Silk cocoon grading by fuzzy expert systems

Abstract: This chapter discusses using an intelligent fuzzy expert system as a grading method for silk cocoon selection problems. It begins by reviewing the need for an expert quality system for cocoon assessment and proposes fuzzy logic as the best approach for this. The chapter then offers a brief outline of fuzzy logic and the development of a fuzzy expert system for cocoon grading. The significance of shell ratio (%), defective cocoon (%) and cocoon size in governing the quality of cocoons has meant that these are the three main quality parameters used for cocoon grading. This provides a good flexibility in reflecting the expectations and visual grading into the results.
