A methodology of perspective browsing to support concurrent design is presented using the concept of perspective and a new idea called hypergraph. Our approach uses the idea of browsing design for concurrent work, where a designer can proceed designing sessions using navigational operations. Browsing design uses the view as a trigger for obtaining information, which strongly supports the natural sequence of a designer's thought with the minimum interruption. The view is represented by the concept of perspective. We applied a model called PERMO, which encompasses the view and includes a navigational function using a new data structure called hypergraph. We developed a prototype system HYDRA based on the model to demonstrate the usefulness of our browsing methodology for design support system. The paper describes some examples of browsing design using HYDRA. © 1995 American Society of Mechanical Engineers (ASME). All rights reserved.

5.4.2 Mousetrap: A Concurrent engineering Simulation That Keeps Going…and going…and going

引用

INCOSE International Symposium 1995年第1期5卷 64-70页

作者： Zittel, Randy C. Department of Defense Systems Management College Systems Engineering Management Department 9820 Belvoir Road Fort BelvoirVA22060-5565 United States

The department of Defense systems management College uses the Stored Energy Ground Vehicle Simulation ("Mousetrap") to train future program managers in the application and power of concurrent engineering and the systems engineering process. The simulation has evolved over the past seven years into what we believe to be a world class concurrent engineering simulation, which additionally provides the military officers and DoD civilians a critically important industry perspective. Each student integrated product team performs the role of a defense contractor competing against other student "companies" in their quest for the single follow-on production contract to be awarded after completion of the acquisition development cycle and a government supervised competitive "run-off". They respond to a government request for proposal, negotiate a contract and spend time over 14 weeks developing a life cycle balanced system, expending and accounting for labor and actual government funds for materials. They must conduct three acquisition phase based technical design reviews presented to an integrated government program office, and subsequently build and field a competitive prototype. © 1995 The Authors.

IEEE International Conference on Fuzzy systems (FUZZ-IEEE)

作者： C. Nishio H. Shiizuka Graduate School of Systems Management University of Tsukuba Bunkyo Tokyo Japan Department of Electronic Engineering Kogakuin University Shinjuku Tokyo Japan

It is an important problem to obtain competitive market structures from brand-switching data. There are some approaches for obtaining the competitive market structures; for example, Hendry model, PRODEGY model Rao-Sabavala model, etc. However, these models have serious problems for ambiguity in the brand-switching data. In this paper, we propose a novel approach for obtaining competitive market structures from brand switching matrix by fuzzy structural modeling. The main idea of the paper is based on combining the fuzzy structural modeling and the brand-switching data. Application to the drink market structures indicates that the proposed approach has substantial validity.< >

Proceedings of the Pacific Rim TransTech Conference

作者： E.K. Morlok L.N. Spasovic UPS Foundation Professor of Transportation Department of Systems Engineering University of Pennsylvania Philadelphia PA USA School of Industrial Management Center for Transportation Studies and Research New Jersey Institute of Technology Newark NJ USA

The importance of reducing the cost of the highway portion (termed drayage) of intermodal rail-truck service in order to increase the competitiveness of such service with over-the-road trucking is discussed. Approaches to achieving this using modern information technology and various organizational changes are described, and estimates of the magnitude of potential cost savings are presented. Supporting public sector policies and actions are also described, with particular attention to ones that take advantage of the Intermodal Surface Transportation Efficiency Act (ISTEA) legislation and the Intelligent Transportation systems (ITS) program. The potential benefits in terms of reducing the break-even distance above which intermodal is preferred and expanding intermodal market share are discussed. The application of these ideas to port drayage is also discussed briefly.

We have developed a machine discovery system BONSAI which receives positive and negative examples as inputs and produces as a hypothesis a pair of a decision tree over regular patterns and an alphabet indexing. This system has succeeded in discovering reasonable knowledge on transmembrane domain sequences and signal peptide sequences by computer experiments. However, when several kinds of sequences are mixed in the data, it does not seem reasonable for a single BONSAI system to find a hypothesis of a reasonably small size with high accuracy. For this purpose, we have designed a system BONSAI Garden, in which several BONSAI's and a program called Gardener run over a network in parallel, to partition the data into some number of classes together with hypotheses explaining these classes accurately. © 1995, AAAI (***).

Stiff diagrams arc a multivariate method of analysis used to describe the chemical state of ground water. The use of Stiff diagrams to describe multiconstituent contamination sites, such as landfills, has distinct advantages over single constituent analyses. Problems associated with traditional Stiff diagram analyses, such as diagram attentuation, can be addressed by allowing the scale of the diagram to vary with the ionic strength of the analyzed sample. The use of these sliding scale Stiff diagrams reveals the chemical slate of the ground water over wide ranges of constituent concentrations and thus allows for sensitive and sophisticated depictions of complicated contamination sites in a fashion that is extremely difficult to replicate with single constituent analyses. This approach has possible applications for understanding and tracing the mixing and chemical changes in uncontaminated settings. Copyright © 1995, Wiley Blackwell. All rights reserved

This paper describes a computer program for generating finite element meshes for electron guns. Two new methods, the 'projection' and the 'mesh density function' methods, are used to generate the mesh. The new methods enable the mesh distribution to be set smoothly and changed easily, and also enable the mesh distribution to be adjusted according to parameters associated with the gun configuration or by feedback from the electric field calculation. The new program, which can handle a large variety of complicated electron gun structures, has been used in conjunction with the SOGUN program which has been developed by Zhu and Munro for electron gun simulation.

While the end of the Cold War minimized the threat of open ocean naval combat, new littoral warfare missions and threats such as tactical ballistic missiles have emerged. These threats and missions challenge the traditional military standard computing resources available to the Navy--a challenge that is increasingly difficult to meet in a cost effective manner. Furthermore, in recognition of the high cost of military standards, Secretary of Defense William Perry has directed that commercial standards be utilized wherever possible. As a consequence of this changing environment, the Aegis shipbuilding program has begun efforts to replace current military standard computing equipment with both higher performance commercial equipment and newer system architectures, i.e. distributed computing. As a part of this process, the Aegis program Office has collaborated with the Advanced Research Projects Agency (ARPA) to conduct a joint experiment on the feasibility of inserting a number of ARPA-developed distributed computing technologies into the Aegis combat system, The High Performance Distributed Computing program (HiPer-D) was created from this joint initiative. The overall objective of HiPer-D is to validate distributed computing for Navy shipboard combat system applications. This paper presents the results of the first HiPer-D demonstration of commercial computing technology as applied to the Aegis combat system.
