Lossless data exchange is one of the recent investigated paths for engineering process improvement with respect to engineering process quality and efficiency. AutomationML is one data exchange format in a broad range of modern XML based data formats developed for the improvement of engineering processes of manufacturing systems. In this paper the applicability of AutomationML is proven for transferring...
Modeling complex mechatronic systems containing parts such as mechanics, electronics and software is a major challenge for the engineering of automation production systems. As a result, many modeling languages as well as tools (e.g. petri nets or MATLAB/Simulink) and verification approaches (e.g. testing, simulation or formal verification) that focus on special challenges to model the mechatronic...
In recent days, with the advancement of cloud computing the usage of Web services has increased rapidly. Therefore, discovery of services has become one of the challenging activities nowadays for the service consumers. In this paper we propose a dynamic service discovery methodology based on term vector space model. The proposed mechanism supports the identification of service during its run time...
The paper addresses the problem of coverage testing of industrial automation software represented in the IEC 61499 standard, one of the recent standards for distributed control system design. Contrary to model-based testing (MBT), the paper focuses on implementation coverage, not model coverage. An approach based on evolutionary algorithms is presented which generates coverage test suites for both...
Industrial control systems are an important part of critical infrastructures and their uninterrupted operation is important for many aspects of society. In recent years these systems have come under more scrutiny, as reports about attacks on them have become more frequent. There is therefore a need to better secure them, and the first step to achieve this is to identify the threat landscape for such...
Automated production systems involve multiple engineering disciplines and often operate for several decades. Therefore, in order to leverage benefits of model-based system engineering, modeling approaches must handle both multiple disciplines and variability. As a first step towards variability modeling and management, a small case study is carried out to investigate the opportunities and challenges...
The continuous changes on the market and customer demands have forced modern automation systems to provide more strict Quality of Service (QoS) requirements such as load balance or full availability of the control system, among other characteristics. In order to cope with these demanding requirements, modern automation systems have started to incorporate novel design approaches which include reconfiguration...
The development of Systems-of-Systems (SoS) architectures is challenged by the inherent characteristics of SoS such as operational independence, heterogeneity of constituent systems, emergent behavior and large-scale distribution. At present, the resulting complexity restricts the design space exploration of SoS architectures to be focused on cost and functionality. In this paper we extend our previous...
During the last years the increasing installation of distributed energy resources, electric vehicles bus also energy storage systems has lead to new challenges in terms of power system planning and operation. New intelligent approaches turning power distribution grids into Smart Grids are necessary. For their realization standardized automation, control and communication systems are essential. Moreover,...
Automated machines and plants are operated for some decades and undergo an everlasting evolution during this time. In this paper, we present three related open evolution challenges focusing on software evolution in the domain of automated production systems, i.e. evolution and co-evolution of (interdisciplinary) engineering models and code, quality assurance as well as variant and version management...
Machine and plant automation (M&PA) is becoming more and more complex, especially, as additional functionality is realized by a rising amount of software. In order to meet high requirements regarding the quality of these machines and plants, sophisticated methods for quality assurance (QA) are needed. Interaction diagrams have been established throughout different domains for specifying use cases,...
For manufacturing industry seamless workflows along the whole product lifecycle are crucial for sustainable success. Although the integration of all used systems to a single supersystem is not reasonable, the integration of data is essential. This contribution introduces a model-based concept to integrate data elements of distributed data systems and sources to one virtual database. Specific view...
