Entwicklung eines Referenzmodells für eine echtzeitfähige zustandsorientierte Instandhaltung von komplexen technischen Systemen
Objective: Condition-oriented maintenance
Within the scope of the dissertation, a Condition Monitoring System (CMS) was developed which uses the Complex Event Processing (CEP) approach to achieve real-time monitoring of a system status, identify causes of faults and evaluate the status of technical components. This requires new information landscapes based on event-driven architectures. The work investigates on the one hand by means of a reference model how the CMS structure has to be designed for the successful application of the CEP approach and on the other hand the methodology for configuring the CMS so that sensor data of different components can be related to each other in real time for the correct assessment of global conditions.
A Flexible Integrated Forward / Reverse Logistics Model with Random Path
Ein methodisches Konzept zur Unterstützung der Kommerzialisierung von Elektrofahrzeugen in Richtung eines nachhaltigen städtischen Güterverkehrs
A Methodological Concept for Supporting the Commercialization of Electric Vehicles towards Sustainable Urban Freight Transport
eMobility in City Logistics
The use of electric commercial vehicles (ECVs) can support the achievement of sustainable urban freight transport (UFT). However, their commercial use in urban freight transport has so far remained relatively low. Combining the characteristics of ECVs and UFT preferences and evaluating them quantitatively could increase market penetration. Therefore, a Sustainable ECV-UFT Matching Concept was developed in the dissertation and implemented by an accordingly new simulation platform. Core of the concept are the methodology of assessment and the methodology of determination. The first evaluates the possible combinations quantitatively regarding the economic, social and ecological perspectives. The second helps decision makers to select the right combinations.

Kooperative Errichtung der Offshore-Windenergie - Konzeptionelle Entwicklung einer lieferketten- und projektübergreifenden Logistikgestaltung
Cooperative construction of offshore wind energy : Conceptional development of a supply chain and cross-project logistics design
SUUB Bremen, 2019
Wind energy: Cooperation & Collaboration
The thesis considers the topic of planning and control in the network of the construction phase of offshore wind energy. Due to the need for change and optimisation within the industry, a scientific discourse which goes beyond the existing framework is required. The result of this work includes the demonstration of efficiency improvement potentials as well as approaches for the implementation of resource and information sharing in the construction phase of offshore wind energy. For this purpose, approaches of cooperative logistics and a combination of supply chain-wide and cross-project collaborative logistics design were developed and the necessary success factors for implementation were elaborated.

Ein Lösungsverfahren für die integrierte Planung der Produktion in der Werkstattfertigung und den überbetrieblichen Transport
A solution procedure for the integrated planning of production in the job-shop manufacturing and the intercompany transport
Integration of production and transport
The developed integrated planning method for production and distribution scheduling is based on a framework with a multi-stage decomposition and integration procedure of the sub-problems. The integrated planning method applies this new multi-stage structure for the problem solving process and uses already known solution methods to solve the sub-problems. The evaluation shows that the overall costs of planning results generated by solution methods compared with are up to 26% higher than the overall costs of the planning results generated by the integrated solution method developed. Furthermore, it was proved in a sensitivity analysis that there is a positive impact on overall costs applying the integrated solution method developed within a wide range of cost parameters.
Standardisierung von Robotiksystemen in der Logistikfabrik der Zukunft - Konzeptentwicklung zur ontologischen Modularisierung und Konfiguration technischer Systemarchitekturen
The standardisation of robotic systems in the logistics factory of the future - developing a concept for the ontological modularisation and configuration of technical system architectures
Standard solutions provided by modular robots
This dissertation describes a concept for an overarching module and configuration management system, designed for industrial robotics systems in logistics processes. Due to their dynamic nature, these processes are difficult to manage from a technical point of view, meaning that numerous technical components are used. This results in cost-intensive isolated solutions rather than economically beneficial standard products. Based on the principles underpinning mass customisation, a system for modularising and configuring robot systems is being developed in a way that is specifically tailored to individual processes. The main approach for this is based on ontologies. This overarching concept enables modules to be developed and used in an integrative and comprehensive manner, thus reducing the number of isolated solutions.
