Analysis of a renewal batch arrival queue with a fault-tolerant server using shift operator method

چکیده
Motivated by the fault tolerance for manufacturing, we investigate a renewal input bulk arrival queue with fault-tolerant server, in which server can keep working low service rate even if partial failure occurs. Only when there are no customers system, be removed. To explore performance measures of queue, more generic and simpler algorithm based on right shift operator method solving difference equations is employed to obtain queue-length distributions at different time epochs. The significant feature this lies that it does not require derivation transition probability matrix corresponding embedded Markov chain. Furthermore, resort distribution pre-arrival epoch quickly get expected sojourn an arbitrary customer. Finally, help Pad $$\acute{\mathrm{e}}$$ approximation, several representative numerical examples illustrated tables graphs, under show how verify correctness our theoretical results through Little’s law.

Analysis of Operating Characteristics for the Heterogeneous Batch Arrival Queue with Server Startup and Breakdowns
In this paper we consider a like-queue production system in which server startup and breakdowns are possible. The server is turned on (i.e. begins startup) when N units are accumulated in the system and off when the system is empty. We model this system by an M/M/1 queue with server breakdowns and startup time under the N policy. The arrival rate varies according to the server’s status: off, st...
متن کاملAnalysis of an Infinite-Server Queue with Batch Markovian Arrival Streams
This paper considers an infinite-server queue with multiple batch Markovian arrival streams. The service time distribution of customers may be different for different arrival streams, and simultaneous batch arrivals from more than one stream are allowed. For this queue, we first derive a system of ordinary differential equations for the time-dependent matrix joint generating function of the num...
متن کاملA Batch Arrival Unreliable Server Bernoulli Vacation Queue with Two Phases of Service and Delayed Repair
This paper deals with batch arrival unreliable queue with two phases of service and vacation under Bernoulli vacation schedule, which consist of a breakdown period and a delay period. For this model, we first derive the joint distribution of state of the server and queue size, which is one of the chief objectives of this paper. Secondly, we derive the pgf of the stationary queue size distribu...
متن کاملA Batch Arrival Queue System with Coxian-2 Server Vacations and Admissibility Restricted
The M/G/1 classic queueing system were extended by many authors in last two decades. The systems with server’s vacation are important models that extend the M/G/1 queueing system. Also another conditions such as admissibility restricted may occure in systems. From this motivation, in this system I consider a single server queue with batch arrival Poisson input. There is a restricted admissibili...
متن کاملA Batch Arrival Retrial Queue with Bernoulli Vacation Policy and Server Breakdown*
This paper examines the operating characteristics of an M/G/1 retrial queueing system under Bernoulli vacation schedule with setup times. The server renders first phase of essential service (FPS) to all the arriving units whereas second phase of multi-optional services (SPS) to only some of them who demand for the same. The server may breakdown according to Poisson process in working state i.e....
