System Man

The Man-Machine System (HMS) is a control system where a person controls a technical device or machine to achieve a specific goal. HMS is the subject of study of such sciences as ergonomics and engineering psychology.

HMS can be presented in various forms, for example, it can be a conveyor line in a factory, robot control, or even computerized process control. In each case, a person controls a machine to achieve certain results.

The Man-Machine system can be described as a single system where man and machine work together to achieve a common goal. However, in practice, the interaction between man and machine can be complex and requires careful study. Ergonomics and engineering psychology help to understand how a person interacts with a machine and what conditions must be created to ensure effective control.

One of the important aspects of the Man-Machine system is safety. When working with machines or other technical devices, it is necessary to consider possible risks and take precautions to protect people from possible injury or damage.

Overall, the Man-Machine system represents an important element of modern industry and technology. It enables people to operate machines and processes more efficiently and safely, helping to grow the economy and improve the quality of life.

System Man and its relevance

The Human system is a complex of technical devices and software that allow a person to control them to achieve certain goals. This system has become popular in recent years due to its efficiency and ease of use. It represents a whole range of technical devices such as smartphones, computers, tablets and other gadgets, allowing people to manage all their needs using one device.

Humanity has always strived to automate production processes and simplify everyday life. It is very important to define the framework of robotization and the processes of introducing artificial intelligence into the modern economy. The elimination of human labor will allow non-developing countries to carry out social reforms and stop lagging behind the economic development of other countries. The “Human” system is one of the important components of the engineering production management system. The role of man in this system is not constant. In some cases, it is completely excluded from this system, being replaced by autoregulators used in the automatic control system (ACS). In this case, the ACS becomes a closed system. An example of such a system is a thermostat that maintains a given temperature in a furnace. People become involved in a regulatory device in cases where it has an input signal of a certain type, when with one indication it is necessary to take measures to counteract one or another deviation, as a result of which the formation of a control action requires additional knowledge and skills. Such limits of human involvement in the regulatory system are quite large. There may be cases when a person is not trusted to even detect input signals through, for example, sensors. However, situations are possible when it is more expedient to let a person into the machine, that is, they exclude some parts of the machine, making it difficult or completely preventing the maintenance of system stability. The very existence of such a possibility presupposes an analysis of the costs and expected benefits of expanding human participation or alienating individual parts of the machine. The peculiarity of the “man-machine” control system is due to the large difference in control objects for its various links, which are further complicated by their large number and hierarchy. The hierarchy of these links, naturally, also has its own boundaries, crossing which is unsafe for human health and the operation of the machine. The transition from one link of a machine to another is always associated with an impact on a person; his reaction should be anticipated. This is necessary in order to make the right decision and not find yourself outside the control of a person. Interesting
