System Performance Modeling in C4ISR/Weapon System Design and Development

摘要

This paper describes an effective process for development of engineering models and discrete event simulations as part of the system engineering effort supporting Command, Control, Communications, Computers, Intelligence, Surveillance, and Reconnaissance (C4ISR) and weapon system development. Application of modeling and simulation techniques throughout the system life cycle has been directed as an element of Defense acquisition reform, and has been demonstrated to be effective in reducing cost, risk, and improving system performance. Development of an executable model of the proposed system, which encompasses the functional architecture, process models, rules, and a data representation, allows the architect to ensure the design concept meets functional requirements. When this is carried a step further by developing a simulation of the architecture, or architectural components, it becomes possible to assess performance capabilities. A virtual model of the system can be executed to predict these characteristics and validate its likely fulfillment of operational requirements. This paper provides a step-by-step discussion of a process for developing system performance models and simulations, concluding with a synopsis of key areas for program manager attention.
