Expanding the position of accounting for the investment product in the process of production activity
The logistics cluster is a long-term equal partnership of legally separate enterprises by combining their key competencies, which allows moving material and related flows within the framework of logistics activities. Clusters are mesological systems that unite value chains, taking into account the flow processes of interdependent and supporting sectors of the economy and institutions related to these sectors. The logistics cluster, in turn, is the economic formation of the leader system, which ensures the competitiveness of key participants and the system as a whole. The obtained results of hierarchical cluster analysis, based on economic indicators collected over eight years, cannot be recommended for use due to the peculiarities of the analyzed data and the fundamentally significant drawback of the above method is the absence of a single mathematically rigorously proven criterion for the optimal distribution ("cut") of the dendrogram into clusters when their number is not known in advance. In addition, agglomerative clustering algorithms (except for the single link method) include in clusters objects grouped around the selected center of the cluster, due to which clusters are formed in the form of hyperspheres, and the cluster structure changes depending on the radius of the circle, which does not allow to unambiguously solve the problem.
