SITUATIONAL INFORMATION SYSTEM FOR DECISION-MAKING SUPPORT REGARDING INDUSTRY-NATURAL COMPLEXES

摘要

This paper introduces a superstruction upon a geographic information system (GIS) built to create a situational information system (SIS) aimed at comparative static and dynamic analysis of user-formed alternative structures for complex hierarchical spatial objects, namely industry-natural complexes (INCs). The main distinguishing features of SIS are in supporting a domain model open for operative modification, combining different forms of representation for both data and expert knowledge as well as in cognitive processing of situations and development of intelligent coordination procedures and planning of interactions among several decision makers responsible for functioning of INCs components. A hierarchical subject domain conceptual model (SDCM) is used as the heart of SIS to maintain every stage of modelling. This model provides a formal definition of situations occurred within the object under investigation, their categorization and synthesis, thus maintaining multicriteria analysis of decisions on changing/preserving the current INCs structure. Unified processing of data coming from simulation modules of INCs structural components, embedded GIS and expert system (ES) constitutes the main difference between SIS and its prototypes. Such a system ought to become core software for decision making in modern situation centres (SCs) intended for spatial modelling and forecasting at different organisational levels.
