Interpretation system for automated wavelength dispersive X-ray fluorescence spectrometry.

A prototype expert system for automated interpretation of wavelength dispersive X-ray fluorescence spectra is described. The system consists of two main components: a pre-processor (PREXRF) written in BASIC and a knowledge handling part (INFERXRF) that contains the knowledge base and the inference engine implemented in PROLOG. Both systems rely heavily on the theory of fuzzy sets in an attempt to deal with incomplete and uncertain information. The performance of the interpretation system for automated analysis of simulated and measured samples is demonstrated.
