Supervisory control and data acquisition for virtual enterprise

The new manufacturing paradigms, such as agile manufacture and lean production, are leading industrial countries towards the new generation of concurrent enterprises involving virtual enterprise architecture and concurrent engineering extended methodology. Continuing adaptation to the market can only be achieved efficiently if the planning and control processes are both optimized horizontally (Automatic Control Systems) and vertically (Management Control Systems). The desired improvement in performance and the realization of global enterprise objectives require a tight integration of the units of the enterprise. The close monitoring of the operational performance of various plants, manufacturing shop-floors/cells/machines, as well as their associated instrumentation and control is of increasing strategic importance. Failures can lead to increased costs and reduced product quality, consistency and production, and to plant shutdowns and increased environmental impact. There is a real need for advanced monitoring technologies to be applied, and their potential demonstrated, on complex industrial plants. The planning and scheduling of manufacturing systems integrated into virtual enterprise architectures requires the implementation of new General Master Production Planning and Scheduling techniques and Supervisory Control and Data Acquisition (SCADA) functions. This paper discusses some key issues on the SCADA-oriented open system for virtual enterprise architecture.

Towards Integration of Knowledge Extraction from Process Interoperability in Future Internet Enterprise Systems

Abstract Current R&D directions sustained by the European Commission, by FP7 and in the near future by FP8 research programs, are focusing on the development and standardization of new technologies to sustain the “Future Internet”. In this context the development of new Internet related concepts and technologies oriented towards providing positive benefits for economy has been included in a broad concept of “Future Internet Based Enterprise Systems”. The Intelligent Manufacturing Systems (IMS) paradigms, are leading our Information Society towards New Economy-driven Knowledge Society copying with Global e-Markets new list of System of Systems requirements. Efficient interoperability, both horizontal and vertical, is a basic requirement towards the aim of Enterprise System Integration within Collaborative Concurrent Competitive Enterprises. In this context, the authors will propose a framework for web service composition and knowledge extraction form process execution based on process description embedded in Internet of Things compliant intelligent objects.

Intelligent agent-based control systems in manufacturing

The paper presents a real-time supervisory control architecture for large-scale manufacturing systems. The architecture is based on autonomous intelligent agents at the shop-floor level, organized in dynamical, reconfigurable structures depending on the manufacturing systems state and goals. The supervisory level is introduced in order to evaluate and improve the performances of the control architecture. Functioning of the whole architecture is event-driven and based on rules that the supervisor should be capable of completing. The formal support for performance evaluation and control policies synthesis is DES.

E-Services quality assessment framework for collaborative networks

In a globalised networked economy, collaborative networks (CNs) are formed to take advantage of new business opportunities. Collaboration involves shared resources and capabilities, such as e-Services that can be dynamically composed to automate CN participants’ business processes. Quality is essential for the success of business process automation. Current approaches mostly focus on quality of service (QoS)-based service selection and ranking algorithms, overlooking the process of service composition which requires interoperable, adaptable and secure e-Services to ensure seamless collaboration, data confidentiality and integrity. Lack of assessment of these quality attributes can result in e-Service composition failure. The quality of e-Service composition relies on the quality of each e-Service and on the quality of the composition process. Therefore, there is the need for a framework that addresses quality from both views: product and process. We propose a quality of e-Service composition (QoESC) framework for quality assessment of e-Service composition for CNs which comprises of a quality model for e-Service evaluation and guidelines for quality of e-Service composition process. We implemented a prototype considering a simplified telemedicine use case which involves a CN in e-Healthcare domain. To validate the proposed quality-driven framework, we analysed service composition reliability with and without using the proposed framework.

From industrial robotics towards intelligent robotic systems

The advanced research in robotics scientific discipline has produced a paradigm shift from the classical robot manipulator used only in industrial environment to the modern mobile robot viewed as an every day life ldquopartnerrdquo. This first objective of this paper is to offer a short but comprehensive history of the paradigm shifts that triggered the industrial robotics research advancements. The short list of paradigm shifts that are to be discussed include: computer integrated manufacturing and engineering systems (C.I.M.E. - 1976), flexible manufacturing systems (FMS - psila80), lean manufacturing (psila90), agile manufacturing, fractal and/or holonic manufacturing systems (psila90), intelligent manufacturing systems (2000). The second objective is to discuss generic design principles and architecture guidelines for the development of a complex robotic system. These include collaborative robotics, artificial intelligence, human-robot interaction, multi-agent systems, service oriented architecture.

Dynamic Interoperability Model for Web Service Choreographies

Service compositions automate a business process allowing organizations to develop value added products. Service choreographies are collaborative in nature and allow for direct interactions between parties involved. Interoperability and adaptability remain challenges in executing a successfull service composition based on choreography. The paper proposes a dynamic model that solves interoperability issues at all levels in an adaptable manner.

From Mass Production to Intelligent Cyber-Enterprise

The paper proposes a new paradigm for the enterprise of the future, with respect to the requirements and the constraints it will be forced to face in order to progress and evolve. It is a paradigm which will take into account not only the complex relations between enterprise components - human, material and informational, but also the integration enterprise-society will all its aspects. There are presented some of the main trends in the control and management of manufacturing systems, in order to enlighten the evolution of the concepts towards that of Cyber-Physical Systems, which is the core of the proposed paradigm. A generic model of the next generation of Manufacturing Systems will be introduced, based on the paradigm of Intelligent Cyber-Enterprise.

Knowledge Management Based Supply Chain in Learning Organization

Abstract The rapid increasing global systems complexity within the Knowledge Based Economy, the driver for the new coming Knowledge Society, provides “great challenges” to be undertaken within the innovative thinking in diversity. The authors goal within the present paper is to conceptualize the skills formation using a Knowledge Society paradigm approach to ensure efficient synchronization between the Adaptive Virtual Organization and Knowledge Management concepts by identifying a set of common activities performed with the aim of assisting the Adaptive Virtual Organization in meeting the going demand for knowledge of todays global economy. Therefore the need for implementing a Learning Organization concept as to offer the needed support within the Enterprise Information System Supply Chain Management becomes a great necessity.

Towards the development of semantically enabled flexible process monitoring systems

In current business and enterprise environment, the most common processes are structured and well-documented, but there is another important category of processes, also referred to as being ‘flexible’ or ‘less-structured’, because their execution is not strictly enforced by an external system. The main objective of this article is the design of a semantically enabled system capable of monitoring and analysing flexible or transient processes that typically occur in enterprise environments, in which the human factor plays a very important role in the execution and planning of activities. In order to facilitate the development of such a system, we provide a framework for the management of processes that also involve physical activities thus extending the scope of business process management into physical systems. This undertaking involves the integration of results from the emerging Cyber Physical Systems (CPS) research field and from several other areas of research such as the area of and activity recognition, plan recognition, process mining, etc.
