Problems solved by technology

[0011] (1) It is necessary to explain all the system requirements at one time, but in actual application, the system requirements are constantly revised and increased, which leads to the development of the aircraft airborne system to become quite inefficient
[0012] (2) On the basis of explaining all system requirements at one time, test cases also need to be proposed simultaneously. Once system requirements change or problems occur in the verification process, test cases also need to be redefined, which increases the workload and the development cycle is quite long
[0013] (3) Professional teams have unclear division of labor and low work efficiency

specific Embodiment 1

[0076] The technical problem to be solved by the present invention is: on the basis of the traditional MBSE development process, considering the problems of imperfect requirements and frequent changes of requirements, combined with the idea of ​​agile system engineering, the development process of MBSE is improved. In the three stages of MBSE R&D process requirement analysis, function analysis and architecture design, the model is combined with the agile development method. According to the implementation of actual engineering projects, design and planning are carried out, and small cycle rapid iterations are added in engineering practice to reduce the large iterations of the entire project. The model is tested during the system requirements definition and architecture design phase, in order to discover requirements problems as early as possible and form a reasonable architecture design idea.

specific Embodiment 2

[0108] This embodiment takes the navigation system of a certain model as an example, and illustrates the implementation process of this method in the navigation system design from the five stages of determining stakeholder requirements, requirement analysis, function analysis, architecture analysis, and architecture design.

[0109] In the design of the navigation system, firstly, information is collected from various stakeholders of the navigation system, and the needs of the stakeholders are sorted out, and the traceability relationship between the needs of the stakeholders and the standard specification is established; secondly, the needs of the stakeholders are transformed into System requirements, and define system use cases according to system functional requirements, carry out use case planning, and determine the priority of navigation system use case development; then enter the function analysis incremental iterative development, and use SysML activity diagrams, sequence...

Abstract

The invention discloses an aMBSE method suitable for aircraft airborne system architecture design, and the method comprises the steps: converting the demands of stakeholders into system demands, defining system cases, and carrying out the case planning; translating the confirmed use case into an executable black box model, and verifying the model and related system requirements through dynamic behavior simulation of the model; providing a series of alternative schemes meeting requirements for system requirements, and seeking an optimal architecture scheme; gradually expanding a system-level black box model for function analysis into a subsystem-level white box model, and integrating mutually independent subsystems into a complete system architecture in an incremental iteration mode. Smalliteration is added in the system development process, large iteration is reduced, the model is tested in the early stage of design, a reasonable architecture design thought is determined, problems inearly-stage design are prevented from being brought into the verification stage, the complexity of system design is reduced, and the problem of demand change in system engineering is effectively solved.

Description

technical field [0001] The present invention relates to the technical field of architecture design of systems engineering, in particular to an aMBSE method suitable for aircraft onboard system architecture design. Background technique [0002] With the rapid development of my country's aviation industry, the development method of aviation products has changed from reverse imitation to independent innovation, and the demand for new types of national defense and military and civil aircraft systems is increasing. The scale and complexity of aircraft systems are getting higher and higher, especially the emergence of interdisciplinary and interdisciplinary systems, making it difficult for traditional Text-Based System Engineering (TSE) to meet the development requirements of complex systems at this stage. [0003] Currently, modern systems engineering is undergoing a paradigm shift from document-based to model-based. In this context, in 2007, the International Council on Systems...
