A Study on the Decision For the Process Improvement Alternatives to Reduce the Fraction Defective

불량률(不良率) 감소(減少)를 위한 공정개선대안(工程改善對案) 결정(決定)에 관한 연구(硏究)

This study is concerned with the reduction of fraction defective for quality improvement model in manufacturing system. For the methodology, a heuristic method for the selection of alternatives of process improvement is introduced for quality improvement and cost problem subject to cost constraints. This study suggests a model for selecting fraction defective reduction alternatives in multi-stage manufacturing system and a numerical example is presented.