Integrierte Planung von Produktions- und Transportprozessen mittels gemischt-ganzzahliger Optimierung
Integrated production and transport scheduling by mixed-integer programming
Optimal coordination of production and transport operations
In industry, nowadays, production planning and transport planning are done separately, while the related physical processes within a supply chain are closely linked with each other. This leads to the assumption that current planning methods do not generate the best possible schedules. This assumption is the topic of the dissertation, which investigates the differences in the results of a separate or an integrated planning of production and transport processes. The work also includes the development and evaluation of a new solution algorithm for the computation of integrated schedules.
Green Logistics Oriented Framework for the Integrated Scheduling of Production and Distribution Networks - A Case of the Batch Process Industry
eLib Staats- und Universitätsbibliothek, Bremen. 2017
Batches Green Logistics
Within the globalized environment, the flow of these batches is raising dramatically to satisfy the recurrent demands of the increasing population. This research develops a green logistics oriented framework in the case of the batch process industry in which we integrate the tactical and operational levels of planning and scheduling. The analysis results provide insightful results on supply chain costs and emissions. Based on the results, savings of about 43 percent of the total related economic and environmental costs are proved comparing to the actual situation at the tested cases. Building such a framework provides a practical tool which links being green and being economically successful.
Fertigungsregelung flexibler Fließfertigungen und Werkstattfertigungen zur Einhaltung von Lieferterminen - Integration von Auftragsfreigabe, Arbeitsverteilung, Reihenfolgebildung und Kapazitätssteuerung unter Nutzung des Potenzials Cyber-Physischer Produktionssysteme
Manufacturing control of flexible flow shops and job shops to keep due dates - Integrating order release, dispatching, scheduling and capacity control in cyber-physical production systems
GRIN Verlag, München. 2017
Integrated cyber-physical manufacturing control
The development towards cyber-physical production systems (CPPS) in the context of "IoT" causes a shift in the task structure of production planning and manufacturing control in favour of the latter. Besides order release, also the traditional planning tasks of dispatching, scheduling and capacity control are meanwhile tasks of manufacturing control. This thesis presents a method of manufacturing control, which considers the broadened task structure of manufacturing control in CPPS. The method is evaluated in flexible flow shop and job shop scenarios and benchmarked with traditional methods of manufacturing control.
Extension, Configuration and the Advantages of the Shifting Bottleneck Approach for Solving Dynamic Job Shop Scheduling Problems in Production and Logistics Processes
In: Informationstechnische Systeme und Organisation von Produktion und Logistik, Band 23. GITO Verlag, Berlin. 2016
Job Shop Production Scheduling
Production scheduling is a key part of intelligent production in the context of Industry 4.0. Furthermore, the demands of competition are forcing manufacturers to improve their adherence to deadlines when delivering customer orders. This thesis expands on the Shifting Bottleneck (SB) method by adding the Variable Neighbourhood Search (VNS) in order to solve the job shop scheduling problem which is used extensively to model make-to-order manufacturing processes. It also provides guidelines for configuring the method. After carrying out computational experiments on benchmark instances with up to 150 orders and 20 machines, and conducting comparisons with state-of-the-art approaches, the results indicate that the SB method that has been developed is currently the most promising approach for practical applications.
Entwicklung eines Integrationsmodells zur Zustandserfassung und Optimierung der Instandhaltung komplexer technischer Systeme
Development of an Integration Model for Status Detection and Optimisation of Maintenance for Complex Technical Systems
Modern Maintenance Systems in the Spotlight
From an operational perspective, maintaining complex technical systems is a huge challenge. Status-based maintenance improves the planning and management of maintenance activities, and the use of technical equipment for status detection purposes in particular is increasingly gaining in importance. This paper investigates the extent to which the development of an integration model for status detection and optimisation of maintenance for complex technical systems is required. The result is the development of a comprehensive procedure for the successful integration of status-based maintenance methods in complex operational environments, which is tested in a case study using port handling equipment as an example.
