1 Enterprise-wide Requirements & Decision Management

INCOSE International Symposium 1999年第1期9卷 644-650页

Decision-making is one of the most fundamental processes contributing to a corporation's success, yet in many companies, decisions are often characterized as ad-hoc events without a clear linkage to supporting information, tradeoff studies, or clearly stated rationale. Furthermore, the "information" used to support these decisions is often in the form of complex, unstructured documents which lack clear linkages between their content. As a result, future decision-makers are often not able to benefit from the collective experiences of their predecessors. Consequently, there are no cycles of learning and the same mistakes are often repeated each time that a similar decision is made. It is clear that the most successful companies in the future will be those who can effectively manage and leverage the "intellectual capital" generated by the decision making process (the thinking engine of systems engineering) and the linkage of that process to essential supporting information. This paper describes an approach to address the deficiencies in the prevailing methods for requirements and decision management by proposing an enterprise-wide approach which provides for a true "learning organization" capability in the form of reusable decisions frameworks. © 1999 The Authors.

3 Capturing and Leveraging Essential Organizational Knowledge via Dynamic Roadmaps

INCOSE International Symposium 1999年第1期9卷 367-374页

作者： Hansell, Todd DeGregorio, Gary Motorola Inc. Motorola Labs Software System Engineering Research Laboratory 1301 E. Algonquin Road Schaumburg IL60196 United States

In many companies today, technology, capability, and product planning information is maintained in a haphazard collection of overhead slides, spreadsheets, and private databases by a set of disconnected "experts" and updated sporadically (usually just in time for the next review!). This information is often quite sparse and poorly supported by knowledge and supporting data, often being held only in the heads of the "experts." Therefore, it is often difficult to leverage as external technology and market forces continue to change. In an attempt to improve the technology planning process and to provide the basis from which a company can develop its roadmap planning as a competitive asset, a set of methods, tools, and workshop-based training have been developed. These assist the technology strategists, systems engineers, marketing professionals, and product development managers in creating, leveraging, and maintaining an organization's critical knowledge in a dynamic fashion. © 1999 The Authors.

The Farmer model is a basic model of the farming methodology that loads the component defined in the aspect-object from the PICR into the distributed object after analyzing the real world entity in various aspects and defining the aspect elements as the Aspect-Object. This model is a model that formalizes the concept of downloading the componentware from the PICR to the distributed entity node type that describes the abstract object, the aspect node type that describes this object, the link type that shows the relativity between the entity and the aspect, and the attribute type that shows the characteristics of the entity. In this paper, the platform independent TMN agents are designed by the diagram of the Farmer model.

This paper targets engineers and practitioners who want a simple procedure to compute the mean performance measures of the Batch Markovian Arrival process (BMAP/G/1) queueing system when the parameter matrices order is very low. We develop a set of system equations and derive the vector generating function of the queue length. Starting from the generating function, we propose a spectral approach that can be understandable to those who have basic knowledge of M/G/1 queues and eigenvalue algebra. ©2003 by North Atlantic Science Publishing Company.

A Holonic Manufacturing system (EMS)is a manufacturing system where key element, such as machines, products, park, etc., have artonomous and cooperative properties. These element are called "holons" a word coined by combining "holos" (the whole) and ‘onu (a particle) following Koestler. In an HMS, each "holos" activities are determined through cooperation with other holons, as opposed to being determined by a centralized mechanism. An EMS could therefore enjoy high agility, which is an important characteristic for future manufacturing systems. Effective cooperation of holons for overall system performance, however, is mostly an open issue. In the paper, the holonic concept is applied to a simple robotic assembly testbed, and cooperation mechanism among holons for planning and schedukng are established, respectively, baaed on an adaptive consistency algorithm and the Lagrangian relaxation technique. It turns out that Lagrangian relazation provides a theoretical,foundation for the cooperation of scheduling activities among holons. The system has been implemented in object-oriented framework, and evaluated based on the computation times for generating assembly plans and scheduler and the quality of schedules under different circumstances. Preliminary testing showed that the system can generate assembly plans and high quality schedules, and respond to dynamic changes. © 1994 IEEE.

There is a very large demand for basic telephone service in developing nations, and remote parts of industrialized nations, which cannot be met by conventional wireline and cellular systems. This is the world's largest unserved market. We describe a system which uses recent advances in active phased arrays, fast-packet switching technology, adaptive routeing, and light spacecraft technology, in part based on the work of the Jet Propulsion laboratory and on recently-declassified work done on the Strategic Defense Initiative, to make it possible to address this market with a global telephone network based on a large low-Earth-orbit constellation of identical satellites. A telephone utility can use such a network to provide the same modern basic and enhanced telephone services offered by telephone utilities in the urban centres of fully-industrialized nations. Economies of scale permit capital and operating costs per subscriber low enough to provide a service to all subscribers, regardless of location, at prices comparable to the same services in urban areas of industrialized nations, while generating operating profits great enough to attract the capital needed for its construction. The bandwidth needed to support the capacity needed to gain these economies of scale requires that the system use K(alpha)-band frequencies. This choice of frequencies places unusual constraints on the network design, and in particular forces the use of a large number of satellites. Global demand for basic and enhanced telephone service is great enough to support at least three networks of the size described herein. The volume of advanced components, and services such as launch services, required to construct and replace these networks is sufficient to propel certain industries to market leadership positions in the early 21st Century.

