“…The second approach uses human performance consequences such as the mental workload and the skill degradation (Parasuraman, Sheridan, and Wickens 2000) in addition to automation reliability and the costs of decision and action outcomes. A third approach is the decision graph based on seven questions about the planned production, the product and the assembly operations (Konold and Reger 2003). The answers to these questions lead to four decision options: manual, automatic or one of two hybrid systems.…”

International audienceThe aim of this paper is the study of methods for assembly representation supporting the level of automation (LoA) decision .process. Based on a literature review on the topic of LoA deciding, a need for involving the assembly sequence in the decision was identified. The representation methods used in both assembly modeling and planning and other more generic approaches in the literature were studied and evaluated. The evaluation has been based on a requirements definition describing how the representation should support the decision about automation. Identified gaps in requirement satisfaction from the existing approaches led to the definition of the Assembly Sequence Modeling Language (ASML), a new modeling language that combines principles from and improvements on the studied methods and a standard vocabulary of assembly actions. The modeling language was demonstrated in an assembly example and was successfully evaluated with regard to the defined requirements. Thus, this new modeling approach, ASML, is offered as an innovative and intuitive support in the decision making process for selecting automation levels in Assembly

“…To determine the maximum/ minimum deviation of the tolerance chain, the chain's links with their maximum/ minimum tolerances are added. [8] maximum of the tolarance chain minimum of the tolarance chain maximum tolarance of the component i minimum tolarance of the component i number of components within the assembly When a mounting capability is given by this maximum/minimum method, a complete replacement of the individual components is possible and the assembly will always be successful [7]. Assuming, however, that the existence of individual tolerances is random, and that they do not represent a specific trend or a systematic error within the assembly process, a worst-case scenario would lead to unnecessary costs and complexity.…”

Abstract. Today's industrial assembly systems have to enable individualized production as well as to feature a high degree of automation to cope with both quality requirements and increasing cost pressure. An overall tolerance concept is necessary to allow processes under the above referenced conditions. Reducing costs and the complexity of assembly processes can be achieved by an assembly product design based on the information provided by a tolerance analysis. This paper describes industrial standards and innovative concepts of a holistic tolerance management that are independent of product size.

Since flexible production systems usually require special technologies and additional components, high costs are the main limitation factor for their flexibility. Therefore, the most economic components have to be chosen for each flexible production system. This paper focuses on automatic feeding systems and starts with a comparison of the flexibility and the feeding rates of the most important flexible feeders available today. To cope with the deficits of flexible feeders with mechanical orientation, a new modular system is presented. In addition, a design method for the different modules of the new feeder is introduced. Finally, a detailed cost analysis determines the economic application of the modular feeder within the presented systems in dependency of the given flexible feeding task.
