Analysing dynamic function scheduling decisions

Function allocation, as a process used in the construction of dependable complex systems, is a significant aspect of the design and implementation of interactive systems. It involves a documented and rational process for deciding what aspects of the system should be controlled by which human roles in the system and how the system should be automated to support these roles effectively. As computer systems have become more advanced, and the control of systems more complex, the notion of dynamic function allocation becomes increasingly desirable where in certain situations the automation may take over or give back function to the human user. In this paper we explore a further variant of dynamic function allocation that reflects typical work activity where the dynamic scheduling of activities takes place on the time dimension. The paper discusses this approach to dynamic function allocation called dynamic function scheduling and discusses the role that timed model checking may play in helping identify dependable dynamic function scheduling solutions.
