"' Onno Johan Boxma "'( born 1952 ) is a Dutch mathematician, and Professor at the Eindhoven University of Technology, known for several contributions to queueing theory and applied probability theory.
32.
In this setting, it is used, for example, in queueing theory to model random events, such as the arrival of customers at a store or phone calls at an exchange, distributed in time.
33.
In the queueing theory context, one can consider a point existing ( in an interval ) as an " event ", but this is different to the word event in the probability theory sense.
34.
The paper is well known, and the theorem was described in 1990 as " one of the seminal achievements in queueing theory in the last 20 years " by J . Michael Harrison and Ruth J . Williams.
35.
In the context of queueing theory, the residence time is addressed as " waiting time ", while in the context of supply chain management it is most often addressed as " lead time ".
36.
Most notably, the over-mentioned definition of residence time is extended to stationary random processes by averaging on time ( fluid limit ), obtaining the so-called Little's Law, which is a prominent relation in queueing theory and supply chain management.

Traffic engineers use queueing theory to try and model dense traffic flows, and ( as with other applications of queueing ) there's often a balance to be reached between efficiency and fairness .-- Talk 15 : 06, 17 December 2011 ( UTC)

Tayur has developed models for kanban controlled serial lines, for scheduling of capacitated multi-product systems using methods from queueing theory, stochastic models ( including chance constrained programs ) competitive analysis of on-line algorithms, algebraic geometry and mixed-integer linear programming.
39.
He was the founding Queueing Systems ( journal ) ( 1986 94 ) and has edited several other journals, as well as published the books " Foundations of Queueing Theory " ( Springer Verlag, 1997 ) and " Stochastic storage processes " ( Springer, 1998 ).

In probability theory the "'hypoexponential distribution "'or the "'generalized Erlang distribution "'is a continuous distribution, that has found use in the same fields as the Erlang distribution, such as queueing theory, teletraffic engineering and more generally in stochastic processes.
