JCS Pub 1 defines interoperability as “The ability of systems, units or forces to provide services to and accept services from other systems, units or forces and to use the services so exchanged to enable them to operate effectively together.” With JCS Pub 1 as a foundation, interoperability of systems, units or forces can be factored into a set of components that can quantify interoperability. These components are: media, languages, standards, requirements, environment, procedures, and human factors. The concept described in this paper uses these components as an analysis tool to enable specific detailed analyses of the interoperability of BFC3 systems, units, or forces for the purpose of uncovering and resolving interoperability issues and problems in the U.S. Navy, Joint, and Allied arenas. Also, as a management tool, the components can help determine potential interoperability characteristics of future U.S. Navy BFC3 systems for compliance with battle force systems architectures. The approach selected for the quantification of interoperability was the development of a set of measures of performance (MOPs) and measures of effectiveness (MOEs). The MOPs/MOEs were integrated with a candidate set of components, which were used to partition the totality of interoperability into measurable entities. The methodology described employs basic truth table theory in conjunction with logic equations to evaluate the interoperability components in terms of MOPs that were aggregated to MOEs. It is believed that this concept, although elementary and based on fundamental principles, represents an operationally significant approach rather than a theoretical approach to the quantification of interoperability. The vehicle used as a means to measure the MOPs and MOEs was the Research Evaluation and systems Analysis (RESA) computer modeling and simulation capability at the Naval Ocean systems Center (NOSC), San Diego, Calif. Data for the measurements were collected during a Tactical I

The authors suggest a modification of the Toeplitz approximation method for estimating frequencies of multiple sinusoids from covariance measurements. The method constructs a state-feedback matrix following a low-rank approximation of the Toeplitz covariance matrix via singular-value decomposition. Ideally, the eigenvalues of this state-feedback matrix will be on the unit circle in the complex plane, and the angles that they make with the real axis will be equal to the unknown sinusoid frequencies. The modification proposed here exploits this prior knowledge of the modulus of the eigenvalues and guarantees that even in the presence of noise the eigenvalues of the estimated state-feedback matrix will lie on the unit circle.< >

Miss Hogge's projects at Automaker include: an explosive ordnance disassembly gantry robot system a vision inspection system to examine bearings 3-part camouflage spray painting an investigation of the use of robotic welding in Navy shipyards and rework facilities and epoxy spray painting of missile radomes.

Due to demographical factors, there will be a 25% decline in the national labor pool of eligible 17 to 21 year old men by 1992. As the Navy faces fierce competition with other services and private industry for the dwindling personnel resources of the nation, efforts must be made to consider automating certain tasks, especially those that are hazardous, boring, and labor intensive onboard ships at sea. The Surface Ship Continuing Concept Formulation (CONFORM) Program (SEA-5014) sponsored the Naval Surface Weapons Center's Robotics laboratory to identify potential applications of robotic and artificial intelligence systems to operation and mission activities for shipboard use. The results of the investigation concerning applications of robotics to automate the aforementioned tasks are presented. Changes in current manning levels for selected tasks and ship classes, i.e., CVs, CVNs, LPDs, LPNs, and auxiliaries are examined. Future ship designs incorporating robotics, such as the advance based repair (ABR) ship are discussed. Twenty-four applications were cited in the study which include a remote controlled vehicle for flight deck operations, limited tasks in biological, chemical, and radiation environments, computer aided command decision aids, ordnance handling, undersea search, recovery, and salvage, and ventilation duct cleaning. Four of the applications and their subsequent hardware fruition will be discussed.

At Weston Robertson directs several underground storage tank technology projects ground water modeling studies and serves as senior technical advisor on major nuclear waste disposal programs remedial investigations and ground water protection programs.

A growing number of state and local governments and petroleum-related companies require the use of release detection systems for underground petroleum storage tanks. This has resulted in a confusing array of commercially available petroleum product detection devices, many of which have not been extensively field-tested. These systems, which are installed in ground water observation wells, vapor wells or U-tubes, include hydrocarbon-detecting paste, bailers, interface probes, electrical resistivity sensors, thermal-conductivity sensors, hydrocarbon-soluble devices, hydrocarbon-permeable materials and vapor detectors. This paper describes the available state-of-the-art technology for leak detection and the application for which each system is best suited.

The problem of simplifying the Lagrange dynamic equation of PUMA 600 robot manipulators is considered. By applying the numeric significance evaluation procedure to the symbolically expressed dynamic projection functions, a simplified PUMA arm model is obtained. This model is further optimized by adjusting the model parameters using a least squares error procedure. The simplified/optimized dynamic projection functions have approximation errors less than one percent. © 1985 IEEE.

