The authors propose a practical control method using neural networks and fuzzy control techniques, whereby neural networks estimate the target of fuzzy control. Neural networks estimate the transient state of a plant which has a nonlinear process such as refrigeration and filtering. Based on the estimation, a suitable control target pattern for fuzzy control is selected. This method has been applied to the tank level control problem of a solvent dewaxing plant. It is shown that the system can control the tank level effectively not only in the steady state but also in the transient state.< >

The SA'AR-5 Corvette Program is the first major warship construction to be entirely accomplished using a 3-dimensional, interference checked computer based design. This paper discusses the organization and approach used to create the design models which form the basis for interference checking as well as the source of extracted production data. The design or product model is the nucleus of the computer data base that defines the configuration of the entire ship. The data base includes geometry, weight, and material, as well as production control data. The ability of the computer to link such diverse information is the key to maintaining configuration control during the course of the design and construction. The ease with which formatted manufacturing data (both N.C. fabrication and installation) can be extracted enables the preparation of detailed packages containing the desired geometry as well as the associated material and sequencing data, thus assuring the producibility of the design. The SA'AR-5 design is CAD/CAM's state of the art in U.S. shipbuilding.

MEASURES OF EFFECTIVENESS AS APPLIED TO MAINTENANCE PRACTICES

引用

NAVAL ENGINEERS JOURNAL 1992年第4期104卷 101-102页

作者： JACOBS, KS ELFONT, M PROCACCINO, V Mark Elfont Ph.D:. is head of the Engineering Analysis Staff at the Naval Ship Systems Engineering Station (NAVSSES). At NAVSSES Dr. Elfont developed the Ships Machinery Analysis and Reporting Technique (SMART) System that utilizes direct access to the Ships 3-M database to calculate the fleet performance of HM&E systems. The SMART process is an automated approach to performance trending and offers the in-service engineers and life cycle managers cost effective information on the performance of equipments and systems in the actual fleet environment. Prior to coming to NAVSSES Dr. Elfont was at the Naval Air Development Center (NADC) for 18 years with most of his service as program manager for various avionic weapon system developments. Dr. Elfont also spent three years as the business manager of a private telecommunication firm. Vincent Procaccino:is the measures of effectiveness coordinator within the Performance and Business Indicators Section of the Equipment Assessment and Alteration Department Naval Ship System Engineering Station (NAVSSES). Mr. Procaccino is responsible for developing processes and techniques for determining the effectiveness of condition assessment efforts primarily the Assessment of Equipment Condition (AEC) program. NAVSSES is the Navy's in service engineering agent for HM&E equipment and is currently pursuing several programs which are in the process of evaluating condition assessment of HM&E systems. The efforts include continuous on-line monitors and expert system applications. Prior to arriving at NAVSSES in December 1988 Mr. Procaccino received a bachelor of science degree in mechanical engineering from Penn State University in August of 1987. He then worked as a project engineer for a small manufacturing firm until his arrival at NAVSSES.

Recent developments in surface ship maintenance strategies have been advanced on the promise of achieving reduced maintenance costs and improving the availability of shipboard systems. Included in the melange of proposed solutions are the Phased Maintenance Concept, Condition Based Maintenance, Expert System Diagnostics, as well as many other variations of these notions. As programs are initiated to evaluate prototype systems, or in some cases install production units, it is crucial that effective measurement procedures be instituted to determine to what extent the respective program goals and objectives are achieved. This paper explores various data sources that offer potential application to evaluation of advanced maintenance concept effectiveness. Also examined are data analysis and reporting techniques to clearly identify the benefits gained from those activities. The authors feel that it is important that the process of effectiveness evaluation, while remaining an objective process, become a part of the maintenance process itself. Maximum use of existing databases and in-place data collection procedures is advocated.

