In this paper we develop a subjective Effects-Based Assessment method. This method takes subjective assessments regarding the activities of a plan as inputs. From these assessments and a cross impact matrix that represents the impact between all elements of the plan we calculate assessments for all other plan elements. The method is based on belief functions and their combination under a new generalization of the discounting operation. The method is implemented in a Collaboration Synchronization Management Tool (CSMT).

The Defence Conceptual Modeling Framework (DCMF) is the Swedish Defence Research Agency's (FOI) proposal for conceptual modeling in the military domain. DCMF enables the conceptualization, composition, visualization, and reuse of knowledge for modeling and simulation. To achieve these aims, DCMF requires that its final products- conceptual models expressed as Base Object Models (BOMs)-are embedded with semantics. In this study, this is accomplished by formalizing them through the use of an ontology. These semantically enriched models are better able to achieve key requirements of DCMF, mainly conceptualization and reuse of knowledge. Such requirements are crucial when conceptual models are stored for later use in a repository.

The Defence Conceptual Modelling Framework (DCMF) is the Swedish Defence Research Agency's (FOI) proposal to deal with conceptual modelling in the military domain. The vision of the DCMF is to enable composability, interoperability and reuse of knowledge for modelling and simulation. The final products, the conceptual models, are called Mission Space Models (MSMs), following the original CMMS proposal (proposed by the US DoD). However, the representation formalisation for the MSMs is still under research. To find a suitable representation template we are currently investigating several proposals of which the Base Object Model (BOM) is one. In this paper, we introduce two different proposals for semantic enhancements of BOM for enabling representation of the MSM conceptual models.

MILCOM, Military Communications Conference

作者： Johan Schubert Robert Suzic Department of Decision Support Systems Division of Command and Control Systems Swedish Defence Research Agency Stockholm Sweden

In this paper we describe the development of a decision support system for crowd control. decision support is provided by suggesting a control strategy needed to control a specific current riot situation. Such control strategies consists of deployment of several police barriers with specific barrier positions and barrier strengths needed to control the riot. The optimal control strategy for the current situation is found by comparing the current situation with pre-stored example situations of different sizes. The control strategies are derived for these pre-stored example situations by using genetic algorithms where successive trial strategies are evaluated using stochastic agent-based simulation.

The NATO Research and Technology Agency has set up the Modeling and Simulation Group (MSG) 058 with title "Conceptual Modeling for M&S" to produce guidance on conceptual modeling for modeling and simulation (M&S) development within NATO. The Task Group is comprised of CAN, ESP, NOR, NLD, ROM, SWE, TUR and USA. This paper introduces the group's mandate and reviews the state-of-the-art of doing conceptual modeling. Current M&S standards, such as DIS and HLA, have provided the first steps to composability, interoperability, and reuse, but they are not sufficient to support understanding simulation development and to facilitate semantic consistency at the conceptual level of consequent simulation products. Systematic conceptual modeling will help to improve common understanding between stakeholders that are involved in simulation development, composition, and use for the defense establishment. This will lead to better requirement specification;and it is key to the transformation of requirements to implemented simulations fit for their intended use. NMSG-058 is committed to clarify the process and results of "Conceptual Modeling", and to recommend best practice to generate, document, and use conceptual models. The group is studying the fundaments of conceptualization of existing and prospective realities;methodologies for generating, documenting, and sharing conceptualizations;correlation of conceptual modeling with simulation and software engineering processes;and relevant initiatives and technologies. The main deliverable is a guide on the conceptual modeling process and product, that will provide best practice instruction and serve the needs of relevant stakeholders. Furthermore, the group is committed to offering the results of its efforts as the basis for establishment of a SISO standard. Copyright © 2008, SISO, Inc.

