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
A General Methodology for Adapting Industrial HMIs to Human Operators
Full text linkModern 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
An Adaptive Virtual Training System Based on Universal Design
Full text linkThe increasing complexity of manufacturing environments requires effective training systems to prepare the operation personnel for their tasks. Several training systems have been proposed. A common approach is the application of virtual environments to train interactions with an industrial machine in a safe, attractive, and efficient way. However, these training systems cannot adapt to the requirements of an increasingly diversified workforce. This paper introduces an approach for the design of an adaptive virtual training system based on the idea of universal design. The system is based on a two-step approach that consists of an initial adaptation to the user capabilities and real-time adaptations during training based on measurements of the user. The adaptations concern the use of different representations of lessons with different complexity and interaction modalities. The proposed approach provides a flexible training system that can adapt to the needs of a broad group of users
Rahmenwerk zur modellbasierten horizontalen und vertikalen Integration von Standards für Industrie 4.0
No full textIn Anlehnung an die Umsetzungsempfehlung des deutschen Arbeitskreises zu Industrie 4.0 widmen wir uns in diesem Kapitel dem offenen Handlungsfeld der Standardisierung und Referenzarchitektur im Kontext einer modellbasierten horizontalen und vertikalen Integration. Wir zeigen, dass die Zusammenführung international etablierter Standards genutzt werden kann, um eine flexible Informationsarchitektur zu schaffen. Zu diesem Zweck präsentieren wir ein offenes, dreidimensionales Rahmenwerk von Standards für Industrie 4.0. Die erste Dimension berücksichtigt die Unterscheidung zwischen den unterschiedlichen Ebenen in einem Unternehmen, in Anlehnung an die klassische Automatisierungspyramide. Die zweite Dimension unterscheidet zwischen den internen und den externen Aspekten der horizontalen und vertikalen Integration. Die dritte Dimension differenziert zwischen der wirtschaftlichen Tätigkeit der teilneh-

No full textMobile Charging as a Service: A Reservation-Based Approach
Full text linkThis paper aims to design an intelligent mobile
charging control mechanism for Electric Vehicles (EVs), by
promoting charging reservations (including service start time,
expected charging time, and charging location, etc.). EV mobile
charging could be implemented as an alternative recharging solution, wherein charge replenishment is provided by economically
mobile plug-in chargers, capable of providing on-site charging
services. With intelligent charging management, readily available
mobile chargers are predictable and could be efficiently scheduled
towards EVs with charging demand, based on updated context
collected from across the charging network. The context can
include critical information relating to charging sessions as well
as charging demand, etc. Further with reservations introduced,
accurate estimations on charging demand for a future moment
are achievable, and correspondingly, optimal mobile chargersselection can be obtained. Therefore, charging demands across
the network can be efficiently and effectively satisfied, with the
support of intelligent system-level decisions. In order to evaluate
critical performance attributes, we further carry out extensive
simulation experiments with practical concerns to verify our
insights observed from the theoretical analysis. Results show
great performance gains by promoting the reservation-based
mobile charger-selection, especially for mobile chargers equipped
with suffice power capacity
