Sensitivity of output performance measures to input distributions in queueing network modeling

Cell Dwell Time and Channel Holding Time Relationship in Mobile Cellular Networks

“…Then, it could be necessary to capture more than three moments, even though the lower order moments dominate in importance. Similar conclusion was drawn in (Gross & Juttijudata, 1997). …”

Computation of Steady-State Probabilities for Resource-Sharing Call-Center Queueing Systems

“…Results using simulation to examine sensitivity of results to interarrival-time and service-time distributions [28] favored the performance of the internal-rule system over the external-rule system relative to the expected queue waiting time for all interarrival and service distributions investigated (gamma, lognormal, beta, and Pearson type V; with a variety of shapes). Numerically, networks with Erlang or phase-type service time distributions could be formulated as quasibirth-and-death processes with resultant matrix-geometric solutions.…”

Advanced input modeling for simulation experimentation

“…The inclination to simplify the input model (via use of classical distributions, statistical independence, and time homogeneity) is equally pervasive. Warnings against such simplification are easily found: Bratley, Fox, and Schrage (1987), Kelton et al (1990), Johnson (1987), and Wilson (1997); warnings are implicit in sensitivity analyses such as Gross and Juttijudata (1997), Gross and Masi (1998), and Reilly (1998).…”