European Radar Conference (EURAD)

作者： Maria Andersson Michael Ilestrand Department of Decision Support Systems Division of Command and Control Systems Swedisch Defence Research Agency Linkoping Sweden Department of Computer and Information Science Linköping University Linkoping Sweden

The paper presents methods for increasing robustness of civil air-traffic monitoring systems, with secondary surveillance radars (SSR) and primary radars, against intentional jamming. Jamming could cause large problems to civil air traffic from an economically point of view as well as increase the risk for serious accidents. The methods are based on a sensor network and data fusion. In a sensor network false objects do not appear simultaneously in different sensors. Consequently, data fusion methods can be used to reveal false objects. The data fusion methods discussed are; statistical distance, covariance intersection and hidden Markov models (HMM). The statistical distance is used to associate data from different sensors. The covariance intersection is used to fuse data from different sensors. HMM is used to describe the behaviour of an aircraft. The paper discusses the use of these methods on this application and presents some simulation results.

AEGIS CRUISER SHIP systems-ENGINEERING IMPROVEMENTS

NAVAL ENGINEERS JOURNAL 1987年第3期99卷 181-189页

作者： HOLMES, RW The authorreceived a BSEM degree from Norwich University. After working in the Industrial Engineering Department of Eastman Kodak Company in Rochester NY he went to work for the Navy at the Naval Ship Engineering Center Philadelphia Division (now NAVSSES). He held a variety of assignments in the Heat Power Systems Department and the Machinery Systems Department. He was promoted to a project engineer position in the Gas Turbine Branch and was a project engineer on the DD-963 class propulsion plant land based test. Upon completion of DD-963 class testing and training he transferred to the Naval Sea Support Center Pacific in San Diego. He worked as afield engineer in the Gas Turbine and Control Systems Branch working on a variety of assignments in the fleet primarily aboard DD-963 and FFG-7 class ships. After several years at Naval Sea Support Center Pacific he accepted a position at the Naval Sea Systems Command initially in NAVSEA 05 later transferring to the Aegis Program (PMS 400). He worked on a number of ship systems engineering assignments in the Aegis Cruiser Division where he now serves as the Aegis cruiser technical director. In 1986 he received the Department of Defense Productivity Excellence Award presented by the Honorable Caspar W. Weinberger.

The CG-47 class design process differed from some other ship design processes (such as DD-963, FFG-7, or DDG-51) in that it had to start from a fixed baseline, the DD-963 and DDG-993. Commonality with DD-963 propulsion, electrical, auxiliaries, and hull systems were the design guidelines. The advantage of this philosophy was to get Aegis technology to sea quickly, in a proven hull form. This approach, however, had the disadvantage of fitting more equipment and accommodations into the same hull and inherited DD-963 class problems. This did not necessarily force CG-47 class ships to be built with known deficiencies, however. Through a dedicated ship systems engineering effort, equipment and systems changes and improvements were made and advantage was taken of new technology in the design of USS Ticonderoga (CG-47), and even later follow-on cruisers. This paper describes some of the major HM & E improvements and technical initiatives introduced into CG-47 class ships. The paper presents a synopsis of ten ship systems case studies, followed by three examples of current projects that offer promise. The critical elements of management philosophy are summarized.

This paper provides a context within which the role of human factors engineering (HFE) for Naval ship design may be understood. HFE is defined and its history as part of engineering design teams is traced. The role of HFE in ship systems design is defined, and the HFE Technology for Ships Program, managed by SEA 061R, is described. The rationale for inclusion of HFE in the design process is presented, the methodology whereby it is incorporated into the design process is detailed, methodology to assess the application of HFE is outlined, and the benefits that will accrue as a result of inclusion of HFE considerations in the design process are documented. The counterpoint to inclusion is illustrated through instances of design-induced human errors. A specific application of HFE in the acquisition process is illustrated through use of the Landing Craft, Air Cushion HFE program plan. The difficulties which may be encountered as the size of the target system expands are described. Potential roadblocks to the required incorporation of HFE are examined for their source and possible ameliorative steps.
