的应用

Application of Software Estimation Technology Based on GJB5000A in EICAS System

针对军用软件的开发规模和复杂程度越来越大,传统的定性分析技术无法保证军用软件质量和稳定性的问题。提出以GJB5000A要求为指导,用软件估算技术方法定量分析并估算软件项目。首先探究军用软件成熟度模型基础理论知识,阐述GJB5000A的优越性,接着分析GJB5000A中软件估算有关技术,而后,介绍试点项目EICAS系统功能软件用途,最后,结合EICAS系统试点项目叙述如何利用软件估算技术方法,进行软件规模估算、平均生产率估算和工作量估算。通过项目实践验证该技术行之有效,为项目实践中推进实施GJB5000A过程管理提供一个参考方法,开启一种新的备选范例和思路。

In view of the growing scale and complexity of military software development,the traditional qualitative analysis technology cannot guaran⁃tee the quality and stability of military software.This paper puts forward a quantitative analysis and estimation of software projects with the guidance of GJB5000A requirements.First of all,it studies the basic theory of GJB5000A and explains the superiority of GJB5000A.Sec⁃ondly,it analyzes the related technology of software estimation in GJB5000A.Then it introduces the function and software of EICAS sys⁃tem.Finally,it describes how to use the software estimation technique method to carry out the software size estimation,average productivity estimation and workload estimation with the project of EICAS system.Through the project practice,it is proved that the technology is effec⁃tive.It provides a reference method in the implementation of the practical application of GJB5000A,and opens up a practical alternative and example.
