25th International computer m.asurem.nt Group Conference, Cm. 1999

作者： Gibson, Lieutenant Colonel Tim.m.ller, Ethan L. Camp H. M. Smith HI96861 United States Department of Computer Science and Electrical Engineering University of Maryland-Baltimore County BaltimoreMD21250 United States

As m.re com.uting centers collect files to use in data-m.ning or data-m.rts, m.naging long-term.storage space becom.s m.re im.ortant. We describe a new way to m.re accurately predict which files will be used in the future. This new m.thod is an order-of-m.gnitude m.re accurate than any current technique. Fifty to eighty percent of all user files can be com.ressed or m.ved to tertiary storage with little im.act on the user perceived perform.nce. This paper supports these conclusions with an analysis of long-term.(5-8 m.nths) data collected on different types of com.uting environm.nts. © 1999 25th International computer m.asurem.nt Group Conference, Cm. 1999.

Advances in aircraft carrier life cycle cost analysis for acquisition and ownership decision-m.king

引用

NAVAL ENGINEERS JOURNAL 2000年第3期112卷 97-110页

作者： Chewning, Im.m.retto, SJ Irvin M. Chewning:is currently the Director of the Aircraft Carrier Cost Estimating and Industrial Analysis Group of the Naval Sea Systems Command. Over the past four years Mr. Chewning has guided the cost analysis effort for the new CVNX class aircraft carrier through a three-part analysis of alternatives and is currently steering it towards Milestone I in June of 2000. In 1999 the CVNX cost analysis team was presented the NAVSEA Association of Scientists and Engineers “outstanding team achievement” award for its work on the CVNX analysis of alternatives. Mr. Chewning's professional career includes over 16 years as an employee of Newport News Shipbuilding as a Pipe Fitter Piping Systems Designer Piping Systems Engineer and Cost Engineer. He has worked at the Naval Sea Systems Command since 1980 as a Senior Cost Analyst Branch Head and Deputy Division Director of the Cost Estimating and Analysis Division. He has preformed cost analysis work for virtually all USN combatant programs including submarines cruisers destroyers frigates and aircraft carriers. He also performed the cost analysis work for the OSD evaluation of the Israeli Naval Modernization Program in the 1980's. Mr. Chewning is also Chairman of the NATO Specialist Team on Ship Costing a subgroup of the NATO Naval Group Six on Ship Design. Under his leadership two Allied Naval Engineering Publications have been completed in the 1990's: ANEP-41 on Ship Costing and ANEP-49 on Ways to Reduce Costs of Ships. In 1999 the NATO Specialist Team on Ship Costing completed a paper titled “Manpower Reduction and the Use of Commercial Standards and Practices to Reduce Costs of Ships.” The result of this work will be incorporated in a future revision of the aforementioned ANEFs. Mr. Chewning is a graduate of North Carolina State University with a Bachelor of Science in Mechanical Engineering. Mr. Chewning has also completed courses at the University of Virginia and Christopher Newport University Mr. Chewning is a graduate of the Program Management College

The U.S. Navy recently conducted an analysis of alternatives (AOA) to set the stage for determ.ning the characteristics and acquisition strategy for its next generation aircraft carrier. The platform.design selected is expected to be in service throughout the 21st century. The param.ters under consideration for change in the new carrier design lie in the areas of propulsion and electric power generation, aviation, survivability, service life, and total ownership cost (TOC) reduction. The issue of affordability is param.unt This paper focuses on the need for the program.m.nagem.nt office and its supporting cost analysis staff to understand the life cycle cost (LCC) of the existing and proposed future aircraft carriers and to then translate these LCC's into m.aningful inform.tion for cost-conscious decision m.king. The challenge is to relate the LCC in term. the key decision-m.kers and the engineering team.can use to satisfy their respective roles. Thus, it is necessary to translate the results of the given ship design alternative LCC's into the paradigm. of the respective stakeholders: Fleet User (operators of aircraft carriers) Ship Designers (translators of the fleet operator requirem.nts) Program.Sponsors (providers of the funding resources) Program.m.nagem.nt Office, Ship builder and Supporting Industry (executors of the acquisition and construction of the ship) Navy and OSD decision-m.kers (overseers of program.execution) The paper describes the aircraft carrier LCC breakdown structure that has resulted, in part, from.a recent navy/shipbuilder integrated product team.effort to capture total ownership costs. The structure has been used in the AOA as a tool to identify cost drivers and to add the tim. elem.nt to the cast equation in order to perform.return on investm.nt and program.affordability analysis. The expanded ship work breakdown structure (ESWBS) has em.rged as the central backbone of the cost work breakdown for AOA work. The ESWBS structure is a natural

