Explanation of system engineering terms

System engineering is a scientific method to analyze and study the components, organizational structure, information flow and control mechanism of the system in order to achieve the best purpose of the system. It uses various organization and management techniques to make the relationship between the whole and parts of the system coordinate and cooperate with each other, and realize the optimal operation of the whole. System engineering is different from the general traditional engineering, and its research object is not limited to specific engineering objects, but any kind of system. It is an interdisciplinary frontier subject developed on the basis of modern science and technology.

main feature

The main features of the system engineering method are as follows: 1. Analyze the research object as a whole, and analyze the interrelations and mutual constraints among all parts in the whole, so that all parts in the whole can coordinate with each other and obey the requirements of overall optimization; In the analysis of local problems, from the need of overall coordination, choose the best scheme and comprehensively evaluate the effect of the system; Second, comprehensive use of various scientific management techniques and methods, combining qualitative analysis with quantitative analysis; Thirdly, analyze the external environment and changing rules of the system, analyze their influence on the system, and make the system adapt to the changes of the external environment.

The difference between system engineering and general engineering technology

The difference between systems engineering and general engineering technology lies in that systems engineering not only studies material systems, but also studies non-material systems, such as education, culture, news and publicity systems, which are widely used; The general engineering technology is based on the concrete material system. System engineering treats the system as a whole. Based on system theory, cybernetics and information theory, there should be various professional theories of system engineering; General engineering technology mainly deals with specific technical categories, focusing on professional theories. System engineer is a system engineer, a customer, a staff officer, an assistant to decision makers and serves the society; Ordinary engineers are professional and technical personnel. They have different professional quality requirements.
