KiNaLog Customer-specific Sustainable Logistics Durch den Online-Handel gewinnt die Konsumentenlogistik zunehmend an Bedeutung, speziell im Bereich der sog. „letzten Meile“. Besonders herausfordernd ist dabei die Lebensmittellogistik, da es sich hierbei oft um zeitkritische Transporte handelt und sowohl spezielle Transportverpackungen für gekühlte oder tiefgekühlte Produkte notwendig sind als auch zusätzliche Verpackungen für die kundenindividuelle Kommissionierung verwendet werden müssen. So ergibt sich ein Konsumentendilemma, bei dem der Komfort einer Online-Bestellung inklusive Lieferung den hierdurch entstehenden CO2-Emissionen und Verpackungsabfällen gegenüberstehen. Bis dato gibt es jedoch keine Möglichkeit, dem Konsumenten die direkten und indirekten Auswirkungen seines Handelns im Moment der Bestellung aufzuzeigen, sodass eine bewusste Wahl nachhaltiger Optionen heute noch nicht möglich ist.

Manufaktur 4.0 Quality-oriented production control and optimization in food production The project develops a digitalised, quality-based production planning and control system for food production. The system focus on an optimal use of raw materials (e.g. reduction of the storage time of sensitive raw materials). The development should lead to a better operating grade of the production facilities and an optimization of their energy consumption as well as to an optimized bin management and especially to an increase of the product quality (taste). In order to achieve the objectives, raw material-specific quality-time profiles will be analysed and integrated in an IT-based procedure for quality-oriented production planning and control, which will be implemented as a prototype by the project partner.

VR-SUSTAIN Simulation-based training for accident prevention in the automotive industry In the VR-SUSTAIN project, a training environment is developed, which familiarises trainees and skilled workers in a safe environment with the prevention techniques of accidents and damage to manufactured products. Virtual Reality (VR) is applied to provide the participants with an interactive, immersive learning experience. Two learning scenarios are developed: the prevention of health risks, scratches and dents in the manufacturing process as well as the prevention of accidents when handling electrical equipment. The VR-SUSTAIN project aims to improve the training quality and efficiency in both learning scenarios through innovative VR technology. Besides training to reduce product damage and injuries, the application increases the media competence of trainers and participants. Furthermore, the project intends to gain essential insights into the development and implementation of VR-based training in the European manufacturing industry. Contact persons: B.

AxIoM Gamified AI Assistance System for Support of Manual Assembly Processes In this research project, a novel assistance system for manual assembly stations based on artificial intelligence will be developed. On the one hand, the system monitors the assembly process and verifies the quality of the completed product, and, on the other hand, it considers and individually supports the employee when working at the manual workstation. The system will analyse the sensory information collected at the assembly station using image processing and machine learning methods with regard to the ergonomic and production-related work situation of the employee. This enables the newly developed assistance system to adapt to the individual needs of the employee in order to improve his work situation through specific support as well as motivation and training strategies. Furthermore, by monitoring both progress and assembly components, the system will increase the efficiency and quality of the manual assembly process. Contact persons: C. Petzoldt (Project manager)T.

OffshorePlan Complementary application of mathematical and discrete-event models to solve complex planning and control problems in offshore construction logistics Offshore construction logistics pose an exceptionally challenging problem in terms of planning and control. Generally, one can differentiate two approaches: event-discrete simulations as well as mathematical or stochastic optimizations. By themselves, both methods provide their own advantages and disadvantages in terms of computational time, level of detail und optimality. This project aims to investigate new ways for the complementary utilization of both types of methods in the context of offshore construction logistics. Under the basic assumption that despite formal differences, both types of models describe the same elements of the real world system, this project aims to develop a method to convert in between or to generate each kind of model with its own level of aggregation/abstraction based on a more basic description of the real world system. Consequently, the advantage of both types of models can be used complementary within computer aided planning and control methods. Contact persons: M. Lütjen (Project manager)D.

LNG Armaturen Set Development of a sensitive valve set for high-volume ship to ship LNG transfer The project aims at the development of a system which can be used on a large number of different ship types and thus leads to a significantly higher level of safety, installability and maintainability while at the same time reducing costs. The task of BIBA is to develop an Augmented Reality (AR) solution that can be used for maintenance and service purposes alongside the valve set. By means of a combination of a commercial data goggle, a camera and an embedded PC, an easily configurable application solution is created. This solution should be able to identify the existing components, to read out the corresponding status information both visually and via radio, and to supply the users with maintenance information and checklists. The AR solution will be developed to support technicians in operation, installation and maintenance of the sensitive LNG valve set. By means of image processing and object recognition techniques, the first step is to collect information on the condition of the valves. Subsequently, an AR-User Interface will be developed, which acts as an assistance system for the users. Contact persons: H.

