Abstract

Disclosed is a unified modeling method supporting design and simulation of a complex system. Two forms of models of the complex system are established according to a preset graph and text modeling framework, mutual conversion of the two forms of the complex system model is achieved through an image-text conversion modeling tool, and finally the code is explained into a C++ code through an interpreter, and simulation runs in a DEVS simulator environment. System design and simulation verification of a complex system model are integrated through two modeling forms of graphs and texts, the efficiency of the research and development process of the complex system is improved, the learning cost of modeling personnel is reduced, the difficulty in changing the design of the complex system model is avoided, and the consistency is difficult to guarantee.

Description

technical field [0001] The invention relates to a unified modeling method supporting complex system design and simulation, and belongs to the technical field of complex system modeling. Background technique [0002] With the continuous improvement of science and technology and demand, especially in the military and manufacturing fields, the complexity of the research object is also gradually increasing. The traditional document-based system engineering method brings great difficulties and challenges to modelers. With the rapid development of computer technology, Model-Based Systems Engineering (MBSE) has gradually become a mainstream method in the field of system design and simulation modeling of complex systems and even systems. The model-based R&D model has many advantages such as reusability, unambiguity, easy understanding, and easy reuse. At present, the mainstream modeling language of MBSE is the system modeling language SysML (System Modeling Language), based on Sys...
