    Capturing Corporate Philosophy: The Future of IT
    (Georgia Institute of Technology, 2000-02) Hale, Mark A. ; Daberkow, Debora Daniela ; DeLaurentis, Daniel A. ; Mavris, Dimitri N. ; Schrage, Daniel P. ; Craig, James I.
    Context is proposed as a mechanism for organizing Information Technology practices in the future through its role in interpretation. An enterprise organization model based on decision-flow is presented here that is applicable to a variety of domains. It contains elements that mark the information content with respect to a full consideration of its environment. These elements are, in order of increasing superiority, data, information, knowledge, judgement, and philosophy. There are four marked stages where contextual derivation occurs among these elements, including definition, refinement, improvement, and realization. Discovery occurs during the derivation of context and it is at this time that higher-level processes influence subordinate processes. For this reason, it is believed that corporate philosophy can be infused explicitly throughout enterprise practices. The resulting organizational model can be used by an enterprise to strategically allocate resources and maintain competitive advantage.

    DREAMS and IMAGE: A Model and Computer Implementation for Concurrent, Life-Cycle Design of Complex Systems
    (Georgia Institute of Technology, 1996-06) Hale, Mark A. ; Craig, James I. ; Mistree, Farrokh ; Schrage, Daniel P.
    Computing architectures are being assembled that extend concurrent engineering practices by providing more efficient execution and collaboration on distributed, heterogeneous computing networks. Built on the successes of initial architectures, requirements for a next-generation design computing infrastructure can be developed. These requirements concentrate on those needed by a designer in decision-making processes from product conception to recycling and can be categorized in two areas: design process and design information management. A designer both designs and executes design processes throughout design time to achieve better product and process capabilities while expending fewer resources. In order to accomplish this, information, or more appropriately design knowledge, needs to be adequately managed during product and process decomposition as well as recomposition. A foundation has been laid that captures these requirements in a design architecture called DREAMS (Developing Robust Engineering Analysis Models and Specifications). In addition, a computing infrastructure, called IMAGE (Intelligent Multidisciplinary Aircraft Generation Environment), is being developed that satisfies design requirements defined in DREAMS and incorporates enabling computational technologies.

    On the Development of a Computing Infrastructure that Facilitates IPPD from a Decision-Based Perspective
    (Georgia Institute of Technology, 1995-09) Hale, Mark A. ; Craig, James I. ; Mistree, Farrokh ; Schrage, Daniel P.
    Integrated Product and Process Development (IPPD) embodies the simultaneous application of both system and quality engineering methods throughout iterative design processes. The use of IPPD results in the time-conscious, cost-saving development of engineering systems. A computing infrastructure called IMAGE is designed to implement IPPD from a decision-based perspective. IMAGE has four components: designer activities, available assets, agent collaboration, and a computing architecture. IMAGE captures a designer's activities through a timeline partitioning scheme, problem formulation and solution, and comprehensive information management. To support these activities, IMAGE incorporates design resources through the use of agents. Agents are a critical computational enabling technology that provide accountable mechanisms for resource collaboration in an integrated computing environment.

    Implementing an IPPD Environment from a Decision-Based Design Perspective
    (Georgia Institute of Technology, 1995-05) Hale, Mark A. ; Schrage, Daniel P. ; Mistree, Farrokh ; Craig, James I.
    Integrated Product and Process Development (IPPD) embodies the simultaneous application of both system and quality engineering methods throughout an iterative design process. The use of IPPD results in the time-conscious, cost-saving development of engineering systems. Georgia Tech has proposed the development of an Integrated Design Engineering Simulator that will merge Integrated Product and Process Development with interdisciplinary analysis techniques and state-of-the-art computational technologies. To implement IPPD, a Decision-Based Design perspective is encapsulated in an approach that focuses on the role of the human designer in product development. The approach has two parts and is outlined in this paper. First, an architecture, called DREAMS, is being developed that facilitates design from a decision-based perspective. Second, a supporting computing infrastructure, called IMAGE, is being designed. The current status of development is given and future directions are outlined.
