The classification of factors influencing the process of functioning of the information system of cinema network operation is carried out. As a result, the following four categories of factors are established: film, user, cinema, additional service. The category of film determines the factors – film, genre, director, film producer; user category – employee, position; cinema category – time and method of viewing, place of viewing, ticket price; additional service – food, grocery check. Next, ten factors (without a less important factor, the filmmaker) sufficiently characterize the operation of the system. In order to describe the structure of the subject area of the information system, the modeling of the semantic network is done, the nodes of which are the selected factors, and the arcs are the functional relationship between them. To further establish the importance of the action of factors by the method of analysis of hierarchies, a multilevel model of influencing factors is constructed, which are distributed by levels with greater and lesser dominance and a certain set of relations between them. Accordingly, the factors are placed on the following five levels; on the first – genre, director, type of employee, food products; on the second – a film, an employee; third – place of viewing, product receipt; fourth – time and method of viewing; fifth – ticket price. This determines the priority of the factors and establishes the reliability of the degree of influence of factors on the functioning of the information system of the cinema network management system. The next step is to measure the impact of a factor on other factors in a hierarchical sequence, which ultimately leads to the prioritization of factors and consistency with expert judgments – estimates of pairwise comparisons. The numerical values of the weights of the influencing factors are determined, which allows making informed decisions regarding the parameters of the information system of the cinema network management.

Keywords: subject area of information system, classification of factors of influence, multilevel model of influence, weight of factor of influence.
