Journal Title: Logistics and Transport - Year 2012, Vol 15, Issue 2
Abstract
This paper presents an example application of a software program developed using the programming language VBA and designed for modelling queuing systems in the field of transport. The program enables users to quantitatively determine the indicators of the queuing systems. In order to show the program’s capabilities and how it can be used, two scenarios have been considered - modelling single-server and multi-server queuing systems of type M/M/1 and M/M/S, respectively, having a Poisson incoming flow of requests and exponentially distributed service times.
