Expert method, which is the network method requires the subsequent stages of subjective measures based on expert opinion. It can also be used in the ergonomics analysis of complex production systems for weighting ergonomic criteria. One of the most important steps in the network method, is to determine the interactions and links between the ergonomics affect the level of production systems. Then, with the help of experts evaluated the relations and interactions between the test nature of an impact on the phenomenon (negative or positive), as well as their type (bi-directional or unidirectional) and intensity. In addition, the time horizon is evaluated influences on the point under consideration (from short-term to long-term). All the elements are the basis for the creation of a matrix of influence within which specifies the factors active, passive, lazy critical and there is a map detailing the intensity factors led and guided. Actions based on subjective expert opinion may be subject to high volatility resulting from the knowledge and experience of experts. Therefore proposes the concept of the individual steps of the method of quantification of the network and to lay the foundation of an expert system, which depends less on the level of expertise.
