For service-oriented systems the estimation of QoS is an important factor to determine whether a prospective service composition will meet the expectations of its final users. Many approaches to QoS estimation of service compositions have been proposed.

In the past decade, researchers have devised many methods to support and codify architecture design. However, what hampers such methods' adoption is that these methods employ abstract concepts such as views, tactics, and patterns, whereas practicing software architects choose technical design primitives from the services offered in commercial frameworks. A holistic and more realistic approach to architecture...
Several works on using Component-based Development to construct Software Product Lines have been reported. However, shortcomings in both approaches have limited the benefits of combining them in practice for the development of software asset variants. This paper explores the feasibility of using composition operators to construct such variants from pre-existing software components. The variants are...
