- 극박 이단 냉간압연 생산공정에서, 작업조건을 분석하기 위한 분석조건을 입력하는 단계(20); 적중률 분석시스템의 데이터베이스에서 입력된 분석조건에 따른 데이터를 선별하는 단계(30); 선별된 데이터로 총 작업코일의 개수를 계수하는 단계(40); 분석 조건별 작업코일의 개수를 계수하는 단계(50); 측정된 압하력과 장력을 선별된 초기 설정값을 대상으로 분석조건별 적중률을 계산하는 단계(60); 분석 조건별 적중률을 각 단계에 속하는 코일의 개수로 계수하고, 각각의 코일의 총 작업코일의 개수로 나누어, 각각의 단계에 속하는 코일의 비율로 계산하여 적중률을 계산하는 단계(70); 적중률의 값이 각각의 설정항목에 대한 적중률 값이 조건별 대비하여 작업 충족 범위에 존재 유무를 판단하는 단계(80); 작업 충족 범위의 유무를 판단하여 만족할 경우 결과를 출력하고 종료하고, 만족하지 못할 경우 다시 분석조건에 따른 데이터를 선별하는 상위 단계로의 이동을 판단하는 단계를 포함하는 것을 특징으로 하는 극박 이단 냉간압연 생산라인에서 생산 데이터의 분석방법.
- 제 1항에 있어서, 적중률 분석은 초기 설정값(압하력과 장력)으로 생산공정상의 측정값(압하력과 장력)을 나눈 후 백분율로 표시하는 것을 특징으로 하는 극박 이단 냉간압연 생산라인에서 생산 데이터의 분석방법.
