Queuing theory is used to model many systems in different fields in our life; it is used in simple systems and complex ones. The main idea in the application of a mathematical model is to measure the performance measures of the application in order to improve the performance of the system. This paper will present an analytical method and simulation modelin estimation the appropriate model for a...

by simulation is the performance of a probabilistic model of a multiprogrammed single-processor computing system operating under demand paging. Results of experiments on statistical methods .for improving the efJiciency of the simulation are presented. Estimates of the response variables in the simulation are reported for a variety of conditions of system overhead, queuing delays, and transient...

In this paper, we present a new type of Globus resource allocation manager (GRAM) called RMF (Resource Manager beyond the Firewall) for wide-area cluster computing. RMFmanages computing resources such as cluster systems and enables utilization of them beyond the rewall in global computing environments. RMF consists of two basic modules, a remote job queuing system (Q system) and a resource allo...

The phenomena are balking can be said to have been observed when a customer who has arrived into queuing system decides not join it. Reverse is particular type of wherein the probability that will balk goes down as size up and vice versa. Such behavior in investment firms (insurance company, Mutual Fund Company, banks etc.). As number customers firm up, it creates trust among potential investor...

Modeling line in non standard way occurs when layout constraints and inappropriate placing customer is limited for taking customer service by the servant. The aim of this study is providing a mixed model for analyzing the system of non-standard line with Considering the limitations of the layout with Using the concepts and principles of queuing theory So that the main parameters of the model fo...
