This paper deals the transient analysis of a queueing system with working vacation in which server may encounter breakdowns. Customers enter batches according to Poisson process and receive service FCFS mode. Whenever finds nobody, starts during renders at slower rate than normal one. Further, we considered two types customer’s impatience balking reneging. We solved differential equations find ...

We study a single station two-stage reneging queue with Poisson arrivals, exponential services, and two levels of behaviors, extending the popular Erlang A model that assumes constant rate. derive approximate analytical formulas representing performance measures for our following Markov chain decomposition approach. Our not only give accurate results spanning heavy-traffic to light-traffic regi...

In the present investigation transient, G x/G/m queuing model with balking and reneging has been studied. The diffusion process with elementary return boundary has been used for modeling purpose. The probability density function (p. d. f.) for the number of customers in the system has been obtained. In special case, the steady state results that tally with those of Kimura and Ohsone have been e...

Customer impatience has a very negative impact on the queuing system under investigation. If we talk from business point of view, the firms lose their potential customers due to customer impatience, which affects their business as a whole. If the firms employ certain customer retention strategies, then there are chances that a certain fraction of impatient customers can be retained in the queui...

We augment existing studies of spot procurement contracts by introducing relational contracting. We first show that at intermediate interest rates, the form of procurement contract affects the parties’ reneging temptation on a given relational contract, and hence affects the best relational contract that is sustainable. We also show that relational contracts make contracts less complete and com...

Queues are a ubiquitous phenomenon. This research investigates consumers’ affective experiences in a queue and their decisions to leave the queue after having spent some time in it (reneging). In particular, we find in our first two studies that, as the number of people behind increases, the consumer is in a relatively more positive affective state and the likelihood of reneging is lower. While...

Economic performance depends crucially on how parties adapt to changing circumstances. We therefore study how the organization of economic activity can facilitate such adaptation. Where spot transactions would produce inefficient adaptation, we ask how governance structures (allocations of control) can facilitate relational contracts that improve on spot adaptation. We show that the optimal gov...
