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

STANDARD HARDWARE ACQUISITION AND RELIABILITY program - CONCEPTS, BENEFITS, AND POTENTIAL

引用

NAVAL ENGINEERS JOURNAL 1989年第3期101卷 231-239页

作者： WEAVER, LW The author:is a program manager with Naval Weapons Support Center Crane Indiana. Mr. Weaver graduated from Indiana State University in 1969 where he received a B.S. degree with a mathematics major and a minor in physics. He began his career with the Naval Weapons Support Center in 1969 where he worked as a physicist and as an electronics engineer before entering various management positions. In the past ten years he has provided engineering and technical support to fleet ballistic missile guidance programs and to Navy standard computer and standard signal processor programs. He recently completed an assignment as manager of an electronics systems development division with responsibility for development of electronic control systems for fleet applications using standard electronic modules. Currently he is the program manager for the Standard Hardware Acquisition and Reliability Program (SHARP) managed through the Naval Sea Systems Command Sea-06. He is a member of the American Society of Naval Engineers and the Federal Managers Association.

The Standard Hardware Acquisition and Reliability program (SHARP) includes three major categories of hardware standards. They are Standard Electronic Modules (SEM), Standard Power Supplies (SPS), and Standard Electronic Enclosures (SES). SHARP responsibilities include development and testing of these standards and their integration into electronic systems. The purpose of SHARP is to reduce development, production, and logistics support costs of electronic systems; to improve system operational availability; and to shorten the system acquisition cycle. The basic concepts applied towards this purpose are: functional standardization; functional specification; a disciplined quality program; design flexibility; and emphasis on design for maintenance and repair. The paper describes the application of these concepts in the SHARP program and how they result in: — improved performance and supportability; — multisystem application of functional standards: — standard interfaces between system elements; — competitive procurement of hardware; — improved system readiness; — interchangeability of spares; — introduction of new technology into deployed systems; — improved testability; and — reduced cost to the Department of Defense (DoD). SHARP experience and benefits to the user are described, including specific applications of SHARP hardware in DoD systems and examples of multimillion dollar cost savings to these systems. The status of current SHARP initiatives and potential savings through broader application of SHARP in system developments are then discussed.

JCS Pub 1 defines interoperability as “The ability of systems, units or forces to provide services to and accept services from other systems, units or forces and to use the services so exchanged to enable them to operate effectively together.” With JCS Pub 1 as a foundation, interoperability of systems, units or forces can be factored into a set of components that can quantify interoperability. These components are: media, languages, standards, requirements, environment, procedures, and human factors. The concept described in this paper uses these components as an analysis tool to enable specific detailed analyses of the interoperability of BFC3 systems, units, or forces for the purpose of uncovering and resolving interoperability issues and problems in the U.S. Navy, Joint, and Allied arenas. Also, as a management tool, the components can help determine potential interoperability characteristics of future U.S. Navy BFC3 systems for compliance with battle force systems architectures. The approach selected for the quantification of interoperability was the development of a set of measures of performance (MOPs) and measures of effectiveness (MOEs). The MOPs/MOEs were integrated with a candidate set of components, which were used to partition the totality of interoperability into measurable entities. The methodology described employs basic truth table theory in conjunction with logic equations to evaluate the interoperability components in terms of MOPs that were aggregated to MOEs. It is believed that this concept, although elementary and based on fundamental principles, represents an operationally significant approach rather than a theoretical approach to the quantification of interoperability. The vehicle used as a means to measure the MOPs and MOEs was the Research Evaluation and systems Analysis (RESA) computer modeling and simulation capability at the Naval Ocean systems Center (NOSC), San Diego, Calif. Data for the measurements were collected during a Tactical I

The major objective of this paper is to describe a computer aided methodology for structural integration and analysis. Using the example of recent work in the installation of modular gun and vertical launch missile systems in warships, the reader is guided through a typical case of computer aided structural design and shock analysis, how the models are defined and tested, how the models are modified in order to be compatible with computer capacity, how structural elements are selected to simplify computations, and finally how the results of these operations are used to define the final product before construction and installation. With the maturation of the computer aided process as applied to the whole ship product, more attention must be focused on improving the individual elements of computer aided design (CAD), computer aided engineering (CAE) and computer aided manufacturing (CAM) and the integration of these processes and their products through computer integrated manufacturing (CIM). The application of the CAE techniques described herein to large maritime systems such as combatant, auxiliary and support, and commercial ships and to other large structures such as semisubmersible and fixed platforms is powerful and highly in demand. There is now a means to optimize large structural systems in terms of their discrete subsystems and components and harmonize the entire design while providing the proper design integrity at each successive level of detail.

