NAVAL ENGINEERS JOURNAL 1989年第3期101卷 127-137页

作者： ZHOU, HH SILVERMAN, BG SIMKOL, J Dr. H. Harry Zhou:is a research professor at the Institute for Artificial Intelligence of The George Washington University. Dr. Zhou received his master's degree and Ph.D. in computer science from Vanderbilt University in 1984 and 1987 respectively. He did his dissertation in the fields of artificial intelligence analogical reasoning and machine learning. His research interests include: classifier systems genetic algorithms learning by analogy inductive learning adaptive expert systems automated knowledge acquisition and adaption. He is also interested in data base design programming languages mental modeling and software engineering. Dr. Barry G. Silverman:is director of the Institute for Artificial Intelligence and a professor at the Engineering Administration Department of The George Washington University. He is also president of IntelliTek Inc. an AI consulting firm. Dr. Silverman received the B.S.E. M.S.E. and Ph.D. degrees from the University of Pennsylvania. He has been a principal developer of four generic AI products as well as eight AI applications. Since 1979 he has written over 100 papers and reports on these AI efforts. Joel Simkol:is a research scientist currently engaged in designing expert system architectures to support electronic warfare vulnerability analyses threat assessments shipboard topside antenna arrangements and C3countermeasures employment. Mr. Simkol's work in applying expert systems technology to electromagnetic interference and to spectrum management has generated increased interest and participation from all branches of government agencies.

This paper describes a modularized AI system being built to help improve electromagnetic compatibility (EMC) among shipboard topside equipment and their associated systems. CLEER is intended to act as an easy to use integrator of existing expert knowledge and pre-existing data bases and large scale analytical models. Due to these interfaces; to the need for portability of the software; and to artificial intelligence related design requirements (such as the need for spatial reasoning, expert data base management, model base management, track-based reasoning, and analogical (similar ship) reasoning) it was realized that traditional expert system shells would be inappropriate, although relatively off-the-shelf AI technology could be incorporated. In the same vein, the rapid prototyping approach to expert system design and knowledge engineering was not pursued in favor of a rigorous systems engineering methodology. The critical design decisions affecting CLEER's development are summarized in this paper along with lessons learned to date all in terms of “how,” “why,” and “when” specific features are being developed.

IFAC Proceedings Volumes 1988年第19期21卷 299-302页

作者： A.N. Georgieva P.A. Bayrov I.N. Ivanchev M.S. Gerasimova S.R. Simeonov Department of Programming and Computer Systems Application Higher Institute of Chem. Technology 1156 Sofia Bulgaria Department of Black Metallurgy Higher Institute of Chem Technology 1156 Sofia Bulgaria

An adaptive algorithm for LD converter steel refining control is presented. Avoiding the traditionally used balance approach, here a real-time process parameters estimation and control is applied. A Recursive Least Squares method is used and a minimum variance control strategy is realized. The original idea is that the converter steel making process| is considered as a continuous process which is sampled and one heat time is considered as one sample time. So, the process model parameters are adjusted after each heat and the algorithm adapts very fast to the technological conditions chanson. A distributed PS/XT computer two-leves control system is realized. Successful industrial results are obtained.

One of the most serious problems encountered in Naval steam plants following World War II was the unreliable performance of boiler and main feedpump pneumatic control systems. In addition to control component and system design deficiencies, these control systems suffered from inadequate methods to measure and adjust system alignment. This paper describes the development of a set of procedures for on-line alignment verification (OLV) of pneumatic main boiler and feedpump control systems. The procedures are designed for use by N avy control system technicians and, in addition to on-line alignment verification, provide guidance for troubleshooting and for performing system alignment. Procedure static checks measure steady state steaming performance and OLV procedure dynamic checks measure the ability of the boiler and control systems to respond to load changes. The paper describes typical control system characteristics that influence OLV procedure content and the supporting analysis that was used to establish alignment criteria ranges that satisfy both steady state and transient performance requirements. Also described is the alignment criteria tolerance analysis along with the steps involved in a typical OLV check procedure development. Descriptions of the various OLV checks, troubleshooting procedures and alignment procedures are provided. Typical shipboard implementation requirements are described and experience to date with the procedures is provided along with a status report on OLV procedure implementations.

