A Case Study on Application of CSAN Models on Network Modeling
نویسندگان
چکیده
Petri nets and their extensions are appropriate formalisms for modeling and analysis of communication systems and networks. A number of timed and stochastic extensions have been introduced for Petri nets. Stochastic activity networks (SANs) is one of these extensions that have been used in several projects for modeling and simulation in this area. We have recently introduced coloured stochastic activity networks (CSANs) as a high-level extension for SAN models. CSAN models can be evaluated by state space analysis techniques or discrete-event simulation. The usage of CSANs for network modeling and simulation has some key benefits over the other existing analytic and simulative techniques. To show these benefits, we have done a case study on modeling and evaluation of a switched LAN using a modeling tool called SANBuilder. In this paper, after an introduction to CSANs, we will present the CSAN models of the case study and the evaluation results.

On Calibration and Application of Logit-Based Stochastic Traffic Assignment Models
There is a growing recognition that discrete choice models are capable of providing a more realistic picture of route choice behavior. In particular, influential factors other than travel time that are found to affect the choice of route trigger the application of random utility models in the route choice literature. This paper focuses on path-based, logit-type stochastic route choice models, i...
