Two types of service; Re-service; Modified vacation; Balking; Service interruption Abstract This paper deals with the steady state analysis of batch arrival retrial queueing system with two types of service under modified vacation policy, where each type consists of an optional re-service. An arriving batch may balk the system at some particular times. After the completion of each types of serv...

Abstract: This paper treats a discrete-time batch arrival queue with geometrically working vacations and vacation interruption. The main purpose of this paper is to present a performance analysis of this system. For this purpose, we first derive the probability generating function (PGF) of the stationary system length at the departure epochs based on the embedded Markov chain technique. Next, w...

A deaf, partially sighted, severely retarded autistic girl, 11 years, 6 months of age, received approximately 2 years of occupational therapy, where sensory integration procedures were employed to reduce self-stimulation. Videotaped time samples of the amount of stereotypies showed a consistent reduction from the time of starting therapy to an interruption for vacation and surgery for scoliosis...

In this paper we address the problem of designing an interruptible system in a setting in which n problem instances, all equally important, must be solved. The system involves scheduling executions of contract algorithms (which offer a tradeoff between allowable computation time and quality of the solution) in m identical parallel processors. When an interruption occurs, the system must report ...

In this paper, we considered a batch arrival feedback retrial queue with two phase of service under Bernoulli vacation schedule and orbit search. At the arrival epoch of a batch, if the server is busy, under repair or on vacation then the whole batch joins the orbit. Where as if the server is free, then one of the arriving customers starts his service immediately and the rest join the orbit. At...

The retrial phenomenon occurs inherently in a wide range of queueing systems. majority models do not account for vacation. However, practice, systems undergo vacations maintenance or other reasons. In this study, we provide an in-depth analysis the many possible when Bernoulli are effect. Moreover, study outlines key principles and reviews relevant literature. framework queue with vacation has ...