LNG Safety Safety process system for cryogenic fluid transfer The handling of cryogenic fluids (e.g. liquefied natural gas) bears major risks with regard to operational safety. If the liquid leaks during a transfer process (e.g. fueling of ships), large amounts of gas can quickly be produced which are highly flammable and explosive. Therefore, an appropriate safety system for process monitoring is necessary. The aim of the project is to improve operational safety during the LNG transfer process by means of a redundant optical monitoring system. This system should be able to both detect fittings, ship superstructures, and people automatically and to perform an automated visual inspection of the correct coupling. The multi-camera system consists of a wide-angle, a zoom and an infrared camera and can therefore react to a wide variety of environmental conditions (day, night, weather influences). It automatically monitors the LNG transfer process. By using Deep Machine Learning, the object recognition of fittings, ship superstructures and people is made possible, which is necessary for monitoring the danger zone. Contact persons: H.

IPM Individual Predictive Maintenance Ziel des Projektes ist die Entwicklung einer Toolbox zur Ãœberwachung von Sensordaten für eine individuelle prädiktive Instandhaltung von Dieselmotoren für Schienenfahrzeuge. Motivation: Derzeit werden Instandhaltungsmaßnahmen reaktiv oder in periodischen Intervallen präventiv durchgeführt. Dieses Vorgehen ist jedoch mit hohen Kosten verbunden, da im Schadensfall meist Folgeschäden auftreten. Zudem führen die ausgefallenen Züge nicht nur zu Verspätungen der darin transportierten Personen und Güter, sondern blockieren auch die Bahnstrecke für weitere Transporte und die damit zusammenhängende Logistikkette. Allerdings ergeben sich durch das vorsorgliche Austauschen der Komponenten relativ hohe Instandhaltungskosten, da diese noch für einen längeren Zeitraum hätten genutzt werden können. Methodik: Durch eine Instandhaltung im Bedarfsfall (kurz vor Störereignis) können die Instandhaltungskosten minimiert werden, ohne das Risiko eines Zugausfalls signifikant zu erhöhen. Unter Anwendung künstlicher Intelligenz sollen frühzeitig auszutauschende Motorkomponenten identifiziert und damit eine ressourceneffiziente Instandhaltungsplanung ermöglicht werden.

DPNB Dynamic Production Network Broker **Motivation** Fully dynamic cross-company production networks that adapt to individual customer orders are a core vision in the Industry 4.0 sector. Production capacities are sometimes required at very short notice, e.g. in the area of drawing and special parts. Reasons are the failure of company owned machines or machines of a supplier, the complete failure of a supplier or also a sudden increase on the demand side. In these cases, however, there are barriers to a rapid response, such as finding one or more suppliers with free capacities or the high manual effort required to integrate new suppliers into existing ordering and logistics processes. **Goal** The "Dynamic Production Network Broker" is intended to support the dynamic formation of production networks by means of a modular service system. This includes the matching of supply and demand for short-term availability of production capacities while at the same time ensuring the necessary transport capacities, the short-term onboarding of suppliers, i.e. rapid integration production, logistics and quality assurance and the possibility of making complex assembly activities compatible for outsourcing. The latter should be achieved by means of an assistance system that is based on Augmented Reality (AR) technologies. BIBA will contribute to the project by developing an ontological description of machine capabilities and requirements, including a semantic mediator with the necessary interfaces to other information systems. Moreover, we will develop a concept for generic service-based business models and their evaluation on the basis of the project results. **Procedure** Together with the industrial partners, the crucial points for designing a production network broker are worked out and on this basis four use cases are defined. For these four use cases, "Minimal Viable Products", i.e. prototypical solutions that can be implemented quickly, are developed in individual modules and later integrated into a continuous process.

EILa Examining the influence of „Industry 4.0“ on Factory Layout Planning In the context of ongoing industrial digitization, new technologies are introduced to make production processes more efficient. However, the digital data, which are created and processed by cyber-physical systems, promise improvements as well for adjacent areas, e.g. the restructuring of factories. Thus, the trend towards "Industry 4.0" influences factory planning and requires adapted methods for this task. In this project, the prospects of digitized factory planning are identified and examined, based on a literature study as well as an empirical investigation . The results will provide a methodical guideline for state-of-the-art factory layout planning and identify further research areas for adaptable digital factories. Contact persons: M.