NAVAL ENGINEERS JOURNAL 1980年第5期92卷 49-58页

作者： GALLAHUE, JS THE AUTHOR is the Department Manager of Combat Systems Engineering at Litton Industries. Data Systems Division. Prior to joining Litton Industries he was associated with UNIVAC. Since joining the Combat Systems Community in 1959. his assignments have included operational computer programming field engineering systems engineering equipment design proposal management test engineering. and programs management. In these varied roles he supported the NTDS R&D Program NTDS Service Test Program Interim Fleet Programming Center Pacific Anti-Submarine Warfare Ship Command and Control Systems SQS-26/NTDS/UBFCS Interface Design DD 963 Class LHA 1 Class. and the DDG 993 Class.

The required configuration management and the necessary control of the Surface Ship Combat System elements demand that they be considered as integrated and tested in accordance with an integrated test plan utilizing an integrated test organization. The sometimes used approach of implementing a combat system test program based upon the individual combat system elements being independent, has proven to be less than satisfactory. Then is no question that some of the early testing at the unit, subsystem, and subprogram levels can be planned and conducted independent of a specific “end-item” combat System. This paper addresses the planning and implementing of combat system test with the emphases being upon the integrated phase of test and primarily the lead ship of a class. Information is presented to facilitate planning and implementing a combat system test program including use of shore facilities and integrating these activities with shipboard activities; when to form the test organization and what types of expertise are required; what are the key technical management tools; the proofing of test documentation; the need for detailed “step-by-step” procedures and traceability of the specified requirements; how to assist Ships Force; planning and stat using the conduct of the tests; integrating computer program and special testing into the test program; and the significance of early decisions on administrative and contractual arrangements.

THE AN/UYK‐502(V) MICROcomputer

引用

Naval Engineers Journal 1979年第2期91卷 173-178页

作者： WILLIAMS, PAUL F. ANDERSON, JOHN M. Mr. Paul F. Williams:received his BS degree in Electrical Engineering from the University of Minnesota in December 1965. He joined SPERRY UNIVAC Defense Systems Division in January 1966 where he is now the Manager of the Computer Product Planning Group in the Marketing Department. He has been active in the development of new computer system architectures and new computer development including the AN/UYK-20 and AN/UYK-23. In addition he has worked with a number of Navies in the development of shipboard and landbased systems and has participated in the development of NATO Shipboard Standard Interfaces. Mr. John M. Anderson:received his BS degree in Electrical Engineering from the University of Washington in June 1969. He joined SPERRY UNIVAC in July 1970 where he is now a Senior Design Engineer in the Product Development Group. He is currently active in the development of the AN/UYK-520 Microcomputer and additionally has been active in the fields of digital logic design programming and computer testing.

The AN/UYK‐502 Microcomputer is a full‐scale, general‐purpose 16‐bit militarized computer designed to emmulate the AN/UYK‐20 and AN/AYK‐14, and to be implemented in a shipboard system employing distributed system architecture. Ship System Data Busses require microcomputers to be located near or within ship subsystems, with system interconnection being made through a common data bus. To implement this type of system architecture, a low cost, modular microcomputer capable of handling the bus “handshake” through a standard interface is required. The AN/UYK‐502(V) uses software common to minicomputers which allows different computer configurations to be implemented with bus architecture. The resulting system can then be maintained with a single set of support software programs thus significantly lowering system life cycle costs. The computer is offered in three physical packages: the Card Kit, Chassis Assembly, and Cabinet Assembly. Flexible options of the AN/UYK‐502(V) allow the user to tailor the system to the application needs. These options include the Central Processing Expansion Unit;main memory up to 2S6K (where K = 1024);memory parity;choice of 1 to 64 input/output (I/O) channels;parallel and/or serial I/O;and power supply selection. © 1979 American Society of Naval Engineers
