Abstract
Abstract
To solve the problem that it is difficult to evaluate and optimize the top-level system design scheme of complex products, a modeling and simulation method of top-level design based on MBSE is proposed. Through the use of SysML to describe the requirements of the system and the functional decomposition and interface of the subsystem, the system model is established; then, the mapping relationship between the SysML model and the Petri net is established, and the SysML model is transformed into the Petri net model. The model is verified by the Petri net simulation tool to evaluate the rationality of the requirements and the completeness of the overall indicators. The simulation results show that100 optimization design variables and 10 optimization constraints can be achieved to meet the requirements.