Konzeption und Entwicklung einer Planung und Steuerung von Ladungsträgern in der Logistik
Design and development of planning and control of load carriers in logistics
Transparency in transport logistics
The demand for what are known as intelligent, innovative and efficient transport systems is constantly on the increase in the logistics sector. To meet this demand, concepts are needed that can sustainably cut down on freight traffic. This project aims to design and develop a system that supports the planning and control of load carriers in logistics in order to meet the aforementioned demand. In order to do this, the basic principles of all the areas relevant to this topic are discussed in detail. By integrating and implementing examples, the defined objectives can be checked in terms of their performance in order to verify the effectiveness of the system. A final discussion aims to show the need for further research on this subject.
Kapazitätssteuerung auf Basis rekonfigurierbarer Werkzeugmaschinen - Potenziale und Grenzen am Beispiel der Werkstattfertigung
Capacity control based on reconfigurable machine tools – potentials and limitations using the example of a job shop production
In: Scholz-Reiter, B. (eds.): Informationstechnische Systeme und Organisation von Produktion und Logistik, Band 22. GITO Verlag, Berlin. 2016
Increased flexibility in production
Capacity control in manufacturing is tasked with fulfilling a high achievement of the logistic objectives. This requires a certain degree of flexibility in terms of capacity which is typically achieved through the flexible deployment of the available employees and adaptations to working hours. In addition to this, the development of reconfigurable machine tools can increase capacity flexibility in the future. Against this background this thesis discusses the potentials and limitations of such machines when it comes to controlling capacity in a job shop production. Thus, the thesis emphasizes the positive impact of reconfigurable machine tools on economically relevant objectives such as inventory, lead time, adherence to delivery dates and utilization.
Selbststeuernde Disposition im Umlaufmanagement von Verleihartikeln
Autonomously controlled disposition
Global markets for customer oriented individual products challenge companies due to the resulting complex and dynamic production and logistic networks. Innovative production control methods constitute a possibility to manage the correspondingly complex processes, both within individual companies and global networks. This doctoral thesis evaluates the application of the autonomous control paradigm in the sector of event logistics, especially in relation to the disposition of rental articles. At this, methods for route planning and order disposition from this field are adapted to the practical example. The result is an autonomously controlled disposition system for event logistics.
3D Objekterkennung von ungeordneten Stückgütern für die automatische Entladung von Containern
3D object recognition of unsorted goods for the automatic unloading of containers
In: Scholz-Reiter, B. (eds.): Informationstechnische Systeme und Organisation von Produktion und Logistik, Band 21. GITO Verlag, Berlin. 2016
Intelligent and robust object detection
Rapid progress in the field of 3D sensor technology and artificial intelligence has made it possible to develop cognitive and flexible robotic systems that do not require predefined and constant environmental conditions, therefore enabling robots to react to unforeseen events. Developing a flexible robot for unloading different types of goods from containers requires an object recognition method that is able to detect and locate individual goods from several classes of forms and unknown sizes correctly. The method analyses 3D sensor data from a laser scanner. As part of this thesis, an object recognition method was developed and evaluated using realistic test scenarios in a demonstrator and simulated sensor data.
Verfahren zur Merkmalsbeschreibung von Oberflächendefekten für den Einsatz von maschinellem Lernen in der optischen Inspektion metallischer Mikrobauteile
Method of Describing Features of Surface Defects in Order to Use Machine Learning in the Optical Inspection of Metallic Micro-Components
Deep Learning in Optical Inspections
The main objective of the investigation is reliable defect detection from sensorial data. This thesis focuses on two strategies. The first strategy is based on existing state-of-the-art feature representations and classification methods. Specifically, multi-scale texture analysis in combination with statistical feature representation is used to describe defective areas. In traditional machine learning, features are hand-coded and therefore designed manually. In contrast, the second strategy implements Deep Learning, which introduces feature generation into the learning process. The focus of this investigation is different design choices and hyperparameters and their influence on the overall detection result.