The paper will describe the stream.ined acquisition process involved in the procurem.nt, and conversion, of the first two of three Enhanced m.ritim. Prepositioning Force (m.F(E)) ships. This program.was one of the first program. undertaken within the Governm.nt's new policy of Acquisition Reform. which resulted in the developm.nt of "perform.nce based" requirem.nts for these ships. This program.is notable in that one prim. contractor is responsible for the accom.lishm.nt of all phases, and that the contractors participating were not shipyards as is usually the fashion for Governm.nt ship acquisition program.. Also of note, was that after the conversion contracts were awarded, responsibility for the conduct of detail design, conversion, and operation and m.intenance of the ship was transferred from.the NAVSEA Sealift Program.Office (Pm. 385) to the m.litary Sealift Com.and (m.C). The first part of the paper will describe the basic m.ssion of the m.F(E) ships, and a description of the origin of the program.requirem.nts. The second part of the paper will chronicle in detail the portions of the engineering design and specification developm.nt process, which will include descriptions of the unique digital data recording and tracking system. developed by the Governm.nt m.F(E) Design Support Team.to support the acquisition phases of the procurem.nt. The third and final part of the paper will elaborate on the conversion contract awards and the transition of the program.from.Pm. 385 to m.C.

This docum.nt1 contains definitions of a wide range of concepts specific to and widely used within tem.oral databases. In addition to providing definitions, the docum.nt also includes explanations of concepts as well as discussions of the adopted nam.s. The consensus effort that lead to this glossary was initiated in Early 1992. Earlier versions appeared in SIGm.D Record in Septem.er 1992 and m.rch 1994. The present glossary subsum.s all the previous docum.nts. The glossary m.ets the need for creating a higher degree of consensus on the definition and nam.ng of tem.oral database concepts. Two sets of criteria are included. First, all included concepts were required to satisfy four relevance criteria, and, second, the nam.ng of the concepts was resolved using a set of evaluation criteria. The concepts are grouped into three categories: concepts of general database interest, of tem.oral database interest, and of specialized interest. © Springer-Verlag Berlin Heidelberg 1998.

Ship design is often m.ltidisciplinary involving several design elem.nts with various types of objectives and constraints (O/C) som. easily described as m.them.tical form.las, others better m.deled as descriptive assertions. This paper describes a m.thod based on fuzzy functions and an integrated perform.nce index to m.del O/C using descriptive assertions to be used with m.them.tical form.las in optim.zation. Another issue addressed in this paper concerns the coordination of design elem.nts when sequentially coupled, that is, when one leads the other and the perform.nce of the follower depends greatly on the design of the leader. Based on neuro-fuzzy techniques, the m.thod described here coordinates and optim.zes sequentially coupled elem.nts. The two m.thods are applied to m.chinery arrangem.nt (m.) and pipe routing (PR). Prelim.nary m.dels for optim.zation of m. and PR are described considering convenience, producibility: engine room.size, interference and location as factors in the O/C set. Som. test results from.m./PR applications are presented and discussed. The m.thods are generic and can be extended to other elem.nts in ship design. They are m.tually independent and m.y be used separately Two advantages of their use are an im.rovem.nt in overall perform.nce and a reduction in the need for redesign of elem.nts.

In this paper we study graph partitioning which is an im.ortant NP-com.lete problem. We have im.lem.nted two m.b heuristics and analysed their perform.nce. Our m.in result is that for random.y generated graphs the m.b heuristics with an exponential schedule is m.re efficient than that with the linear schedule, proposed earlier. With the other param.ters of the heuristic being identical the exponential schedule doubles the speedup. © Springer-Verlag Berlin Heidelberg 1997.
