Automated guided vehicle systems (AGVS) are a vital component for efficient production systems in connection to intra logistics and essential for parts of the internal material handling, so they could not imagine living without them. The essential function of an AGVS is to control the automated guided vehicles (AGV), which are able to provide with application-specific load handling devices like telescopic forks or lifting tables, automatically. AGV could be used in different parts of applications like for example the transport of pallets, assembly or commissioning. The motivation of this project is to develop a new market for competitive autonomous transport systems. Economic forklifts should be created by technological development to handle logistical subtasks, like transferring goods, commissioning and transporting, autonomously.

A xxl-product is defined as product, whose production costs increase disproportionately in relation to further growth of a characteristic product feature. Existing models of supply chain design are not designed for xxl-products. For this reason a method was developed to create a supply chain for a xxl-product. The supply chain design works in due consideration of the most relevant xxl-product specific features. The created supply chain can be evaluated for their logistical quality. Therefore a comparison between different supply chain variants is possible.

The assembly of complex, large-scale products is often characterized by poor date availability, limited process standardization, frequent product modifications and flexible usage of resources, which often leads to interruptions in the assembling process. Therefore, in a research project between the IPH Hannover and the WZL of RWTH Aachen University, a methodology for assembly processes is developed which allows the identification and evaluation of process alternatives in case of interruptions. For the evaluation of those process alternatives logistical objectives are used.

In this study two approaches in automotive lightweight construction have been combined: weight reduction based on material and based on structural design. Steel and aluminum are used for the first approach, and hydroforming is the method for design optimization by shaping. Steel and aluminum show different forming behaviors due to their characteristic yield stresses. The challenge in developing a hydroforming process for THTs is to provide feasible forming conditions for both the steel and the aluminum part. Forming tests were carried out on sheet metal specimens of laser brazed and laser soldered steel and aluminum to investigate the impact of specific parameters and to analyze the joint area’s forming behavior. An FEA simulation was set up in order to design a tube hydroforming process for THTs of laser joined steel and aluminum. Eventually, the hydroforming process for THTs will be designed and executed.

The project REFoCh is about resource efficient forging of complex high duty parts, e.g. crankshafts. Within this project founded by the European Union, a new process chain for a crankshaft will be developed with the aim of reducing the flash quota significantly. In the conventional forging sequence, 54 % flash occur, the aimed flash quota is 15 %. To reach this objective, a multidirectional forging step will be implemented in the new process chain in order to reduce the material significantly.

The material costs represent up to 50 % of the total production costs. By decreasing the flash ratio the material usage and production costs in forging operations can be reduced. For complicated forging parts the development of a new forging sequence is necessary to achieve a flash reduced forging sequence. This development was performed for a two-cylinder crankshaft. The new flash reduced forging sequence is using flashless preforming operations, an induction reheating of the preformed complicated work piece and a flash reduced final forging. With the reduction of the flash ratio from 54 % down to 10 % the total energy consumption was reduced and the competitive capacity of forging SME’s is increasing.

Data analysis on a microcontroller in the immediate vicinity of the measuring point creates an intelligent sensor node that enables a condition prognosis of gearbox components. The IPH compares different approaches of analysis regarding computing time and energy consumption in order to minimize the effort of wireless data transmission.

The production ramp-up is often a critical period for manufacturing companies. It is essential to prepare an efficient plan and to monitor consistently the abidance of this plan. Generally processes and activities can be monitored with key performance indicators. This article describes an approach to identificate key performance indicators for the monitoring of additional production capacities at new locations.

The generation of road maps for automated guided vehicles (AGVs) in the area of logistics is increasing in complexity as a result of the changing production environment. Reasons for that are the shorter product life-cycles and the advances in the field of AGVs. So far, the generation of roadmaps for AGVs is a manual task and is therefore time-consuming and expensive. Information from different sources (e. g. the production layout and the transport matrix) have to be evaluated and be joined. A simplification offers the storage of expert knowledge of system planers in a form of artificial intelligence in a fuzzy-rule base. This concept is going to be realized in a software tool that is going to be able to automatically generate roadmaps for AGVs.

Companies are confronted with a business environment that is becoming more and more turbulent. As a result the load spreading increases. The causing factors and what actions a company can do in order to overcome those problems are unknown. This article deals with the identification of potential influence-parameters on load scattering and their mapping in a simulation-model in order to determine the effects of these parameters on load spreading.

Economic growth in Germany and Europe secures jobs and prosperity. However, the impacts on our environment are often negative. Because more goods are produced and the consumption increases, traffic and thus the greenhouse gas emissions rise. In order to keep these emissions as low as possible, the stated goal is to shift transport from road to rail. Thats why many terminal stations are preparing for rising turnover figures. However, the problem of maximizing throughput capacities is unsolved. To answer this question, the IPH has developed an innovative, event-discrete model used in a material flow simulation based on the software Plant Simulation.

The industrial production process is subjected to a high coordination and communication needs arising from the division of labor as a result of specialization. Trade-offs are omnipresent. For decision making the used indicators often do not have the same information base. The information-based reorganization of tasks can help here. The aim is to increase the decision quality and speed.

Manufacturing companies are forced to reduce their energy costs because of rising electricity tariffs. Due to the increasing volatility of energy rates so far unused potential arises. As a sub-discipline of production planning and control the manufacturing control determines the temporal process of work orders and has great impact on the energy costs of the production. This article describes the approach of an energy cost-efficient manufacturing control, taking account of the established targets.

When designing delivery concepts, companies often have a choice between different alternatives. The decision between these alternatives is no longer made only on their costs and logistical efficiency. Rather the ecological compatibility of the processes is more and more considered. This paper introduces ways to integrate environmental sustainability into decision-making.
