Analyzing discrete-time bulk-service queue

Similarity:

This paper analyzes a discrete-time multi-server queue in which service capacity of each server is a minimum of one and a maximum of customers. The interarrival- and service-times are assumed to be independent and geometrically distributed. The queue is analyzed under the assumptions of early arrival system and late arrival system with delayed access. Besides, obtaining state probabilities at arbitrary and outside observer's observation epochs, some performance measures and waiting-time...

Performance analysis of single server non-markovian retrial queue with working vacation and constant retrial policy

Similarity:

This paper analyses an M/G/1 retrial queue with working vacation and constant retrial policy. As soon as the system becomes empty, the server begins a working vacation. The server works with different service rates rather than completely stopping service during a vacation. We construct the mathematical model and derive the steady-state queue distribution of number of customer in the retrial group. The effects of various performance measures are derived.

Finite buffer GI/Geo/ 1 batch servicing queue with multiple working vacations

P. Vijaya Laxmi, Kanithi Jyothsna (2014)

RAIRO - Operations Research - Recherche Opérationnelle

Similarity:

This paper analyzes a discrete-time finite buffer renewal input queue with multiple working vacations where services are performed in batches of maximum size “”. The service times both during a regular service period and vacation period and vacation times are geometrically distributed. Employing the supplementary variable and imbedded Markov chain techniques, we derive the steady-state queue length distributions at pre-arrival, arbitrary and outside observer’s observation epochs.