ReaLCoE Next Generation 12+MW Rated, Robust, Reliable and Large Offshore Wind Energy Converters for Clean, Low Cost and Competitive Electricity Offshore wind energy is a key technology for generating renewable energies. Due to its complex processes regarding installation, operation and service, and therefore relatively high costs, offshore wind energy converters still cannot compete with today’s energy market prices. To create a competitive offshore WEC with a Levelised Cost of Electricity (LCoE) target of €35/MWh ReaLCoE takes a holistic approach and scrutinises costs in each link of the value chain. As a key element of ReaLCoE, BIBA focusses on the digitisation of future offshore WECs and their adhered value chain. Besides the integration of sensors and the implementation of a condition-based monitoring system, the digital representation of the WECs through a digital twin (“product avatar”) takes a major part in BIBAs contribution to ReaLCoE. Building on this, a concept for predictive maintenance will be developed and realized. Furthermore, BIBA will develop optimised logistic and installation concepts and will conduct various performance simulations for a further reduction of supply chain and installation costs. To validate the concept, a technology platform for a first prototype of a digitised 12+MW turbine as well as a pre-series array of 4-6 WEC will be installed, demonstrated and tested.

PiB Predictive and intelligent technical operation to reduce the risk of icing of wind turbines - Data Mining and Data Analytics Structural loads do not only stress wind turbines and rotor blades, they are also affected by extreme environmental influences. Depending on the location of the wind turbine, there is a risk of icing at the leading edge of the rotor blades, in particular at low temperatures and high atmospheric humidity. Within the PiB project, a predictive and intelligent technical operation to reduce the risk of icing of wind turbines will be investigated. Therefore, a new, comprehensive approach based on data mining and data analysis is adopted. In this concept, historical data, meteorological data, and lifecycle data in addition to the current SCADA data is considered. In addition, the innovative system is not limited to one wind turbine or one wind farm. Furthermore, it is planned to enable networking with other wind parks. As result, it is intended to provide a comprehensive picture of the individual risk of icing for each wind turbine. Contact persons: J. Ohlendorf (Project manager)A. Ait Alla M. Kreutz K.

LoRaLight Development of a highly flexible picking system Picking is a core process of intralogistics tasks and pursues the goal of compiling deliveries according to customer order; the deliveries are thus subsets of the entire product range. The installation of complex and wired infrastructure systems that supports efficient picking procedures is expensive and also poorly adaptable to a changing warehouse infrastructure. An additional problem in the area of ??quality assurance of the picking process is the monitoring of the correct picking processes (picks). This is especially true when picking from non-sorted subjects has to be executed as well as the simultaneous processing of multiple orders, in which an item that has been picked takes place in order-specific containers on a picking trolley. In the project, this gap is to be closed by developing a picking system that can be easily and inexpensively integrated into an existing warehouse infrastructure, maintaining a high degree of flexibility of adaptation and ensuring high quality standards. The maintenance effort should also be significantly lower than with conventional wireless systems. The system to be developed represents a deliberate departure from the development trend of continuous automation of warehouses and picking processes. Contact persons: M. Trapp (Project manager)M.

F.I.T. Gaerautomat Development of a fully automatic fermenter with automatic determination of the fermentation state In industrial bakery production, a lot of time is spent on determining the optimum fermentation state by baking experts. Achieving the optimal fermentation state purely on the fermentation time and ensuring compliance with the machine-side fermentation and cooling parameters is thus impossible in both branch operation and in industrial operation according to current state of development. The project develops a novel fermentation system (fully automatic proofer) with integrated measuring technology and a special software solution, that detects the current maturity automatically and reproducibly without having to interrupt the fermentation process. The system should be cost-effective, adaptable (large product range) and easy to use. Additionally, the system should be able to specify process leveling. Contact persons: J. Arango Castellanos M.

IRiS Interactive robotic system for unloading of sea containers The unloading of containers is one of the last non-automated activities in a highly-engineered transport chain. A significant proportion of imported and exported containers are emptied or loaded in seaports. Existing automatic and semi-automatic systems do not meet the requirements of port operators due to high investment costs, high commissioning times and adaptations to the infrastructure and have a very low degree of dissemination. The objective of the IRiS project is the development of a new, mobile robot for improving the efficiency of transhipment processes at seaports. The robot should be able to be deployed in a very short time without any major adjustments to the existing operational infrastructure. In order to be able to meet disturbing situations as quickly and effortlessly as possible, an intuitive human-robot interaction interface is developed. Contact persons: T. Beinke (Project manager)N.