Intention recognition using conceptual fuzzy sets

Intention recognition using conceptual fuzzy sets

IEEE International Conference on Fuzzy systems (FUZZ-IEEE)

In the man-machine interface, the user's goal is transmitted to the system, the system understands the goal, and the processing is carried out. The status of the system and the processing result are transmitted to the user. Therefore, to realize this communication, it is necessary to recognize a user's intention from his or her words. This intention recognition raises the computer system to the information processing level of a human. A conceptual fuzzy set (CFS) represents the context-dependent meaning of a vague concept. Multilayered reasoning (MLR) based on CFS can provide abstract and concrete representation simultaneously, and can handle top-down and bottom-up processing simultaneously. The authors apply MLR based on CFS to intention recognition. Goal recognition for a drawing tool is used as a concrete example. The multistructured knowledge for goal recognition is represented using CFS, and is inductively constructed using the Hebbian learning law.< >

The development of large, complex systems consisting of both hardware and software normally involves several companies and/or development teams for the development of the different subsystems forming the entire system. Depending on the kind of subsystem to be developed, these different development teams normally use different system engineering methodologies and/or tool sets to produce their subsystems. However, the usage of different methodologies and tools makes technical management and quality assurance for the entire development effort a difficult task. Therefore the development as well as the maintenance of future systems with their increasing size and complexity requires a common frame for the entire system development and maintenance effort covering different kinds of subsystems, like graphical user interfaces, database systems, expert systems, real-time systems, and so on. This common frame should support the separate and independent development of the different subsystems by different subcontractors using different system engineering methods, the integration of these subsystems to the entire system as well as the maintenance of the entire system. A hierarchical object-oriented model for the encapsulation and integration of different system engineering methods can serve as this common frame, providing traceability from the system requirements model to the implemented system while giving each subsystem development team full scope in choosing the system engineering method most suitable for a specific subsystem. The approach underlying this object-oriented model is the encapsulation of the different subsystems in "high-level objects," which can be either further decomposed into "high-level object" or described in more detail using any appropriate system engineering method. The integration of these "high-level objects" to the entire system is supported by a "definition object" on each layer of each system engineering model. The "definition objects" provide trace

A valuable technique during concept development is rapid prototyping of software for key design components. This approach is particularly useful when the optimum design approach is not readily apparent or several known alternatives need to be rapidly evaluated. A problem inherent in rapid prototyping is the lack of a "target system" with which to interface. Some alternatives are to develop test driver libraries, integrate the prototype with an existing working simulator, or build one for the specific problem. This paper presents a unique approach to concept development using rapid prototyping for concept development and scenario-based simulation for concept verification. The rapid prototyping environment, derived from artificial intelligence technology, is based on a blackboard architecture. The rapid prototype simulation capability is provided through an object-oriented modeling environment. It is shown how both simulation and blackboard technologies are used collectively to rapidly gain insight into a tenacious problem. A specific example will be discussed where this approach was used to evolve the logic of a mission controller for an autonomous underwater vehicle.

He is currently the lead software engineer on the Command Support At-Sea Experiment Project.

The Command Support At-Sea Experiment (CS@SE) provides experimental advanced graphics display systems consisting of large screen color displays and operator console color displays in the combat information center (CIC) of an Aegis cruiser and in the tactical flag command center (TFCC) of an aircraft carrier. CS@SE systems are designed to prototype potential command support capabilities in an at-sea environment to validate and refine requirements for planned production system upgrades. These systems use sophisticated color graphics techniques to provide real-time tactical displays that improve the availability of information to an operator by reducing clutter through the use of color, area fill, transparen overlays and intensity coding of track symbols. Interfaces wen developed with the Aegis Display system (ADS), Shipboarc Gridlock system with Auto-correlation (SGS/AC), Flag Dats Display system (FDDS) and Tomahawk Engagement Planning and Exercise Evaluation system (TEPEE) that provided the data for the presentation of a tactical display. Display elements included both real-time and over-the-horizon (OTH) surface track data, velocity leaders, tags, uncertainty ellipses, and history trails. The display also included filled land masses, country boundaries, commercial airways, cities, graphics overlays (i.e., operational areas), weapon system missile performance contours, and engagement plans. This paper describes the experiment, its installation and integration into the shipboard environments of an Aegis cruiser (USS Leyte Gulf ) and an aircraft carrier (USS America , its usage by the ships companies and embarked staffs, and the experiment result! and findings. Key conclusions of the experiment are: 1 Advanced graphics color displays can significantly enhance the ability of the warfighter to assimilate a complex tactical display. 2 Both ships reported a requirement for a correlated OTH and real-time track display with the ability to clearly differentiate the two types
