Software Components Assembly with an Appreciated Qos

The objective of CBSE (Component-Based Software Engineering) is the development of big software by integrating of existing components. The traditional concept of applications development by writing code was replaced by the assembly of prefabricated components. The goal of the assembly is to reach a coherent application from a set of software components. We present in this article a method enabling the evaluation of the quality of software components assembly. This method allows us choosing the best components’ composition in order to obtain the system required by the user in term of quality (non-functional needs).
