Afthab Begum, M I2017-04-012017-04-012013https://ir.avinuty.ac.in/handle/avu/2500This paper analyses a single server with bulk service queue with general arrival pattern and multiple working vacation period. The model is analyzed by using Embedded Markov Chain technique. The steady state probability distribution at pre airival epoch and arbitrary epoch are derived and measures like mean queue length are calculated. Finally, through some numerical e.\amples, the parametric effect on the performance measures are discussed and presented graphically.
