The production is exposed to a high coordination and communication needs due to the division of labor as a result of specialization. The indicators used for decision making often don’t have the same information base. With an information-based reorganization of tasks an increase of decision quality and speed is possible. © GITO Verlag.

Short-term, considerable need rises in the production require short-term capacity rises by capacity flexibility which is connected with a reaction time. In the context of a project sponsored by the German research council a possibility has been developed to bridge the reaction time by a short-term, article general reduction of outputs. © GITO-Verlag.

An empirical survey identifies the current status of logistic controlling in German small and medium-sized enterprises. The IPH elaborated practical requirements regarding the tasks and goals of a logistic controlling. The article describes the results of the survey towards acceptance, focus, as well as need for further development of logistic controlling. © GITO-Verlag.

Many forged parts e. g. connection rods or box spanners feature cavities, holes or apertures, which have to be produced in an additional process step (in many cases warm piercing). The residual material, that remains at the cross sectional area of the piercing punch, so called web, has to be pierced in an additional manufacturing step. By integrating this separately performed operation into the final forging step the process chain can be shortened. However, up to date there is no information available on how the process parameters influence quality relevant factors like dimensional accuracy, surface quality, and fibre orientation in the pierced area when forming and piercing operations are combined. Therefore, a combined forging-/piercing process was designed and performed in two projects. In the first project, not discussed in this paper, forging temperature, tool and work piece material as well as the thickness of the web have been investigated. The results of these investigations showed that the variation of the inserted mass and the forging temperature have a distinct effect on the dimensional and form accuracy of the work pieces. The second project investigated different geometries of the piercing punch and the influence of a different forming sequence on tool stress and material flow. The geometry of punch shows no effect on the geometrical tolerances of the piercing while an inappropriate forming sequence leads to failure of the tool. © 2010 German Academic Society for Production Engineering (WGP).

2012 International Conference on Indoor Positioning and Indoor Navigation, IPIN 2012 - Conference Proceedings | Year: 2012

Indoor positioning is an enabling technology for advanced intra-logistic applications that employ tracking and tracing of goods and vehicles. For these applications, a positioning technology must offer a sufficient trade-off between accuracy, range, and costs. In this paper we present a novel positioning system based on optical technologies that is designed for tracing vehicles in a logistic environment. The major innovations of the system are an active optical infrastructure allowing absolute positioning without any other data source, and, on the receiver side, a hybrid data processing approach that combines signal and image processing. Using these optical technologies, a high accuracy can be achieved at lower costs compared to other approaches. The static positioning error is below 0.1 m. The active optical positioning approach joins signal and image processing technologies to a low-cost and high accuracy system. While designed for intra-logistic applications the technology can be adopted other fields such as building and shop-floor navigation. © 2012 IEEE.
