To date, there are only sporadically implemented examples of Smart Factories and these are rather technically (specifically information technology) oriented. Phoenix Contact therefore decided to use a tailor-made approach to implement the digital transition towards becoming a Smart Factory. With the participation of the senior management affected, other internal support areas and the works council, an image of the future for the Smart Factory was developed. Based on the main future processes the appropriate organizational structure was selected and all participants could now be trained in the performance of new tasks. In addition, this allows for technological concepts to be chosen and judiciously incorporated in further stages. In this paper, the “SmartOrg@Combicon” project will be illustrated as the initial phase in the course of Smart Factory implementation. }}, author = {{Dobrzanski, P. and Jungkind, Wilfried}}, booktitle = {{Production engineering and management}}, editor = {{Villmer, Franz-Josef and Padoano, Elio}}, isbn = {{978-3-946856-03-0}}, keywords = {{Industry 4.0, Smart Factory, Digital transformation, Staff and organizational development}}, location = {{Lemgo}}, number = {{1}}, pages = {{147--158}}, title = {{{Human Resources and Organizational Development in the Context of Industry 4.0}}}, year = {{2018}}, } @inproceedings{686, abstract = {{A high level of productivity for current and future services is a critical success factor for companies.

If the major advantage of block storage in area saving is themost important, the companyhas to accept the removal principle of last in first out or in other words, first in last out. The last goods to be stocked are the first goods to be removed and the first stocked goods are the last to be removed. There are some special observations in the block storage concerned in this paper. The first one is that the goods in the storage ordered by the customers can often not be removed directly from the storage without any stock movement. Theaim is to not only benefit fromthe high-density storage solution but also decrease the negative influence of block storage, especially when pre-stocked goods must be removed at first. The second observation is that during one concerned time period, forexample, one day, there may be several operations of put-away and several operations of order picking for shipment preparation. The third observation is that before goods are put away to storage, which goods to be removed are not always predictable. The preplanned removal dates are quite often unexpected changed. In this paper, scenarios with different dynamic properties and stochastic probabilities have been concerned and defined. Strategies for the three main stages of put-away, i.e. stacking, pre-marshalingand retrieval are defined and examined developed. Simulations have been conducted to examine the strategies based on different scenarios. The aimis to select the right strategy which may reduce the overall relocation operations.

With the development of sensor technology, software engineering, andalgorithms, there is a spectrum of different navigation methods for AGVs. Inorder to avoid the additional environmental installation,so as to increase the flexibility of route planning, but to keep the positioning precision, more sensors, such as light detection and ranging (LIDAR), wheel encoders and gyroscope are installed on the vehicles to be automated. Some intelligent algorithms such as simultaneous localization and mapping (SLAM) algorithms and Monte Carlo localization have been developed for the navigation of vehicles, including position and orientation. The interesting question, especially for the AGVmanufacturers, is: which algorithm is more suitable for which kind of applications. The suitabilityof an algorithm for the navigation of AGVs with facilities of Light Detection and Ranging(LIDAR), encoders and gyroscope ismainly determined by four properties. They are the positioning precision, computational costs, execution time and positioning repeatability. This paper intends to investigate the suitability of an algorithm or a navigation method for AGVs with LIDAR, wheel encoders,and gyroscope. The two aspects of positioningaccuracy and repeatability are especially concerned. A general comparison of different navigation methods and algorithms is given. An experimental platform with a basic vehicle, controlling system and sensors is then developed to further evaluate the algorithms. The hardware components and software components are compatible to robot operating system (ROS). This open-source robotics middleware provides services and tools for creating robot applications.
