Disaster management increasingly depends on various Various models have been proposed for modeling of information systems, such as modeling and simulation systems or systems of systems in general or disaster management in visualization and geographical information systems, to support particular. DeLaurentis [1] defines four general categories (or decision makers at various stages of a disaster. The conceptual aspects) including resources, operations, economics, and modeling of the domain for such systems is challenging, especially pi r s o s a t fo IYS ily~~~~~p olicy for systems Of systems and then considers levels of for IT developers new to the field In this paper we present three ontologies that reflect three diferent views to a sub domain of organizations withi each category. The lowest level network disaster management at different levels ofgranularity. We compare in each category consists of basic elements in that category the ontologies and discuss how a high-level model can separate and the consequent levels consist of the networks of lower concerns of various stakeholders into logical layers of abstraction, level networks (network of networks). The categories and facilitate understanding of the domain, and inform development of levels can be extended according to the circumstance. Elvarious application systems. Diraby [2] proposes a common framework for development of all infrastructure systems and interoperability between Keywords -disaster management, conceptual modeling, ontology, them. The main concepts of this framework are products, system modeling processes, stakeholders, sustainability constraints, and legal constraints. Min et al. [3] use the system dynamic model to
