At present he is head of the Auxiliary Equipment Division Naval Sea Systems Command where for the past six years he has been responsible for the design operation maintenance and life cycle support for the majority of the U.S. Navy's shipboard auxiliary equipment. He has been a member of U.S. and international committees on standardization and has been a delegate representing the U.S. at several meetings throughout the world.

This paper presents improvements in logistics support of hull, mechanical, and electrical (HM&E) components through standardization to the piece part level. The process of component standardization is outlined and compared with traditional HM&E acquisition approaches. The impact of standardization on logistics support is presented with case examples cited to graphically demonstrate how logistics improvements are derived. The paper also presents standardization costs and benefit analyses. A compelling case for increased HM&E standardization efforts is made from a logistics improvement perspective.

Prior to this assignment he was assistant engineering officer on the USCGCUte.His other duty tours included engineering assignments on theCape Currenta 95-foot patrol boat on the USCGCUnimak a 311-foot cutter CG Loran Station Upolo Point Hawaii and CG Station Sabine Pass Texas. CWO McCollum was responsible for modifying and repairing the SESs and contributed many unique problem solving ideas which resulted in much improved operation of the Coast Guard Surface Effect Ship Division. Benton H. Schaub:is a senior engineer with Maritime Dynamics Inc. He has a bachelor of science degree in naval architecture and marine engineering from the Massachusetts Institute of Technology. Mr. Schaub has fifteen years of experience working as a test engineer project engineer and design engineer on advanced marine vehicle projects and is a recognized authority in the areas of hull structure seal system and machinery design for surface effect ships. He has participated in virtually every USN SES design development and test evaluation program including: XR-5 XR-10 SES-100A SES-100A1 and the SES-200. He is currently responsible for performing detailed design and analysis in support of the seal system for the Germa

During the early 1980s the United States Coast Guard took delivery of three surface effect ships (SES) from Bell Halter, Inc. These 136-ton, 30-knot plus, aluminum hulled cutters were to be used primarily for drug interdiction in the southeastern United States. By early 1985, however, the full load weight of these cutters had grown to 150 long tons, and their top speed had dropped to below 23 knots in calm water. By mid-1985, operation of all three SESs was suspended to prevent possible catastrophic failure of their main engines. At this point, the USCG joined ranks with Textron Marine systems (then Bell Aerospace), and Detroit Diesel to analyze what had gone wrong, and to propose solutions to the problems encountered. From that beginning, the performance of the Coast Guard's SESs has steadily and dramatically improved until at present all three cutters are able to exceed their original performance specifications. This paper discusses the problems experienced with the SESs, including engine overloading, vibration, ride quality, seal wear, poor lift system performance, and metal cracking, along with the corrective actions taken to solve them. The cooperation between government and private industry, which made this dramatic turn-around in performance possible, is also explored. Lessons learned about SES technology are viewed in relation to the general experience of the Coast Guard with other types of high performance hull forms.

engineering processes, for the integration of topside electromagnetic environment and EM subsystems performance engineering into the mainstream of surface ship engineering, are presented and discussed in this paper. The engineering procedures and tasks pertaining to ship EM systems engineering must be tailored to the several stages of the life cycle, but all contain a core of activities covering performance-based EM suite selection and topside arrangement design, which is based on EM environment and performance vs. requirements analysis. These core activities are presented and discussed as they apply to all life cycle design stages. Several recent fleet EMI problems are briefly discussed for the insight they provide relative to the EM portions of the current design process, and conclusions regarding how the proposed procedures address current deficiencies are included.

Annals of Operations Research 1986年第1-4期5卷 517-538页

作者： Zenios, S.A. Mulvey, J.M. Engineering-Management Systems Program Civil Engineering Department Princeton University Princeton 08544 New Jersey United States

Gauss-Seidel type relaxation techniques are applied in the context of strictly convex pure networks with separable cost functions. The algorithm is an extension of the Bertsekas-Tseng approach for solving the linear network problem and its dual as a pair of monotropic programming problems. The method is extended to cover the class of generalized network problems. Alternative internal tactics for the dual problem are examined. Computational experiments -aimed at the improved efficiency of the algorithm - are presented. © 1986 J.C. Baltzer A.G., Scientific Publishing Company.

He also holds an MS in engineering management from Drexel University (1980). He is currently the section head of the newly formed Cargo/ Weapons Handling Systems Alteration Installation Team at the Naval Ship Systems Engineering Station (NAVSSES). Prior to that he was the section head of the Aircraft Carrier Weapons Elevator and SASS Systems Section at NA VSSES. It was in this section that Mr. Compton was responsible for NA VSSES efforts in the standard cargo/weapons elevator RDT&E program. He has been involved with this program since the beginning and is responsible for the development of the Standard Cargo/Weapons Elevator Land Based Engineering Site. He is a member of ASNE and has been with NA VSSES since 1972. He has been working with cargo/weapons elevators since 1977. Theodore C. Anderer PE is a senior project engineer in the Hull and Deck Machinery Department of the Naval Ship Systems Engineering Station Philadelphia Pennsylvania. He holds a BSME degree from Drexel University and has continued education toward an MBA. Mr. Anderer is a registered professional engineer. He has over 25 years experience in the design of medium and heavy equipment. During the past 10 years Mr. Anderer has been in project management positions on multimillion dollar naval and industrial projects. He held a key position in the development of the first coal-fired ship built in 45 years. Currently Mr. Anderer is the leader of the RDT&E team at NA VSSES tasked with the development of standard cargo/weapons elevator specifications and the design and construction of a full-scale 6-deck elevator. Frederick A. Heinzeis presently employed by Advanced Marine Enterprises Inc. at the Cherry Hill N.J. office as a program manager/senior engineer. His work involves designs and specifications for standard cargo/weapons elevator components and the NA VSSES Land Based Engineering Site under contract to NA VSSES. Mr. Heinze holds a BS degree in mechanical

In 1980, at the Ship systems Technical Symposium in Cherry Hill, New Jersey, a paper was presented entitled “Reliability of Shipboard Elevators — Is There Hope for Improvement?” It painted a bleak picture of elevators and their future. The history of Navy cargo/weapons elevator installations does reveal a wide variety of equipment sizes and con figurations developed by numerous vendors working to different performance specifications for each contract. The result has been poor reliability, a proliferation of spare parts requirements, and logistic and maintenance nightmares. To correct this, NAVSEA has initiated various efforts, including a program to develop and test improved, standardized designs. The improvements expected by that program include standard capacities and speeds, lightweight construction and easy removability for maintenance. This is being accomplished through standard drawings and detailed, as opposed to performance, specifications. But the key to the success of this effort is to design and test for reliability, maintainability and safety. This is being accomplished by following NAVSEA Quality Assurance Plan 200, which specifies failure mode, criticality, stress, worst case and sneak circuit analyses. New equipment will be tested and evaluated at the new land based engineering site (LBES) at the Naval Ship systems engineering Station (NAVSSES), Philadelphia, Pennsylvania. This site has been designed to test elevator systems and components and simulate shipboard conditions including temperature and humidity. Initially, equipment intended for the new AOE-6 and AE-36 classes will be tested. The site will also be able to test cargo and weapons elevator doors and hatches in an aircraft carrier configuration. The site includes a standard hydraulic power unit (HPU) to operate flush deck and in-trunk hatches and different door types. This paper describes the philosophy and methods for the overall standard elevator RDT&E effort and how it will improve the rel

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.
