The Meaning and Role of Value in Scheduling Flexible Real-Time SystemsReport
The real - time community is devoting considerable attention to flexible scheduling and adaptive systems. One popular means of increasing the flexibility, and hence effectiveness, of real-time systems is to use Value - based scheduling. It is surprising however, how little attention has been devoted, in the scheduling field, to the actual assignment of value. This paper deals with value assignment and presents a framework for undertaking va1ue - based scheduling and advises on the different methods that are available. A distinction is made between ordinal and cardinal value functions. Appropriate techniques from utility theory are reviewed. An approach based on constant value modes is introduced and evaluated via a case example. ‘The work reported in this paper was undertaken as part of the AFERT Project (041) supported by a joint EU US funding arrangement
