The aim of this paper is to present research into the business models of enterprises cooperating in a distribution network of metallurgic products in the context of knowledge management for the needs of strengthening the resilience of supply chains. Supply chains contain links which are crucial for building their resilience. These links are defined as network flagship enterprises. The research was aimed at designing a concept of a knowledge management system concerning knowledge on disruptions in material flows. We proposed an original methodology of appointing the organization attributes which take the role of a flagship enterprise. The concept of the knowledge management system concerning knowledge on disruptions in material flows is dedicated to this type of organizations which have predispositions to implement such solutions in a distribution network. The concept of a knowledge management system takes into account the stage of identification and acquisition of knowledge on disruptions, including their measurement and identification of zones of strengthening disruptions, the stage of processing and analysing knowledge and its utilization as well as making decisions oriented on strengthening the resilience of supply chains. The research is carried out in two stages: the stage of identification of attributes of flagship enterprises in distribution networks of metallurgic products and the stage of designing a concept of a knowledge management system concerning knowledge on disruptions in material flows. In order to fulfil the first stage of the study, the researchers designed questionnaires and carried out deepened and structured interviews. A value added, enriching the management theory is conceptualisation of the knowledge management system concerning knowledge on disruptions in material flows and identification of attributes of the business model of flagship enterprises in distribution networks of metallurgic products. The proposed concepts: the identification of attributes of flagship enterprises and the measurement of disruptions in material flows were verified in the distribution sector of metallurgic products. The organizations where the measurement of disruptions in material flows was conducted show interest with the knowledge management system concerning knowledge on disruptions in material flows.
