COMBAT system engineering - A RETURN TO FUNDAMENTALS

引用

NAVAL ENGINEERS JOURNAL 1993年第3期105卷 61-69页

作者： MITTURA, A KARP, MS PE Andrew Mittura:is currently a senior program engineer with SYSCON Corp. He began his career in the Combat System Installation and Integration Office of NavSea in 1978. He has worked as a system engineer on the Seafire program at NSWCDD on the NATO Anti-air Warfare Program while at FMC Corporation and for the past four years on the Aegis Combat System with SYSCON. Current efforts include performance assessment studies of the Aegis combat system and combat system architecture and connectivity analysis. Mr. Mittura received a B.S. in electrical engineering from Penn State University in 1978 and an M.S. in engineering management from Catholic University of America in 1982. He is a licensed professional engineer with the State of Virginia. Mitchel S. Karp:cofounded K&K Software Engineering Inc. in February 1970. He is currently secretary/treasurer and senior system engineer. His involvement in combat systems began with NTDS in 1963. He has been involved in the Aegis Program since 1968 and has worked in all aspects of combat system development including computer programming tactical analysis software development and management. He has given several seminars on real-time software development and documentation. He currently is working under contracts to NSWCDD in the areas of combat system architecture and connectivity configuration management and documentation. Mr. Karp received a B.S. in engineering physics from Lehigh University in 1958.

The Navy's focus has shifted from global war scenarios to preparedness for the prospect of involvement in regional, littoral contingencies and conflicts. Operationally, shipboard personnel will need the ability to shift focus from the combat system multimission roles to that of only a single mission. From a development perspective, combat systems must accommodate a continual infusion of technology in a budget constrained environment. Combat system architecture is the single most important feature affecting combat system flexibility, from both an operational and developmental aspect. There is a fundamental partitioning of combat svstem functions into detect, command, and engage in a horizontal integration approach that enhances this needed flexibilitv. This fundamental partitioning is currently applied to individual weapon systems, but not to combat svstems as a whole. Instead, self-contained weapon systems are often developed and then vertically integrated to form a combat svstem, causing reduced flexibility. The battle organization is the principal driving requirement for combat system architecture. This paper shows that that the battle organization is best supported by a horizontally integrated combat system of detect, command, and engage. It concludes that a horizontally integrated combat svstem architecture of detect, command, and engage should be a candidate for future combat systems.

The Transient Energy Function (TEF) method has been intensely investigated over the last decade as a reliable and accurate tool for transient stability assessment of multimachine power systems. In this paper we propose the Potential Energy Boundary Surface (PEBS) based method for direct analysis of transient stability. The critical value of transient energy and the Critical Clearing Time (T_CCT) are evaluated without the need for successive calculation and memorization of the system kinetic and potential energy values along the sustained fault trajectory. The method is used for determination of output features in the training phase of the neural‐net based transient security assessment. The proposed approach is tested on the well‐known ten‐generator New England test system demonstrating the validity and accuracy of obtained results. Copyright © 1993 John Wiley & Sons, Ltd.

As technology advances and our dependency on software increases, the requirement to develop the correct means to improve quality in both the deveiopment phase and the maintenance phase of software life cycle support becomes increasingly significant. The focus of this paper is on the dilemma facing software engineering in maintaining quality within the constraints of the maintenance phase. The paper further proposes that the software maintenance process can also be analvzed and improved using statistical process control (SPC) techniques. The methods discussed in this paper have been proposed for use in the Software Maintenance project at NUWC Detachment Norfolk. Upon successful testing at NUWC Detachment Norfolk, they will be forwarded to the AN/SQQ-89(V) (interagencv) Software Quality Evaluation Committee for use by other agencies which are developing and maintaining AN/SQQ-89(V) software.

