The work presents a model of the organizations' interaction in the framework of the regional scientific-educational cluster, based on the cost approach. When using the hierarchical structure of the cost management system, a new classification of cluster interactions and the clusters themselves was formed, which takes into account not only economic, but also institutional factors. In particular, the model of cluster interactions takes into account the key areas of the organization competence, playing a significant role in enhancing the competitiveness of educational institutions in the post-industrial economy.

However, the modeling of cluster schemes is not paid sufficient attention to: the researchers in the field of clustering focus mainly on sectoral and regional aspects. At the same time, the post-industrial economic development requires a new view on the nature of clusters. In the present work, a cluster is considered on the basis of the concept of business value management and institutional approach.The work models organizations' interaction in the framework of the regional scientific-educational cluster 1 , based on the cost approach.Starting with the famous works by M. Porter (M.E. Porter, 1986), many publications were devoted to the modeling of clusters. Many of them are based on the "competitiveness diamond" by M. Porter. Thus, the work by I.R. Ferova ( , 2005) describes the educational model of local industrial clusters based on "competitiveness diamond" by M. Porter, including the following diamond-forming components:
