Active Conceptual Modeling Technology Supporting Joint C4ISR Navy SBIR FY2008.1 Sol No.: Navy SBIR FY2008.1 Topic No.: N08-101 Topic Title: Active Conceptual Modeling Technology Supporting Joint C4ISR Proposal No.: N081-101-1281 Firm: Chen & Associates, Inc. 5261 Highland Road, #315 Baton Rouge, Louisiana 70808-6547 Contact: Li Ho Phone: (225) 769-1674 Web Site: www.peterchen.com Abstract: This project proposes to study the core concepts of Active Conceptual modeling (A-CM) with applications to military and commercial systems. We plan to explore the feasibility of extending the mathematical framework for Entity-Relationship (ER)-based active conceptual modeling developed by Dr. Peter Chen to represent scenario snapshots that include time, space, uncertainty, and perspective dimensions. the mathematical framework will be based on set theory, Modern algebra, and other branches of mathematics. We also plan to explore mechanisms for the computation and representation of differences between snapshots for model evolution. In Phase I, we will evaluate the feasibility of developing information services derived from active conceptual modeling. We plan to identify a set of information services that will be benefited by the A-CM technology. We also plan to design and implement a simple version of one or more such information service tools to test the feasibility and validity of the mathematical framework and the representation and computation of the conceptual model difference mechanism. Benefits: The current database management systems (DBMS) and information systems are designed to keep track of static data of the current state of the world. It can not handle the historical data and the time dimension very well. If the Phase I and, later, the Phase II efforts of this proposed project are successful carried out, this will create a commercial product of a new type of DBMS and/or a set of information services and tools. Active conceptual modeling can be used for developing dynamic business process models in Service Oriented Architectures (SOAs). Results from the proposed technology development will yield new information services, which are applicable to military and commercial applications including law enforcement, info-forensics, lessons-learned systems, medical/patient information systems, and automated information archiving systems.
