In this paper, we introduce an approach, where architecture specification is converted to a graph representation. Based on this representation, we automatically generate possible evolution paths, evaluate quality attributes for different architectural configurations, and optimize the selection of a particular path accordingly. We illustrate our approach by modeling the software architecture evolution of a crisis management system. \itemrv{~} \itemcc{} \itemut{} \itemli{doi:10.1007/978-3-642-23798-0\_28} \end
