Dallery, Y.; Dubois, D. L’analyse opérationnelle: une approche non stochastique des systèmes de files d’attente (Operational analysis: a nonstochastic approach to queueing systems). (French) Zbl 0584.90029 RAIRO, Autom. Prod. Inf. Ind. 20, 43-86 (1986). Operational Analysis (O.A.) is a recent approach to the study of queuing systems. It enables already known results, proved by means of the stochastic approach, to be recovered under a different set of assumptions. These assumptions pertain to quantities which can be measured from the observation of the system over a finite time horizon. The aim of this paper is to provide an overview of results in O.A. for a single queuing station as well as a single customer class network of queues. Moreover new results are presented for multiple-class networks, in the setting of O.A. A counterpart to the stochastic theorem of F. Baskett, K. M. Chandy, R. R. Muntz and F. G. Palacios [J. Assoc. Comput. Mach. 22, 248-260 (1975; Zbl 0313.68055)] is found. Lastly the strong and weak points of O.A. are discussed, including a comparison with other methodologies.
