In the presented article, the initial situation, which leads to the development of a small-scaled cyber physical material handling system, is presented first. Therefore, apart from the general requirements of material handling systems, the reasons for a determination of new requirements are presented as well. Since the developed system consists of multiple decentralized controlled conveyor elements, the data transmission principle inside the system will be described.

In this presentation the research project "Quality system for the evaluation of 8D report contents (QuSys)" was introduced. The objectives of the research project are the effective organization of complaint management and the internal fault management due to an automated quality evaluation of 8D reports. The evaluation allows to take well-directed measures and prevents that faulty 8D reports are sent to the customer.

The concept of angular difference allows simultaneous measurement of the relative and absolute rotation angle as well as the torque. The torsion of a shaft resulting from torque gets determined via the difference of two angles and converted into correlating torque. Today’s measuring devices use encoder disks or additional torque shafts. An incremental or absolute structure of measurement of the encoder disks is applied to it. Torque shafts are used frequently to extend the twist angle as a result of torsion. Current methods of measurement for rotation angle and torque are described.

In this paper an approach to establish a flow-production in the production of xxl-goods is presented. The developed approach is based on three sequentially steps and takes the specific conditions and characteristics of the xxl-production (e.g. high customization, highly scattering process times) into account. With the developed approach a safe forecast on the economic impact of a manufacturing reorganization is made, so that investments in failing reorganization attempts can be avoided.

Compared to conventional demolition processes (e.g. living houses) the demolition of industrial plants, such as nuclear power plants, is more challenging for the management of logistics processes (e.g. due to spatial and legal restrictions). Therefore the demolition of a nuclear power plant can take up to ten years and incur costs by 4 billion euros. Controlling the logistics processes can reduce these costs and the required time significantly.

Assembling large-scale products involves frequent process interruptions induced by e.g. delayed material deliveries or missing availability of resources. Our approach for identifying alternative assembly sequences by analyzing the product structure and process dependencies allows for continuing with the assembly process in case of interruptions and therefore increases the process efficiency.

This paper is concerned to technology trends in logistics and shows a user interface which is focused on voice commands for using it with automated guided vehicles (AGV). Furthermore a multimodal human-machine interaction (HMI) will be presented, which gives the user the possibility to communicate and control an AGV due to information from a speech recognition system and an electroencephalograph (EEG). It will be shown which potentials based on the merging between the acoustical voice signals and the non-invasive recording of the brainwaves from the EEG-Headset are available. By the detection of the cognitive and emotional state of the user from the signal curves by the EEG like attention or mental effort, an intelligent HMI should be realized. As a result, dialogues between humans and machines could be used more efficient and wrong inputs, like for example the request for a reconfirmation if an inattention is detected, could be reduced. First perceptions will be shown in this paper. In conclusion there will be a prospect of upcoming studies in the future.

This article presents a solution for the thermoelectric power supply of wireless sensor nodes for condition monitoring of marine gearboxes. Among the different ambient energy sources in marine gearboxes, frictional heat has been identified to be appropriate to thermally power a thermoelectric generator (TEG). The such generated electricity may power wireless sensor nodes for detecting temperature, vibration, torque and rotational speed. Requirements for a corresponding energy supply are formulated, constructive solutions are presented and thermal simulations and practical experiments are reviewed. The results are evaluated and a solution is selected for further implementation, which provides for an actively cooled TEG in the area of the ship gearbox’s heat exchanger. This can provide continuous electrical power of up to 14 mW, thus supplying the planned sensor nodes. The disadvantage of this solution is that a comparatively extensive mechanical modification, for example, to the oil and cooling water pipelines is required.

More and more people want to live in the cities. Space is getting scarce – not only living space but space for offices, streets, parking, railways and stations. Will urban infrastructure still be sufficient in the future? And how can we use urban space as efficiently as possible?

As a highly-loaded element between the diesel engine and propeller installation, the marine gear has a special significance with regard to the reliability of the entire ship propulsion. Together with project partners from industry and research a condition monitoring system has been developed by the IPH, to prevent failures. The peculiarity of the system is the wireless and self-powered operation.

When designing logistics processes, the demand for an environmental sustainability is increasing. Often companies have a choice between different alternatives, which costs and environmental consequences may differ. This paper presents the results of a research project that aimed to develop a method for the ecological and cost-based selection of supply concepts.

The method of injection molding is one of the most important processes in the processing of plastics. Thus moldings can be produced economically in large quantities and with a high reproducibility. Besides quality the energy consumption in the production is an important part because of the energy transition and the rising energy prices. In particular, small and medium enterprises from the plastics processing industry in Germany with about 3,000 companies are, therefore, forced to optimize their processes and production equipment energetically.

Path-finding algorithms (PFA) are successfully used to find the optimal path between two locations. Good results are obtained if they are used in scenarios where the entire environment can be described mathematically. Production environments of automated guided vehicles (AGVs) are not one of those. PFA find solutions that are mathematically correct but miss human expertise that would dismiss solutions of the algorithm that aren’t applicable to a real production layout. This paper presents a hybrid algorithm consisting of an A* algorithm, and a fuzzy logic control in order to generate a fuzzy-enhanced A* algorithm (FEA*) that produces efficient and applicable road maps for AGVs. First computational results are shown.
