Optimal components selection based on fuzzy-intra coupling density for component-based software systems under build-or-buy scheme

Abstract Component-Based Software Engineering (CBSE) is an approach to building and developing software systems based on components. In component-based systems, there are various components, including Commercial off the Shelf (COTS) in-house developers can build their desired component as or COTS. The problem of deciding optimally between COTS components one major challenges developers, which known selection problem. This be resolved by evaluating criteria for optimality in then solving optimization techniques. this paper, attempt was made optimize through multi-objective maximizing Fuzzy-Intra Coupling Density (Fuzzy-ICD) functionality objective functions, also taking into account budget, delivery time, reliability, Fuzzy-ICD constraints problems. Fuzzy ICD a more accurate criterion calculate relationship Cohesion obtained fuzzy computing each them, Meyers classification. Thus, after two-criterion model formulation, solved multi objectives approach. Finally, proposed method evaluated performing case study financial-accounting system. Comparison results showed that could select optimal with maximum fewer rates time Budget (0.29, 0.43, 1.1 s, 88$ were improved functionality, Fuzzy-ICD, respectively).
