Abstract: Retrial queueing systems are characterized by the feature that arriving customers who cannot newlinereceive service immediately may join a virtual queue called orbit to try their request after some newlinerandom time. The main objective of the thesis is to investigate the batch arrival retrial queues with newlinenegative customers and fluctuating modes of service. The content of the thesis is presented in seven newlinechapters. First chapter deals with the preliminary concepts of queueing theory and relevant survey of newlineliterature. Batch arrival retrial G-queue with fluctuating modes of service, admission control and newlinefeedback is analyzed in Chapter 2. In Chapter 3, batch arrival retrial queueing system with negative newlinecustomers, fluctuating modes of service, feedback and randomized vacation is discussed. Chapter 4 newlineis an extension of Chapter 3 by including orbital search. Chapter 5 deals with non-persistent batch newlinearrival retrial G-queue with fluctuating modes of service, random breakdown and repair. Single server newlinebatch arrival retrial G-queue with fluctuating modes of service, random breakdown and delayed repair newlineis presented in Chapter 6. Batch arrival retrial G-queue with fluctuating modes of service, priority, newlinerandom breakdown, delayed repair and orbital search is analyzed in Chapter 7. All the models are newlinemathematically formulated and investigated using supplementary variable technique. The joint newlinedistributions of the server state and the orbit length under steady state are derived. Mean orbit size, newlinemean system size, availability of the server and failure frequency of the server are obtained. newlineStochastic decomposition law is verified and special cases are deduced. Numerical results are newlinecarried out to analyze the effect of parameters on the performance measures.
