The conditional distribution of waiting time given queue length in a computer system
Department of Mathematics, University of South Florida, Tampa, Florida, USA
In this paper, a model for the conditional distribution of waiting time given queue length is developed for a queue type computer system. The distribution is specified by its percentiles. Consideration of data from a real computer system leads to the model
[equation: see PDF]
where tp is the p-the percentile of waiting time; b is queue length and ap, b0 and cp are parameters. The parameters are estimated and their interpretation is discussed.
A second model is developed by considering the distribution of waiting time given queue length to be given by a location and scale change of a standard distribution. The estimation of the parameters leads to the fitting of a table by a mixed additive and multiplicative model.
