Abstract

Component-based Software Engineering uses components to construct systems, being a means to increase productivity by promoting software reuse. This work deals with the Component Selection Problem in a multilevel system structure. A fuzzy-based approach is used to construct the required system starting from the set of requirements, using both functional and non-functional requirements. For each selection step, the fuzzy clustering approach groups similar components in order to select the best candidate component that provide the needed required interfaces. To evaluate our approach, we discuss a case study for building a Reservation System. We compare the fuzzy-based approach with an evolutionary-based approach using a metric that assess the overall architecture of the obtained systems, from the coupling and cohesion perspective.
