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...

Problem definition: The configuration of an emergency vehicle fleet (EVF) is critical to ensure that responders have the resources necessary to serve emergencies quickly and help prevent loss of life and property damage. Determining the fleet’s optimal design involves decisions regarding the...

This paper investigates a scheduling approach for Automated Guided Vehicle Systems, enabling transport load transfers between vehicles during transport execution. The vehicles can use predefined transfer stations to buffer transport loads until the transport continues by a following vehicle. The...

Background: The key performance index for the container terminals is the vessel berthing time which is highly affected by the scheduling of the different handling equipment. Proper integrated scheduling of the handling equipment is crucial, especially in automated container terminals, where all...

Background: This paper aims to improve the overall performance of manual warehouse Order Picking (OP) processes by proposing an innovative method for designing a picking area layout, and introducing a storage assignment strategy with respect to ergonomics and workers' physical fatigue. Methods:...

Steigende Herausforderungen, wie z.B. ein intensiver Wettbewerbsdruck hinsichtlich Innovationen und eine damit einhergehende Individualisierung der Produkte sowie eine steigende Internationalisierung führen zu einem Wandel in der Automobilbranche. Die Kombination der Faktoren führt zu einem...

Production in industrial companies is exposed to more and more frequent cycles of change, while at the same time, the market demand in terms of flexibility, high logistical performance and low costs are constantly increasing. Production systems must thus be designed to be capable of change. In...
