Currently employed manufacturing systems are very often historically grown systems that can comprise several different technologies of control software. Linking these diverse control subsystems in the manufacturing domain is therefore of vital importance to ensure the system's functionality. In this paper we introduce an agent-based approach with agents(More)
Multi-agent systems have proven to be a powerful technology for improving flexibility and agility in a complex manufacturing environment. In such systems, an ontology is a crucial element for knowledge representation of the external environment or the agent's domain of application as well as for ensuring interoperability between agents. The agent's decision(More)
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(More)
This paper presents a decentralized approach for the local reconfiguration of control software, which is based on a multiagent system with ontology-driven reasoning. We apply this approach to a transportation system and demonstrate improvements on efficiency, fault tolerance and stability with several experiments. One key element to achieve these results is(More)
Manufacturing systems have become very complex, and the traditional hierarchical and centralized approaches are not adequate any more. Decentralized approaches are considered promising, but they are not yet sufficiently understood for widespread industrial application. In particular, agent-based control has not yet achieved its potential, so that more(More)
Automation systems (ASs) based on Service-Oriented Architecture (SOA) are becoming more wide-spread. Due to their inherent property of separating the hardware-specific implementation from the logical work- or control-flow, SOA-based application programming is regarded as the next logical step in AS programming. Several successful attempts for implementing(More)
During the last decades production automation research has been focused on improving the flexibility and adaptability in order to cope with the arising challenges of mass customization. Much work was devoted to the higher—planning and scheduling—levels of automation systems. However, the lower level real-time control infrastructure was widely(More)
Providing, operating and maintaining the infrastructure for continuously growing and changing electric energy systems are the technological key challenges for our society in the next years and decades. Multi-Agent Systems represent a promising approach able to realize/implement the above described functionalities and services in a power distribution(More)
