    There are many ways in which we can describe systems engineering. It can be described according to structure, function, and purpose. It may be described in terms of efforts needed at the level of systems management, systems methodology, and systems engineering methods and tools. We can speak of systems engineering organizations in terms of their organizational management facets, in terms of their ... View full abstract»

    Domain modeling is believed to be a key factor in developing an economical and scalable means for constructing families of related software systems. In this paper, we review the current state of domain modeling, and present some of our work on the ADAGE (Avionics Domain Application Generation Environment) project, an integrated environment that relies heavily on domain models for generating real-t...

    Systems analysis, or as it is increasingly known as today, requirements engineering, is a time-consuming, expensive, but critical phase in software (and system) development. At the same time, demand for software continues to exceed supply, and software reuse is now high on the agenda of the computing industry. The higher up the software development lifecycle that reuse takes place, the greater the... View full abstract»

    Selecting a set of metrics to evaluate a system design is a difficult but important task. Determining if a project is within the realm of the possible for a company before the task is undertaken helps to reduce risk and increase the chances of success. We have selected a set of metrics and applied them to 17 case studies. These are all successful design efforts, but vary in the difficulty of the d... View full abstract»

    The system design problem describes the process used to translating the need or requirements for a system into an actual design. It requires selecting components from a given set and matching the interfaces between them. Those that can be connected to meet the top-level system's input and output requirements are tested to see how well they meet the system's performance and cost goals. We prove tha...

  • Sensitivity analysis by design of experiments

    Publication Year: 1995, Page(s):58 - 65
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (614 KB)

    Experimental design is offered as an empirical method of sensitivity analysis. In particular, the use of uncontrollable factors and second-order effect estimates are suggested to ensure robustness of the system to parametric uncertainty. An augmentation to Yates' (1937) algorithm for 3/sup k/ factorial designs is described. View full abstract»

    Object-oriented methodology has developed to the point where it has the potential for being a powerful tool in the arsenal of the systems engineer. This paper suggests that the time is ripe for systems engineers to assimilate the method. Such assimilation will require modifications in the method to make it generalizable outside the software design environment. This paper presents the lessons learn... View full abstract»

    A study was undertaken to assess the impact of employing fuzzy technologies in areas of complex weapon system design. The technology was examined for use in a life-cycle cost exercise with the objective of providing a foundation from which to make service life assessments and recommendations on future weapon systems. The issues associated with this problem can be highly subjective and often exhibi... View full abstract»

    The importance of a clean system architecture in the context of computer based systems increases significantly with the ever higher level of complexity these systems exhibit. As a consequence, the identification of useful architectural concepts and their description in architecture models has become an important concern for software engineering practitioners and researchers. We look at system arch... View full abstract»

    The paper considers some of the problems of developing large computer based systems and argues that many of these problems can be eased by adopting a good architecture. The term architecture is frequently used in the context of computer based system (CBS) development, but there are almost as many definitions of it as there are uses. Therefore a definition is derived from its use in English and the... View full abstract»

    Systems engineers and software engineers work together in the development of modern complex systems. The two engineering cultures, the concepts, and the best practices have developed independently over four decades. Notations and naming conventions for the same things are often different. Yet the efficient exchange of engineering information and wisdom between the two professions is important to t... View full abstract»

    Software that is used to control critical systems is frequently tasked to ensure the safe operation of the system under its control. The paper suggests the use of fault tree analysis with an external interaction model as part of the software requirements specification and analysis phase for the development of such systems. After a brief review of the model, the general fault tree analysis techniqu... View full abstract»

    Superior system level development of computer based systems (CBSs) demands a rigorous approach that authoritatively defines an integrated design solution before proceeding very far with customary pro forma documentation. Such an approach would early on address issues like overall concurrency logic, real time performance, and system management overhead in a unified and exacting manner. The prototyp...

    The development of computer application systems using traditional data processing methods has been labor intensive, error prone, slow and extremely costly. Information engineering can solve these problems. It addresses strategic planning as well as analysis and design. It is mainly data driven, not procedure driven. In an information engineering approach, however, the data dictionary manages only ... View full abstract»

    Computer based systems (CBS) are often expected to be able to handle a complex system environment. In addition, the CBS itself generally exhibits an inherent complexity. This induces the necessity to search for adequate systems design and development processes which allow us to deal with both sources of complexity. The thesis discussed, suggests that the systems to develop, as well as the process ... View full abstract»

    For several years we have been working on an architecture for modelling and implementing autonomous agents. This work has been recently extended in two directions: evaluating the benefits of the architecture in a real-world setting in terms of ease of design, rapid prototyping, dynamic resource management, and studying methods for formal analysis of the reactive subsystem based on the composition ...

    This paper discusses concept and techniques supporting modeling, planning and execution of design activities in distributed design environments. The task of planning, executing, and supervising the design environments has become so complex that in itself requires advanced computer support facilities. We propose concepts which integrate design process models, knowledge representation schemes, and c... View full abstract»

    This paper argues that, like for any engineering discipline, experience and heuristics of Engineering of Computer Based Systems need to be grounded in a practical theory. On top of such a theory, a systems engineering approach has to be defined that allows the professional practice of the discipline and the safeguarding of the entire life cycle of all its artifacts. Such a systematization of a dis... View full abstract»

    Product model sharing is a crucial technical factor in the integrated engineering process, where dissimilar computer-based tools interact with a common data model. Model sharing, and also genuine data transfer between design tools, is possible only under strict conditions. It is important to describe these conditions explicitly in order to predict and to test that transfer transactions proceed cor... View full abstract»

    This paper describes a method for modeling complex, closely intermeshed engineering processes. The FACETS method (referring to the numerous facets of such processes) is a way of describing all the essential features of such processes using transparent, condensed and easily understood representations. We call these representations "views" because they permit an individual, situation-oriented and in... View full abstract»
