Standard queuing theory describes only the long-term behavior of a queue. The passenger arrivals at the airport immigration fluctuate significantly during the day. The standard queuing theory cannot be used in this case for predicting the queue lengths. Instead time-dependent queuing approaches need to be applied. The queues and arrivals at the incoming immigration of Narita airport were observ...

in this study, the stochastic cell formation problem with developing model within queuing theory with stochastic demand, processing time and reliability has been presented. machine as server and part as customer are assumed where servers should service to customers. since, the cell formation problem is np-hard, therefore, deterministic methods need a long time to solve this model. in this study...

Queuing theory strives to provide analytical solutions to a number of queuing problems. Unfortunately, closed analytical expressions can not be derived for every type of queuing system. Discrete event simulation on the other hand can find solutions to any kind of queuing problem, but the results are stochastic and only specific to a single parameterization. Proxel simulation can bridge the gap ...

Queuing theory is the formal study of waiting in line and is an entire discipline in operations management. This article will give the reader a general background into queuing theory, its associated terminology, and its relationship to patient satisfaction. Queuing theory has been used in the past to assess such things as staff schedules, working environment, productivity, customer waiting time...

In this paper provides the results of research on the development of the method of constructing a model of customs procedures in terms of the theory of queuing systems based on their description by means of functional modeling IDEF0. The technique is based on use of the integrated IDEF0 models and theory of queuing systems with the ability to transition from a description of the system in IDEF0...

Service reliability in a distributed queuing system can be assessed by means of the probability of successfully serving queued tasks in a heterogeneous network of nodes. Moreover, randomness in delays imposed by the communication medium adds to the uncertainties in the shared information among these faulty nodes, which complicates the dynamics of the queuing system. A novel approach based on st...
