Software Metrics for Assessing Reusability of Component Based Software System

For developing Component Based Software System (CBSS), reusability of components plays essential role. Highly reusable components should be selected for developing CBSS to improve its performance and to reduce chances of negligence in society. Reusability is a composite characteristic of any component that depends on several other sub-factors. Researchers have prioritized these sub-factors differently in their research work and assessed various sub-factors. Such three major sub-factors (understandability, customizability, and reliability) are selected in this work for assessing reusability od CBSS. Reusability can be assessed qualitatively or quantitatively. Soft computing techniques can be used for qualitative assessment and software metrics is a good option for quantitative assessment. In this work, software metrics are used to assess the values of these sub-factors quantitatively which are further used to assess the reusability. For showing working of proposed work, experiment is performed on a real world CBSS which was having five different interconnected components, and its reusability is assessed for different weight values.
