Abstract

En 中文

• Real medoids convert WWTP records into observed benchmark regimes. • ANP captures interdependencies beyond hierarchical AHP weighting. • RBF propagation extends medoid priorities to daily PI-GAP diagnosis. • Global-local PI-GAP distinguishes regime limits from daily underperformance. • Rule-based classes guide compliance, energy and nitrification checks.
