Implementation of Model-driven Complex System Engineering Development System
This paper summarizes the related technologies of model-driven complex system engineering development system and establishes a framework for the development system. Then, expounds the implementation process of the development system in detail and emphasizes the key path points of how to achieve the model-driven system research and development capability. Finally, the author puts forward two suggestions for the application and promotion of the development system. Introduction Since the 1960s, system engineering has become the main method to guarantee system development of national defense field such as aviation and space [1] , while, as the complexity and the cross-domain coupling of systems increasing, rapid changes in external demand and situation have higher requirements in efficiency, quality and innovation capabilities of systems development. Disadvantages of traditional systems engineering method which using text as the main information carrier become more and more obvious in system development: 1) Capturing requirements inaccurately; 2) Changing and tracing the source of Information is difficult; 3) Controlling progress, costs and risks of system development is difficult. To solve the problem of complex system development, the European industry proposed the concept of model-based system development and advocated that the text should be replaced by the models as the main information carrier and driving the whole process of complex system development. As the new round of industrial revolution sweeping the whole world, China is promoting the deep integration of information technology and industrial technology [2] . These theories and techniques, such as Industrial Internet, Model Based Definition, Model Based Systems Engineering, Cyber-Physical Systems, CAD/CAE, Digital Thread, Digital Twin have created a powerful external environment for the “model-driven” development of complex systems engineering. In this context, this paper have studied the implementation process of the model-driven complex system engineering system systematically and put forward two suggestions for the application and promotion of the development system. Overview of Relevant Technologies Model Based Definition The core idea of Model Based Definition [3] (MBD) is to express the product structure, shape, size, process and manufacturing information through 3D model. After the emergence of CAD technology, 2D drawings have become the main basis for product designing and manufacturing, while 3D model is an auxiliary reference. The emergence of MBD technology integrates the design information and product manufacturing information into a three-dimensional digital model perfectly, which help to
