In order to reduce the traffic congestion and to enhance the capacity of urban road intersections, this paper builds a model of the vehicle queuing system for the intersection by queuing theory Based on Monte Carlo algorithm, this paper carries out simulation and analysis of the vehicle queuing system in the intersection by MATLAB, analyses, the status of vehicle queue to reduce the vehicle que...

The aim of this work is to develop regenerative approaches based on discrete time events simulation and framework of general semi-markov processes (GSMP). It’s expanding field of classic methods for research of queuing networks, which are simulated ineffective (or impossible at all) with classical regeneration. We suggest that multidimensional markov process describe system. It consist of discr...

Queuing models are important tools for studying the performance of complex systems, but despite the substantial queuing theory literature, it is often necessary to use approximations in the case the system is nonmarkovian. Phase type distribution is by now indispensable tool in creation of queuing system models. The purpose of this paper is to suggest a method and software for evaluating queuin...

In CT examination, the emergency patients (EPs) have highest priorities in the queuing system and thus the general patients (GPs) have to wait for a long time. This leads to a low degree of satisfaction of the whole patients. The aim of this study is to improve the patients' satisfaction by designing new queuing strategies for CT examination. We divide the EPs into urgent type and emergency typ...

The “Horizontal Y” shaped queuing model in which there is bulk infinite arrival of patients, but available M services are limited. discrete flow patients the system reduced continuous and a diffusion equation used. In terms means variances inter-arrival time distribution, this process number servers used, imposing reflecting boundaries. inspiration for analysis came from Aradhye Kallurkar [2], ...
