Generating instantiations of contextual scenarios of periodic events

We consider an expressive formalism to deal with temporal constraints between periodic events which takes into account different components such as frame times, numeric quantification, periods, and qualitative temporal constraints. We define the notions of (contextual) concretization of temporal constraints in such a formalism and of the (contextual) scenario of a knowledge base of temporal constraints. We then use these notions to introduce an algorithm which generates an instantiation of events which satisfy a scenario
