Cooperating knowledge-based systems for environmental decision support

摘要

The paper discusses the applicability of cooperating knowledge-based system (CKBS) techniques in environmental decision support. The reasons for using CKBSs are given first. Existing environmental CKBSs are discussed, with special emphasis on a typical example, the Distributed Chemical Emergencies Manager (DCHEM). The methodological framework applied to the building of DCHEM, the knowledge acquisition technique used, and the architecture of the developed system are also described.
