Changes in electricity markets, driven by the increased use of renewable energy resources and the active participation of consumers in managing their energy usage, creates a demand for new smart grid technologies and services. In this paper, we describe an architecture that has been developed within the EU-funded Nobel Grid project, integrating novel smart grid solutions and services to enable energy...
This paper presents an approach for detecting and tackling obstacles that could fail the execution of social business processes. Existing approaches target regular (non-social) business processes and thus, rely mainly on business logs that contain details such as who executes what, when, and where. However, interactions between a business process's three components namely task, machine, and person,...
Companies are increasingly incorporating commercial Business Process Management Systems (BPMSs) as mechanisms to automate their daily procedures. These BPMSs manage the information related to the instances that flow through the model (business data), and recover the information concerning the process performance (Process Performance Indicators). Process Performance Indicators (PPIs) tend to be used...
Today, the main limit for an efficient exploitation of resources owned by one or more IaaS environments is not technical, but structural: users and providers have two different views that rarely are really integrated. Cloud users have a deep knowledge about their workflows, but they don't have any details about the real state of the IaaS physical resources. Cloud providers have the opposite problem:...
Enterprises face the challenge of rapidly adapting to dynamic business environments. The traditional approach to process management is only partially appropriate to this new context, and calls for the advent of new, evolutionary business processes. This new approach attempts to address specific issues related to flexibility and adaptation such as design of easily adaptable processes, dynamic handling...
This paper describes novel methodologies for assessing benefits and impact creation in IST related research projects. The paper first includes a Verification & Validation (V&V) method developed for evaluating of Future Internet software components implementation in a multi-sectorial environment. The proposed approach is based on best of breed V&V methodologies characterized by a structured...
Provenance of electronic data is an important piece of the metadata of a data object. Making systems provenance-aware can greatly benefit all parties involved. This paper discusses the importance of data provenance and presents an open cloud architecture named CloudProv, a framework to integrate, model, and monitor the provenance data. Our elastic cloud architecture will provide an open APIs which...
People-driven service engagements involve communication over channels such as chat and email. Such engagements should be understood at the level of the commitments that the participants create and manipulate. Doing so provides a grounding for the communications and yields a business-level accounting of the progress of a service engagement. Existing work on commitment-based service engagements is limited...
The use of information technology in research and practice leads to increased degree of automation of tasks and makes scientific experiments more efficient in terms of cost, speed, accuracy, and flexibility. Scientific workflows have proven useful for the automation of scientific computations. However, not all tasks of an experiment can be automated. Some decisions still need to be made by human users,...
We present an integrated approach to design, monitor and manage the lifecycle of applications based on the Service Oriented Architecture (SOA) principles and capable of taking advantage of cloud computing environments. The integrated framework takes profit of publicly available open source tools and standards in an effective and coherent way, and covers the steps from business and architectural design...
Enterprise applications today are composed of multiple independently executing services and processes that collectively provide a solution to a business problem. These composite applications contain a heterogeneous collection of services that execute in a variety of runtimes making them difficult to manage while maintaining a business centric point of view, as opposed to a service point of view. This...
Criminals have shown adaptability and opportunism in finding the new and innovative methods that use the internet, wireless device for electronic cross-border funds transfer globally. That is a challenge to the central banks. the present study analyses the new E-payment vectors with a focus on: (1) assess the methods of the central bank in China used for monitoring the suspicious money flowing; (2)...
As empresas buscam sua sustentabilidade desenvolvendo, cotidianamente, novas estratégias de negócios. O incentivo natural para a persistência nessa busca, comum no meio dos negócios, é a globalização. O sucesso dessas estratégias acaba atraindo investidores, pois corrobora com o retorno para seus investimentos. Nesse processo, a segurança das informações garante um alicerce estável para o desenvolvimento...
Enterprise business strategy and IT strategy is disjointed, which leads to the failure of many IT projects. The main reason of failure is lack of IT Enterprise architecture development at the initial stage of enterprise informatization. This paper discusses the content of IT planning, enterprise architecture and their relationship, and expounds the process of enterprise architecture development using...
Sophisticated event-pattern rules are the key to successful applications of Complex Event Processing (CEP). However, creating such rules may place heavy demands on business users. In this paper we propose a novel approach to rule composition for the event-based system SARI: Via a web-based user interface, users can compose ruling logic from abstracted, configurable buildings block as previously prepared...
This paper presents a reference model for Event Driven Composite Services, shows how such a model can be used as a basis to design a Service Creation Platform and a Service Execution Platform and describes an example of a Composite Service that takes advantage of the model and of the platforms. The Event Driven Service Composition paradigm supports the design and the implementation of distributed...
In order to effectively monitor the application of the network performance and service quality, rapidly response users' needs and complaints, telecom operators find that the demands for service quality are in an urgent case. According to the requirement analysis on quality monitoring for streaming media service, together with the characteristics of stream media transport protocol, this paper introduced...
The use of heterogeneous distributed systems, such as Clusters of Clusters (CoC) and computational grids, enables the development of complex computational systems. However some of these systems require services to be easily composed and executed while maintaining the dependencies among them; both the services and the dependencies can be represented as workflows. Moreover, Web Services have been adopted...
The rapidly growing service-oriented economy has highlighted key challenges and opportunities in ICT-supported service and product lifecycle management. From a service consumer point of view there is no standardized way to locate, evaluate, negotiate and monitor services. Composition of third party services is fraught with uncertainty due to absence of definitive SLAs. Moreover, there is a lack of...
The European Commius Project aims at enabling small and medium enterprises (SMEs) to collaborate easily on the level of system, semantic and process interoperability by just the use of e-mail communication. This will be achieved by enrichment of incoming e-mails, depending on their contents (semantic interoperability), with additional information. Furthermore, recommendations of expedient further...
