Stability of queueing-inventory systems with different priorities
Sonja Otten, Hans Daduna
We study a production-inventory system with two customer classes with different priorities which are admitted to the system following a flexible admission control scheme. The inven…
Load balancing in a network of queueing-inventory systems
Sonja Otten
We study a supply chain consisting of production-inventory systems at several locations which are coupled by a common supplier. Demand of customers arrives at each production syste…
Exponential single server queues in an interactive random environment
Sonja Otten, Ruslan Krenzler, Hans Daduna +1
We consider exponential single server queues with state-dependent arrival and service rates which evolve under influences of external environments. The transitions of the queues ar…
Lost-customers approximation of semi-open queueing networks with backordering -- An application to minimise the number of robots in robotic mobile fulfilment systems
Sonja Otten, Ruslan Krenzler, Lin Xie +2
We consider a semi-open queueing network (SOQN), where a customer requires exactly one resource from the resource pool for service. If there is a resource available, the customer i…
Randomization for Markov chains with applications to networks in a random environment
Ruslan Krenzler, Hans Daduna, Sonja Otten
We develop randomized modifications of Markov chains and apply these modifications to the routing chains of customers in Jacksonian stochastic networks. The aim of our investigatio…