作者： HOPE, JP STORTZ, VE Jan Paul Hope a native of Northern Virginia received his bachelor of science degree in mechanical engineering from the University of Virginia in 1969. Upon graduation he began his career in the Department of the Navy with the Naval Ship Systems Command in the acquisition of patrol craft mine sweepers and submarine rescue ships. In January 1971 he transferred to the ship arrangements branch of the Naval Ship Engineering Center. He was selected for the long-term training program at George Washington University in 1974 and completed the program in February 1976 with the degree of master of engineering administration. While at the Naval Ship Engineering Center Mr. Hope was general arrangement task leader on the AO-177 CG-47 CSGN CSGN (VSTOL) CGN-9 (Aegis) and CGN-42 and he also assisted in the landmark Naval Sea Systems Command civilian professional community study. In 1978 he was selected as acting head of the damage control section and subsequently was selected as acting head of the surface ship hydrodynamic section. In February 1980 he was promoted to head of the surface combatant arrangements design section. Mr. Hope was selected for the first class of the NA VSEA commander's development program. While on the program he served in the DDGX combat systems engineering division and the DDGX project office of NA VSEA was the assistant director for ship design in the office of the Assistant Secretary of the Navy for shipbuilding and logistics and was the director of weight engineering and the director of systems engineering for the DDG-51 project in NA VSEA. Upon completion of the program Mr. Hope was assigned as the deputy director of the boiler engineering division to create a new division as a major fleet support initiative by NA VSEA. In June 1985 he joined the staff of the Assistant Secretary of the Navy for shipbuilding and logistics. Mr. Hope was presented the Department of the Navy meritorious civilian service medal in June 1983 for his service with the Office of the Assistant Secretary of the

This paper discusses the need and processes for designing warships to meet cost constraints and for managing warship acquisition programs during the design phase to assure effective adherence to production cost constraints by the design team. The resource control methodology used during the contract design of the Arleigh Burke class destroyer, DDG-51, is examined as a potential model for controlling the cost while maintaining the combat effectiveness of warships. The paper begins with a summary of the basic issue — the relationship among unit cost, unit capability, force level numbers, and force capability — showing recent trends in destroyer costs and force levels. This introduction also includes a discussion of the cost constraint for the DDG-51 in relation to historical trends and ship construction funding allocation. The resource control methodology used to reduce and control costs of the DDG-51 is discussed with a summary of the approach, key concepts and tools, chronology of key events, examples, and results achieved. A number of observations on this methodology are then made which are followed by comments on life cycle costs. The paper concludes with remarks on the future application of the resource control methodology and areas for further work to improve future resource control efforts.

The design of liquid cargo pumping systems for Navy auxiliary ships can benefit from application of modern commercial tanker practices which have evolved in recent years. Navy auxiliaries, which are outfitted for underway replenishment, traditionally have at least one pumproom and the designs are based upon a conventional pumproom type cargo system with horizontal or vertical centrifugal cargo pumps. Each cargo tank has a dedicated suction line leading to the cargo pumps. Latest commercial product tankers, especially lighters, which most closely resemble Navy auxiliaries in the manner in which they carry liquid cargos, have been built with in-tank deepwell or submersible cargo pumps, thereby eliminating the pump-room. The application of this type of pumping system reduces the size of the ship considerably, thereby resulting in reduction of required propulsive power and fuel consumption as well as a dramatic reduction in construction cost. The three most common pumping system designs are discussed in the paper, together with variations of each. The differences in systems are presented and their effect upon the design of an auxiliary ship is illustrated. The paper investigates the application of these alternate type cargo pumping systems (with dedicated pumps) to the design of a typical Navy auxiliary, indicating the effect upon ship size, weight, volume and power requirements as well as costs. Submersible pumps are compared to deepwell pumps with the advantages and disadvantages of each discussed. Experiences are cited.

The purpose of this paper is to explain the relationships of reliability to supportability in simple terms which should lead to an appreciation of the value of their application during the design process, as well as to the benefits to be derived during the ownership phase. Reliability and supportability are driven by resources; however, the former is constrained by the state-of-the-art at the upper end of the performance scale and may lead to unreasonable demands on maintenance and supply at the lower end. The first application of resources should be directed toward realization of optimum reliability. At a certain point though, the additional growth in reliability is no longer commensurate with the resources applied. It is then that the emphasis and resources should be shifted into the supportability arena, in order to maximize the operational availability of the system. Explicit examples are used to lead the reader to the conclusion that reliability analyses and the application of supportability criteria and tradeoffs are essential ingredients of any system design.

Chemical contamination as causes of electrical-insulation failure

引用

Electrical engineering 1945年第8期64卷 580-582页

作者： C. H. Braithwaite G. L. Moses Development insulation section a-c engineering department Westinghouse Electric and Manufacturing Company East Pittsburgh Pa.

Electrical-insulation failures were investigated and found to be due to chemical contamination with ionizable materials. Examples of such contamination are certain types of hand creams, soldering fluxes, and germicides in lubricating oils. Contamination mechanisms often involve operations which are otherwise insignificant in manufacturing processes. The effect of these materials on the electrical characteristics of the insulation is reported. The need for close correlation of industrial-hygiene manufacturing processes, insulation design, and quality control is emphasized.
