Fuzzy risk analysis approach test-case: Lead-free soldering process

The increasing complexity of technological processes has imposed considerable uncertainties and subjectivities in the risk analyses of these processes. The paper integrates the use of fuzzy logic and expert database with FMEA. Application of fuzzy sets theory on FMEA of a technological process. Analysis of the lead-free soldering process is based on fuzzy logic. The proposed fuzzy risk analysis approach is more flexible and more intelligent than the original risk analysis techniques. The paper shows case-study of fuzzy FMEA of a lead-free soldering.
