FUZZY-MULTIPLE IT CLUSTER MODEL (ON THE EXAMPLE OF THE ROSTOV REGION) BASED ON THE MODIFIED LEONTIEV MODEL AND OPEN DATA SOURCES
The structure of the cluster of information and communication technologies (ICT cluster) of the Rostov region, created in 2015, is considered. It is noted that the cluster development priorities include the organizational development of the cluster and the strengthening of cooperation ties between the participants (interaction potential); development of innovation potential and the research and development sector; development of production potential and expansion of the market share of products and services of cluster members; development of human resources; building a common brand and increasing cluster awareness (marketing potential); development of relations with authorities (management potential). A mathematical formalization of intra-cluster interactions of structural units of a cluster, leading to a change in the potentials of both its whole and individual enterprises, as well as its external interactions, is proposed. For this purpose, it is proposed to use a modified Leontief balance model, the input parameters of which are obtained on the basis of open data sources, as well as their aggregation and fuzzification based on the theory of fuzzy sets.