Ein Vorgehensmodell zur Entwicklung computerbasierter Planspiele für kleine und mittlere Unternehmen (KMU) in Kooperationsnetzwerken
A process model for developing computer-based simulation games for small and medium-sized enterprises (SMEs) in collaborative networks
Process model for developing simulation games
In SMEs, the success of company cooperation is determined by its employees' ability to cooperate. Employees who previously had no direct connection with collaborative processes are faced with new tasks that they are not always able to overcome. Simulation games have been proven to be a successful method of imparting the skills necessary for this. This thesis develops a process model that identifies key design elements for a company-specific simulation game template by analysing the current business situation. Employees can use the simulation game developed to train their skills using authentic cooperation scenarios.
Produktionsplanung und -steuerung in mehrstufigen Batchproduktionen - Methoden der Loskomposition und -terminierung bei stufenspezifischen Auftragsfamilien
Production planning and control in multi-stage batch productions – Methods for batch composition and scheduling in stage-specific order families
Short lead times for large batches
The dilemma of operations scheduling is a familiar challenge when it comes to planning in the manufacturing industry and describes the trade-off between minimum lead times and maximum capacity utilisation. This research illustrates that the influence that these two factors have on each other is in no way linear. It develops planning and control methods for multi-stage, simultaneous batch productions with stage-specific order families. Adapting them to an application scenario from the automotive industry dramatically reduces downtimes while keeping batch sizes economical at the same time. This result shows that competing targets do not follow a general trade-off function and that specific planning approaches can generate solutions that make sense in both regards.
Manufacturing industry supply chain modeling and improvement in developing countries
Enhance Companies Performance through Entire Supply Chain Integration
Manufacturing industries are in dynamic changes in both developed and developing countries. The literature suggested that supply chains (SC) compete, not companies. The performance of firms in DC is expected to contribute to the improvement of the entire SC. It is critical to seek a process-oriented model that facilitates modeling efforts. The most promising is the SC operations reference model. However, this model is tailored to the needs of developed industries. Particularly, the early processes situated in the DC have different situations and are not considered in the model. This thesis investigates the characteristics of SC that support model adaptation. The main contribution of this thesis is an adapted business process with its building blocks.
Berücksichtigung des inneren Werkstückzustands bei der Arbeitsplanung am Beispiel des Bauteilverzugs von hochfesten Stahlbauteilen der Antriebstechnik
Consideration of the internal workpiece condition during work planning using the example of component distortion in high-tensile steel - components of propulsion technology
In: Thoben, K.-D.; Müller, D. H. (eds.): Bremer Schriften zur integrierten Produkt- und Prozessentwicklung. Verlagsgruppe Mainz GmbH, zgl. Elektronische Bibliothek (E-LIB) der Universität Bremen, 2015
Two planning aids to counteract errors
Repeating work costs money, and the later an error has to be rectified, the more expensive it becomes. Expenses are more likely to be incurred if an error is allowed to propagate. Planning for the future can therefore save a lot of money. The aim of this paper was to support work planning and, in particular, work plan creation in such a way that the internal workpiece condition can be described when planning high-tensile steel components of propulsion technology with regards to distortion. It should be possible to use this to anticipate and consider undesired changes in terms of dimensions and shape during the planning phase. Two planning tools (recommendations for planning and process chain comparison) have been proposed as a solution during research activities.
