摘　　要：重构可以改善软件系统的内部结构,提高软件可理解性、可维护性,而又不改变软件的外部行为。传统的源码层次的重构虽有很多重构工具的支持,但是对于复杂软件的重构难度大,容易出错。针对这种情况,提出基于程序蓝图模型层次的重构。考虑到UML模型直观性的特点,给出UML类图模型在系统体系结构上的重构操作和实例,为重构在软件框架结构上的实施提供有力的支持。深入研究过程蓝图模型使用树形结构来描述程序的方法,定义过程蓝图相关重构操作并给出具体操作实例及过程,最后从过程蓝图模型生成新的源码。实验结果表明,UML模型和过程蓝图模型层次上的重构,提高了重构的抽象级别和效率。该方法能有效支持复杂软件的重构,并减少出错率。Refactoring is a technique to improve the comprehensibility and maintainability of software systems by changing their internal structure without altering their external behavioural properties. Although traditional source-level refactoring has been supported by a lot of refactoring tools,the refactoring of complex software is very difficult and is prone to error. In view of this situation,we put forward a program blueprint model hierarchy-based refactoring. Taking into account the intuitive feature of a UML model,we proposed the refactoring operations and implementation examples of UML class diagram model on system architecture. These operations provide a strong support for the refactoring implemented on software framework architecture. We have researched deeply the method of procedure blueprint model using a tree structure to describe the program,and defined in this paper the refactoring operations correlated to procedure blueprint as well as showed some specific examples and procedures of these refactoring operations. Finally,from the procedure blueprint model the new source codes can be generated.Experimental results showed that the refactoring on UML model and procedure blueprint model hierarchy improves the abstraction level and efficiency of refactoring. This method can effectively support the refactoring of complex software and reduce the error rate.
