Introduction. The problem of the theoretical foundations of management in
organizational systems, the selection of an alternative to the head of fire
extinguishing is considered, subject to the choice of the decisive direction of combat
operations to extinguish a fire in underground structures of a large area and length
(for example, a subway). A significant issue is the possibility of choosing a decisive
direction, taking into account the ranking of fire extinguishing actions in the case
where the criteria of the current situation may be a variety of possible acceptable
options, and in conditions of reasonable risk. Methods. A comprehensive analysis of the
conditions of justified risk, issues of applicability of the concepts of justified risk
and extreme necessity when organizing fire extinguishing in conditions of uncertainty
and managing a complex organizational system (when extinguishing a fire in underground
structures), as well as factors that arise during each fire in underground structures of
a large area and length was carried out. Results. Indicators of extreme necessity and
justified risk, criteria for reducing the level of risk when conducting combat
operations to extinguish a fire in underground structures were considered, the process
of ranking fire extinguishing actions was formalized and algorithms were developed for
ranking the conditions for choosing a decisive direction, the possibility of assessing
the negative consequences of decisions made, and making management decisions taking into
account the ranking of fire extinguishing actions. Research application field. The
results of the study are aimed at ranking the conditions for choosing the decisive
direction when conducting combat operations to extinguish a fire in underground
structures, in which the use of forces and means at a given time provides the most
effective conditions for performing the main combat mission. The use of the developed
algorithms is relevant not only for analyzing the possible situation during a fire, but
also for scenarios for modeling the control process in an organizational fire
extinguishing system based on the boundary conditions of actions in underground
structures of large area and length. Conclusions. An algorithm for the conditions for
choosing a decisive direction is presented, taking into account the ranking of actions
when extinguishing fires in underground structures. A mathematical description of the
process of ranking actions to extinguish fire in underground structures is given and
indicators of actions within the framework of extreme necessity or reasonable risk are
given. The goal is to scientifically substantiate the development of an algorithm for
ranking the conditions for choosing a direction of action in the event of fires in
underground structures, taking into account the conditions for extinguishing it, and the
integration of an algorithm for ranking the conditions for choosing a decisive direction
when conducting combat operations to extinguish a fire. Keywords: choice; management;
