| 摘 要： | Introduction In recent years, labor cost in China is continu-ously and significantly increasing across industries.More and more companies, particularly semiconduc-tor companies, are taking strategies to cut labor costwithout impairing normal production. Operator-ma-chine ratio (OMR) denotes the maximum number oftools a laborer can operate. It is a measure of opera-tion efficiency of an operator and one of key factors toensure the competitiveness.The traditional static Excel model[1]involvin… |

| Abstract: | Based on a simulation model of a semiconductor manufacturer, operator-machine ratio (OMR) analysis is made using work study and time study. Through sensitivity analysis, it is found that labor utilization decreases with the increase of lot size.Meanwhile, it is able to identify that the OMR for this company should be improved from 1∶3 to 1∶5. An application result shows that the proposed model can effectively improve the OMR by 33%. |
