  • Quantifying the Influence of Component Failure Probability on Cascading Blackout Risk
    IEEE Transactions on Power Systems, 2018
    Co-Authors: Jianhui Wang
    Abstract:

    The risk of cascading blackouts greatly relies on failure probabilities of individual Components in power grids. To quantify how Component failure probability (CFP) influences blackout risk (BR), this paper proposes a sample-induced semianalytic approach to characterize the relationship between CFP and BR. To this end, we first give a Generic Component failure probability function (CoFPF) to describe CFP with varying parameters or forms. Then, the exact relationship between BR and CoFPFs is built on the abstract Markov-sequence model of cascading outages. Leveraging a set of samples generated by blackout simulations, we further establish a sample-induced semianalytic mapping between the unbiased estimation of BR and CoFPFs. Finally, we derive an efficient algorithm that can directly calculate the unbiased estimation of BR when the CoFPFs change. Since no additional simulations are required, the algorithm is computationally scalable and efficient. Numerical experiments well confirm the theory and the algorithm.

  • Development of a Web-services-based e-diagnostics framework
    2003 IEEE International Conference on Robotics and Automation (Cat. No.03CH37422), 2003
    Co-Authors: Min Hsiung Hung, Fan-tie Cheng, Sze-chie Yeh
    Abstract:

    In recent years, the emerging Web-services technology has provided a new and excellent solution to the data integration among heterogeneous systems. In this paper, a Web-services-based e-diagnostics framework (WSDF) is proposed. It can achieve the automation of diagnostic processes and diagnostics-information integration for semiconductor equipment. First, the system framework and the system Component model are designed. Then, the object-oriented analysis and design of system Components are accomplished. In particular, for the purpose of code reuse, several common functions, such as SOAP communication, UDDI registration, security mechanism, data exchange mechanism, and local database access, are built into a Generic Component, called Web-service agent. By inheriting the Web-service agent, other system Components can be constructed and have these common functions. In addition, a Generic equipment object model, a unified authentication-service mechanism, and a safe network connection are also designed in the framework. WSDF is intended to support the e-diagnostics functions defined by International SEMATECH. It is believed that WSDF can be applied to construct e-diagnostics systems for semiconductor manufacturing industry.

  • A development framework for semantically interoperable health information systems.
    International Journal of Medical Informatics, 2009
    Co-Authors: Diego M. López, Bernd Blobel
    Abstract:

    Abstract Background Semantic interoperability is a basic challenge to be met for new generations of distributed, communicating and co-operating health information systems (HIS) enabling shared care and e-Health. Analysis, design, implementation and maintenance of such systems and intrinsic architectures have to follow a unified development methodology. Methods The Generic Component Model (GCM) is used as a framework for modeling any system to evaluate and harmonize state of the art architecture development approaches and standards for health information systems as well as to derive a coherent architecture development framework for sustainable, semantically interoperable HIS and their Components. The proposed methodology is based on the Rational Unified Process (RUP), taking advantage of its flexibility to be configured for integrating other architectural approaches such as Service-Oriented Architecture (SOA), Model-Driven Architecture (MDA), ISO 10746, and HL7 Development Framework (HDF). Results Existing architectural approaches have been analyzed, compared and finally harmonized towards an architecture development framework for advanced health information systems. Conclusion Starting with the requirements for semantic interoperability derived from paradigm changes for health information systems, and supported in formal software process engineering methods, an appropriate development framework for semantically interoperable HIS has been provided. The usability of the framework has been exemplified in a public health scenario.

  • application of the Component paradigm for analysis and design of advanced health system architectures
    International Journal of Medical Informatics, 2000
    Co-Authors: Bernd Blobel
    Abstract:

    Based on the Component paradigm for software engineering as well as on a consideration of common middleware approaches for health information systems, a Generic Component model has been developed supporting analysis, design, implementation and harmonisation of such complex systems. Using methods like abstract automatons and the Unified Modelling Language (UML), it could be shown that such Components enable the modelling of real-world systems at different levels of abstractions and granularity, so reflecting different views on the same system in a Generic and consistent way. Therefore, not only programs and technologies could be modelled, but also business processes, organisational frameworks or security issues as done successfully within the framework of several European projects.
