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...

Dispatching rules are simple but efficient heuristics to solve multi-objective job shop scheduling problems, particularly useful to face the challenges of dynamic shop environments. A promising method to automatically evolve such rules represents genetic programming based hyper-heuristic...

Material handling systems (MHS) are integral to logistics functions by providing various supports such as handling, moving, and storing materials in manufacturing and service organisations. This study considers determining the optimal size of a homogeneous fleet of trucks to be outsourced (or...

Noch effizienter agieren - Prozesse der Intralogistik optimieren.Über 50 Prozent der Unternehmen planen ihre Prozesse zu optimieren und in die Digitalisierung zu investieren.Dieses Buch bietet einen Leitfaden, um die Effizienz in der Intralogistik zu steigern und im besten Fall auf ein neues...

The paper at hand presents a definition of autonomous intralogistics systems and a classification of intralogistics systems with regard to their degree of autonomy. Intralogistics − a complex interplay of different logistics functions − covers the organization, control, execution and...

With the application of in-house logistics automated guided vehicle (AGV) systems for transportation three different control problems arise: task assignment, empty vehicle balancing and routing. With an increasing fleet size and especially when considering requirements like flexibility and...

Logistics commands a huge variety of dynamic developments, driven by technological, organizational and market changes. In particular, automation and ergonomics are promising means to increase economical, ecological and social sustainability. The publication of this research paper marks...
