The defence system is decomposed into a number of sectors. A direct method of coordination is used at the upper level, while the sectors use a discrete-time event-based model and the description of uncertainty by multiple scenarios of an attack. The resulting problems are solved using linear programming. A comparison of two coordination strategies for realistic attack scenarios and an analysis of effectiveness are provided.}, type={artykuł}, title={Periodic coordination in hierarchical air defence systems}, keywords={Missile Defence, hierarchical systems, coordination, decision support systems}, }