Entwicklung einer systematischen Vorgehensweise für bionischen Leichtbau
Lightweight design principles from nature
In the science of engineering there is knowledge about a well-established procedure for constructing lightweight designs. A critical step within this procedure is the search for a suitable concept. In the technical field, this critical step is usually solved through practical experience and by using existing constructions serving as models. In nature the evolution has created mature constructional principles which can serve as models for technical lightweight constructions. A corresponding expansion of the established approach to the knowledge of nature leads to a variety of innovative lightweight designs, expanding the potential for highly effective constructions.
Modelling of supply chain processes in the mineral raw materials industry from the perspective of EM, SCOR and DCOR models
Process Modell in the mining industry
At present, existing solutions for supply chain models focus primarily on the manufacturing industry, rather than on the entire supply chain, as they do not incorporate the processes of the mining industry. In a comparison of processes of the mining industry with those of the manufacturing industry, the sourcing process was revealed as the area with the greatest disparity. The sourcing process in mining differs from the “source” process of the SCOR model. With respect to mining, modelling efforts focus on the processes of exploration, engineering design, construction and extraction. To develop the modelling techniques of these processes, each process was analysed in order to adapt SCOR and DCOR models to these processes by using mining language to guide the implementation of the developed model.
Electronic Seals and their Influence on the Dynamics of Container Logistics
Technology for container security
Electronic seals (E-Seals) are a technology that promises to improve security and safety during container transportation processes. However, not much research has been devoted to exploring systematically this technology's influence on the dynamics of container flows. This research aims to investigate the possible impacts of different types of E-Seal on container logistics and, in particular, on its dynamics. Several theoretical models have been developed to solve this task. The simulation outcome has been applied in cost-benefit-analyses for eight different business cases to approve the adoption of different types of E-Seal in container systems. In addition, the most feasible advantages of E-Seals and a framework for their applications have also been determined.
Konzeption und Bewertung dynamischer Logistikprozesse für Netzwerke der Offshore-Windenergie
Conception and Evaluation of Dynamic Logistics Processes for Offshore Wind Energy Networks
In: Scholz-Reiter, B. (eds.): Informationstechnische Systeme und Organisation von Produktion und Logistik, Band 19. GITO Verlag, Berlin. 2015
Standards for Greater Transparency
Very few production, transport and installation strategies can be transferred from onshore to offshore wind turbines due to the harsher conditions in offshore applications (weather, transportation by ship, etc.). The production and logistics networks – which vary from project to project – have to cope with significant logistical challenges and extremely dynamic circumstances. Standard IT systems are not able to meet requirements relating to planning, management, event simulation and statuses. As the basis for an IT system, this paper develops an information flow concept designed to increase transparency for offshore wind energy logistics networks, derives relevant installation and logistics concepts, tests them as prototypes and then incorporates them into standard processes.
Durchlaufzeitharmonisierende Kapazitätssteuerung in der Werkstattfertigung - Erweiterung der kurzfristigen Kapazitätsflexibilität durch den Einsatz rekonfigurierbarer Werkzeugmaschinen
Throughput time harmonising capacity control in job-shop systems – Extended short-term capacity flexibility based on an application of reconfigurable machine tools
In: Scholz-Reiter, B. (eds.): Informationstechnische Systeme und Organisation von Produktion und Logistik, Band 20. GITO Verlag, Berlin. 2015
Harmonised throughput times in production
The ability to plan the estimated throughput time of individual orders precisely in advance is of key importance for manufacturing companies, as it allows them to accurately predict the earliest possible delivery date. In this context, shorter delivery times represent a significant competitive advantage compared to other companies. Due to complex material flow structures, external fluctuations in demand cause huge variations in throughput times as well as a high proportion of waiting times, particularly in job-shop systems. The presented concept of throughput time harmonising capacity control extends the state of the art. This capacity control aims to improve the predictability of throughput time by considering the potential of reconfigurable machine tools.