The Flooding Casualty Control Software (FCCS) was developed under the auspices of the Naval Sea systems Command (NavSea) and is currently being deployed on a variety of ships in the neets of both the U.S. Navy and the U.S. Coast Guard. The primary objective of FCCS is to enable damage control personnel to identify critical stability conditions, especially when related to the loss of reserve buoyancy due to battle damage and the destabilizing effects of large quantities of firefighting water, in a timely manner. FCCS was initially deploved in 1990. It utilizes the standard algorithms of the Ship Hull Characteristics Program (SHCP). The user interface was designed to allow quick familiarity for shipboard users, primarily the damage control assistant (DCA) and his staff. Intact stability evaluations include the effects of topside icing, high winds, personnel crowding, heavy lifts over the side, high speed turns, and towing. FCCS also supports ballasting analysis for amphibious ships as well as providing bottom reaction and beached stability data for grounding incidents. Bv providing a tool for the ''fuel king'' and DCA to generate the required daily updates on the current ship load and liquids status, FCCS is assured of an accurate baseline in the event of damage. The design allows the evaluation of the ultimate ship stability status for a damage event using simple compartmentation and flooding status inputs. Evaluation of the adequacy of resulting stabilitv, as well as identification of such critical stability parameters as off center loading, margin line immersion, and negative GM, are accomplished by the program. Guidance is provided for the user to initiate appropriate flooding related damage control activities. Initially fitted on USS Oliver Hazard Perry Class frigates, FCCS databases have been for the USCG Hamilton class high endurance cutters, USS Arleigh Burke class Aegis destroyers, and a variety of other U.S. Navy and U.S. Coast Guard ship classes.

Scalable High Performance Computing Conference

作者： H. Sato Y. Tanaka H. Iwama S. Kawakika M. Saito K. Morikami T. Yao S. Tsutsumi Computer Systems Architecture Laboratory Fujitsu Laboratories Limited Kawasaki Japan Fujitsu Laboratories Limited Japan Protein Engineering Research Institute Fujitsu Kyushu System Engineering Limited

The authors have parallelized the AMBER molecular dynamics program for the AP1000 highly parallel computer. To obtain a high degree of parallelism and an even load balance between processors for model problems of protein and water molecules, protein amino acid residues and water molecules are distributed to processors randomly. Global interprocessor communication required by this data mapping is efficiently done using the AP1000 broadcast network, to broadcast atom coordinate data for other processors' reference and its torus network; also for point-to-point communication to accumulate forces for atoms assigned to other processors. Experiments showed that a problem with 41095 atoms is processed 226 times faster with a 512 processor AP1000 than by a single processor.< >

引用

NAVAL ENGINEERS JOURNAL 1992年第2期104卷 39-57页

作者： RYAN, JC JONS, OP J. Christopher Ryan:earned his bachelor's and master's degrees in Naval Architecture from Webb Institute and MIT respectively. He spent three years at the Advanced Marine Technology Division of Litton Industries working on the DD-963 class ship design and related computer aided design projects. he subsequently went to the Navy Department concentrating on early stage design of surface combatants for 12 years including work on the FFG-7 Sea Control Ship CSGN and CVV aircraft carrier projects. He then shifted focus and became the technical director for the Computer Supported Design Program in NavSea for five years. Mr. Ryan has served in several supervisory positions within the Ship Design Group in NavSea since that time. He is currently the project manager for the Ship Design Acquisition and Construction Process Improvement Project. Otto P. Jons:received a Diplom Ing. in shipbuilding from the Technical University of Hannover W. Germany and an M.S. in naval architecture and marine engineering from the Massachusetts Institute of Technology in 1967. He then joined Litton Ship Systems where he was responsible for the preliminary design of the DD-963 hull structure and then for ship systems as manager LHA Ship Systems Engineering Department. From 1972 to 1974 he was principal research scientist at Hydronautics. In 1976 as technical director he helped establish the local office of Designers and Planners. Otto Jons was one of the co-founders of Advanced Marine Enterprises Inc. in 1976 where he is corporate vice president engineering.

In the spring of 1990, the NavSea Chief Engineer initiated a project to improve the design, acquisition and construction (DAC) of U.S. Navy ships. The project's objectives are to reduce the time and cost of acquiring and operating Navy ships while improving their quality, unlike previous studies on the subject, the project utilizes a rigorous process analysis approach and attempts to use quantitative measures as the basis for recommending improvements. The paper is, of necessity, a status report on the progress of this project. Topics covered include: the DAC process;a look at the current state of ship acquisition time, cost, and quality;the methodology for process improvements;and early findings.
