Abstract:

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.