Delivery time uncertainty in dynamic supply networks
Improved Control, more Reliability
Complex networks of suppliers, manufacturers and distributors are characterized by uncertainty. In order to handle this hardly predictable factor, managers must be able to know, and, if possible, monitor and control, its causes, influences and effects. This is the starting point for this thesis. It addresses the main types of uncertainties in complex supply networks. Critical routes were defined in PERT networks, and the uncertainty of the compliance with a specific delivery date was calculated by means of a combination of stochastic and mathematical models. This solution provides a more reliable control tool, leads to more reliability and makes an increase in performance in dynamic networks possible.
Dynamische Selektion von Regeln zur Reihenfolgeplanung in der Werkstatt- und flexiblen Fließfertigung
Dynamic selection of priority rules for job shop and flexible flow shop scheduling
Significantly Better Prediction Results
Scheduling presents a highly complex problem which is of great relevance to industrial enterprises. In dynamic job shop and flexible flow shop scheduling, priority rules are often appliedto this end. As there is no rule which satisfactorily fulfils the target criterion in every situation, a dynamic method of selection and/or adaptation has been developed in the scope of a doctoral thesis. Predictions were made by applying Gaussian process regression models, based on which the adequate rules were dynamically selected. Evaluations in job shop and flexible flow shop scheduling revealed that significantly better predictions can be obtained this way and that the newly developed control method accounts for an enhanced performance.
Modellierungskonzept zur integrierten Planung und Simulation von Produktionsszenarien entwickelt am Beispiel der CFK-Serienfertigung
Integrating Eight Modeling Levels
The industrialization of CFRP production demands new engineering tools in order to develop more efficient production systems. This thesis presents a new concept for digital production system engineering in the context of Digital Factory, which is focused on the integrated planning and simulation of complex CFRP production scenarios. As an approach to model-driven engineering, a domain-specific modeling language and a factory data model were developed to generate material flow simulation models. Thereby, major challenges of CFRP production engineering were considered and an eight-level modeling concept called GRA MOSA was developed which allow the management of alternative production scenarios by supporting manufacturing as well as logistics planning.
Entwicklung und prototypische Implementierung einer Methode zur Modellierung mobiler Interaktionsgeräte für intelligente Produktionsumgebungen
Technical Design Recommendations
This thesis is concerned with the conception of a design method for modeling mobile interaction devices with a special focus upon intelligent production environments. Its main result represents a method which identifies and describes the necessary model-based tasks for designing mobile interaction devices (mobile input devices, output devices and communication devices). An essential part of the method consists of a modeling tool based on a context model for configuring work situations in intelligent production environments. This tool enables the generation of technical design recommendations to be followed by product developers creating mobile interaction devices in the early phases of product development.
Messung und Bewertung selbststeuernder Produktionssysteme
A Three-Component Evaluation System
The implementation of autonomous logistic processes in production systems is capable of improving logistic target achievement in connection with increasing complexity. To this end, a three-component evaluation system for autonomous production systems was developed in this study. The main task of the system is to measure the logistic target achievement in the conflicting field of autonomous control and complexity levels. The system is capable of displaying these relationships. Its validation proceeded with simulation models and real data derived from a shop floor manufacturer. Simulations were conducted with varying levels of autonomous control and complexity to study the system’s application potential.
Simulationsgestützte Entwicklung von Synchronisationsstrategien für Prozesse produktionslogistischer Systeme am Beispiel der Werkstattfertigung
In: Scholz-Reiter, B. (eds.): Informationstechnische Systeme und Organisation von Produktion und Logistik, Band 17. GITO Verlag, Berlin. 2013
Improvement of Logistic Parameters
A heterogeneous product range, varying numbers of pieces, and the highly interconnected structures of material flow make it difficult to coordinate all logistic processes in shop manufacturing. One solution consists in the synchronization of logistical processes. Synchronization theory offers applicable methods for this purpose. In order to benefit from this form of decentralized self-organization, physical theory was combined with logistic processes, making it possible to represent both status and progress of a process by applying the concept of phase display. Phase coupling led to strategies which were evaluated by means of a simulation study. This thesis shows that the logistic target parameters can be improved this way.
