Research On Production Efficiency Improvement Of D Company Based On The Value Stream Map Analyzing Method

This thesis is focus on the D company efficiency improvement which based on Value Stream Map Analysis,D company is belonged to UK,its product is condom.D company had been in China for 9 years.Since china manufacture cost increased,the margin reduced a lot,they hope to get a revolution to improve this issue.after check some Lean manufacture documentation in and out of china.also the old record and some detail data which from production,quality,purchase,machine maintenance department,hope to get a benefit after these improvement.This thesis is used document analysis,onsite investigation,Value stream map Analysis and latest improvement status.to know the future direction.After check the working time,stock Qty,production lead time.And used Comparison evaluation,Fishbone analysis,to find root cause,to optimize process.reduce lead time,to reduce stock Qty.From Lean manufacture,knew the Value Stream map.Understand Value Stream Map process.after use this tool,to find the manufacture process main issue.the production line balance,production Takt,production plan mode.And design future Value Stream Map.design the whole production improve plan,to increase yield so as to reduce waste,increase machine speed.The Qty is higher per same working time.so as to get efficiency increased.The thesis is divided 6 sections,section 1 is the background.section 2 is Lean manufacture and value stream method introduction.Section 3 is D company manufacture system status.section 4 is D company improvement study.Section 5 is the improvement design of process.the last Section is the summary and the study shortage...
