Machine Repair Queueing System with with Non-Reliable Service Stations And Heterogeneous Service Discipline (RESEARCH NOTE)
نویسندگان
چکیده مقاله:
This investigation deals with M/M/R/N machine repair problem with R non-reliable service stations which are subjected to unpredictable breakdown. 1here is provision of an additional server to reduce backlog in the case of heavy load of failed machines. 1he permanent service stations repair the failed machines at an identical rate m and switch to faster repair rate when all service stations are busy. By using matrix geometric theory, the formulae for obtaining the optimal number of service stations is derived.

On a dual queueing system with preemptive priority service discipline
In this paper, we use matrix–analytic methods to construct a novel queueing model called the dual queue. The dual queue has the additional feature of a priority scheme to assist in congestion control. Detailed structure of the infinitesimal generator matrix is derived and used in the solution process. Using a computational algorithm, which utilises a combination of iterative and elementary matr...
متن کاملtwo server queueing system with single and batch service
a two server queueing system with single and batch service is considered in this paper. the arrival process is assumed to be poisson and the service rate follows an exponential distribution. server-i serves the customers in both single and batch service, while server-ii serves the customers in batch service only. the laplace transform of the transient and steady state behavior of the model is c...

The purpose of this paper is to analyze the effect of a particular control doctrine applied to the service mechanism of a queuing process with lapse. It is assumed that the service discipline is FCFS (first come, first served), arrival process is Poisson, service time distribution is exponential, service process is one phase and the capacity is infinite. It is also assumed that the customer may...

متن کاملUniversity of Debrecen Performance Analysis of Finite-source Retrial Queueing Systems with Heterogeneous Non-reliable Servers and Different Service Policies
This paper deals with the performance analysis of multiple server retrial queueing systems with a finite number of homogeneous sources of calls, where the heterogeneous servers are subject to random breakdowns and repairs. The requests are serviced according to random and fastest free server disciplines. The novelty of this investigation is the different service rates and different service poli...
متن کاملDesigning a service science discipline with discipline
R. J. Glushko This paper relates our experiences at the University of California, Berkeley (UC Berkeley), designing a service science discipline. We wanted to design a discipline of service science in a principled and theoretically motivated way. We began our work by asking, ‘‘What questions would a service science have to answer?’’ and from that we developed a new framework for understanding s...
