Time-constrained reasoning and consistency maintenance for real-time knowledge-based systems

Research output: Contribution to journalArticlepeer-review


In recent years large numbers of knowledge-based systems (KBSs) have been developed that take their input directly from plant sensors rather than via human operators. Although such systems have often been termed real-time KBSs, they have had few architectural features specifically designed for time-critical operation or for dealing with dynamic environments. This paper first describes why one of the major features of KBSs, the separation of control information and domain knowledge, poses particular difficulties when the above issues are considered. Subsequent sections discuss the trade-off of solution quality against time and use of consistency maintenance mechanisms as ways of dealing with these problems.
