Titre : Stochastic comparison for resource sharing models. Auteur : Florence Forbes, Olivier Francois, Bernard Ycart Date : Mars 96 --KEY-WORDS-- Resource sharing - philosophers process - interacting particle systems - stochastic comparison --ABSTRACT-- New models for resource sharing situations are defined. these models are Markovian versions of the drinking philosophers problem introduced by Chandy and Misra. They can be viewed as interacting particle systems, for which the classical stochastic comparison results for spin systems are generalized. Several applications to resource sharing models are proposed. -- Number of pages : 25 Published in Markov Processes and related Fields, Vol2, 4, 1996.
