Methodological Approach to Determining the Priority of Requirements for a Comprehensive Survivability Support System

The modern character of military operations is characterised by an increase in spatial scale, high maneuverability, rapid changes in the operational environment, the need for timely and well-founded decision-making, and the integration of a large number of forces and assets into a unified information and communication space. Against the backdrop of active use of unmanned systems and the transition to multi-domain operations, the survivability of distributed automated organisational control systems for forces and assets becomes a key factor in the effectiveness of military command and control systems. At the same time, the issue of prioritising requirements for a comprehensive survivability support system remains insufficiently addressed in the scientific literature, which complicates the formation of a rational structure for such a system. The aim of the article is to develop one of the possible approaches to determining the priority of requirements for a comprehensive survivability support system, taking into account the uncertainty of combat and electronic warfare environments, as well as the need for adaptive development of distributed automated organisational control systems for forces and assets. A systems approach, the theoretical foundations of graph theory, methods for structuring sets of elements, expert assessment, and the construction of a binary reachability matrix were applied in the study. The procedure includes the formation of an expert group, determination of logical dependencies between requirements, graph construction, and multi-level analysis with the formation of a priority hierarchy. Interdependencies between five key requirements for the comprehensive survivability support system were established: quality, rationality, recoverability, adaptability, and controllability. A priority model was developed, allowing the ranking of requirements by levels of importance. As a result, the following hierarchical structure was determined: first level – quality; second – controllability; third – recoverability; fourth – rationality and adaptability. The proposed approach allows for an objective determination of the key requirements for a comprehensive survivability support system depending on operational conditions and resource constraints. The results can be applied during the design, modernisation, and optimisation of the system structure, as well as in managerial decision-making aimed at enhancing the survivability of distributed automated organisational control systems for forces and assets in modern combat conditions.
