基于 UML 与 IFPUG 功能点度量的装备软件计价方法研究

摘要

随着装备费用需求的不断增加，装备软件单独计价显得非常必要。如何客观、准确地计算软件成本，已成为亟待解决的问题。论文结合装备软件自身的特点，提出了基于 UML 建模的 IFPUG 功能点度量方法，阐述了利用 UML 中最常用的用例图、类图和顺序图三种工件进行功能点度量的方法和步骤，并在某装备软件项目计价活动实施应用，初步验证了其有效性。%With the increasing demand for equipment cost ,equipment software cost alone is valued necessarily .How to objectively and accurately estimate software cost has become a serious problem .Combined with its own characteristics of e‐quipment software ,the paper presents the approach of IFPUG function point estimation based on UML modeling ,and ex‐pounds methods and procedures of function point estimation using three common artifacts such as use case diagram ,class dia‐gram and sequence diagram .The validity of the approach ,which is implemented in the estimation activity of equipment soft‐ware project ,has been validated preliminarily .
