Man-Machine-Environment System Analyses and Impact of Environment Factors to Productivity and Health of Employees

Abstract

In the research literature, the work environment is often characterized by physical, chemical, biological, and cultural complex factors that affect an employee at the workplace. The work environment is part of the "man-machineenvironment" system. In this system, "man" refers to the subject in the workplace (e.g operators, decision-makers), "machine" is the general name for any object controlled by man (tools, machines, computers), and "environment" describes the specific working conditions under which man and machine interact (temperature, noise, vibration, lighting, radiation, chemicals, hazardous gases etc.). The working environment creates a wider or narrower set of factors which are affecting this system. The role of this whole system is to create optimum conditions for achieving the desired results. The three main goals to optimize are to ensure safety, high efficiency, productivity and economy of "man-machineenvironment" system. Man-machine-environment system engineering is a new developing synthesis frontier science. It analyses three factors for man, machine and environment of the system and the relationship among them to make the system become "safety, and productivity. For problem-solving in this system, the physical factors are very important and may represent a significant risk for employees. These factors affect the human senses, burden the nervous system and can negatively affect overall health and cause stress. Factors can be external (from the environment, psychological, or social situations) or internal (illness). Examination and assessment of working conditions for their impact on employees are challenging, time-consuming and it is essential to do it regularly to achieve reliable results. This paper relates by comparing the results from previous and current assessments to capture developmental tendency, identify progress or regress and subsequently decide on the next steps.

A Novel Methodology Analyzing the Influence of Micro-Stresses on Human-Centric Environments

“…The requirements for computer simulators and the principles of their construction are considered in [19], the role of interactive simulators for personnel training is also shown, and the stages of creating educational electronic products, which include computer simulators, are defined. The article [20] compares the results of an analysis of the development of man-machine systems and previous and current evaluations to identify trends in this development to decide on the next steps. Based on an analysis of the professional activity of a technological process operator in [21], a model of the formation of operator skills in com-puter training is built.…”
