Poisson processes with failure intensity functions that are approximately constant are investigated. Maximum likelihood estimation procedures are used to estimate the failure intensity for a fixed level of approximation. The level of approximation is chosen through an adaptation of crossvalidation. Since model performance changes with time, the authors utilize a procedure that adaptively selects models over time. The predictive performance of such an adaptive procedure based on selection from among three nonparametric models is compared to that of the logarithmic Poisson and the exponential Poisson models for two software reliability data sets. © 1991 IEEE.

CLEER - AN AI-SYSTEM DEVELOPED TO ASSIST EQUIPMENT ARRANGEMENTS ON WARSHIPS

引用

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.

EVOLUTION OF A MODERN NAVAL STEERING SYSTEM

引用

NAVAL ENGINEERS JOURNAL 1987年第3期99卷 55-64页

作者： WAGNER, P VAIL, JA Paul Wagner:was born in Vancouver Canada in 1941 and after engineering studies at Ryerson Polytechnical Institute and the University of British Columbia received a diploma of mechanical technology and completed a Prakticant engineering course with Mannesmann in West Germany. On graduation he joined the firm of Wagner Engineering Ltd. in 1965 and after 10 years of design and manufacturing responsiblity was advanced to vice president of sales. Present responsibilities include management of research and development projects evaluation of new products and marketing. Mr. Wagner is a member of the Society of Naval Architects and Marine Engineers and the Canadian Institute of Marine Engineers. Jeannine A. Vail:is a graduate of the University of Pittsburgh and Wheeling College where she earned M. S. and B. S. degrees in mathematics. She is currently the president of Vail Research and Technology Corporation. Her experience includes 14 years in reliability maintainability and availability (RMA) engineering software development and cost analysis in the Naval Sea Systems Command the Naval Surface Weapons Center and industry. She developed RMA requirements and performed simulations on a wide variety of naval ships and underwater weapons. Ms. Vail is a member of ASNE IEEE and the Society of Reliability Engineers.

Ships' steering systems have progressed over the ages, driven by the need for more powerful and reliable systems. From simple mechanical devices thousands of years old to the latest electro-hydraulic systems, progress has been relatively slow but constant. Present systems tend to be the result of a series of modifications of older designs in response to a need for increased performance and reliability. This paper decribes the historical development leading to present designs and discusses a new approach which not only eliminates most problems inherent in present designs but also provides a more economical, more compact, and more cost effective solution as verified by detailed reliability and maintainability analysis.

COMBAT SYSTEM INDUSTRIAL-TESTING - MEASUREMENT OF SUCCESS

引用

NAVAL ENGINEERS JOURNAL 1986年第5期98卷 47-57页

作者： TRESSLER, DL HART, JB Dennis L. Tresseler is currently combat system test team leader for the combat systems test and evaluation branch of the Naval Sea Systems Command (SEA 61 × 11). Mr. Tresseler graduated in 1972 with a degree in mechanical engineering technology. He began his career at Newport News Shipbuilding in 1972 where he was a test director responsible for weapon system installation alignment and testing in CGN-36 thru 40 and CVN-68 and 69. In 1977 he came to the Washington area and worked for various contractors in technical and managerial positions before coming to NA VSEA in 1981. He is a member of the Naval Institute and his paper on “FF-1041 Class Modernization” has been accepted for publication in the Proceedings. J.B. Hart is currently the senior program manager combat systems for VSE Corporation headquartered in Alexandria Virginia. He is the program manager for VSE's master ordnance repair (MOR) team. His previous position was with COMPTEK Research Inc. Virginia Beach as senior combat systems engineer. Mr. Hart earned his BS degree from the University of New York in general engineering. He retired as chief ordnance control warrant officer after 22 years of service in 1982. While on active duty he served in various combat systems capacities since 1968 the most noteworthy of which were as ship's combat systems test officer/fire control officer on USS Belknap (CG-26) bringing her back into commission through major reconstruction and as combat system chief onboard USS Albany (CG-10) assisting in test and delivery of the first NTDS model 4.0 software program as well as numerous control systems updates both software and hardware.

This is an overview of the combat system test and certification (CST&C) program as a subset of the total ship test program (TSTP) for active fleet surface ships. The paper will discuss how the T&C program measures not only the suitability of repairs and modifications done during a ship's combat system industrial availability in a public or private yard period, but also the impact that successful program conduct has on the materiel effectiveness throughout a ship's operational cycle. The CST&C management organization and responsibilities, including NAVSEA's master ordnance repair program as well as combat system code 190's relationship to the CST&C program and the impact of pre- and post-industrial testing requirements on the actual conduct of industrial testing will be addressed.

Ship's propellers are currently measured by manual procedures using pitchometers, templates and gauges. This measurement process is extremely tedious, labor intensive and time consuming. In an effort to provide increased accuracy, repeatability and cost effectiveness in propeller manufacture, an automated propeller optical measurement system (APOMS) has been built which rapidly and automatically scans an entire ship's propeller using a 3-D vision sensor. This equipment is integrated with a propeller robotic automated templating system (PRATS) and the propeller optical finishing system (PROFS) which robotically template and grind the propeller to its final shape, using the APOMS-derived data for control feedback. The optical scanning and the final shape are both controlled by CAD/CAM data files describing the desired propeller shape. An automated propeller balancing system is incorporated into the PROFS equipment. The APOMS/PRATS/PROFS equipment is expected to provide lower propeller manufacturing costs.

th This volume presents the proceedings of the 6 IEEE International Workshop on IP Operations and Management (IPOM 2006), which was held as part of Manweek 2006 rd th in Dublin, Ireland from October 23 to 25 , 2006. In line with its reputation as one ofthe pre-eminent venues for the discussion and debate of advances of management of IP networks and services, the 2006 iteration of IPOM brought together an international audience of researchers and practitioners from both industry and academia. The overall theme of Manweek 2006 was “Autonomic Component and System Management”,with IPOM taking this to be the application of autonomic principles to the IP operations, administration, maintenance and provisioning (OAM&P) domain. IPOM 2006 is more relevant than ever to the emerging communications infrastr- ture that is increasingly focused on “convergence” of networks and services. Although arguably over-hyped, there is a fundamental truth to this convergence story, and this is based on the fact that the TCP/IP protocol suite (IPv4 and IPv6) has become the common denominator for a plethora of such converged services. One good example in the period between IPOM 2005 and IPOM 2006 has been the large scale deployment of consumer VoIP, linked to the success of Skype and alternatives including SIP-based approaches. In many countries VoIP is driving broadband deployment for SMEs where real costs savings can be accrued, especially for companies with remote staff in the ?eld.
