Industrial Machines as a Service: A Model Based on Embedded Devices and Web Services

In the last years, the maturity reached by the Information and Communications Technologies (ICT) has led us to an scenario which is suitable for facing the new business models, arisen as a consequence of the adoption of the Internet as the basic development infrastructure: strengthen of relationships between organizations and also between each organization and its customers, access to new markets, new competition models and manufacturing procedures. The research presented in this article is centred in the last field, concretely in a new method which allows an integral eBusiness model, compatible with current proposals and capable of overcoming the physical and logistical constraints that prevent the manufacturing processes from taking advantage of the whole potential offered by new technologies in this field, which are already being used by other business areas.

Industrial Machines as a Service: Modelling industrial machinery processes

In this paper is proposed a service model for the industrial machinery which provides a design pattern which details, classifies and organises the services that ideally the machine should possess in order to facilitate its self-management and proactive management of the business logic for which it is responsible. This pattern also establishes those services which will enable the machine to communicate and cooperate with other machines or manufacturing elements, as well as with the remaining business processes. The proposed pattern are based on service oriented architecture (SOA) and Web services extensions (WS-*) in order to ensure that the industrial machinery attains high levels of self management and especially so that it can show the rest of the organisation and from a perspective of functionality, in a normalised manner, overcoming barriers imposed by technological and physical restrictions typical of these components and which traditionally have kept them isolated from the general business model.

A Computational Architecture Based on RFID Sensors for Traceability in Smart Cities

Information Technology and Communications (ICT) is presented as the main element in order to achieve more efficient and sustainable city resource management, while making sure that the needs of the citizens to improve their quality of life are satisfied. A key element will be the creation of new systems that allow the acquisition of context information, automatically and transparently, in order to provide it to decision support systems. In this paper, we present a novel distributed system for obtaining, representing and providing the flow and movement of people in densely populated geographical areas. In order to accomplish these tasks, we propose the design of a smart sensor network based on RFID communication technologies, reliability patterns and integration techniques. Contrary to other proposals, this system represents a comprehensive solution that permits the acquisition of user information in a transparent and reliable way in a non-controlled and heterogeneous environment. This knowledge will be useful in moving towards the design of smart cities in which decision support on transport strategies, business evaluation or initiatives in the tourism sector will be supported by real relevant information. As a final result, a case study will be presented which will allow the validation of the proposal.

Wake on LAN over Internet as Web Service

In this paper we present an approach based on the use of embedded network devices for the deployment of small network services, such as DHCP, BOOTP, filters or very specific proxies. The novelty of the proposal resides in the very reduced size of the devices, in that every device is specialized in a certain network function, and specially designed to operate with minimum maintenance, and in the fact that they are presented under both conventional (client-server) and more open (SOA) standards, more concretely, as Web services. At the same time, these embedded services can work in an individual way or in collaboration with other enterprise network services, either provided by means of conventional systems or by means of other embedded devices. To specify the proposal, we have chosen as example an embedded device able to manage the remote boot of network nodes by means of wake on LAN (WoL) through Internet.

Distributed Robotic Architecture based on Smart Services

This paper presents an approach for designing robots and robotic systems based on the application of models, architectures, techniques and tools that have contributed valid solutions in other areas, such as e-business. Before applying these solutions, the physical elements that make up a robotic system are subjected to a normalization process in order to characterize their functional contributions. In this way, the conceptual model and the technical architecture of the service-oriented architecture robotic system is established. The paper also includes a simple implementation enabling the proposal to be validated, together with the main conclusions reached and future lines of study.

Normalization of Industrial Machinery with Embedded Devices and SOA

In the present paper we propose a method that permits visualization of manufacturing devices from a functional perspective. The aim of this method is to raise the abstraction level of manufacturing devices from the lower levels of production to the enterprise level of the business model. The target of this new approach is to integrate in a transparent way the resources, processes and, in general, the business logic of manufacturing levels using existing business models and achieving business continuity and process automation. The proposed method comprises two phases: the first phase that we have named industrial machinery normalization process; and the second phase that we have named manufacturing processes reorganization process. This paper focuses mainly on the former, i.e. specification of the hardware normalization and industrial machinery functionalities process.

Wireless sensor networks and service-oriented architecture, as suitable approaches to be applied into ITS

In this paper, Wireless Sensor Networks (WSN) and Service-Oriented Architecture (SOA) approaches are analyzed given that represent both emerging and key role for Intelligent Transportations Systems (ITS). However, It is worth noting that WSN and SOA approaches have begun to be applied into ITS separately and day by day these approaches tend to be combined to get the best outcomes for both safety and security for ITS applications. For this reason, a discussion of the principals ITS applications of these two approaches and a case study, that has been designed and implemented to illustrate their advantages, are presented. The case study is focused on support a very useful ITS service associated with the localization of parking spaces.

Wake on LAN Over the Internet as Web Service System on Chip

In this paper, we introduce a system on chip designed to run a particular Web service (WS) in an application-specific integrated circuit. The system has been designed devoid of processor and software and conceived as a hardware pattern for a trouble-free design of network services offered as WS in a service-oriented architecture (SOA). Therefore, the chip is not only able to act as a Simple Object Access Protocol service provider but also capable of registering the service on its own in an external broker server using the Universal Description, Discovery and Integration Standard publication protocol. This proposal has been named WS on chip, and its main goal is to implement more cost-effective and zero-management SOA network devices. To validate this approach, a prototypical device has been developed using a field-programmable gate array technology. The particular network service selected has been Wake on LAN (WoL) over the Internet, thus allowing any WS client to wake up any network node compatible with WoL technology. A full SOA scenario has also been developed to test the prototype functionalities and show the proposal validity.

Semantic processes modelling independent of manufacturing infrastructures

This paper presents a proposal enabling the modelling of manufacturing processes independently of the structure and composition of the industrial plant where these processes will ultimately be implemented. The rationale for the proposal is in the incorporation of knowledge, supported by ontologies regarding manufacturing processes, industrial machinery and the industrial plants involved. With this knowledge, process engineers can focus their efforts exclusively to define the activities to be performed on the raw material (abstract model), allowing the system to infer what other activities should be incorporated in the abstract model to obtain a particular manufacturing process tailored to a particular industrial plant. To refine the proposal, a case study is put forward in which the management system was able to infer the way for the raw material to be processed according to the abstract model and automatically composed the activities necessary for achieving it. Finally, an implementation of this management system for processes is presented together with the design of two models of industrial plant that demonstrate the validity of our proposal.

New models of agile manufacturing assisted by semantic

This paper proposesa process management system that enables new dynamic manufacturing models to be implemented. This system facilitates the automation of process modelling, thus reducing the workload for process engineers. To this end, it focuses on the incorporation of knowledge in the definition of the processes and services involved. The document presents a general scenario in which industrial machinery is offered as services (IMaaS), integrated under a Service-oriented Architecture (SOA); this is followed by a definition of an ontology that enables the incorpoation of knowledge into the proposed scenario; finally the implementation of a prototype, along with a test scenario, is presented, enabling the viability of the proposal to be demonstrated.
