No full textA SysML Based Design Pattern for the High-Level Development of Mechatronic Systems to Enhance Re-Usability
No full textModel driven engineering approaches can be used to handle the complexity in the development of modern mechatronic systems, containing a multitude of mechanical, electrical/electronic and software components. However, up to now SysML, as standard systems engineering language, is not wide spread in industry yet. Reasons therefore are missing adequate guidelines for the modeling process as well as an unclear benefit of the created SysML-models. A well-created system model however poses enormous time advantages during the analysis of change influences in later lifecycle phases of the system and makes an interdisciplinary reuse of modules in the development of new systems possible. A prerequisite therefore is the efficient traceability of all information within the system model. Thus, in this paper a SysML based process for the high-level development of mechatronic systems is applied, reaching from requirements specification to the detailed modeling of the element-connections (discipline specific as well as interdisciplinary). Our approach shows how the information from the different levels of abstraction and the different development phases can be connected, including a functional modularization of the mechatronic system. In this way, developers can trace change influences more easily. The functional modules can be used during the development of new systems, resulting in significant shortened development cycles. The proposed design pattern is shown at the example of a bench-scale model of a production plant
Irgendwo zwischen Industrie 3.5 und 4.x
No full textIndustrie 4.0-Systeme werden bereits von einigen Anbietern von Automatisierungstechnik aber auch von Komponentenlieferanten angeboten und verkauft, Demonstratoren spriessen wie Pilze aus dem Boden und andererseits wird das Begriffsgebäude noch definiert ebenso wie die dazu gehörenden Architekturen. Sind wir also schon auf dem Weg zu Industrie 4.x oder erst bei 3.7? Benötigen wir einen neuen Begriff, eine neue Herausforderung um voran zu kommen? Wie wird Industrie 4.0 international gesehen und erforscht? Das Heft zum Thema Industrie 4.0 versucht eine Übersicht über die verschiedenen Sichten zu geben: die Industriesicht der Automatisierungstechnik und der Informationstechnik und die Sicht der verschiedenen Anwendungsbereiche von Logistik (ten Hompel) über Automatisierungstechnik (Jasperneite, Papenfort, Vogel-Heuser) bis hin zur Informatik (Eckert, Wehle). Internationale Delegationen reisen durch Deutschland, um das Phänomen Industrie 4.0 zu ergründen, denn es ist mehr als nur ein technischer Ansatz. Vor circa 1,5 Jahren sind Organisationen, Forscher und Industrieunternehmen unter dem Stichwort Industrie 4.0 hochmotiviert aufgebrochen, um die Vision einer vertikalen und horizontalen Integration für die intelligente, vernetzte Produktion und Logistik umzusetzen. Das Heft zeigt verschiedene Sichten dieser Entwicklung
A General Methodology for Adapting Industrial HMIs to Human Operators
No full textModern production systems are becoming more and more complex to comply with diversified market needs, flexible production, and competitiveness. Despite technological progress, the presence of human operators is still fundamental in production plants, since they have the important role of supervising and monitoring processes, by interacting with such complex machines. The complexity of machines implies an increased complexity of human-machine interfaces (HMIs), which are the main point of contact between the operator and the machine. Thus, HMIs cannot be considered anymore an accessory to the machine and their improvement has become an important part of the design of the whole machines, to enable a nonstressful interaction and make them easy to also use less skilled operators. In this article, we present a general framework for the design of HMIs that adapt to the skills and capabilities of the operator, with the ultimate aim of enabling a smooth and efficient interaction and improving user's situation awareness. Adaptation is achieved by considering three different levels: Perception (i.e., how information is presented), cognition (i.e., what information is presented), and interaction (i.e., how interaction is enabled). For each level, general guidelines for adaptation are provided, thus defining a meta-HMI independent of the application. Finally, some examples of how the proposed adaptation patterns can be applied to the case of procedural and extraordinary maintenance tasks are presented. Note to Practitioners-This article was motivated by the problem of facilitating the interaction of human operators with human-machine interfaces (HMIs) of complex industrial systems. Standard industrial HMIs are static and do not consider the user's characteristics. As a consequence, least-skilled operators are prevented from their use and/or have poor performance. In this article, we suggest a novel methodology to the design of adaptive industrial HMIs that adapt to the skills and capabilities of operators and compensate their limitations (e.g., due to age or inexperience). In particular, we propose a methodological framework that consists of general rules to accommodate the user's characteristics. Adaptation is achieved at three different levels: Perception (i.e., how information is presented), cognition (i.e., what information is presented), and interaction (i.e., how interaction is enabled). The presented rules are independent of the target application. Nevertheless, we establish a relationship between such design rules and user's impairments and capabilities and kind of working tasks. Hence, designers of HMIs are called to instantiate them considering the specific requirements and characteristics of the users and the working tasks of the application at hand

No full textMethodological Approach for the Evaluation of an Adaptive and Assistive Human-Machine System
No full textWith the increasing complexity of modern industrial automatic and robotic systems, an increasing burden is put on the operators, who are requested to supervise and interact with such complex systems, typically under challenging and stressful conditions. To overcome this issue, it is necessary to adopt a responsible approach based on the anthropocentric design methodology, such that machines adapt to the humans capabilities. Moving along these lines, a methodological approach called MATE was introduced in [1], which consists in devising complex automatic or robotic solutions that measure current operator's status, adapting the interaction accordingly, and providing her/him with proper training to improve the interaction and learn lacking skills and expertise. In this paper we propose an evaluation and validation procedure to guarantee the achievement of the requirements of a MATE system
An Adaptive Speech Interface for Assistance in Maintenance and Changeover Procedure
No full textMachine operators remain important in future production environments and need intuitive and powerful interaction techniques. Many assistance and support applications for machine operators use speech-based interfaces since they are suitable during manual tasks and when visual attention cannot be occupied. Due to developments like the demographic change or the need for skilled personnel, the skills and capabilities of the workers will become increasingly diverse. Speech-based interfaces therefore need to be adaptable to the capabilities, limitations and preferences of individual operators. This paper addresses this requirement and proposes an adaptive speech interface that supports machine operators during maintenance and changeover procedures. All aspects of the proposed application can be adapted to the requirements of the user. The system uses a process model, instruction templates, a user model, and a model of the input vocabulary to describe the components of the application. This allows a flexible adaptation of the speech interface and the provided instructions to the requirements of individual users and to further use cases
Towards modern inclusive factories: A methodology for the development of smart adaptive human-machine interfaces
No full textModern manufacturing systems typically require high degrees of flexibility, in terms of ability to customize the production lines to the constantly changing market requests. For this purpose, manufacturing systems are required to be able to cope with changes in the types of products, and in the size of the production batches. As a consequence, the human-machine interfaces (HMIs) are typically very complex, and include a wide range of possible operational modes and commands. This generally implies an unsustainable cognitive workload for the human operators, in addition to a non-negligible training effort. To overcome this issue, in this paper we present a methodology for the design of adaptive human-centred HMIs for industrial machines and robots. The proposed approach relies on three pillars: measurement of user's capabilities, adaptation of the information presented in the HMI, and training of the user. The results expected from the application of the proposed methodology are investigated in terms of increased customization and productivity of manufacturing processes, and wider acceptance of automation technologies. The proposed approach has been devised in the framework of the European project INCLUSIVE
