Knowledge‐enriched Process FMEA Model For Process Planning

Abstract

Most process FMEA systems in the market simply fill out the worksheet/form, and can not effectively express, organize, and utilize process failure knowledge of production process during process planning. This paper proposes a knowledge‐enriched representation model for enhancing process FMEA in process planning. This model can effectively represent the process FMEA knowledge other than specific process failure instances or data. Furthermore, in order to effectively utilize the previous process FMEA knowledge, an algorithm is proposed to calculate the similarity among process failure problems based on “concept distance”. A knowledge‐enriched process FMEA tool has been developed by adopting Web technique so as to provide cooperative process FMEA services for process planner on the Internet or Intranet.
