Integration of virtual and real environments for engineering service-oriented manufacturing systems

Engineering frameworks are currently required to support the easy, low-cost, modular and integrated development of manufacturing systems addressing the emergent requirements of re-configurability, responsiveness and robustness. This paper discusses the integration of 2D/3D digital software tools with Petri net based service-oriented frameworks to allow the design, configuration, analysis, validation, simulation, monitoring and control of manufacturing systems in a virtual environment and its posterior smooth migration into the real "physical" environment. An experimental case study was implemented to validate the proposed concepts, using the Continuum platform to design, compose, analyze, validate and simulate the Petri nets based service-oriented manufacturing control system, and the Delmia AutomationTM software suite to support the rapid prototyping and the easy simulation of the designed control solution. The experimental results prove several aspects of the proposed approach, notably the smooth migration between the design and the operation phases, one of the main objectives of the work.

Leveraging the Agility of Manufacturing Chains by Combining Process-Oriented Production Planning and Service-Oriented Manufacturing Automation

AbstractGlobalization, rising product variety, the need for continuously improving productivity and quality demand higher agility of manufacturing systems. Well-known principles like encapsulating functionality into mechatronic systems to enable reuse and standardization are basic approaches to gain agility in manufacturing environments. However, there is a lack of a holistic communication architecture for manufacturing systems and an overall concept to organize the continuously changing production planning and control processes. The paradigm of service-oriented architectures emerged as a concept to increase the flexibility and reuse within IT environments by using software modules with standardized communication interfaces. Transferring this paradigm to the field of manufacturing offers a unique opportunity to complement the advances of standardized communication interfaces and mechatronic encapsulation with powerful production planning and control methods.In this paper the central aspects and the potentials of transferring service-oriented paradigms from IT to automation are discussed. The methodology of process-oriented manufacturing planning is presented as the organizational fundament for an efficient establishment of service-oriented manufacturing systems. An approach for a process-oriented factory model is presented as the basis for a process-oriented planning process. Furthermore, a technical demonstrator that provides the opportunity for evaluating SOA technologies and our new planning approach is shown.

Solving Myopia in Real-time Decision-making using Petri nets Models’ Knowledge for Service-oriented Manufacturing Systems

Abstract This paper introduces a novel approach to the real-time decision-making in service-oriented manufacturing systems, addressing the myopia problem usually presented in such systems. The proposed decision method considers the knowledge extracted from the Petri nets models used to describe the services process behavior, mainly the T-invariants, combined with a multi-criteria function customized according to the system's particularities and strategies. An experimental laboratorial case study was used to demonstrate the applicability of the proposed real-time decision-making approach in service-oriented manufacturing systems, considering some productivity and energy efficiency criteria.

A new conceptual architecture to enable iPSS as a key for service-oriented manufacturing executive systems

Service-oriented machining powered with industrial product service systems in workshop level is a quite new research topic. To clarify its real mechanism hidden, four phenomena of running the service-oriented machining are firstly analysed. And then a conceptual architecture to implement a service-oriented manufacturing system which uses the service-oriented machining is put forward. A simple case study shows the methods mentioned in the paper is feasible and reasonable.
