The urgency of the problem, oriented to the study of the influence of technological parameters, the relations between which is formalized by the means of semantic networks, taking into account linguistic terms, is attached to the corresponding factors, which will serve as the basis for ranking factors and synthesizing a multilevel model of their priority influence on the quality of the printing process. The problem is solved at the informational level, since the research is carried out on the basis of models, the main paradigm of which is the advantages between the factors in their pairwise comparison, taking into account the connections given by the semantic network. This principle is more versatile, since it provides the application of a common methodology for factors that are quantified by numerical characteristics, and covers weakly formalized requirements described in the natural language.
Following the methodology adopted in the article for the solution of such problems, the initial stage for each step of the production of printed matter is to distinguish the most important ones from the general list of a certain set of factors from the point of view of experts. In this study, this procedure refers to the factors of the printing process. With the participation of experts, they include: a type of printing machine; a type of printing plate; a type of deck; characteristics of paper and ink; moisturizing solution; deformation of the deckel in the contact area with the printing plate and in the area of the printing contact; printing speed.
As a result of the study, a formal representation of the set of factors in the printing process has been carried out. A semantic network for graphic and linguistic reproduction of links between factors influencing the quality of book printing has been projected. Using the constructs of the language of predicates and linguistic terms, it has been identified at the formal level of the connection between the factors of book printing. The description provides only direct influences that are sufficient to understand the substance of the relationships. Based on the hierarchy modeling method, the priorities of the factors have been determined, for which the matrix of pairwise comparisons has been constructed and processed. A multilevel model of the priority influence of factors on the quality of the printing process has been synthesized.