Mono-Material-Strukturen in der automobilen Anwendung zur Erhöhung der Recycelfähigkeit
In: Thoben, K.-D.; Müller, D. H. (eds.): Bremer Schriften zur integrierten Produkt- und Prozessentwicklung, Band 77. Verlagsgruppe Mainz GmbH, Aachen. 2013
Particularly suited for PET
High-quality recycling of plastics requires very specific separation methods. To exploit the intrinsic material properties, various plastics were combined and built into a component. Currently available recycling processes are not able to identify and separate this mixture of plastics. However, the application of a new single-material approach revealed that components consisting of only one plastic species display identical properties, thus reducing the challenge of sortingconsiderably. In addition, the degradation behavior of plastics is an essential aspect. The effects of the “quality of substitution “ and the “proportion of substitution” on various material properties and it is revealed that PET is particularly suited for this approach.
Knowledge-based Product and Service Composition for IP Multimedia Subsystems
In: Thoben, K.-D.; Müller, D. H. (eds.): Bremer Schriften zur integrierten Produkt- und Prozessentwicklung, Band 76. Verlagsgruppe Mainz GmbH, Aachen. 2013
For New Telecommunication Services
The telecommunications industry is undergoing rapid changes. However, the great complexity of the telecommunication networks (TC networks) hampers the development of new innovative TC services. The concept presented in this thesis makes it possible to provide TC services oriented to individual customer requirements, lower development and maintenance costs, and shorten product cycles. It applies the principle of modular design and approaches to knowledge modeling which have been adjusted and further developed to TC specifications. The standard architecture of future TC networks, i.e. the IP Multimedia Subsystem Architecture, serves as a platform. The concept was tested under real-life conditions and is now already being used to develop commercial TC services.

Entwicklung selbstoptimierender Prozesse in der NC-Verfahrenskette
Great Potential for Efficiency Enhancement
Competition in the automobile industry forces the tool and die shops into a continual optimization process. In their machining departments, both automated NC programming and continual optimization processes for cutting strategies promise a great potential for efficiency enhancement. It is shown that the two approaches have hitherto actually contradicted each other. The automation of NC-programming is founded upon comprehensive standardization of the manufacturing processes and thus prevents the optimization of manufacturing strategies through modifications made by the users. The self-optimizing processes explored in this dissertation combine the potentials for single piece production with similarities in the machining process.
Simulationsbasierte Analyse der Dynamik in Produktions- und Logistiknetzwerken unter Verwendung von Methoden der Nichtlinearen Dynamik
In: Scholz-Reiter, B. (eds.): Informationstechnische Systeme und Organisation von Produktion und Logistik, Band 16. GITO Verlag, Berlin. 2013
Creating more Efficient Production Systems
The specialization of companies has led to a stronger urge to synchronize processes in networks. Here, however, effects also occur which cannot be adequately addressed by applying common planning and control methods. One example is deterministic chaos, which may cause an only apparently random behavior. The use of methods of nonlinear dynamics is a promising approach to describe such phenomena as well as identify nonlinear dependencies and dynamic working relationships. The aim is to identify policies and strategies that will ensure an efficient operation of the production system, evenif there are high degrees of complexity and dynamic boundary conditions.

The realisation of efficient product ramp-ups represents an essential competitive factor for small and medium-sized enterprises. By methodical control of interference factors, companies are able to realise ramp-up goals in regard to time, cost, quality and quantity. Efficient utilisation of ramp-up supporting programs, classifications, methods and tools is a precondition to meet these goals. Therefore, structured knowledge has to be available in a coordinated way. Mr. Krohne developed in his thesis an evaluation method, which supports the structured identification of ramp-up specific knowledge in order to improve it. The method has been realised in a software demonstrator and was exemplarily used in an automotive supplier company.
