@inproceedings{576, abstract = {{Due to a high level of competition in automotive industry, it is essentially important for automotive companies to develop innovative strategies and technologies in production and logistics. Postponement of production difference, i.e., customer individualized demand has been considered as an innovative strategy and more or less implemented in the production process, mostly before and during the final assembly. This paper proposed the concept of postponing the individualization of some components after the assembly. The idea is to use the idle times especially during the distribution process when vehicles are accumulated to generate big transportation batches or the follow-up transport does not start immediately. The individualization is carried out in specially realized workshops. Objectives of the approach are to reduce variations in the manufacturing, to shorten delivery times and to give consumers the ability to reorder individual components shortly before delivery. This kind of postponement of individualization induces the requirement of redesigning the logistics network, which means the selection of workshop locations and the new selection of the suppliers for the individualized components. To reach this aim, a software tool has been developed. In the tool, the data required in the logistics network such as suppliers and workshop potential locations are managed in a MySQL database and the optimization of the network is achieved by the especiallydeveloped non-dominated sorting genetic algorithm-II (NSGA-II). The design and development of the solution individuals and the fitness functions, which are the most important elements of a genetic algorithm, are based on the mathematical model of the logistics network design with product late individualization. Different scenarios are considered and generated to examine the applicability of the methodology in automotive practice. The optimization model and the heuristics of genetic algorithm are validated through the Pareto solutions for different scenarios.}}, author = {{Li, Li}}, booktitle = {{Production Engineering and Management}}, editor = {{Padoano, Elio and Villmer, Franz-Josef}}, isbn = {{978-3-946856-01-6}}, keywords = {{Automotive industry, Logistics network configuration, Late product individualization, Postponement, NSGGA}}, location = {{Pordenone, Italy}}, number = {{1}}, pages = {{139--150}}, title = {{{Optimization of Automotive Logistics Network with Late Product Individualization}}}, year = {{2017}}, } @inproceedings{328, abstract = {{In this paper, concepts for an extended DC network for the main power supply of components from various manufacturers in industrial production are presented.

As far as AC/DC conversion is concerned, the advantages and drawbacks of several rectifier topologies are listed, as they have a significant impact on the system behavior and EMC properties.

The reduction of energy consumption results from the interaction of optimized components (motors, control techniques and regeneration units), which are described in detail in this paper. Different motor concepts like the induction motor, the synchronous reluctance motor and the permanent magnet synchronous machine are compared according to the special requirements for intralogistics applications. Different control techniques are presented in order to achieve sensorless and efficient-optimal operation of these motors. The sensorless control technique uses signal injection to detect the rotor position sufficiently exact also in case of speed near standstill. Efficient-optimal operation is achieved by reducing the motor current with regard to the torque (MTPA-control). Furthermore this paper introduces a regeneration unit that can be connected between the DC link of frequency inverters and the mains to feed back regenerative energy. The regeneration unit consisting of a buck converter, a synchronous inverter and a line-filter can work in parallel to commonly used uncontrolled rectifiers. Its functioning is shown with the help of measurement results of a 1kW laboratory prototype. The last section shows a demonstrator in which a conventional conveyer system (with induction motor and braking resistor) is compared with an optimized one using the presented components. Power versus time measurements show specific energy savings resulting from the interaction of the optimized components.}}, author = {{Austermann, Johann and Borcherding, Holger and Stichweh, H. and Grabs, Volker}}, booktitle = {{2016 18th European Conference on Power Electronics and Applications (EPE'16 ECCE Europe)}}, isbn = {{978-3-8007-4186-1}}, keywords = {{electric current control, induction motors, invertors, permanent magnet motors, reluctance motors, sensorless machine control, torque control, modular solution kit, intralogistic drives, automated warehouse, energy consumption reduction, optimized components interaction, induction motor, synchronous reluctance motor, permanent magnet synchronous machine, sensorless control technique, signal injection, rotor position, motor current, MTPA-control, regeneration unit, DC link, frequency inverters, buck converter, synchronous inverter, line-filter, Induction motors, Reluctance motors, Permanent magnet motors, Rotors, Torque, Inverters, intralogistics, reluctance motor, sensorless control, regeneration unit, braking energy}}, location = {{Karlsruhe}}, pages = {{1639--1646}}, publisher = {{VDE Verlag}}, title = {{{High Efficient Modular Drive System - An Ideal Approach for Green Intralogistics Applications}}}, doi = {{10.1109/EPE.2016.7695687}}, year = {{2016}}, } @inproceedings{4330, abstract = {{Catchwords such as “Cyber-Physical-Systems” and “Industry 4.0” describe the current development of systems with embedded intelligence.
