متن کاملM m m Queue with Balking, Reneging and Additional Servers
In this paper, we consider a multi-server queuing system in which additional servers are allowed for a longer queue to reduce the customer’s balking and reneging behavior. The customers are assumed to arrive in Poisson fashion and their service- times follow exponential distribution. The number of servers in long run depends on the queue-length. We obtain equilibrium queue size distribution. Th...
متن کاملM M m K Queue With Additional Servers and Discouragement (RESEARCH NOTE)
Waiting in long queue is undesirable due to which in some practical situations customers become impatient and leave the system. In such cases providing additional servers can reduce long queue. This investigation deals with multi-server queueing system with additional servers and discouragement. The customers arrive in poisson fashion and are served exponentially by a pool of permanent and addi...
متن کامل$(m,n)$-algebraically compactness and $(m,n)$-pure injectivity
In this paper, we introduce the notion of $(m,n)$-algebraically compact modules as an analogue of algebraically compact modules and then we show that $(m,n)$-algebraically compactness and $(m,n)$-pure injectivity for modules coincide. Moreover, further characterizations of a $(m,n)$-pure injective module over a commutative ring are given.
متن کاملM/M/1 Feedback Queue Subject to Catastrophe and Repairment
In this paper, an M/M/1 queue with instantaneous Bernoulli feedback is studied in the event of server failure, the catastrophe occurs and after repair, it starts to work again. The transient response for the probability function of the system size is presented. The steady state analysis of system size probabilities and some performance measures of system are provided. Then the resu...
