Performance evaluation of shuttle-based storage and retrieval systems using discrete-time queueing network models

Produktform: Buch / Einband - flex.(Paperback)


Shuttle-based storage and retrieval systems (SBS/RSs) are an important part of today‘s warehouses. In this work, a new approach is developed that can be applied to model different configurations of SBS/RSs. The approach is based on the modeling of SBS/RSs as discrete-time open queueing networks and yields the complete probability distributions of the performance measures.

Discrete Time Analysis of Multi-Queue Systems with Multiple Departure Streams in Material Handling and Production under Different Service Rules

Produktform: Buch / Einband - flex.(Paperback)


In this work, we present a modelling approach in order to depict service rules holistically. The developed model is called multi-queue system with multiple departure streams (MQSMDS). The MQSMDS is modelled as a discrete time Markov chain. On the basis of a numerical study, the system characteristics are evaluated. The results of this work enable a rapid and low-cost analysis of material handling and production systems as well as a fast and easy identification of suitable service rules.

Entwurfsmuster für Fahrerlose Transportsysteme

Produktform: Buch / Einband - flex.(Paperback)


Fahrerlose Transportsysteme (FTS) sind eine flexible Alternative zu starrer Fördertechnik. In dieser Arbeit werden Probleme und Lösungsansätze zur Gestaltung von FTS in Form von Entwurfsmustern aufgezeigt. Die Muster betrachten die Themen Modularität, Sicherheit, Mensch-Maschine-Interaktion, Navigation und dezentrale Steuerung. Sie dienen einerseits der Strukturierung von Lösungsansätzen und sind andererseits ein Hilfsmittel zur Entwicklung Fahrerloser Transportsysteme. Automated guided vehicles (AGVs) are a flexible alternative to rigid conveyor technology. Based on challenges of AGVs, this work presents corresponding design patterns. The patterns consider the topics modularity, safety, human-machine interaction, navigation and decentralized control. On the one hand, they serve to structure solutions and on the other hand, they facilitate the development process of automated guided vehicles.

Milk Run Design: Definitions, Concepts and Solution Approaches

Produktform: Buch / Einband - flex.(Paperback)


Efficient inbound networks in the European automotive industry rely on a set of different transport concepts including milk runs - understood as regularly scheduled pickup tours. The complexity of designing such a mixed network makes decision support necessary: In this book we provide definitions, mathematical models and a solution method for the Milk Run Design problem and introduce indicators assessing the performance of established milk runs in relation to alternative transport concepts.

Design for Stability in Transport Logistics - Definition, Concepts and Evaluation

Produktform: Buch / Einband - flex.(Paperback)


Lean management describes a set of methods combined with a management philosophy which aims at eliminating waste in logistics processes. In production logistics, lean is already widespread and applied successfully. Research has shown that lean also works in a warehousing environment. In transport logistics, lean is still at a low level of maturity in both research and practice. This work contributes to closing this gap by introducing Heijunka leveling to transport logistics.

Logical Time for Decentralized Control of Material Handling Systems

Produktform: Buch / Einband - flex.(Paperback)


The fourth industrial revolution aims to transform production systems. In this work, Logical Time which is a control principle for distributed systems is transferred to material handling systems with decentralized control. The GridSorter, a modular sorter with grid-like structure, is chosen as showcase system. The system is proven to be deadlock-free and is robust against varying transport times. The time-window-based route reservation process is described as Iterative Deepening A*.

Travel Time Models and Throughput Analysis of Dual Load Handling Automated Storage and Retrieval Systems in Double Deep Storage

Produktform: Buch / Einband - flex.(Paperback)


A general analytical travel time model for the quadruple command cycle in double deep storage systems with a dual capacity load handling device is formulated and validated by means of a simulation model. Various routing and sequencing strategies are composed. A simulation model is used to compare strategies for differnt AS/RS configurations and settings to assess them in consideration of real-world cases. For selected strategies, analytical formulations are derived.
