    Applications that can communicate with and control multiple medical devices have the potential to radically improve patient safety and the effectiveness of medical treatment. Medical device interoperability requires devices to have an open, standards-based interface that allows communication with any other device that implements the same interface. This will enable applications and functionality that can improve patient safety and outcomes. To build interoperable systems, we need to match up the capabilities of the medical devices with the needs of the application. An application that requires heart rate as an input and provides a control signal to an infusion pump requires a source of heart rate and a pump that will accept the control signal. We present means for devices to describe their capabilities and a methodology for automatically checking an application’s device requirements against the device capabilities. If such applications are going to be used for patient care, there needs to be convincing proof of their safety. The safety of a medical device is closely tied to its intended use and use environment. Medical device manufacturers create a hazard analysis of their device, where they explore the hazards associated with its intended use. We describe hazard analysis for interoperable devices and how to create system safety properties from these hazard analyses. The use environment of the application includes the application, connected devices, patient, and clinical workflow. The patient model is specific to each application and represents the patient’s response to treatment. We introduce Clinical Application Modeling Language (CAML), based on Extended Finite State Machines, and use model checking to test safety properties from the hazard analysis against the parallel composition of the application, patient model, clinical workflow, and the device models of connected devices

    Blockchain technology (BCT) is set to transform firms’ present ways of managing supply chains. This thesis explores how the efforts by firms to integrate BCT into their supply chain systems and activities, can enable certain supply chain capabilities and subsequently, improve supply chain performance. Using an abductive research approach, qualitative content analyses of 126 cases of firms’ efforts in BCT-based supply chain systems (BCT-SCS) across multiple industries are conducted to identify the BCT-enabled supply chain capabilities and their performance outcomes. Findings reveal that the present BCT-SCS efforts are mainly oriented towards improving the operational-level capabilities namely, information sharing and coordination capabilities rather than strategic-level capabilities namely, integration and collaboration capabilities. The predominant performance outcomes resulting from these capabilities along with the BCT-SCS are quality compliance and improvement, process improvement, flexibility, reduced cost, and reduced process time. However, the performance outcomes vary with industry type, based on the risks that the industry faces. Based on the study’s findings, an integrated framework of research propositions is presented to facilitate future empirical research

    Adoption of electronic health records (EHR) systems in nonfederal acute care hospitals has increased, with adoption rates across the United States reaching as high as 94%. Of the 330 plus acute care hospital EHR implementations in Texas, only 31% have completed attestation to Stage 2 of the meaningful use (MU) criteria. The purpose of this multiple case study was to explore strategies that hospital chief information officers (CIOs) used for the successful implementation of EHR. The target population consists of 3 hospitals CIOs from a multi-county region in North Central Texas who successfully implemented EHRs meeting Stage 2 MU criteria. The conceptual framework, for this research, was the technology acceptance model theory. The data were collected through semistructured interviews, member checking, review of the literature on the topic, and publicly available documents on the respective hospital websites. Using methodological triangulation of the data, 4 themes emerged from data analysis: EHR implementation strategies, overcoming resistance to technology acceptance, strategic alignment, and patient wellbeing. Participants identified implementation teams and informatics teams as a primary strategy for obtaining user engagement, ownership, and establishing a culture of acceptance to the technological changes. The application of the findings may contribute to social change by identifying the strategies hospital CIOs used for successful implementation of EHRs. Successful EHR implementation might provide positive social change by improving the quality of patient care, patient safety, security of personal health information, lowering health care cost, and improvements in the overall health of the general population

    Interoperability framework to enhance the DLT based systems integration with enterprise IT systems.

    Get PDF
    Distributed ledger technology (DLT) has generated tremendous interest due to its popular application to Bitcoin and other cryptocurrencies. Despite its enormous potential business benefits and even greater hype, DLT never attracted significant investment and its widespread implementation failed to occur. One of the most recognised reasons is the lack of an integration framework for integrating DLT-based systems with centralised or non-DLT information technology (IT) systems. This research endeavours to fill this gap by designing a DLT interoperability framework (DIF). This framework is based on the interoperability principles derived from integrated DLT-based solutions and modern organisations' integration needs and practices. DIF enables organisations to design interoperability architecture and integrated solutions for enterprise implementation. Based on the DIF, this research also developed and instantiated a Hyperledger Fabric DLT solution prototype (HDSP) on Amazon Web Services (AWS) for the manuka honey supply chain (MHSC) use case. The research utilised design science research (DSR) methodology to develop the DIF and HDSP. Iterative artefact evaluations were undertaken using formative (ex-ante), summative (ex-post), maturity model for enterprise interoperability (MMEI), IT professional evaluation, and artefact instantiation and demonstration techniques suggested in the DSR. The DIF, HDSP and their evaluation provide a pathway for organisations to design and implement integrated DLT-based solutions. The knowledge generated and utilised in this research provides a robust theoretical foundation for building and implementing such integrated solutions

