To address the development needs and traction issues of intelligent equipment for urban combat, a city combat system based on the DoDAF (Department of Defense Architecture Framework) and parameter diagrams is developed. Starting from a deep analysis of the requirements of urban combat systems, a framework for combat concept systems is constructed, and future combat scenarios are designed based on this. The study employs the top-level framework and conceptual models of DoDAF, combined with parameter diagrams as analytical tools, to effectively understand and analyze key parameters and variables in combat systems. Through practical cases, it is demonstrated that providing a new perspective and method for the design of urban combat systems, which helps improve combat efficiency and decision-making quality.
