Die Geschäftsstellen müssen für die Zeitspanne der Euro-Bargeld-Einführung(17.12.2001 bis 28.02.2002) mit einem deutlich höheren Kunden- und Transaktionsaufkommenim Kassengeschäft rechnen. Damit weder chaotische Zuständemit langen Warteschlangen noch hohe Zusatzkosten die Folgen sind,...

Background: This study addresses optimising fleet size in a system with a heterogeneous truck fleet, aiming to minimise transportation costs in interfacility material transfer operations. Methods: The material transfer process is modelled using a closed queueing network (CQN) that considers...

For given external arrival process and given service-time distributions, the object is to determine the order of infinite-capacity single-server queues in series that minimizes the long-run average sojourn time per customer. We gain additional insight into this queueing design problem, and...

In this paper, we propose a fast adaptive importance sampling method for the efficient simulation of buffer overflow probabilities in queueing networks. The method comprises three stages. First, we estimate the minimum cross-entropy tilting parameter for a small buffer level; next, we use this...

In a companion paper we developed a unified scheme for using poststratified sampling and control variables to improve the efficiency of regenerative queueing simulations. We adapted these variance reduction techniques to the estimation methods of replication analysis and regenerative analysis by...