NEW TECHNOLOGY IN OIL CONTENT MONITORS

引用

NAVAL ENGINEERS JOURNAL 1989年第2期101卷 48-55页

作者： NARDELLA, JA RAW, TT STOKES, GH John A. Nardella is the life-cycle manager for oil content monitor equipment for the Naval Sea Systems Command Washington D.C. He has an M.S. degree in chemical engineering from the Pennsylvania State University and is a licensed professional engineer in the Commonwealth of Virginia. Dr. Timothy T. Raw is the principal investigator responsible for the oil contamination monitor project. He has a doctorate in physical chemistry from Rensselear Polytechnical Institute and a B.A. in chemistry and computer science from Saint Louis University.

He has doctorate and M. S. degrees in physics from Princeton University and a B.A. from Colorado College. Previous to joining Geo-Centers Inc. he was a staff member in the Laser Fusion Program at Los Alamos National Laboratory.

International antipollution requirements have been legislated to regulate the oil content of bilge effluent from ships. In response to these standards, the U.S. Navy is currently in the process of installing pollution abatement equipment on all vessels. The equipment will consist of an oil-water separator in the bilge discharge line, followed by an oil content monitor which makes the final decision on whether or not the water is clean enough to be pumped overboard. The monitor is required to make a real-time measurement of oil concentration in the range 15 ± 5 to 100 ± 20 ppm for flow rates up to 50 gal/min. and possibly in the presence of interfering contaminants, such as rust. This paper presents the results of the current effort to develop a monitor which satisfies all of these requirements and is sufficiently rugged for fleet deployment. The monitor under development employs two fiber optic systems and a small microprocessor. The first optical system measures the concentration of particles in the flow as a function of their sizes, using small angle forward scattering. The second determines what percentage of the particles in the flow are oil, using large angle scattering. The microprocessor takes the data from the two optical systems and calculates the oil concentration in the flow. Since the particle size is measured by the monitor, no sample preparation is required and the monitor may be placed directly in the discharge line where it responds to changes in oil content in less than one second. In addition, this monitor can notify the operator of impending oil-water separator failure associated with passing large oil particles. A demonstration monitor consisting of the forward scattering unit has been successfully tested at the NavSea oil pollution abatement test facility at the Naval Ship systems engineering Station at Philadelphia. The monitor agrees well with chemical means of measuring oil content. Results of this comparison and laboratory test of a prototyp

ADISSA - ARCHITECTURAL DESIGN OF INFORMATION-systems BASED ON STRUCTURED ANALYSIS

引用

INFORMATION systems 1988年第2期13卷 193-210页

作者： SHOVAL, P 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

ADISSA is a methodology for Architectural Design of Information systems and Software, based on Structured Analysis. The architectural design includes: 1. (a) design of a tree-structured menu system, which interfaces between the users and the system—viewed as the “external architecture” of the system; and 2. (b) design of the transactions of the system, composed of various functions which are activated in response to user needs and various events in the universe of discourse—viewed as the “internal architecture” of the system. The menu tree and the transactions are tied up with the other major components of the system architecture: the inputs and outputs, and the database. ADISSA methodology is fully compatible and consistent with Structured Analysis, and therefore the stages of system analysis and design are integrated into one complete process.

A SURFACE NAVY VIBRATION program OVERVIEW - STANDARDIZATION AND STATE-OF-THE-ART

引用

NAVAL ENGINEERS JOURNAL 1988年第3期100卷 90-100页

作者： MARSHALL, BR The author is the material condition assessment (MCA) program manager at the Naval Ship Systems Engineering Station (NA VSSES). He received his BSEE from Drexel University in 1972 and worked for ten years in the vibration measurement and analysis field. His current position was established in 1982 to fill a NAVSSES need to provide coordinated support to NavSea and other Navy customers in the area of performance-based maintenance including the application of diagnostic techniques management of in-house MCA projects and interfacing with other government and private activities. His responsibilities include managing NAVSSES‘ efforts in the Systems and Equipment Maintenance Monitoring for Surface Ships (SEMMSS) Program and the CG-47 Class MCA Program presently being merged with SEMMSS. He is a member of the American Society of Naval Engineers and the Vibration Institute.

