This paper describes the results of a study undertaken to determine the impact of fuel cell technology on the design and effectiveness of future naval surface combatants. The study involved the collection of data to characterize four different fuel cell technologies: proton exchange membrane, molten carbonate, phosphoric acid, and solid oxide fuel cells. This information was used to expand current computer models to develop specific fuel cell plants that met the power requirements for several applications on a nominal 5000 Lton destroyer and a nominal 2000 Lton corvette. Each of the fuel cell technologies was incorporated into several applications aboard the destroyer and the corvette. These applications included combinations of centralized and distributed ship service power, and propulsion power. In addition, the impact of fuel cell technology was determined for a ship service power backfit option aboard a DDG-51 class destroyer. The results of the impact on the ship designs were analyzed and a military effectiveness assessment was conducted to address such issues as the impact of fuel cells on mobility, survivability, affordability, and on the environment. The paper identifies which aspects of the fuel cell technologies have the greatest impact upon the ship designs and their operational costs. Recommendations are given for future technology development efforts required to make fuel cells suitable for Navy service.

Edward Deming cautions us to eliminate goals that create a ceiling of average performance. Yet we maintain that useful measurement systems can be developed that avoid performance ceilings and even encourage management team development. The process by which a measurement system is developed is as important as the measures themselves. We use a site application of a team building process as a defense of this statement. © 1992 IEEE.

USS Ingraham (FFG-61) is the prototype ship for NavSea's Advanced Technical information System (ATIS). ATIS is a digital technical library, which holds on optical disks the ship's 2,000 technical manuals and 73,000 drawing sheets. It contains a detailed ship's configuration index (derived from SCLSIS) to lead the user to the proper drawing or manual, and it replaces the ship's aperture cards and the second (library) copy of the technical manuals. ATIS, and the data standards established and tested through ATIS development, will be the technical library portion of micro-SNAP and SNAP III. It also forms an important part of NavSea's plans to utilize EDMICS data. This paper describes the goals and technical concepts behind the development of ATIS. Problems encountered, solutions developed, and lessons learned are detailed. Special attention was paid to the application of the computer Aided Acquisition and Logistic Support (CALS) standards, problems caused by conflicts and ambiguities in those standards, the standards. Original program goals are compared with actual operational experiences. Plans for future expansion are outlined, including applications of this technology in the availability planning and execution process. A comparison is developed among the various methods of optical imaging and their costs and benefits.

Quality and Reliability Engineering International 1992年第5期8卷 391-412页

作者： Halverson, Mark Ozdes, Demir Mark Halverson:received a BSEE from the University of Michigan in 1972 followed by an MS in Computer Information and Control System Engineering in 1973 also from the University of Michigan. Mr. Halverson has worked predominantly on military and aerospace design projects for such companies as Litton and Northrop. He is a specialist in inertial navigation and control systems. He has also worked with PLG Inc. as a risk analyst on various projects including commercial military and space applications. Since 1986 Mr. Halverson is an aerospace consultant working in Europe where he among other activities codeveloped the BRAT probabilistic risk analysis program. Demir Ozdes:received his BSEE from Purdue University in 1958 and his MSEE from the University of Arizona in 1963. He has over 35 years of experience in electronic design system engineering optimal control system design and analysis as well as in the design analysis and simulation of synergistic navigation systems. He has worked at Northrop Teledyne SPC TRW and Litton. Since 1984 he has been a private consultant in the aerospace field in Europe and is co-holder of patents as well as being a co-developer of the BRAT probabilistic risk analysis program.

This paper takes a broad overview of the reliability and safety engineering practice as it is commonly exercised in the aerospace and military industries today, especially with respect to complex electronic equipment which typically includes considerable software content. A general deficiency is noted with regard to the system-level approach to reliability. It would appear that the system-level reliability activities are given less attention than is needed, while excessive emphasis is placed on component micro- physics, component failure models, and various component-oriented analyses. systems-level reliability topics, which predominate in the equipment reliability which is actually observed, are sometimes ignored by reliability engineers. Methods and practical philosophies to re-establish a solid system engineering foundation for contemporary reliability practice, which have been developed through the authors' experience in the field, are presented. Finally, an example analysis is shown to illustrate the concepts.

