The article presents a model of the processes of one of the Bulgarian force-management subsystems – the acquisition system. The modeling approach adopted is architecture-oriented, which means that the processes are represented ac­cording to their sub-processes or phases and activities and the connections in terms of information exchanged between them. The modeling framework selected for this purpose is the widely accepted in NATO and partner countries DODAF (Depart­ment of Defense Modeling Framework). The authors provide a brief discussion of the model and some recommendations for improvement of the process of acquisi­tion management.
