X Language: An Integrated Intelligent Modeling and Simulation Language for Complex Products

Modeling and simulation have become an important means of supporting analyses and development of complex products. At present, for the development of full-process and full-system modeling and simulation, system modeling languages (such as SysML) are often required to cooperate with multi-physics modeling languages and simulation platforms (such as Modelica, Simulink), which is difficult to ensure the true unity of the whole system, the consistency between the various layers and the traceability of the modeling and simulation process. In response to this problem, this paper proposes a new integrated intelligent modeling and simulation language—X language, which supports the description of system-layer structure and physical behavior, as well as modeling of complex agent models. Interpreter and engine are developed to enable X language to support the simulation of continuous, discrete event and agent models. Finally, the tank model is taken as a case to verify the modeling and simulation capabilities of the X language.
