Аннотация:The modern production of weapons, military and special equipment is characterized by a high level of materialand science intensity, the involvement of a large number of scientific and industrial organizations in theproduction process, the geographical remoteness of enterprises from each other, which requires the improvementof existing management mechanisms. External political instability as well as the ongoing change oftechnological structures in the economy also complicate the production activities of enterprises of the defenseindustry. The article analyzes the problematic issues of managing the cooperative interaction between defenseindustry enterprises, caused by the development of forms of inter-factory cooperation in the manufacture ofweapons, military and special equipment, and also identifies guidelines that make it possible to effectively planand coordinate the production activities of all actors involved in the implementation of the State Defense Order.As part of the study, a comparative analysis of the functionality of automated production process managementsystems used by defense industry enterprises has been carried out, which made it possible to identify a list ofcooperation management tasks not covered by existing systems. Based on the results of the study, an automatedinformation system for managing inter-factory cooperation has been proposed, the implementation of which willcreate a single information and analytical space for all participants in the manufacture of samples of weapons,military and special equipment. The article presents a conceptual scheme of this system, describes itsfunctionality and main users. The structure of an automated management system for inter-factory cooperation isdescribed, which consists of six modules: defense industry enterprises logistics, planning the production ofsamples of weapons, military and special equipment, defense industry enterprises’ production capacitymanagement, contracting management, normative reference data, the integration of the system with ERP- andPLM-systems of enterprises and departmental information systems. The article outlines the practical significanceof the proposed digital management tool, describes the management tasks solved on its basis, and the expectedeffects of its implementation in the defense industry.
