RULE-BASED EXPERT SYSTEMS IN THE CONTROL OF WASTE-WATER TREATMENT SYSTEMS

Rule-based expert systems create a low-cost solution to master all empirical knowledge available in existing wastewater treatment plants. Currently there exists no universal model for processes of biological wastewater treatment, while existing data records and human experience form, however, a valuable knowledge base for an enhanced understanding of process interrelations. In spite of the natural ambiguity of human reasoning and expression, final control policy can, nevertheless, be efficiently translated into on-line automation.
