Embodiment Construction

[0029] The technical solutions of the present invention will be described in further detail below in conjunction with the accompanying drawings and implementation examples, and the following implementation examples are not intended to limit the present invention.

[0030] Such as figure 1 As shown in the method flow chart, the present invention is based on the system modeling language SysML to realize the integration of multi-domain complex system design and system optimization, including the following steps:

[0031] Step 1. Formally represent the system optimization method based on SysML, and use the SysML extension mechanism to define the representation specification of the system design model.

[0032] Specifically, the formal representation of the system optimization method based on SysML is to formally define the currently popular system optimization methods based on SysML, so that these optimization methods can be automatically called in the system design platform in su...

Abstract

The invention discloses a multi-domain system design and optimization method. The multi-domain system design and optimization method comprises the steps of presenting a system optimizing method in a formalized mode on basis of system modeling language SysML(System Modeling Language), and defining the presentation standard of a system design model by a SysML extension mechanism; analyzing according to the functional demands of a multi-domain system to be designed and optimized, establishing a system design model on basis of the presentation standard, and automatically extracting a system optimizing model; and invoking a system optimizing method to automatically solve the system optimizing model, returning an optimizing result to a system optimization model, and optimizing the system design model according to the optimizing result. According to the method disclosed by the invention, the system design and the system optimization can be combined effectively, and the automatic optimization of the system can be realized in the system design process.

Description

technical field [0001] The invention relates to the technical field of system engineering, in particular to a method for designing and optimizing a multi-domain system. Background technique [0002] The so-called system refers to an organic whole with certain functions composed of interrelated, mutually restrictive and interacting parts. System engineering is based on system theory, takes the whole system as the research object, considers the overall situation, and uses scientific theories and methods such as operations research, probability and statistics, cybernetics, information theory, management, economics and computer science A discipline that balances and solves problems to achieve the optimal overall cost performance of the system. In the initial stage of system engineering, the information generated by the system is described and recorded in the form of documents, but as the scale and complexity of the system continue to increase, the difficulties faced by this doc...
