Stochastically Enhanced Timed Automata

In our previous work, we have been interested in the development of methodologies and techniques for the specification and verification of distributed multimedia systems, with particular emphasis on object and component-based systems [Blair98a]. This has led us to develop an aspect-oriented style of specification that follows the principles of aspect-oriented programming [AOP00][Murphy99]. Essentially, we decompose a system specification into four aspects: functional, non-functional, management and requirements. Motivations for this choice can be found in [Blair99c]. In the (aspect) programming world, once written, the aspects must be woven together using a set of identified join-points. There is a nice parallel here with aspects in a specification world: once written, our aspects are composed together (using standard parallel composition rules) and the join-points become the set of actions (events) on
