Engineering of service-oriented automation systems: a survey

The evolution of manufacturing systems and the emergence of decentralised control require flexibility at various levels of their lifecycle. New emerging methods, such as multi-agent and service-oriented systems are major research topics in the sense of revitalizing the traditional production procedures. This paper takes an overview of the serviceoriented approach in terms of platform and engineering tools, from the perspective of automation and production systems. From the basic foundation to the more complex interactions, service-oriented architectures and its implementation in form of web services provide diverse and quality proved features that are welcome to different states of the production systems’ life-cycle. Key elements are the concepts of modelling and collaboration, which enhance the automatic binding and synchronisation of individual low-value services to more complex and meaningful structures. Such interactions can be specified by Petri nets, a mathematically well founded tool with features that enhance towards the modelling of systems. The right application of different methodologies together should motivate the development of service-oriented manufacturing systems that embrace the vision of collaborative automation.The authors would like to thank the European Commission and the partners of Network of Excellence “Innovative Production Machines and Systems” (http://www.iproms.org/) and the SOCRADES project (http://www.socrades.eu) for their support.info:eu-repo/semantics/publishedVersio

Petri net-based approach for web service automation resource coordination

In industrial automation, control systems and mechatronic devices are from diverse nature, supplied by different manufacturers and made of different technologies. The adoption of web services principles in an automated production system satisfies some requirements, namely the interoperability of such heterogeneous and distributed environments and the basis for flexibility and reconfigurability. Manufacturing processes require to access resources at different precedence levels and time instances, but in the other way resources may also be shared by different processes. A major challenge is then how individual services may interact, coordinating their activities. Petri nets may be used to describe complex system behaviour and therefore also applied to coordinate such systems. The paper introduces a Petri net based approach for the design, analysis and coordination of systems developed using web services to represent individual and autonomous resources. For this purpose, it is presented a Petri nets computational tool to support the design, validation and coordination of web service based automation systems.info:eu-repo/semantics/publishedVersio
