基于偏差分析的航空装备软件费用控制方法

针对航空装备软件费用控制与管理问题，提出了一种基于偏差分析的费用控制策略，给出了重大偏差标准设定方法，将挣值管理引入到航空装备软件费用监控中，解决了软件费用与进度的控制问题。研究结果表明，基于挣值管理的方法可准确掌握项目费用和进度的实施情况，当费用或进度偏离计划时，能够及时发现项目研发中存在的问题并采取策略进行调整，有效实现了软件费用和进度的监控与管理。

Aviation equipment software cost control method based on variance analysis

In order to deal with the problem of aviation equipment software cost control and management, a software cost control method based on variance analysis is proposed. From this method, the qualitative and quantitative of great variance criterion are given. The earned value management method is introduced into aviation equipment software cost supervisory control so as to solve the problem of software development cost and schedule control. The software cost and schedule implementation situation can be reflected exactly from the analysis result of the earned valued management method. When the cost or schedule deviates to program plan, the problem can be found from the method in software development, and adopted in the software cost and schedule control and management.
