ROLE OF SIMULATION IN RAPID PROTOTYPING FOR CONCEPT DEVELOPMENT

NAVAL ENGINEERS JOURNAL 1991年第3期103卷 204-211页

作者： KING, JF BARTON, DE J. Fred King:is the manager of the Advanced Technology Department for Unisys in Reston Virginia. He earned his Ph.D. in mathematics from the University of Houston in 1977. He has been principal investigator of research projects in knowledge engineering pattern recognition and heuristic problem-solving. Efforts include the development of a multi-temporal multispectral classifier for identifying graincrops using LANDSAT satellite imagery data for NASA. Also as a member of the research team for a NCI study with Baylor College of Medicine and NASA he helped develop techniques for detection of carcinoma using multispectral microphotometer scans of lung tissue. He established and became technical director of the AI Laboratory for Ford Aerospace where he developed expert scheduling modeling and knowledge acquisition systems for NASA. Since joining Unisys in 1985 he has led the development of object-oriented programming environments blackboard architectures data fusion techniques using neural networks and intelligent data base systems. Douglas E. Barton:is manager of Logistics Information Systems for Unisys in Reston Virginia. He earned his B.A. degree in computer science from the College of William and Mary in 1978 and did postgraduate work in London as a Drapers Company scholar. Since joining Unisys in 1981 his work has concentrated on program management and software engineering of large scale data base management systems and design and implementation of knowledge-based systems in planning and logistics. As chairman of the Logistics Data Subcommittee of the National Security Industrial Association (NSIA) he led an industry initiative which examined concepts in knowledge-based systems in military logistics. His responsibilities also include evaluation development and tailoring of software engineering standards and procedures for data base and knowledge-based systems. He is currently program manager of the Navigation Information Management System which provides support to the Fleet Ballistic Missile Progr

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.

DESIGN, CONSTRUCTION, AND MODERNIZATION OF SHIPS WITH THE SHIPBOARD DATA MULTIPLEX SYSTEM (SDMS)

NAVAL ENGINEERS JOURNAL 1979年第5期91卷 65-73页

作者： BOLD, NT BOURETTE, AP Dr. Norbert T. Bold graduated from Marquette University and later received his M.S. and Ph.D. degrees in Electrical Engineering from Northwestern University. He served three years as a Naval Engineering Officer aboard an Aircraft Carrier and a Minesweeper and has nineteen years technical experience in shipboard navigation underwater target and SDMS projects for the Navy. He is currently a Program Manager in the Autonetics Marine Systems Division Rockwell International where his primary assignment is the development of advanced concepts and applications of SDMS to Navy programs. He has published several technical papers. was elected to four Scholastic Honorary Societies and was the recipient of a NROTC Scholarship. Mr. A.P. Bourette Manager Systems Applications Autonetics Marine Systems Division. received his B.S. degree in Mathematical Physics from Long Beach State University. He began his career with a Computer Analysis Unit. performing tasks related to computer application. programming and interfacing. He has made significant contributions to the Central Computer Complex approach adopted for the SSN-688 Combat System and has performed inertial systems engineering efforts on the MK2 SINS for the POSEIDON Program. He spent some time in the Washington D.C. area providing technical expertise to various Navy organizations. Upon his return he soon was selected to manage the Systems Applications organization at Rockwell International. This organization is primarily responsible for the Shipboard Application of SDMS. He has directed several application studies showing the significant advantages associated with multiplexing. Recently. he provided the technical direction for the FY80 SSN SDMS Preliminary Design Phase.

Rockwell International is currently under Navy contract to fabricate the Engineering Development Model (EDM) of the Shipboard Data Multiplex System (SDMS) for general data transfer aboard surface ships and submarines. The application of SDMS significantly reduces hardware such as cables, switchboards, and Signal Data Converters (SDC), and it provides the capability to add many desired features which are currently not practicable. In applying SDMS to a specific ship, a massive amount of signal data must be considered. The Application Design Automation Program (ADAP) is a set of computer programs that have been developed to accomplish this task. ADAP com bines signal population data, ships configuration data, and SDMS hardware characteristics to produce an SDMS configuration layout together with documentation necessary to analyze, evaluate, and implement the system. Specific outputs include hardware requirements, system layout, and interface requirements including wire list information. The Timing, Event and Load Simulation (TELS) Program simulates SDMS and provides performance data (system capacity, throughput rate, transport delays) for any system configuration. Conventional SDCs can be elimianted from Navy shipboard systems when SDMS is used. SDMS provides the necessary data distribution, signal conversion, and computer interface. In addition, many functions of the conventional switchboards can be performed within SDMS, thus reducing the size or eliminating conventional switchboards. Very small switch-bomb will provide the necessary control of data distribution. With SDMS, an automatic and continuous Noise and Vibration Monitoring (NVM) capability is readily available. The automated NVM function will enhance the safety, operation, and maintenance of the ship. Problems with machinery or excessive self-noise generation will be detected much sooner, and corrective action implemented on a timely basis.
