What is systems engineering and what are the professional engineering systems

Systems engineering is an interdisciplinary approach to the realization of a product. Through it, you are able to understand each of your products as a whole and better structure your product planning.

Development, manufacturing and maintenance processes. Businesses use systems engineering to create interactions between requirements, subsystems, constraints, and parts of a product.

Conduct modeling analyses, and make optimizations and trade-offs throughout the product lifecycle.

Make important decisions. Throughout the life cycle, systems engineers.

Leverage a variety of models and tools to capture, organize, prioritize, deliver, and manage system information. For example, through QFD, House of Quality, Six Sigma.

Design (DFSS), TRIZ, and other technologies, systems engineering captures and prioritizes customer requirements at the front end; Then, functional modeling, object-oriented approaches, state diagrams, etc., are used to evaluate alternatives and go down to functional and physical divisions.

Systems engineering is a general term for a large category of engineering technologies that use systems thinking to directly transform the objective world. A system is an organic whole with a certain function composed of several components that are interrelated, mutually restrictive and interact with each other. People's understanding of the system, that is, the idea of the system, is the best in social practice.

In the long-term social practice, people have gradually formed the idea of linking the various components of things and analyzing and synthesizing them from a holistic perspective, that is, system thinking. Systems thinking has existed since ancient times, but the birth of systems engineering has been in the past 40 years. With the rapid development of science and technology and the continuous expansion of production scale, there is an urgent need to develop a technology that can effectively organize and manage the planning, research, design, manufacturing, testing and use of complex systems, that is, systems engineering.

Systems engineering is the science of system optimization. It was officially named around 1957. The system was formed around 1960.

It is a highly comprehensive management engineering technology, involving applied mathematics (such as optimization methods, probability theory, network theory, etc.), basic theories (such as information theory, cybernetics, reliability theory, etc.), system technology (such as system simulation, communication systems, etc.), as well as various disciplines such as economics, management, sociology, psychology, etc. The main task of systems engineering is to link the basic ideas, theories, strategies, and methods in the natural sciences and social sciences from horizontal aspects according to the needs of overall coordination, and to apply modern mathematics and computer tools to analyze and study the functions of the system, such as the constituent elements, organizational structure, information exchange, and automatic control, so as to achieve the goals of optimal design, optimal control, and optimal management. Systems engineering can be roughly divided into three stages: system development, system manufacturing and system application, and each stage can be divided into a number of small stages or steps.

The basic methods of systems engineering are: system analysis, system design, and comprehensive evaluation of the system (performance, cost, time, etc.). The application of systems engineering has become more and more extensive, and by the 70s of the 20th century, it has developed into many branches, such as management system engineering, logistics system engineering, administrative system engineering, scientific research system engineering, environmental system engineering, military system engineering, etc.

Systems engineering is a branch of systems science, which is actually the practical application of systems science. It can be used in all aspects of the system, including human society, ecological environment, natural phenomena, organization and management, such as environmental pollution, population growth, traffic accidents, arms race, chemical processes, information networks, etc. Systems engineering is a theory and method that takes large and complex systems as the research object and designs, develops, manages and controls them according to a certain purpose, in order to achieve the best overall effect.

Systems engineering is an engineering technology, but systems engineering is a major engineering technology category that includes many types of engineering technology, involving a wide range, not only using natural sciences such as mathematics, physics, chemistry, biology, etc., but also using sociology, psychology, economics, medicine and other disciplines related to people's thoughts, behaviors, abilities, etc. The basic theories required for systems engineering include operations research, cybernetics, information theory, management science, etc.

Architectural specialization in the professional engineering system.

Exploration and quality inspection. There are also structural and drawing majors and so on.

Systems engineering for projects is organizational management.

Planning, research, design, manufacturing, testing and operation of large-scale engineering projects.

According to different engineering projects, engineering systems engineering can be divided into many sub-disciplines, such as aerospace system engineering, missile system engineering, and nuclear.

Systems Engineering, Aircraft Systems Engineering, Electronic Systems Engineering, etc.

Their common professional theoretical basis is engineering design, because the overall design of large-scale engineering projects requires the use of engineering design knowledge, and at the same time, it requires corresponding professional engineering and technical knowledge.

The basic problem faced by large-scale engineering projects is how to gradually turn the relatively general initial development requirements into the specific work of thousands of participants in the development tasks, and how to finally integrate these tasks into a technically reasonable, economically cost-effective, short-term development cycle, and a practical system that can operate in a coordinated manner, and how to make this system an effective part of the larger system to which it is subordinate.

Such a complex task of overall coordination cannot be done by a single person. This requires a member of the congregation or an organization to take the place of the former chief designer and coordinate and direct this large-scale social labor. In China, such an organization is called the General Design Department.

The overall design department is composed of scientific and technical personnel in all aspects, and is led by experts with a wide range of knowledge.

The overall design department designs the overall system, the overall scheme of the project and the technical way to realize it. The overall design department is generally not responsible for the design of specific components. The overall design department regards the system as an integral part of the larger system to which it belongs, and all its technical requirements for the volt difference are first considered from the point of view of achieving the technical coordination of this larger system.

Systems engineering is a scientific method for analyzing and studying the components, organizational structure, information flow, and control mechanism of a system.

It uses various organization and management techniques to coordinate and cooperate with the whole and parts of the system to achieve the optimal operation of the whole. Systems engineering is different from traditional engineering in that it is not limited to specific engineering material objects, but any kind of system. It is an interdisciplinary marginal discipline developed on the basis of modern science and technology.

In addition, starting from the concept of system, the optimal integrated organization, management, technology and method of the whole system are obtained by the optimization method. Systems engineering is a scientific method for organizing and managing the planning, research, design, manufacturing, testing and use of 'code pure systems', and is a scientific method of universal significance for all 'systems'.

Systems engineering includes the following principles

1.Systems thinking: Systems engineering focuses on holistic thinking, regards the system as a whole, and realizes system optimization and coordination by analyzing and designing the relationships and interactions between various subsystems.

2.Risk management: In systems engineering, risk management is emphasized, and measures are taken to reduce the probability of risk occurrence and ensure the safety, reliability and stability of the system by analyzing and evaluating the potential risks in the system.
