Abstract
<jats:p>The paper develops a formalized system model of an autonomous marine platform (AMP) as a multi-connected dynamic structure with quantified intersystem impacts. The methodological basis of the study is a systematic approach to the analysis of AMP as a multi-level dynamic system with internal cause-and-effect relationships. The application of the proposed approach provides a transition from a qualitative description of the structure of an autonomous marine platform to its formalized model, suitable for further analysis of the stability and manageability of AMP, assessment of the integral efficiency of functioning and optimization of operating modes of autonomous marine systems. A combination of structural decomposition methods, matrix modeling, and oriented graph theory is used to formalize intersystem interactions. The autonomous marine platform is presented in the form of four interacting subsystems: energy, motor, information and diagnostic and management, for which state vectors are defined and a generalized state space is formed. Intersystem interactions are formalized in the form of a matrix of influences and a weighted oriented graph, which made it possible to quantify the structural role of each subsystem. This approach allows us to implement adaptive management, in which decisions are made not in isolation for individual modules, but taking into account their system interaction, which creates the basis for building a digital double of the platform and further implementing algorithms for optimizing and predicting the technical condition in real time. An indicator of the total initial impact is introduced, which is used to determine the dominant subsystem in the structure of interactions. The results of the analysis confirm the central role of the management subsystem in the formation of a closed adaptive control loop and ensuring the integral efficiency of the autonomous marine platform in conditions of environmental uncertainty.</jats:p>
