Modelling and refinement in Event-B provides a scalable support for systematic development of complex service-oriented systems. This is achieved by a gradual transformation of an abstract service specification into its detailed architecture. In this paper we aim at integrating quantitative assessment of essential quality of service attributes into the formal modelling process. We propose an approach to creating and verifying a dynamic service architecture in Event-B. Such an architecture can be augmented with stochastic information and transformed into the corresponding continuous-time Markov chain representation. By relying on probabilistic model-checking techniques, we allow for quantitative evaluation of quality of service at early development stages.
