One of the central success factors for production in high-wage countries is the solution of the conflict that can be described with the term “planning efficiency”. Planning efficiency describes the relationship between the expenditure of planning and the profit generated by these expenditures. From the viewpoint of a successful business management, the challenge is to dynamically find the optimum between detailed planning and the immediate arrangement of the value stream. Planning-oriented approaches try to model the production system with as many of its characteristics and parameters as possible in order to avoid uncertainties and to allow rational decisions based on these models. The success of a planning-oriented approach depends on the transparency of business and production processes and on the quality of the applied models. Even though planning-oriented approaches are supported by a multitude of systems in industrial practice, an effective realisation is very intricate, so these models with their inherent structures tend to be matched to a current stationary condition of an enterprise. Every change within this enterprise, whether inherently structural or driven by altered input parameters, thus requires continuous updating and adjustment. This process is very cost-intensive and time-consuming; a direct transfer onto other enterprises or even other processes within the same enterprise is often impossible. This is also a result of the fact that planning usually occurs a priori and not in real-time. Therefore it is hard for completely planning-oriented systems to react to spontaneous deviations because the knowledge about those naturally only comes a posteriori.

Automation of robotic assembly processes on the basis of an architecture of human cognition

Marcel Ph. Mayer; Christopher M. Schlick; Daniel Ewert; Daniel Behnen; Sinem Kuz; Barbara Odenthal; Bernhard Kausch

A novel concept to cognitive automation of robotic assembly processes is introduced. An experimental assembly cell with two robots was designed to verify and validate the concept. The cell’s numerical control—termed a cognitive control unit (CCU)—is able to simulate human information processing at a rule-based level of cognitive control. To enable the CCU to work on a large range of assembly tasks expected of a human operator, the cognitive architecture SOAR is used. On the basis of a self-developed set of production rules within the knowledge base, the CCU can plan assembly processes autonomously and react to ad-hoc changes in assembly sequences effectively. Extensive simulation studies have shown that cognitive automation based on SOAR is especially suitable for random parts supply, which reduces planning effort in logistics. Conversely, a disproportional increase in processing time was observed for deterministic parts supply, especially for assemblies containing large numbers of identical parts.

Competence Profiling in Virtual Companies

Barbara Odenthal; Meikel Peters

The reorganization of the supply chain in the aerospace industry has led to a new situation for small and medium-sized enterprises (SME). In order to react to the changed requirements, one possible solution is the project-oriented and temporary cooperation of SME by building a Virtual Company. This again presents the employees with new challenges regarding the work requirements. Within the research project AerViCo - Aerospace Virtual Company - special tools and instruments considering the effects on employee performance behavior are being developed in order to increase labor productivity and to support the employees within the cooperation.

3D Assembly Group Analysis for Cognitive Automation

Christian Brecher; Thomas Breitbach; Simon Müller; Marcel Ph. Mayer; Barbara Odenthal; Christopher M. Schlick; Werner Herfs

A concept that allows the cognitive automation of robotic assembly processes is introduced. An assembly cell comprised of two robots was designed to verify the concept. For the purpose of validation a customer-defined part group consisting of Hubelino bricks is assembled. One of the key aspects for this process is the verification of the assembly group. Hence a software component was designed that utilizes the Microsoft Kinect to perceive both depth and color data in the assembly area. This information is used to determine the current state of the assembly group and is compared to a CAD model for validation purposes. In order to efficiently resolve erroneous situations, the results are interactively accessible to a human expert. The implications for an industrial application are demonstrated by transferring the developed concepts to an assembly scenario for switch-cabinet systems.

Cognitive Engineering for Direct Human-Robot Cooperation in Self-optimizing Assembly Cells

Marcel Ph. Mayer; Barbara Odenthal; Marco Faber; Jan Andries Neuhöfer; Wolfgang Kabuß; Bernhard Kausch; Christopher M. Schlick

In a work system with direct human robot cooperation the conformity of the operators expectation with the behavior of the robotic device is of great importance. In this contribution a novel approach for the numerical control of such a system based on human cognition and a cognitive engineered approach for the encoding of the systems a priori knowledge is introduced. The implementation using an established method in the field of design of cognitive systems is compared to a schema describing human decision making. Finally, simulation results of the implementation are compared to empirical tests with individuals.

Design and evaluation of an Augmented Vision System for human-robot cooperation in cognitively automated assembly cells

Barbara Odenthal; M. Ph. Mayer; W. Kabuss; Christopher M. Schlick

A research project has been initiated to study self-optimizing assembly cells and to design innovative ergonomic human-machine interfaces of the cells numerical control. An experimental assembly cell was designed where a robot carries out a certain repertoire of coordinated pick and place operations with small work pieces. In order to support the human operator while monitoring the operations and intervening in the case of assembly errors, an Augmented Vision System (AVS) has been designed and developed. The study described in this paper deals with the ergonomic presentation of assembly information by the AVS in order to support the human operator in developing a cooperative disassembly strategy between the human operator and robot. A laboratory experiment was carried out to compare two different participant groups (different professional education) and to investigate different decision support modes. A total of 44 participants participated in the experiments. The statistical analysis shows that the decision support mode as well as the different participant groups significantly influence the execution time of the participants (α=0.05).

Cognitively automated assembly processes: a simulation based evaluation of performance.

Marcel Ph. Mayer; Barbara Odenthal; Marco Faber; Christopher M. Schlick

The numerical control of an experimental assembly cell with two robots--termed a cognitive control unit (CCU)--is able to simulate human information processing at a rule-based level of cognitive control. To enable the CCU to work on a large range of assembly tasks expected of a human operator, the cognitive architecture SOAR is used. The CCU can plan assembly processes autonomously and react to ad-hoc changes in assembly sequences effectively. Extensive simulation studies have shown that cognitive automation based on SOAR is especially suitable for random parts supply, which reduces planning effort in logistics. Conversely, a disproportional increase in processing time was observed for deterministic parts supply, especially for assemblies containing large numbers of identical parts. In this contribution, the effect of phase-shifts in deterministic part supply is investigated for assemblies containing maximal different parts. It can be shown that the concept of cognitive automation is as well suitable for these planning problems.

Specification Model for the Development and Operation of a Virtual Company in the Aerospace Industry

Barbara Odenthal; Meikel Peters

The reorganization of the supply chain in the aerospace industry has led to a new situation for small and medium-sized enterprises (SME). The suppliers are forced to deliver completed systems instead of components and assemblies. In order to react to the changed requirements, one possible solution is the project-oriented and temporary cooperation of SME by building a Virtual Organization in order to stay competitive and marketable. The research project AerViCo - Aerospace Virtual Company - is aimed at developing standard business processes, structures and tools to support a Virtual Organization in the aerospace industry.

Design, Implementation and Evaluation of a Performance Measurement System for Virtual Enterprises in the Aerospace Industry

Meikel Peters; Barbara Odenthal; Christopher M. Schlick

Requirements towards suppliers in the aerospace industry are currently changing significantly. Aircraft manufacturers expect their suppliers not only to deliver components and modules but also to develop, manufacture and integrate complex systems independently. Furthermore, suppliers are expected to provide logistic support over the complete life cycle of their system, especially during their operation, e.g. with airlines. Thus, first-tier-suppliers must on the one hand offer the required competencies for the complex process of system integration, and on the other hand possess a sufficient financial capacity to carry the risks of product development. These requirements are met only by few companies, leading to a drastic reduction of potential first-tier suppliers. Companies that do not meet the mentioned requirements have to re-position within the supply-chain and become suppliers of subsystems or sub-subsystems for manufacturers of systems.
