Main results

  • an unified approach to stability of Jackson-type and multiclass regenerative networks based on a characterization of renewal process is developed [1987], 1990, 1991, 1997, 1998, 1999];
  • stability conditions for a multiserver queue with nonidentical servers are established [1985, 1993, 1997];
  • positive Harris recurrence of a closed network with multiserver stations and nonidentical servers is proved, [1994];
  • regenerative network decomposition is developed [1994];
  • the tightness of some secondary network processes with application to stability analysis is established, [1995, 1997];
  • a general construction of weak regeneration in an open Jackson-type queueing network is given [1995, 1998];
  • an efficiency of steady-state weakly regenerative simulation of some networks is established [19961,19962, 1998, 2001, 2002, 20031, 20032];
  • instability conditions of Jackson-type and multiclass open networks are found, [1998, 2002];
  • two-sided bounds for output perturbations via external input perturbations are deduced for the Jackson-type network with multiserver stations, [1999, 2002];
  • interrelation between long-range dependence and regenerative simulation are found [2002, 2003];
  • general two-stage approach to stability analysis of regenerative queueing processes is developed, [2004];
  • an applicability of regenerative simulation to estimation of a steady-state performance measure of a long-range dependent process is justified, [20041, 20042, 2005];
