    Defines a life-cycle that is tailorable to either commercial or aerospace system developments. The tailorability is accomplished by separately describing the product life-cycle, the acquisition cycles, and the technical steps used in performing the systems engineering. In addition, this life-cycle is based on the discovery of issues. The life-cycle described differs from both the waterfall model (... View full abstract»

    The concepts presented in this paper propose a pre-planned and integrated development process for large, complex, and possibly distributed systems-so-called “mega-systems”. A mega-system is partitioned into systems which are developed very independently but interoperate in an integrated manner to provide comprehensive functionality within an application domain, e.g. in the form of a so...

    Primarily stimulated through our work within the German Computer Societies Task Force on the Engineering of Computer-Based Systems (ECBS), we investigated the relationships between recent engineering process standardization efforts and current ECBS research. We showed that these have to be linked together more closely to achieve real progress in defining a sound basis for operating and managing th... View full abstract»

    Since the mid-1970s, several successful methods have been created for developing embedded computer systems. Most of them concentrate on techniques and tools for individual steps of the development process. Today, the success of large projects critically depends not only on the use of good individual techniques and tools, but also on a thorough understanding and successful management of the overall...

    Proposes a method that allows specifications to be described by as wide a range of people as possible. For that purpose, it is necessary to have support systems that enable the easy input of requirements and that provide complete specification generation mechanisms from the input requirements. In most cases, specialists describe specifications by applying common knowledge that is independent of in... View full abstract»

    Advances in microprocessor and network technology have led to the proliferation of complex systems with distributed processing and databases, internal communication systems, and heterogeneous components. The processing components can by themselves comprise a system, or they can be embedded in a physical system such as an automobile aircraft, or medical diagnostic system. Both the encompassing syst...

    The system concept is presented as a structure constituted from objects from the categories mission, operator, software and hardware. It is shown how Ada's semantics and syntax can be used in the pseudo language Odel to describe system structure and object behaviour, regardless of object category. Experience form 10 years of Ada-based methods work has led to an understanding of the evolutionary an... View full abstract»

    This paper is concerned with outlining a system theory for the engineering of computer-based systems (ECBS), and deducing policies for ECBS process management from it. We first review the scope and strategic state of a discipline of ECBS and motivate the need for an engineering theory. Next, we investigate the nature of conceptual work by emphasizing general modeling theory and concurrent modeling... View full abstract»

    Starting with the See-Saw and Problem Solving diagrams (H. Lawson, 1994), a useful definition of the major constituents of architecture for computer-based systems engineering, was made. This definition extends previous results. A first evaluation of the definition was based upon examining the properties of the British Aerospace DORIS approach as presented by H.R. Simpson (1994) View full abstract»

    The specification languages SDL and MSC are used for the development of soft real-time systems. We report on the development of two corresponding validation approaches: validation of designs by simulation and validation of implementations by conformance testing. The specification languages as well as these validation approaches are now being extended to apply to hard real-time systems. An account ... View full abstract»

    Modern computer-based systems (CBS) are complex multi-systems connected by complex computer-based communications. Each of the systems is in many cases, also a multicomputer system. The systems in a multisystem can be either geographically distributed or locally connected. Typical examples of CBS are; telephone and communications systems, management information systems (MIS), process control and ma... View full abstract»

    For any computer based system development to be successful, it is necessary that certain information is created and recorded. The ECBS information model described here represents the sum of the information which must be generated and/or collected during the life of any project to develop a computer based system. The basis for selecting the information was to adopt the attitude of a technical audit... View full abstract»

    Software development efforts are characterised by; project failures, runaway projects and integration and communication problems. Analysing why some projects finish on target while others lose track of their original objectives, constraints and milestones, can only be viewed as a long term investment.