    Blockchain-based Digital Twins:Research Trends, Issues, and Future Challenges

    Get PDF
    Industrial processes rely on sensory data for decision-making processes, risk assessment, and performance evaluation. Extracting actionable insights from the collected data calls for an infrastructure that can ensure the dissemination of trustworthy data. For the physical data to be trustworthy, it needs to be cross validated through multiple sensor sources with overlapping fields of view. Cross-validated data can then be stored on the blockchain, to maintain its integrity and trustworthiness. Once trustworthy data is recorded on the blockchain, product lifecycle events can be fed into data-driven systems for process monitoring, diagnostics, and optimized control. In this regard, digital twins (DTs) can be leveraged to draw intelligent conclusions from data by identifying the faults and recommending precautionary measures ahead of critical events. Empowering DTs with blockchain in industrial use cases targets key challenges of disparate data repositories, untrustworthy data dissemination, and the need for predictive maintenance. In this survey, while highlighting the key benefits of using blockchain-based DTs, we present a comprehensive review of the state-of-the-art research results for blockchain-based DTs. Based on the current research trends, we discuss a trustworthy blockchain-based DTs framework. We also highlight the role of artificial intelligence in blockchain-based DTs. Furthermore, we discuss the current and future research and deployment challenges of blockchain-supported DTs that require further investigation.</p

    A systematic methodology to analyse the performance and design configurations of business interoperability in cooperative industrial networks

    This thesis proposes a methodology for modelling business interoperability in a context of cooperative industrial networks. The purpose is to develop a methodology that enables the design of cooperative industrial network platforms that are able to deliver business interoperability and the analysis of its impact on the performance of these platforms. To achieve the proposed objective, two modelling tools have been employed: the Axiomatic Design Theory for the design of interoperable platforms; and Agent-Based Simulation for the analysis of the impact of business interoperability. The sequence of the application of the two modelling tools depends on the scenario under analysis, i.e. whether the cooperative industrial network platform exists or not. If the cooperative industrial network platform does not exist, the methodology suggests first the application of the Axiomatic Design Theory to design different configurations of interoperable cooperative industrial network platforms, and then the use of Agent-Based Simulation to analyse or predict the business interoperability and operational performance of the designed configurations. Otherwise, one should start by analysing the performance of the existing platform and based on the achieved results, decide whether it is necessary to redesign it or not. If the redesign is needed, simulation is once again used to predict the performance of the redesigned platform. To explain how those two modelling tools can be applied in practice, a theoretical modelling framework, a theoretical Axiomatic Design model and a theoretical Agent-Based Simulation model are proposed. To demonstrate the applicability of the proposed methodology and/or to validate the proposed theoretical models, a case study regarding a Portuguese Reverse Logistics cooperative network (Valorpneu network) and a case study regarding a Portuguese construction project (Dam Baixo Sabor network) are presented. The findings of the application of the proposed methodology to these two case studies suggest that indeed the Axiomatic Design Theory can effectively contribute in the design of interoperable cooperative industrial network platforms and that Agent-Based Simulation provides an effective set of tools for analysing the impact of business interoperability on the performance of those platforms. However, these conclusions cannot be generalised as only two case studies have been carried out. In terms of relevance to theory, this is the first time that the network effect is addressed in the analysis of the impact of business interoperability on the performance of networked companies and also the first time that a holistic approach is proposed to design interoperable cooperative industrial network platforms. Regarding the practical implications, the proposed methodology is intended to provide industrial managers a management tool that can guide them easily, and in practical and systematic way, in the design of configurations of interoperable cooperative industrial network platforms and/or in the analysis of the impact of business interoperability on the performance of their companies and the networks where their companies operate
