工作現場流程及效率改善-以A餐具洗滌公司為例

Operation Flow and Efficiency Improvement-Case Study the Dishwashing of A Company

摘要


本研究的主要目的是運用工作研究的手法來進行餐具洗滌工作現場流程改善。從工作研究方法中的工廠線圖(flow diagram)、多動作程序圖(Multi-Man-Machine Chart),來綜合檢視流程搬運距離、各個工作站之間的動線、各員工在工作閒置時間與工作總時間,並結合ECRS之IE改善四原則探討減少各種事項的次數、時間及距離,以提高生產效率。本研究透過資料的整理發現個案公司在改善後獲得以下的結果,新工作流程,使總過程時間由原本的59262秒改善為27660秒約節省47%的時間;總體人力由7人減少為4人,約節省43%的人力;總體團隊工作效率則由75%大幅提升為90%。在洗滌動線方面,改善後餐具洗滌工作動線整體移動距離由9610公分減少至7230公分,共減少2380公分,約節省42%移動距離。

The purpose of this study wants to enhance the operation flow in the dishwashing workplace by method of work study. The Study Method has using flow diagram, Multi-Man-Machine Chart to overall Review the flow lines distance and distance of movement between workstations and calculation idle time and work time of each staff in the work process, and using ECRS to decrease useless work item of frequency, flow distance and work time, to achieve enhancement work efficiency. The new Work flow improvement for the Total process time from 59262s to 27660s (Cost Down 47%) , the Total Manpower improve from 7 to 4 (Cost Down 43%), Total work efficiency improve from 75% up to 90% (increase 15%) , Finally on Work Flow Distance improve from 9610cm to 7230cm, Total saving 2380cm.
