Designing Component-Based Systems (CBS) that exhibit a good trade-o between multiple quality criteria is hard. Even after functional design, many remaining degrees of freedom of different types (e.g., component deployment, component selection, server configuration) in the CBS span a large, dis-continuous design space. Automated approaches have been proposed to optimise CBS models, but they only consider a limited set of degrees of freedom, e.g., they only optimise the selection of components without considering the deployment, or vice versa. They propose a flexible and extensible formulation of the design space for optimising any CBS model for a number of quality properties and an arbitrary number of degrees of freedom.
