The most progressive and promising model of spatial organization of food markets of the North Caucasus Russian Theatre is a cluster model. In the proposed methodology of the process approach to develop a structural model of agro-food cluster in the NORTH is cluster analysis. The regional food market as a single system, which combines production, marketing and consumption of foods with a specific hierarchy, is characterized by different relationships and proportions between its components and is an important an indicator of a country's economic development, achieving food security. Disclosure of potential in a market system, its effective use, taking into account regional particularities and specificities of the economy, improvement of the spatial organization and improving the efficiency of such a complex system as the regional food market is impossible without knowledge of its essence, principles of formation and operation. In this connection there was a need to develop modern methods of research, evaluation, analysis, improvement of structure and functional organisation of the regional food markets as an important factor for the socio-economic development the country. The novelty of the research lies in the fact that the clustering of agribusiness implemented taking into account the peculiarities of regional AIC on the basis of strategic management zones: industrial, conventional and organic. To determine the effectiveness of the cluster algorithm of its evaluation, which is based on the criteria of usefulness and survival in the conditions of the cluster in the region, which are defined using evaluation scales and weights the main factors utility and survival in the cluster.
