Intelligent business processes composition based on mas, semantic and cloud integration (IPCASCI)
[EN]Component reuse is one of the techniques that most clearly contributes to the
evolution of the software industry by providing efficient mechanisms to create quality
software. Reuse increases both software reliability, due to the fact that it uses
previously tested software components, and development productivity, and leads to a
clear reduction in cost.
Web services have become are an standard for application development on cloud
computing environments and are essential in business process development. These
services facilitate a software construction that is relatively fast and efficient, two
aspects which can be improved by defining suitable models of reuse. This research
work is intended to define a model which contains the construction requirements of
new services from service composition. To this end, the composition is based on
tested Web services and artificial intelligent tools at our disposal.
It is believed that a multi-agent architecture based on virtual organizations is a
suitable tool to facilitate the construction of cloud computing environments for
business processes from other existing environments, and with help from ontological
models as well as tools providing the standard BPEL (Business Process Execution
Language). In the context of this proposal, we must generate a new business process
from the available services in the platform, starting with the requirement
specifications that the process should meet. These specifications will be composed of a
semi-free description of requirements to describe the new service.
The virtual organizations based on a multi-agent system will manage the tasks
requiring intelligent behaviour. This system will analyse the input (textual description
of the proposal) in order to deconstruct it into computable functionalities, which will
be subsequently treated. Web services (or business processes) stored to be reused
have been created from the perspective of SOA architectures and associated with an
ontological component, which allows the multi-agent system (based on virtual
organizations) to identify the services to complete the reuse process.
The proposed model develops a service composition by applying a standard BPEL
once the services that will compose the solution business process have been
identified. This standard allows us to compose Web services in an easy way and
provides the advantage of a direct mapping from Business Process Management

Construction safety and digital design: a review
As digital technologies become widely used in designing buildings and infrastructure, questions arise about
their impacts on construction safety. This review explores relationships between construction safety and
digital design practices with the aim of fostering and directing further research. It surveys state-of-the-art
research on databases, virtual reality, geographic information systems, 4D CAD, building information
modeling and sensing technologies, finding various digital tools for addressing safety issues in the
construction phase, but few tools to support design for construction safety. It also considers a literature on
safety critical, digital and design practices that raises a general concern about ‘mindlessness’ in the use of
technologies, and has implications for the emerging research agenda around construction safety and digital
design. Bringing these strands of literature together suggests new kinds of interventions, such as the
development of tools and processes for using digital models to promote mindfulness through multi-party
collaboration on safet
Integrating security solutions to support nanoCMOS electronics research
The UK Engineering and Physical Sciences Research Council (EPSRC) funded Meeting the Design Challenges of nanoCMOS Electronics (nanoCMOS) is developing a research infrastructure for collaborative electronics research across multiple institutions in the UK with especially strong industrial and commercial involvement. Unlike other domains, the electronics industry is driven by the necessity of protecting the intellectual property of the data, designs and software associated with next generation electronics devices and therefore requires fine-grained security. Similarly, the project also demands seamless access to large scale high performance compute resources for atomic scale device simulations and the capability to manage the hundreds of thousands of files and the metadata associated with these simulations. Within this context, the project has explored a wide range of authentication and authorization infrastructures facilitating compute resource access and providing fine-grained security over numerous distributed file stores and files. We conclude that no single security solution meets the needs of the project. This paper describes the experiences of applying X.509-based certificates and public key infrastructures, VOMS, PERMIS, Kerberos and the Internet2 Shibboleth technologies for nanoCMOS security. We outline how we are integrating these solutions to provide a complete end-end security framework meeting the demands of the nanoCMOS electronics domain
Knowledge management : critical perspectives on e-business activities
This article is both a review and an agenda-setting piece. It argues that knowledge management suffers from conceptual and definitional ambiguity, oversimplification of its development processes, and methodological limitations. Nevertheless, there is a consensus in business and academia that knowledge is a key component of success and allows firms to achieve and sustains competitive advantages. In a digital era, these advantages arise from the potential of data and information that can be gathered, processed, shared, and used to improve e-business activities. Thus, this research bridges the gap in the assessment of knowledge management and e-business relationship, by applying an SEM to a large database sample of KM activities performed by European firms.N/
Restoring Trust Relationships within Collaborative Digital Preservation Federations
4th International Conference on Open RepositoriesThis presentation was part of the session : Conference PresentationsDate: 2009-05-19 01:00 PM – 02:30 PMThe authors extend their process for creating and establishing trust relationships to include steps for restoring trust relationships after catastrophic events. Part of this model will include best practices for business continuity relationships and will integrate trust models from Holland and Lockett (1998) and Ring and Van de Ven (1994) and how they can be applied to a process for trust restoration after periods of disaster or critical data loss. These models provide key frameworks for understanding how trust can be utilized for collaborative start points as well as for collaborative recovery points from physical natural disaster or critical data loss
Acquiring and Applying Knowledge in Transnational Teams: The Roles of Cosmopolitans and Locals
This paper examines the roles of cosmopolitans and locals in transnational teams that work on knowledge-intensive projects. I propose that cosmopolitan and local team members can help their teams to acquire and apply knowledge more effectively, by bringing both internal and external knowledge to their teams and enabling them to more successfully transform this knowledge into improved project performance. Findings from a study of 96 project teams at an international development agency reveal that the roles of cosmopolitans and locals were complex and sometimes valuable, but cosmopolitans offered greater benefits than locals and too many of each could hurt. Implications for theory and research on international management, virtual teams, exploration and exploitation, and organizational knowledge are discussed
Improving supply chain management in construction: what can be learned from the aerospace industry?
In order to provide for controllable delivery, reliable lead times and efficient customer response, lean manufacturing and platform assembly practices play an important role in supply chains in the aerospace industry. The adoption of lean manufacturing practices ensures an efficient delivery of products to the market. Benefits from the development of platform strategies are a more reliable materials supply and an improved logistics control. The aerospace industry is characterized by a small number of major global players and many small ones. A major part of the design and production has been contracted out to suppliers. In this paper the basic similarities and differences between the construction and aerospace industry and supply chains are analysed. A comparative study of aerospace and construction supply chains is presented to indicate and discuss the applicability of supply chain management concepts to construction, and the improvement potential of these concepts regarding supply chain management in construction. It is concluded that in particular the practice of platform assembly is a fruitful concept to be applied in the construction industry