Ever scarcer maintenance dollars have resulted in changes to conventional maintenance strategies, notably extension of operating cycles and implementation of phased maintenance concepts. This trend has brought with it a need to accurately predict and define machinery repairs based on knowledge of system and component performance. In such an environment, Navy engineers (as well as those in the private sector) have increasingly turned to vibration analysis for condition assessment and diagnosis of wear-related degradation. In recent years, the surface Navy has acted to consolidate and coordinate the many separate and sometimes redundant efforts that have proliferated in the past by establishing a central NavSea office with responsibility for all diagnostics, including vibration analysis, and by appointing a technical agent to provide engineering support in this area. This paper presents a synopsis of the various surface Navy programs (the machinery vibration analysis [MVA] programs of the four surface ship repair planning agents, the ship's force programs under fleet sponsorship, and the vibration portion of a surface combatant monitoring program), delineates standardization accomplishments to date, and focuses on the issuance of a technical specification which regulates all aspects of instrumentation, data acquisition, and analysis. Details presented include the relationship of the latter two initiatives, and the establishment of a Navy owned and operated data base presently being implemented, with emphasis on the application of digital technology and telecommunications.

DATA MULTIPLEX SYSTEM (DMS) - ASPECTS OF FLEET INTRODUCTION

引用

NAVAL ENGINEERS JOURNAL 1988年第6期100卷 41-47页

作者： BLACKWELL, LM Luther M. Blackwell:is presently the Data Multiplex System (DMS) program manager in the Bridge Control Monitoring and Information Transfer Branch of the Naval Sea Systems Command (NavSea). He graduated from the University of Maryland in 1964 receiving his BS degree in electrical engineering. After graduating he was employed in the Bureau of Ships where he held project engineering assignments on various ships entertainment magnetic tape recording fiber optics computer mass memory and information transfer systems. He has also pursued graduate studies in engineering management at The George Washington University.

The Data Multiplex System (DMS) is a general-purpose information transfer system directed toward fulfilling the internal data intercommunication requirements of a variety of naval combatant ships and submarines in the 1990–2000 time frame. The need for a modern data transfer system of the size and capability of DMS has increased as various digital control systems throughout naval ships have adopted distributed processing architectures and reconfigurable control consoles, and as the quantity of remotely sensed and controlled equipment throughout the ship has increased manyfold over what it was in past designs. Instead of miles of unique cabling that must be specifically designed for each ship, DMS will meet information transfer needs with general-purpose multiplex cable that will be installed according to a standard plan that does not vary with changes to the ship's electronics suite. Perhaps the greatest impact of DMS will be the decoupling of ship subsystems from each other and from the ship. Standard multiplex interfaces will avoid the cost and delay of modifying subsystems to make them compatible. The ability to wire a new ship according to a standard multiplex cable plan, long before the ship subsystems are fully defined, will free both the ship and the subsystems to develop at their own pace, will allow compression of the development schedules, and will provide ships with more advanced subsystems. This paper describes the DMS system as it is currently being introduced into the fleet by the U.S. Navy. The results of its design and implementation in the DDG-51 and LHD-1 class ships are also presented.

A COMPUTER-MODEL FOR DAMAGE TOLERANCE ANALYSIS

引用

NAVAL ENGINEERS JOURNAL 1988年第5期100卷 59-68页

作者： FAIRHEAD, DL COHEN, SL Steven L. Cohen:heads the Survivability and Damage Control Office at the David Taylor Research Center. His career has addressed a wide range of technical and management responsibilities in the areas of HM&E systems design magnetic signatures system safety of surface ships and submarines shipboard energy conservation RDT&E (future fleet) life cycle costing survivability damage control CBR defense and management information systems. He has participated in all phases of the ship design process from conceptual design through ship construction operational evaluation and overhaul/modernization. Mr. Cohen is a graduate of Drexel University where he majored in electrical engineering and has more recently taken courses in the fields of systems engineering program management costing and microcomputer-based information and decision support systems.

A computer model is being developed by the David Taylor Research Center (DTRC) to analyze the tolerance of surface ship combat systems to combat-induced and self-inflicted damage. The work is being done in support of the Navy's hull, mechanical and electrical design effort to improve the survivability of surface ship combat systems. The DDG-51 Detailed Design Specifications (Section 072f) and the General Specifications for Ships of the U.S. Navy (1986 Section 072e) both require that damage tolerance analyses be performed. A damage tolerance analysis shows the effect of damage on vital auxiliary and electrical systems and relates these damage effects to the capability of the ship to continue performing its combat mission at a prescribed level. Designated the Computer Aided Design of Survivable Distributed systems (CADSDiS) model, DTRC's deterministic analytical tool consists of portable software to be used by personnel at the activity responsible for the ship design. The model's graphics electrical module is now operating on Digital Equipment Corporation VAX computers at several Navy and commercial activities. Because CADSDiS is highly interactive, it becomes an integral part of the design cycle; this is its major benefit. Thus, damage tolerance analysis information is available to personnel designing the ship within hours or days rather than weeks or months. This computer model will help ensure that the survivability principles of separation and redundancy are incorporated into ship design and are realized in the ship as built.
