λ: Avg. Arrival Rate

by unknown authors , 2009
"... 1. HW1 due today in class. No late homeworks, because it’s being graded tonight. 2. I need grading volunteers for tonight. Remember that you will also be designing one new interesting homework question. 3. You will get HW1 solutions on Wednesday. 4. HW2 will be on the web site today and is due in on ..."

of jobs in the system is equal to the product of the average arrival rate into the system and the average time a job spends in the system. This also holds when the “system” consists of just the “queues ” in the system. Little’s law applies to both open and closed systems, and we’ll explain it in both

In recent years the Federal Aviation Administration (FAA) has made reduction of runway incursions a priority for surface operations throughout the national airspace system. In a series of experiments conducted in April 2001, NASA studied alternatives designed to improve the efficient movement of surface traffic and reduce runway incursions at Los Angeles International Airport (LAX). The experiments were conducted in NASA Ames Research Center’s FutureFlight Central (FFC), a full virtual reality air traffic control tower cab simulator. This paper details the lifecycle of the safety studies from design to execution, describes the alternatives that were proposed for runway incursion reduction, and offers a brief summary of the experiment results.

EVALUATING ARRIVAL RATE UNCERTAINTY IN CALL CENTERS

by L. F. Perrone, F. P. Wiel, J. Liu, B. G. Lawson, D. M. Nicol, R. M. Fujimoto, Thomas R. Robbins, D. J. Medeiros, Paul Dum
"... Inbound call center operations are challenging to manage, in large part because there is considerable uncertainty in estimates of arrival rates, which vary over time. We have developed a general purpose simulation model for inbound call center operations which supports time varying and uncertain arr ..."

Binary Exponential Backoff is Stable for High Arrival Rates

by Hesham Al-ammal, Leslie Ann Goldberg, Phil Mackenzie , 1999
"... Goodman, Greenberg, Madras and March gave a lower bound of n 1 8 n) for the maximum arriaval rate for which the n-user binary exponential backo protocol is stable. Thus, they showed that the protocol is stable as long as the arrival rate is at most n 120 n) . We improve the lower bound, showin ..."

Arrival rate approximation by nonnegative cubic splines

by Farid Alizadeh, Jonathan Eckstein, Nilay Noyan, Gábor Rudolf , 2004
"... Estimating the arrival rate function of a non-homogeneous Poisson process based on observed arrival data is a problem naturally arising in many applications. Cubic spline functions are particularly well-suited to represent such estimates since they are suciently versatile and easy to handle computat ..."

MULTIVARIATE ARRIVAL RATE ESTIMATION USING SEMIDEFINITE PROGRAMMING

by S. Jain, R. R. Creasey, J. Himmelspach, K. P. White, M. Fu, Farid Alizadeh
"... An efficient method for the smooth estimation of the arrival rate of non-homogeneous, multi-dimensional Poisson processes from inexact arrivals is presented. The method provides a piecewise polynomial spline estimator. It is easily parallelized, and it exploits the sparsity of the neighborhood struc ..."

PASSENGER ARRIVAL RATES AT PUBLIC TRANSPORT STATIONS

by Marco Luethi (corresponding, Ulrich Weidmann, Andrew Nash , 2006
"... The amount of time spent waiting at a public transport station is a key element in a passenger’s assessment of service quality and in mode choice decisions. Many transport models estimate the average wait time is half the headway for small headways and use a maximum waiting time for headways over a ..."

This research evaluated the influence of headway and other factors on passenger arrival rates at public transport stations based on data collected at 28 stations in Zurich’s public transport network. It found that even at 5-minute headways, some passengers

Forecasting emergency medical service call arrival rates

by S. Matteson, Mathew W. Mclean, Dawn B. Woodard, Shane, G. Henderson - Annals of Applied Statistics , 2011

Covariate information is captured via simple constraints on the factor loadings. We directly model the count-valued arrivals per hour, rathe ..."

Stability properties of constrained queueing systems and scheduling policies for maximum throughput in multihop radio networks

by Ros Tassiulas, Anthony Ephremides - IEEE Transactions on Automatic Control , 1992
"... Abstruct-The stability of a queueing network with interdependent servers is considered. The dependency of servers is described by the definition of their subsets that can be activated simultaneously. Multihop packet radio networks (PRN’s) provide a motivation for the consideration of this system. We ..."
Abstract - Cited by 949 (19 self) - Add to MetaCart
. We study the problem of scheduling the server activation under the constraints imposed by the dependency among them. The performance criterion of a scheduling policy m is its throughput that is characterized by its stability region C,, that is, the set of vectors of arrival rates for which the system
