This paper presents a clustering approach for grouping components of similar reusability using an already worked out fuzzy data set [2]. Research has shown that, component based systems development concept benefits the object oriented software development. A Component based system achieves flexibility by clearly separating the stable parts of systems from the specification of their composition. Many software systems contain many similar or even identical components and these components are developed from scratch over and over again which require extra effort. So to minimize the extra effort in developing these components, it is more beneficial to reuse the existing components. To reuse components effectively in Component Based Software Development, it is required to quantify the reusability of components. However it is difficult to use clustering approach to predict reusability. This paper discusses a technique to cluster components of similar reusability together for the purpose of minimizing the efforts of the developer using agglomerative hierarchical clustering. Components attribute affecting the reusability are classified into rules using fuzzy system and are then taken as the inputs to the proposed clustering model.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
