Reliable and secure communications infrastructure for virtual enterprises

The virtual enterprise paradigm is the key for small and medium enterprises (SMEs) to enter into the business-to-business electronic commerce. Nevertheless SMEs require a reliable infrastructure connecting transparently to the global network of enterprises their IT application tools implementing the internal business processes. Such infrastructure is deeply grounded on a communication infrastructure that might offer operative and management mechanisms able to cope with the complexity of the underlying heterogeneous computational and communication available resources. Beyond information communication security (privacy, integrity, and authentication), an operating reliable infrastructure to manage information communication is required. The SME business cannot support the great vulnerability to failures presented by a distributed system made of heterogeneous technologies. The PRODNET Communication Infrastructure aims to offer beyond a secure and high availability communication infrastructure, a set of features to cope with such distribution and heterogeneity implemented by a flexible communication management module. Considering that SMEs do not have their own IT support, the PRODNET Communication Infrastructure also offers remote management/maintenance capabilities.

A web services-based approach to develop a networked information integration service platform for gear enterprise

In order to deal with the problems of information integration and data sharing across distributed heterogeneous application systems in gear enterprises, it is imperative to build up a high quality information integration platform. Web Services, an emerging form of service-oriented architecture (SOA) for distributed computing, have the potential to serve as a key enabling technology to integrate heterogeneous systems under the distributed environment. This paper presents a novel information integration service platform which offers better support for the networked manufacturing of gear enterprise by taking full advantage of technologies of SOA and Web services. In this paper, the information integrated operation mode of gear enterprise networked manufacturing is deeply analyzed and the functional architecture of the networked information integration service platform is proposed. Furthermore, the application integrated framework of gear enterprise is constructed and the software architecture of the service platform is implemented in the .NET environment. Finally, an actual application example of hypoid gear networked manufacturing is provided to demonstrate the practicability of the proposed platform.

Design of a Meta Model for integrating enterprise systems

In the rapidly changing environment of the knowledge economy, an enterprise must respond to potential future changes when developing and implementing enterprise systems, which must be thus flexible and integrateable. The paper presents a method for integrating distributed Relational Database Management Systems (RDBMS) with the backend of enterprise systems developed by various software vendors. This method, with a Meta Model as the core integration technology, will enable enterprise systems to meet the demands of system integration, and to achieve, based on XML document standards, information integration. The method of integration is sufficiently flexible and expandable to integrate existing enterprises systems as well as systems that may be introduced into enterprises in the future. The study, which takes an on-line purchase system for electronic commerce as an example of the use of the proposed Meta Model, addresses the integration of enterprise resource planning (ERP) systems to achieve enterprise resources sharing, shorten purchase time and lower operation cost.

Cyber-physical systems challenges: a needs analysis for collaborating embedded software systems

Embedding computing power in a physical environment has provided the functional flexibility and performance necessary in modern products such as automobiles, aircraft, smartphones, and more. As product features came to increasingly rely on software, a network infrastructure helped factor out common hardware and offered sharing functionality for further innovation. A logical consequence was the need for system integration. Even in the case of a single original end manufacturer who is responsible for the final product, system integration is quite a challenge. More recently, there have been systems coming online that must perform system integration even after deployment—that is, during operation. This has given rise to the cyber-physical systems (CPS) paradigm. In this paper, select key enablers for a new type of system integration are discussed. The needs and challenges for designing and operating CPS are identified along with corresponding technologies to address the challenges and their potential impact. The intent is to contribute to a model-based research agenda in terms of design methods, implementation technologies, and organization challenges necessary to bring the next-generation systems online.     

Editorial: Internetware of the Age

While the infrastructure of computing shifting from isolated computers to Internet-linked resources, the software industry transfers its focus from computing products to dependable services. That''s one of the reasons why pervasive computing, grid computing, service computing and cloud computing are introduced on the open and dynamic Internet-linked platform. The communication abilities it introduced enable various resources exchanging and sharing freely, and participating in the community in the social network. There are three layers in such a platform: computing infrastructure, software services and information web. The underline layer, computing infrastructure, provides computing and communication facilities, and the surface layer, information web, is full of information recombination and consuming. The layer of software services serves as a factory to process constantly emerging and heterogeneous dynamic information using distributed, autonomous, and evolvable computing facilities. Therefore, services provided by such software systems should be adaptive, situational, trustworthy, autonomous and etc. To achieve flexible objectives, these services can be coordinated in various styles such as integration, cooperation, orchestration and etc. A portmanteau term \Internetware" is used     

Everything-as-a-service platform for on-demand virtual enterprises

While constructing virtual enterprises, it is crucial to flexibly integrate heterogeneous business resources and processes of different business partners and make them collaborate dynamically. Keeping involved IT systems or components as autonomous and loose-coupled services, the “Everything as a Service” concept supports flexible integration of heterogeneous applications. We adopt this concept and analyze the challenges in virtual enterprise construction, then propose a service platform for on-demand virtual enterprises. The platform supports flexible integration of networked resources, and facilitates virtual enterprise construction with business process utility, trusted service composition and data service centric business collaborations. At the end of the paper, together with a case study, experimental evaluations in contexts of concurrent multi-users are presented, showing the effectiveness and performance of the platform.
