Ontology models for real time systems

The modern state of information technologies is characterized by permanently increasing level of requirements to operation effectiveness, cost, duration of development and the level of intelligence of information systems (IS). The effective approach to solution of these problems is the usage of ontology models in all stages of IS life cycle. An essential part of modern IS are real time systems (RTS). In the article the mechanisms of processes management which are used in modern RTS and possible aspects of ontology models used for solving problems appearing in different stages of RTS development are analyzed. From the development point of view, RTS requires a specific architectural design stage. This stage uses architectural ontological models which allow implementation of architectural decision support system and mechanisms of architectural knowledge saving and processing. The structure of architectural ontological model is considered, three levels of model maturity are defined. The composition of knowledge to be included into a model kernel is considered. The built-in ontological models in RTS can be used for implementation of the functions connected with realization of cognitive behavior. It is suggested to use presented architectural ontological model as an element of well known and widely used Zachman's framework.
