Concept Formation in WWTP by Means of Classification Techniques: ACompared Study

摘要: Although activated sludge process is a very widely used biological in wastewater treatment plants (WWTP), and there are properly functioning control loops such as that of dissolved oxygen, practice, this type plant requires major time investment on the part operator, involving many manual operations. Treatment work well most time, long not unforeseen occurrences. Normal operating situations (generally similar to design conditions) can be treated mathematically by using efficient algorithms. However, which system cannot manage plant, only efficiently managed thanks operator‘s experience. This case knowledge-based may useful. One difficulties inherent development obtain knowledge base (i.e., {\it knowledge\ acquisition}), specially when dealing with wide, complicated ill-structured} field. Among aims those show how semi-automatic acquisition tools could help human experts organize their about domain also, compare power different approaches acquisition} same database. In paper presented results obtained from applying two classification techniques knowledge-bases for management an process.
