    Abstract. In order to help businesses to communicate fruitfully, we present a solution based on ontology alignment for integrating business documents. We focus on detecting and resolving semantic conflicts encountered during the integration process due to different terminologies used in xCBL, cXML and RosettaNet. Our contribution is to benefit from research in the ontology alignment area and considered as empirical study to test if alignment solution can overcome the heterogeneity problems between business systems. As case study, we apply alignment on purchase order ontologies, a common task of the supply chain

    Impact Evaluation of Interoperability Decision Variables on P2P Collaboration Performances

    This article deals with the impact evaluation of interoperability decision variables on performance indicators of business processes. The case of partner companies is studied to show the interest of an Interoperability Service Utility (ISU) on business processes in a peer to peer (P2P) collaboration. Information described in the format and the ontology of a broadcasting entity is transformed by ISU into information with the format and the ontology of the receiving entity depending on the available resources of interoperation. These resources can be human operators with defined skill level or software modules of transformation in predefined languages. A design methodology of a global simulation model for estimating the impact of interoperability decision variables on performance indicators of business processes is proposed. Its implementation in an industrial case of collaboration shows its efficiency and its interest to motivate an investment in the technologies of enterprise interoperability

    Towards a collaborative MRP for supply chain coordination

    Get PDF
    The necessity to increase collaboration in nowadays supply chains is emphasized both by academics and practitioners, but most of the supply chains are still managed through cascades of classical MRP/MRP2 systems. Interviews in the aeronautical sector have shown us the existence of many hidden practices aiming at satisfying local constraints which would be better addressed through collaborative processes. We suggest in this communication to define a "collaborative MRP" which would not only provide a better global performance than purely local planning, but take into account the autonomy of the involved partners which is not always respected by centralized pproaches using APS (Advanced Planning Systems)

    Evaluation of an Internet Document Delivery Service

    An Internet-based Document Delivery Service (DDS) has been developed within the framework of the CNR ( the Italian Research National Council) Project BiblioMIME, in order to take advantage of new Internet technologies and promote cooperation among CNR and Italian university libraries. Adopting such technologies changes the traditional organisation of DDS and may drastically reduce costs and delivery times. An information system managing DDS requests and monitoring the temporal evolution of the service has been implemented, running on the local-area network of a test-site library. It aims to track number and types of documents requested and received, user distribution, delivery times and types (surface mail, fax, Internet), to automate repetitive manual procedures and to deal with the various accounting methods used by other libraries. Transmission of documents is carried out by means of an e-mail/Web gateway system supporting document exchange via Internet, which assists receiving libraries in retrieving requested documents. This paper describes the architecture and main design features of the e-mail/Web gateway server (the BiblioMime server). This approach permits librarians to continue using e-mail service to send large documents, while resolving problems that users may encounter when downloading large size files with e-mail agents. The library operator sends the document as an attachment to the destination address; on fly the e-mail server extracts and saves the attachments in a web-server disk file and substitutes them with a new message part that includes an URL pointing to the saved document. The receiver can download these large objects by means of a user-friendly browser. We further discuss the data gathered during the triennium 1998-2000; this consists of about 5,000 DDS transactions per annum with 300 other Italian scientific and bio-medical libraries and commercial document suppliers. Use of the instruments described above allowed us to evaluate the performance of service “before” and “after” the use of Internet Document Delivery and to extract some critical data regarding DDS. Those include: a) libraries with which we have greater numbers of exchanges and their turnaround times; b) extraordinary reduction in costs and delivery times; c) the most frequently requested serial titles (allowing cost-effective decisions on new subscriptions); d) impact on DDS of library participation in consortia which allow user access to greater numbers of online serials

    CONSTRUCTION PARTNERING: MOVING TOWARDS THE RATIONALISATION FOR A DOMINANT PARADIGM

    Get PDF
    This paper critically reviews seminal literature on ‘traditional’ and non-market partnering exchanges, in order to identify core congruent issues, drivers and agents of change. It draws out a number of key themes to better understand why the construction industry has remained relatively unchanged; even though successive reports have tried to rectify the industry’s challenges. Acknowledging that there is no one clear definition, strategy or template for the effective implementation of partnering, findings from extant literature highlight eight dominant drivers deemed integral to augmenting project performance and profitability. So, whilst the construction industry invariably conducts its business with a smaller ratio of strategic partnerships than commonly believed, and accepting buyer dominance has predominantly remained, it is advocated that there is an exigent need to disentangle the project partnering initiative through some form of deterministic model. The case for this is presented through a relationship schema that maps the fabric, reliance and drivers for partnering success

    Dynamic real-time risk analytics of uncontrollable states in complex internet of things systems, cyber risk at the edge

    Get PDF
    The Internet of Things (IoT) triggers new types of cyber risks. Therefore, the integration of new IoT devices and services requires a self-assessment of IoT cyber security posture. By security posture this article refers to the cybersecurity strength of an organisation to predict, prevent and respond to cyberthreats. At present, there is a gap in the state of the art, because there are no self-assessment methods for quantifying IoT cyber risk posture. To address this gap, an empirical analysis is performed of 12 cyber risk assessment approaches. The results and the main findings from the analysis is presented as the current and a target risk state for IoT systems, followed by conclusions and recommendations on a transformation roadmap, describing how IoT systems can achieve the target state with a new goal-oriented dependency model. By target state, we refer to the cyber security target that matches the generic security requirements of an organisation. The research paper studies and adapts four alternatives for IoT risk assessment and identifies the goal-oriented dependency modelling as a dominant approach among the risk assessment models studied. The new goal-oriented dependency model in this article enables the assessment of uncontrollable risk states in complex IoT systems and can be used for a quantitative self-assessment of IoT cyber risk posture

    Sharing science, building bridges, and enhancing impact: Public-Private Partnerships in the CGIAR

    Get PDF
    "This study, which examines the role of public–private partnerships in international agricultural research, is intended to provide policymakers, research managers, and business decisionmakers with an understanding of how such partnerships operate and how they potentially contribute to food security and poverty reduction in developing countries. The study examines public–private partnerships in light of persistent market failure, institutional constraints, and systemic weaknesses, which impede the exchange of potentially pro-poor knowledge and technology. The study focuses on three key issues: whether public–private partnerships contribute to reducing the cost of research, whether they add value to research by facilitating innovation, and whether they enhance the impact of research on smallholders and other marginalized groups in developing-country agriculture. The study examines 75 projects undertaken by the research centers and programs of the Consultative Group on International Agricultural Research (CGIAR) in partnership with various types of private firms. Data and information were obtained through document analysis, semi-structured interviews with key informants, and an email survey of CGIAR centers. The resulting analysis provides a characterization of public–private partnerships in the CGIAR and describes the factors that contribute to their success. These finding are important to improving both public policy and organizational practices in the international agricultural research system." - from authors' abstract.Agricultural R&D, CGIAR, Innovation, Public-private partnerships,
