Resumen de Fluid model criterion for instability of re-entrant line with infinite supply of work

Yongjiang Guo

• Using a fluid model approach, we obtain a sufficient condition for re-entrant lines with infinite supply of work to be unstable, which generalizes the results for re-entrant line of Dai (Ann. Appl. Probab. 6: 751�757, 1996). We apply the result to two special re-entrant lines with infinite supply of work as follows. In addition, we get necessary conditions for the corresponding fluid model to be weakly stable.
