Queuing Theory

The use of quantitative measures to balance supply and demand for services in order to minimize wait times. Queuing theory is most beneficial in retail establishments; for example, one may use it to determine how many cashiers to have at the grocery store. It is also called waiting line theory.

In [23, 24], the queuing theory is used to describe the charging process and it is proved feasible.
These methodologies include the use of linear programming techniques, fuzzy methods, stochastic programming models, probabilistic models, simulation, and decision theory and queuing theory [5].
With an experiential learning exercise such as that described in this study, students can develop at least an intuitive understanding of how and why queues form-thereby closing the gap that may exist between the lecture/text treatment of queuing theory and the more advanced results that are often illustrated only in spreadsheet models.
The notion of customer impatience appears in queuing theory in the work of [Haight, 1957].
We presented [EQNM.sup.2]L which is a domain specific modelling language based on queuing theory. Extended queuing networks are simply queuing networks with an extension for new concepts that help modelling more accurately.
This fragile market creates a situation where "shocks," or extreme movements in price, occur more frequently than one would expect in a normally distributed supply/demand market under Queuing Theory. Energy problems can be caused by disruptions from all types of energy supplies, such as coal and natural gas.
If this sounds a lot like service time and queue time, it is because the behavior is very similar--so similar in fact that we can use this Oracle "service time" and "queue time" just as OR queuing theory indicates.
To overcome these issues we looked to the queuing theory, which is a methodology that allows one to match random demand with fixed capacity.(2) Queuing principle has been widely used in banking, airline, Internet and telecommunication industries.(2)
Abstract: The goal of this paper is to show that the implementation of the queuing theory could set an optimal capacity of the port container terminal, or a combination of the number of berths and cranes per berth with the minimum costs for the given traffic.
Chris DeFlitch, Hershey Medical Center recently completed a departmental simulation that utilized operation data and queuing theory to evaluate the effect of the addition of a physician to the triage process.
According to the CAL3QHC user's guide, CALINE3 was designed to predict emissions from vehicles under free-flow conditions but does not account for emissions from idling vehicles .The queuing theory added to CALINE3 to produce CAL3QHC reportedly allows for the consideration of idling vehicle emissions by estimating queue lengths.
