Modeling the behavior of a complex product is one of main methods to help engineers to coordinate separate disciplines in different stages of the product development.As a modeling language,the SysML (System Modeling Language) models behaviors in a standard way.In addition to the graphics-based modeling methods,matrix-based modeling methods also provide a possible approach for analyzing complex system,DSM (Design Structure Matrix) is one of them.Although both approaches model system behaviors commonly,they are hardly used together.This paper aims to utilize the advantages of both approaches to enhance the entire development process by generating DSM form SysML behavior diagram.
