Problems solved by technology

[0006] (1) Continuous behavior is described in plain text, lacking formal model representation;
[0007] (2) The parameter relationship between behavior and structure is difficult to express;
[0008] (3) State (State) is not an instantiable model element, so it cannot support state reuse, making the entire behavior model lack of reusability

Embodiment Construction

[0040] Such as figure 1 As shown, the implementation steps of the SysML-based multi-domain complex product system layer behavior modeling method in the embodiment of the present invention are as follows:

[0041] 1) Obtain the physical components contained in the physical subsystem in the system layer design model;

[0042] 2) Dynamically model the continuous behavior of each physical component based on the SysML parameter graph;

[0043] 3) The block and attribute in the SysML parameter diagram are defined with order requirements, and the ordered parameter diagram with ordered constraint blocks and ordered constraint attributes is expanded to form an ordered parameter diagram, and the discrete behavior of each physical component is calculated based on the ordered parameter diagram. Modeling, and based on the ordered parameter graph view fusion mechanism, the discrete behavior and the continuous behavior are fused to achieve mixed behavior modeling;

[0044] 4) Obtain the fu...

Abstract

The invention discloses a multidomain complex product system layer behavior modeling method based on a SysML. The behavior modeling method is implemented through the following steps of: 1) acquiring physical members contained in a physical subsystem; 2) on the basis of a SysML parameter diagram, carrying out dynamic modeling on continuous behaviors of all the physical members; 3) expanding the SysML parameter diagram to form an order parameter diagram, carrying out modeling on discrete behaviors of all the physical members on the basis of the parameter diagram, and fusing the discrete behaviors and the continuous behaviors on the basis of a view fusion mechanism of the order parameter so as to realize modeling of mixed behaviors; 4) acquiring all function modules of a control subsystem; 5) carrying out modeling on the discrete behaviors and continuous behaviors of control function blocks, and realizing fusion modeling of continuous parts and discrete parts of the mixed behaviors; and 6) connecting the physical members and the control function blocks by connectors. The behavior modeling method has the advantages of unified modeling method, convenience in use, fastness and high efficiency.

Description

technical field [0001] The invention relates to the field of model-based system engineering, in particular to a SysML-based multi-domain complex product system layer behavior modeling method during multi-domain complex product system layer design. Background technique [0002] With the development and progress of society, the problems people study become increasingly complex. This type of extremely complex research object is called a system, which is an organic whole with specific functions composed of interrelated and interdependent parts, and each system itself is a part of a larger system. Systems engineering It is a discipline created for the study of such complex systems. With the extreme expansion of system information and the increasing complexity of the system, the traditional document-based system engineering gradually shows its disadvantages. Therefore, Model-Based Systems Engineering (MBSE) came into being. It has The unambiguous nature of knowledge representati...
