摘要：Improving the quality of software systems design is the most important issue during the evolution
of object oriented software systems. In this paper we are focusing on the problem of determining
refactorings that can be used in order to improve the design of object oriented software systems. Refactoring
([6]) is a major issue to improve internal software quality. This paper aims at presenting a new
hierarchical agglomerative clustering algorithm, HARS (Hierarchical agglomerative clustering algorithm
for restructuring software systems), that identifies the refactorings needed in order to restructure a software
system. Clustering([10]) is used in order to recondition the class structure of the system. The
proposed approach can be useful for assisting software engineers in their daily works of refactoring software
systems. We evaluate our approach using the open source case study JHotDraw ([7]), emphasizing
its advantages in comparison with existing approaches.
