Assumptions on the VT task model in DESIRE

This paper presents assumptions underlying the modelling and specification of the VT task in DESIRE. These assumptions are about the modelling of tasks in general, the specification of task models in DESIRE, the modelling of the VT task in particular, and the problem solving method developed for the VT task. By an explicit formulation of such assumptions, different problem solving methods for one task can be compared and the reuse of problem solving methods is facilitated.
