System architecture construction method

Abstract

The invention discloses a system architecture construction method and belongs to the field of system engineering. On the basis of an N2 diagram of a system architecture, an architecture allocation sheet is constructed, the allocation condition of multiple physical devices in any architecture scheme is represented, then all physical interface relations of the physical devices in the architecture allocation sheet when the physical device realizes corresponding functions are listed, and a second N2 diagram with physical interface relations is constructed according to the physical interface relations; finally, multiple architecture schemes with the physical interface relation similarity up to the threshold under different architecture schemes are found out from the second N2 diagram, the same physical device with different indexes under the multiple architecture schemes is found out from the architecture allocation sheet, a spider diagram of the physical device is constructed, and the optimal system architecture scheme is selected according to the spider diagram. With the adoption of the method, the functional requirement of the system is unfolded in a hierarchy form, ordinal relations and data streams among functions are displayed, and the optimal architecture scheme can be selected.

Description

technical field [0001] The invention belongs to the field of system engineering, and in particular relates to a method for constructing a system architecture. Background technique [0002] The system architecture is to realize the technical framework of the determined requirements, make a plan, and use a complete set of complete tools to complete the task in the planned steps. [0003] In the prior art, system engineering methodology and related tools are generally used for architecture design, such as UML or SysML visualization tools, to analyze and describe the system from different perspectives, for example, UML uses use case diagrams to describe system functions from the perspective of users, which is A model diagram of system functionality as observed by the user. A class diagram describes the static structure of classes in the system. The sequence diagram represents the dynamic cooperative relationship between objects, emphasizes the order in which messages are sent ...

Problems solved by technology

Both UML and SysML analyze the system from multiple perspectives through different model diagrams. First, the system is regarded as a black box, starting from the external relationship, multi-dimensional analysis of the system, and finally the system is transformed from a black box to a white box for forward design. , this design method analyzes the system from the perspectives of system boundaries, external stakeholders, status, etc. This kind of analysis is relatively comprehensive, and it is not easy to miss requirements, especially when the user requirements in the early stage are not very clear, the system architecture can be obtained through layer-by-layer analysis , the disadvantage is that it is difficult to get started and requires professional training. For the multi-person collaborative work mode of complex systems, multiple people draw multiple system models for the same system. Even if the system model design standard is customized, there is still poor matching between the models. , Difficulty in docking, unusable models, etc.
