Abstract:

The traditional methods based on documents are confronted with a variety of problems,such as long periods of development,difficult verification of requirement and complex procedure of alteration.To address the challenges in the development of avionics communication system,this paper proposes a model-based systems engineering (MBSE) method.Based on the dominant Harmony method in the aerospace field,the requirement model,function model and physical structure model are built respectively through the requirement analysis,function analysis and design synthesis.This method not only ensures the traceability of data,but also improves the design efficiency and reduces the design risk of the project,hence providing references for the further utilization in the avionics system.
