Abstract: Crisis Management Systems are evolving from human organizations making use of information systems towards three-layered networks of human actors, artificial agents and traditional information systems. In order to understand the qualities of such complex “COMBINED” systems a joint effort of the sciences of human and artificial systems is required. To ensure practical results, research efforts should anticipate engineering efforts by providing architectural mechanisms and patterns associated with the qualities and capabilities of Combined Systems as a whole. © Proceedings ISCRAM 2004.
