On-line Modelling and Assessment of the State of Technosphere and Environment Objects based on Monitoring Data.

This paper presents an approach of operational control of the state of technosphere and environment objects based on the integration of Data Warehouse, OLAP and Expert systems technologies. It looks at the structure of data warehouse that provides consolidation and storage of monitoring data. There is a description of OLAP-models that provide a multidimensional analysis of monitoring data and dynamic analysis of principal parameters of controlled objects. The authors suggest some criteria of emergency risk assessment using expert knowledge about danger levels. It is demonstrated now some of the proposed solutions could be adopted in territorial decision making support systems. On-line control allows authorities to detect threat, prevent emergencies and ensure a comprehensive safety. [ABSTRACT FROM AUTHOR]
