Software product lines can significantly improve productivity, shorten the development cycle, improve product quality and user satisfaction. Real-time display control platform general using the method to realize software reuse of software product line, from the communications, navigation, radar display control projects in areas such as series software can be derived from the common needs and variable demand, design a display control framework and common software reusable component and reuse into the library, finally applied to the similar project in the form a series of software products. The successful implementation case of a radar display control project fully proves that the real-time universal display control platform based on a software product line has the characteristics of high reuse, high quality, and low cost.
