In the design of plants and machines the complexity is permanently increasing. Model-driven design methodologies in the field of Industrial Automation and Control Systems, as proposed by the MEDEIA project, help to cope with current requirements like limited budget and reduced ramp-up time. Concurrent development in all involved domains is facilitated by the introduction of simulation in the development...
In a complex manufacturing environment the ability to handle unexpected events is from crucial importance. Due to their distributed nature, multi-agent system provides a convenient way to enable failure tolerance. This paper presents a multi-agent architecture where the agents are combined with an ontology and subjacent low-level based on IEC61499 standard in order to enhance fault tolerance in such...
A unified configuration interface is an important requirement for a heterogeneous distributed control environment as defined by IEC 61499. Most of the current IEC 61499 implementations solve this problem through the use of XML. Although XML is flexible, extensible, and human readable it has the main drawbacks of a great overhead and that it is elaborative to parse. A binary XML representation promises...
The aim of this paper is to describe a research roadmap for a multi-domain model-driven embedded systems design approach and the corresponding meta-model which is applicable to the domain of complex Industrial Automation and Control Systems (IACS). The special requirements of the industrial automation sector are taken into account by this novel approach, utilizing existing model-driven techniques...
Requirements of manufacturing systems are permanently changing. Therefore reconfiguration of their mechanical structure as well as their control software is inevitable. To reduce the time from specification to implementation a parallel development and implementation of hardware and software is the most promising approach. Modeling can act as specification of the desired plant behavior. These models...
Frequent changes in the production requirements demand for improvement of adaptation and modification ability of production systems. To address these requirements we propose a concept and system architecture in order to provide the reconfigurability of machine tool systems in assembly shop floor. This approach allows machines and plants to flexibly adapt themselves to changing demands and interact...

Transport systems of the future have to be flexible and adaptive in order to cope with failures and unexpected disturbances. Agent technology provides a good framework for handling with dynamics in large complex systems, using distributed control of the system increasing flexibility and enhancing fault tolerance. This paper researches how software agents supported with ontologies can improve the efficiency...
The need for agility in manufacturing systems is continuously growing. This is caused by increasing complexity and decreasing life cycles of the produced goods. This paper proposes a modular, reconfigurable manufacturing system, based on a distributed three layer architecture, consisting of mechatronic components, an IEC 61499 based distributed low level control and on top a multi agent system as...
The assembly process used by most manufacturers today is based on disconnected ordering, scheduling as well as execution processes, and lacks on agility needed for enterprise-wide integration. This paper presents a knowledge-based multi-agent framework to enhance the agility in assembly systems. Agents with specialized expertise and high level of autonomy cooperate together to accomplish individual,...
This paper presents an application of an ontology in combination with multi-agent technologies in a transport domain. The need for flexibility and agility in this domain is continuously growing due to the increasing complexity in the processes where this domain is used. The ontology, we propose, is shared among agents and provides the common agreement and understanding about the used concepts. This...
Currently applied autonomous power supplies are designed for specific energy demands and therefore rather inflexible. For an increased user friendliness, allowing attaching and detaching electrical devices without new load calculations, a flexible Power Distribution System is necessary. This can be reached by applying an Energy Management System. A concept for such a system, that is scalable by distributing...
Increasing complexity in the transport domain requires flexible and reconfigurable control architectures. In this paper we present the deployment of an agent-based system in this domain splitting the manufacturing control into two layers: a high level control based on agents and a low level control based on the standard IEC 61499. A further focus is laid on the design of a generic communication interface...
