Utilization is one of the main managerial factors that is applied for construction process analysis well. It directly affects the project duration and construction costs. Therefore, a utilization study in tunneling projects is essential. In this work, the utilization of an earth pressure balance Tunnel Boring Machine (TBM) in Tabriz urban railway project was studied using the Monte Carlo simula...

introduction: due to the large number of pet systems available in the market, it is not very easy to decide about the scanner of choice. conducting a research in order to compare all different pet scanners is very time consuming and expensive and practically impossible. however, such comparison may be conducted using pet simulators. in this study, the performance of 6 different pet scanners in ...

Although the software tools to develop simulation models have improved dramatically, relatively little has been written about how to most effectively exercise those models. This paper provides warnings and suggestions to improve simulation studies. Although based primarily on the authors’ experience with discrete-event models in manufacturing situations, many of their observations are more wide...