Isabella Automobile logistics in sea- and inland ports: interactive and simulation-based operation planning, dynamic and context-based control of device- and load movements The project Isabella aims at the development of an interactive planning and control system for adaptive logistics processes on sea and inland ports. After development, the planning and control system will be implemented for pilot testing on the vehicle port of the BLG in Bremerhaven. A simulation-based planning tool will be developed to enable short-term planning adjustments due to occurring change demands and to validate possible planning alternatives. The planning tool is supposed to work on a visual and thus most intuitive basis. A multi-touch table will be used for the visualization of the current planning situation and the definition of planning alternatives. The evaluation of these alternatives is supposed to happen simulation-based. The simulation will evaluate all alternatives based on a multi-criteria target system. A control algorithm will be developed for the management of vehicle movements on the vehicle port. The control system should assign tasks based on the current order situation and the location of the vehicles. By doing so, not only a given order sequence and thus due date reliability can be pursued, but also route optimization and elimination or minimization of empty runs. For the realization of adaptive logistics processes, a tracking and tracing system needs to be designed that generates real time data of the location of the vehicles. A special requirement is the urgent need for a high spatial accuracy that can locate objects within an area of adequate size, preferably on parking lot exactness. Therefore, it will be investigated, if different tracking and tracing methods such as differential-GPS (DGPS) and WLAN-Fingerprinting are adequate for usage in vehicle compound applications. The envisioned planning and control system will be developed in cooperation with the project partners BLG and 28Apps. The project is funded by the German Federal Ministry of Transport and Digital Infrastructure (BMVI) as part of the program for innovative port technologies (IHATEC). Contact persons: S.

safeguARd Augmented Reality-based assistance system for commercial vehicles to raise the safety level The goal of the safeguARd project is the development of an assistance system for commercial vehicles, which recognizes the occurrence of hazardous situations at an early stage, draws the operator's attention to the dangerous situations and, in the last resort, actively transmits control commands to the machine operator, for example, to initiate an emergency stop. In the context of the project, the safeguARd system is initially developed and evaluated on the example of mobile cranes. This is due to a modular and flexible design so that the transmission of the system to other construction machines as well as other commercial vehicle groups is possible without major adjustments. The project partners apply the "Design for all" concept as part of the development efforts. Thus, the system enables all users to an efficient and safe use of commercial vehicles. Particularly older employees can compensate sensomotoric restrictions and thus the safeguARd system represents an approach to adapt machine operator workplaces to the requirements of the demographic change.

STRADegy STRADegy – Automated Container handling by Using Straddle Carriers The overall objective of the project STRADegy, which is conducted by EUROGATE and BIBA, is to increase the productivity and flexibility in container handling as well as to reduce the environmental impact and to increase the security of German seaports. Within the project, automated straddle carriers are evaluated in a field test in Europe for the first time. A straddle carrier is a highly flexible freight-carrying vehicle used for stacking and moving standard containers in container terminals. To achieve the research objectives, different concepts are evaluated to ensure a high productivity of the automated system. The developed concepts should also be applicable to a broad range of container terminals. For this purpose, standard interfaces have to be developed to link IT systems from different manufacturers, such as terminal operating systems (TOS), which control the handling processes in terminals. It is also important to ensure that straddle carriers from different providers can be integrated. In this context, BIBA contributes to the design of the pilot experiments and ensures that innovative research approaches are considered throughout all phases of the project. Furthermore, guidelines are prepared that will help to automate mega container terminals in the future. The flagship project STRADegy receives funding from the Federal Ministry of Transport and Digital Infrastructure (BMVI) as part of the program for innovative harbor technologies (IHATEC).

AdaptiveSBO An adaptive simulation-based optimisation approach for the scheduling and control of dynamic manufacturing systems **Motivation** The planning and control of production processes has a significant influence on the performance of a job shop manufacturing system. The job shop production is subject to dynamic influences (e.g. faults caused by machine failures or rush orders), which have to be considered for the production planning and control. Common methods are therefore normally divided into modules for calculating plans and modules for operational control. In general, optimisation only takes place at the strategic planning level, while detailed planning is carried out on the basis of simple, static dispatching rules. This allows the generation of schedules in short computation times, but generally no optimal schedules based on the current state of the production system are generated. **Results of the 1st phase** In the first phase of the Brazilian-German cooperation project, a simulation-based optimisation method for controlling dynamic job shop production has been developed. The classical approach of simulation-based optimisation was extended in such a way that the dynamics of job shop manufacturing are taken into account and the optimisation of planning decisions and control rules is always based on the current system state. The developed method was evaluated considering the job shop production of a Brazilian producer of mechanical parts. **Objectives of the 2nd phase** In the second project phase, a method for the integrated control of inventory, production and maintenance processes has to be developed in order to map the current status of a production system in more detail. This means that maintenance orders can be scheduled for the machines in addition to the existing method and the inventory stocks can be taken into account for planning and control. **Approach** Initially, methods for planning maintenance jobs (Germany) and methods for inventory control (Brazil) using up-to-date system data will be developed in parallel. Subsequently, both approaches will be combined to an integrated inventory, production and maintenance control method, which will then be evaluated in a real scenario using data from the industry partner Rudolph Usinados as well as by scenarios from the literature.
