Abstract

In this paper, we show that the “most regular” wordin the language formed by all the words containing a fixed numberof each letter of an alphabet gives the optimal resource allocationpolicy of the generic system composed by two processes sharinga resource. This system will be modeled as a Petri net to derivethe proof of this result which is partially generalized to nonperiodic allocation sequences and non rational frequencies. ForN processes sharing a resource, we show that a stronglyoptimal sequence may not exist. In this case, we give an heuristicto find a good allocation sequence which relates to regular wordsin higher dimensions.