A METHODOLOGY FOR SETTING COMBAT system REQUIREMENTS

引用

NAVAL ENGINEERS JOURNAL 1985年第4期97卷 274-278页

作者： MENSH, DR The Author received his B.S. and M.S. degrees in applied physics from Loyola College in Baltimore Md. and the American University in Washington D.C. He also has completed his course work towards his Ph.D. degree in computer science specializing in the fields of system analysis and computer simulation. He has been employed at the Naval Surface Weapons Center White Oak Laboratory Silver Spring Md. for the past eighteen years in the areas of weapon system analysis and the development of weapon system simulations. Since 1978 he has been involved in the development of simulation tools that can be applied to the solution of shipboard combat system architecture and engineering problems. Currently at the White Oak Laboratory he is responsible for the application of and further development of the single ship combat system simulation.

This paper describes a methodology for setting combat system requirements for all ship classes. The requirements are determined from a battle group perspective. The methodology uses ship damage as a measure of effectiveness for setting combat system requirements. The ship damage data used was derived from the Navy tactical game (NAVTAG). The methodology that determines ship class combat system requirements consists of a set of logical steps that are iterative by design. It provides insight and valid estimates of numerical measures of defined force requirements at several levels. This process is not trivial; the expected level of effort could be significant. The method consists of five basic stages considered necessary to achieve valid results. These stages are (1) determination of force level requirements, (2) determination of force level capability, (3) analysis of force level capability, (4) determination of class requirements by battle overviews, and (5) determination of class requirements — overall. The methodology was used by the combat system master plan (CSMP) manager for determining top level combat system requirements for individual platforms in a battle group. In addition, once levels of combat system performance have been defined, this methodology generates a quantitative data base that becomes a useful tool in ship combat suite selection. Once alternate combat system suites have been defined, these suites can be analyzed in terms of combat system performance capability versus cost.

IFAC Proceedings Volumes 1984年第2期17卷 1145-1146页

作者： D.P. Bertsekas Laboratory for Information and Decision System. Department of Electrical Engineering and Computer Science Massachusetts Institute of Technology. Cambridge MA 02139 USA

We consider a model of distributed iterative algorithms whereby several processors participate in the computation while collecting, possibly stochastic information from the environment or other processors via communication links. Several applications in distributed optimization, parameter estimation, and communication networks are described. Issues of asymptotic convergence and agreement are explored under very weak assumptions on the ordering of computations and the timing of information reception. Progress towards constructing a broadly applicable theory is surveyed.

SHIP COMBAT system SIMULATION (SCSS)

引用

NAVAL ENGINEERS JOURNAL 1984年第3期96卷 142-148页

作者： MENSH, DR The Authorreceived his B.S. and M.S. degrees in applied physics from Loyola College in Baltimore Md. and the American University in Washington D.C. He also has completed his course work towards his Ph.D. degree in computer science specializing in the fields of system analysis and computer simulation. He has been employed at the Naval Surface Weapons Center White Oak Laboratory Silver Spring Md. for the past seventeen years in the areas of weapon system analysis and the development of weapon system simulations. Since 1978 he has been involved in the development of simulation tools that can be applied to the solution of shipboard combat system architecture and engineering problems. Currently at the White Oak Laboratory he is responsible for the application of and further development of the Single Ship Combat System Simulation.

This paper will describe a combat system integration and analysis tool called the Ship Combat system Simulation (SCSS). The SCSS was designed as an analysis tool to study sensor command and control and weapon system integration for shipboard combat systems. The simulation represents the combat system components as nodes in a network. Data flows between the nodes through the links. SCSS is a structured program simulation written in Simscript II.5. The structured program feature allows for ease of combat system reconfiguration into different types of architectures. Consequently, SSCS can be used to study and analyze different combat system architectures. Currently the model has an antiairwarfare (AAW) capability and a partial antisurface warfare (ASUW) capability. The model has been used in ship vulnerability and survivability studies, individual combat system component studies, component trade-off analysis; and total system reaction time analysis. Figure 1 presents a sample of a SCSS link-node diagram. Figures 8 and 9 present combat system sequence and timing diagrams. The model boasts a postprocessing capability that includes both statistics and graphics packages. The SCSS has been developed jointly by the Naval Weapons Center, Naval Ocean systems Center, Naval Surface Weapons Center, Naval Ships Weapons systems engineering Station, and CACI, Inc. SCSS is supported by naval and industrial laboratories throughout the country. The users of the simulation belong to the SCSS User's Group which meets periodically throughout the year. Members of the User's Group develop equipment nodes and exchange ideas. The User's Group maintains SCSS configuration management allowing for Simscript II.5 code written by any one user to be used by all other users.

To meet energy conservation goals of the U.S. Navy, its attention has been focused on ways to reduce individual ship total resistance and powering requirements. One possible method of improving ship powering characteristics is by modifying existing individual ship hulls with the addition of bulbous bows. This paper will identify the merits of retrofitting bow bulbs on selected U.S. Navy auxiliary and amphibious warfare ships. A procedure for performing a cost-benefit analysis will be shown for candidate ship classes. An example of this technique for an amphibious warfare ship will also be provided. A brief discussion of future methods to be used for bulbous bow design such as application of systematic model test data and numerical hydrodynamic techniques will be given.
