Based on the analysis of management practices and the context of operational decision-making in a number of commercial and state organizations, the concept of mutual perception of people occupying positions in the hierarchical structure is formulated. The potential dynamics of the values of the personal and social aspects of perceptions is established. The specification of a simulation model of organizational behavior in a hierarchy is given. Decisions on belonging to organizational units (groups) are made by persons based on values of mutual perceptions. The driving force of individual and group behavior is the dynamics of mutual perceptions. The specification includes a list of model agents and their main attributes, the methods used, the scheme of information flows and the plan for the simulation experiment. The practical value of the study is that the results of a simulation experiment will allow us to develop practical recommendations for corporate HR and security services.
