The goal of autonomic computing is to reduce the configuration, operational, and maintenance costs of distributed applications by enabling them to self-manage, self-heal, and self-optimize. This paper provides two contributions to the Model-Driven Engineering (MDE) of autonomic computing systems using Enterprise Java Beans (EJBs). First, we describe the structure and functionality of an MDE tool that visually captures the design of EJB applications, their quality of service (QoS) requirements, and the adaptations applied to their EJBs. Second, the paper describes how MDE tools can be used to generate code to simulate adaptive systems for verification and plug EJBs into a Java component framework that provides runtime adaptation capabilities.  相似文献

Recent years have seen an increased recognition of the role of the human operator in both the development and use of military systems. Human Factors Integration (HFI), the structured management process for ensuring the capture and accommodation of human capabilities and limitations in design has, however, a mixed record of success within military system developments. This paper describes research conducted by the HFI Defence Technology Centre (HFI DTC) to identify and address the barriers to HFI through the development of processes, methods and tools. Future changes in the operational context and military doctrine are also discussed in terms of the likely adaptations to the HFI process.  相似文献

This paper describes the design and evaluation of a socio-technical design support system, the system reliability analyser (SRA). The tool is used to validate non-functional system requirements, such as system reliability. It employs a Bayesian belief network (BBN) model to assess system reliability (Pearl in Probabilistic reasoning in intelligent systems: networks of plausible information, 1988) based on a variety of high-level operational scenarios. The tool diagnoses problematic areas in future system models and assists in the identification of their causes. The evaluation of the tool demonstrated that it supported the task it was intended to do. The evaluation also identified usability problems in the current visualisations and illustrated their resolution.  相似文献

Recent research in software engineering has produced a number of techniques for structuring an understanding of systems. Many of these techniques are applicable to the design of embedded computer systems and produce designs whose structures are easily expressible in the ada language. This language is itself structured so that the design of a system can be expressed independently of its implementation. Thus ada can be a useful system design language (SDL) with these techniques. This paper describes the software design problem in the development of embedded computer systems. It shows how ada can be used as an SDL, as well as a system implementation language. The essential point is that as an SDL ada encourages designers to use recent theory to develop better structures for their systems, and its subsequent use to implement the systems preserves those structures in the product.  相似文献

This paper describes the development of a Bills of Material Processor (BOM) and shows how a relational data base system could greatly simplify the design and implementation of the processor on a computer. It describes the steps leading to the structuring of the data files based on data obtained from a manufacturing industry. Examples used in the discussion are real in that they refer to the actual development of a BOM processor using the RAPPORT relational data management system.  相似文献

Business-to-business e-contracting aims at automating the contracting process between companies. It improves the efficiency of the contracting process and enables the introduction of new business models that can be supported by companies. For the development of an e-contracting system, an architecture is required that describes the system components and the communication channels between them. This paper presents a reference architecture for the development of e-contracting systems. The architecture is designed on the basis of a requirement analysis of e-contracting systems. Established architectural principles are used in its design. The architecture can serve as a foundation in the analysis and design of concrete architectures of e-contracting systems. Furthermore, it can be used as a standardization model that facilitates system integration and communication of ideas. Its value for both software architects and business professionals makes it an important tool in the analysis and implementation of e-contracting systems.  相似文献

This paper describes ‘Goal Structuring Notation’ (GSN), a graphical notation that can be used to structure and present an argument justifying some aspect of system performance. The design of a fault-detecting processor pair is examined to determine the extent to which it is indeed ‘fault-detecting’. It is argued that for complex systems, difficulties with assessment arise not so much from a lack of analysis techniques, but from the need to integrate the results from many diverse analyses into a coherent and compelling argument. It is suggested that GSN provides a framework in which such an argument can be made.  相似文献

This paper describes the design of an RPC system for building object-oriented distributed software systems. The general requirements for such a system are to provide mechanisms for supporting inheritance, polymorphism, dynamic binding, and modular development in implementing distributed software systems. This paper presents the functionalities of this RPC system to support these general requirements. It also briefly describes the experiences with two previous versions of this system and how they led to the design of the final system. This system was implemented as a part of the programming environment of the Nexus distributed operating system. © 1998 John Wiley & Sons, Ltd.  相似文献

This paper describes a design process to support the development of a learning collaboratory, a distributed, computer-based, virtual space for learning and work. A learning collaboratory, as a distributed distance learning environment, offers great opportunities to expand the way people teach and learn and to broaden educational opportunities to an ever increasing range of learners. The challenge is to design distance learning technologies that engender meaningful learning experiences that take full advantage of the power of computer-mediated communication to support innovative learner-centered and collaborative interactions between students, teachers, subject experts, and resources. First, the paper describes the learning collaboratory design framework (LUCIDIFY), a design process that integrates methods and concepts from cognitive systems engineering, theories of learning and instruction, distributed computing, and computer-supported collaborative learning to guide the principled design of learning collaboratories. Next, the paper describes how LUCIDIFY was used in the design and implementation of the collaborative learning environment for operational systems (CLEOS), a learning collaboratory for teachers, students, and practitioners in the physical sciences. CLEOS features two virtual instrument tutorials, an asynchronous messaging system, a project-based design and management application, and a collaborative multi-user domain infrastructure.  相似文献

An agent-based workflow system for enterprise based on FIPA-OS framework   总被引:1,自引:0,他引:1  
The paper describes what we have learned from implementing a multi-agent architecture used to support enterprise notions and principles for intelligent systems design. In the last couple of years, agent-based management systems have been widely used to monitor and control business design processes. In this paper, multi-agent architecture is proposed and applied to the workflow management system in ASE1 (Advance Semiconductor Electronic) Inc., which is the world’s well-known largest provider of independent semiconductor for manufacturing services in assembly and test. The proposed FIPA-OS autonomous workflow management system uses a workflow co-ordination mechanism and an agent integration mechanism to enable the routine daily jobs error handle. Our vision for extending the FIPA-OS architectural elements to cover the development and implementation of generic web-Centric collaborative applications concludes the paper.  相似文献

Prototyping is not a new approach to computer-based information system development. It is just one technique among many used in system design. What might be new is for what purpose prototyping is used. The purpose could be to achieve a more user controlled system development and to give the future users a tool that will enable them to fully participate in not only the work with requirements specifications, but also in the actual systems design and organisational change. This paper describes a working model of an approach-the PROTEVS model-in which it is recommended that the future system users design their own prototype systems. The prototypes may act as both requirements specifications and solutions for actual change. This alternative approach aims to offer a basis for new ways of action for future users as participants in the design, evaluation, and change of a workplace. A suitable environment for the approach to act within is also described—a local design shop.  相似文献
