Based on researching the traditional software reengineering model, consult the cores of UML and RUP, design the iterative and increasing software reengineering model based on the UML and RUP, and define the phases and important actions.

• 本文在研究软件再工程传统模型的基础上,吸收UML和RUP的思想,构建出基于UML和RUP的软件再工程的迭代、增量模型,并定义其阶段和关键活动。
