Abstract
In times of information flooding us from everywhere and in an environment of increasingly complex and difficult to understand systems that our forces face in the operational environment, there is a need for alternative approaches to analyzing the environment and its participants. This approach meets key requirements and provides new and in-depth knowledge of systems. Network analysis is an approach based on graph theory that is applicable to the analysis of any system or process with a network structure. The network analysis toolkit is suitable for highlighting “important” players or elements in complex networks invisible at first glance, according to various criteria set in the term “important”.