A valuable technique during concept development is rapid prototyping of software for key design components. This approach is particularly useful when the optimum design approach is not readily apparent or several known alternatives need to be rapidly evaluated. A problem inherent in rapid prototyping is the lack of a "target system" with which to interface. Some alternatives are to develop test driver libraries, integrate the prototype with an existing working simulator, or build one for the specific problem. This paper presents a unique approach to concept development using rapid prototyping for concept development and scenario-based simulation for concept verification. The rapid prototyping environment, derived from artificial intelligence technology, is based on a blackboard architecture. The rapid prototype simulation capability is provided through an object-oriented modeling environment. It is shown how both simulation and blackboard technologies are used collectively to rapidly gain insight into a tenacious problem. A specific example will be discussed where this approach was used to evolve the logic of a mission controller for an autonomous underwater vehicle.

information AND SOFTWARE TECHNOLOGY 1990年第5期32卷 357-369页

作者： SHOVAL, P MANOR, O Computer and Information Systems Program Department of Industrial Engineering and Management Ben-Gurion University of the Negev P.O. Box 653 Beer Sheva 84105 Israel.

In software engineering, computer-aided software engineering tools are used to implement the methodologies of development in an automated or semiautomated environment. A number of tools are presented that were developed to support ADISSA (Architectural Design of information systems Based on Structure Analysis), a comprehensive methodology that treats analysis, design, and data modeling aspects as stages of a continuous process. This methodology covers in a unified way the stages of functional analysis, transactions (process) design, interface design, database schema design, input-output design, and structured prototyping. The personal computer-based ADISSA-supporting tools provide an automated environment that enables the analysts or designers, who work according to the methodology, to draw hierarchical dataflow diagrams and check their correctness, to design the transactions of the systems, the interface - a menu-tree - and the database schema, and to maintain an integrated data dictionary.

The Nick Summer Experiment was an empirical study undertaken to explore and increase the understanding of the use of prototype meeting support technology by software design teams working on high-level design problems. Three teams of designers (seven MCC researchers per team) were observed and videotaped while participating in 27 one-hour, face-to-face design meetings in both the electronic meeting room and in a conventional meeting room. The Nick support technologies explicitly aided the affective social meeting structures, as well as the rational task-oriented processes. Analysis of the experimental data revealed some gains in meeting effectiveness and quality from use of the Nick meeting support technologies. The 'subchannel' (messaging facility on the electronic workstations) emerged as a potentially effective way for participants to attain more equality and to influence the direction of the meetings. The electronic blackboard helped to increase group focus and attention on completing the task. [ABSTRACT FROM AUTHOR]

Electronic meeting systems (EMS) have been introduced inside IBM in a cooperative effort between IBM and the University of Arizona to address the demands of an increasingly competitive and turbulent business environment. This paper presents and integrates the results of two field studies intended to evaluate the implications of electronic meeting system use at IBM. The first study focused on session process and outcome effectiveness, efficiency, and user satisfaction at a single IBM site. The second study collected data on EMS tool use and facilitation approach within sessions at four IBM sites. The two studies are complementary in reflecting the impact of computer-based support on group process and outcome. Effectiveness, efficiency, and user satisfaction are generally enhanced independent of type of activity supported or perspective, e.g., participant, facilitator, or session initiator. Facilitation training is a critical requirement for successful integration and application of electronic meeting system software and procedures in the group processes this paper addresses.

The U.S. Navy relies heavily on advanced technology to carry out its missions. As a consequence, today's sailors are spending increasing amounts of time maintaining and repairing complex systems and equipment. In performing these duties, sailors depend on supporting technical documentation. As the complexity of systems and equipment grow, the volume and complexity of this technical documentation also increases. As a result, technical information, one of the Navy's critical resources, is simultaneously becoming more vital and more difficult to use. The Navy is meeting this challenge by exploring innovative approaches to the management of technical documentation. One example is the Paperless Ship Initiative, which employs optical disk technology as the primary means for document storage. Optical disks can store large volumes of technical information in a small space. One way to take advantage of this auto mated access is to make technical information more readily accessible and easier to use. As an example, a technical manual can be organized on an optical disk into discrete segments of text and indexed for fast retrieval by section, subsection, or paragraph. Furthermore, mechanisms can be developed which allow computer-supported links between logically related segments of the text. This style of interface allows a user to interact directly with the textual passages and to establish new organizational and referential links between them. This style of interface falls under the general category of hypertext (also known as linked text ). The combination of optical disk storage and hypertext offers new possibilities for improving access to large volumes of technical documentation while maintaining all of the advantages of traditional paper-based documentation. This paper begins with a discussion of the need for better technical documentation support. Alternatives that can fulfill this need are reviewed and the role of hypertext is described. The paper illustrates a sample
