【Abstract】 In this paper, the basic concepts related to software life-cycle models are presented first, the four typical life-cycle models including waterfall model, incremental model, evolutionary model and package-based model, which have been successfully used in aerospace software development in China and abroad, are discussed. Finally, the guidelines on selecting an appropriate life-cycle model for a specific aerospace software project are proposed.更多还原
