A system for determining a group of semiconductor manufacturing process steps with a similar influence on individual semiconductor products. The system generates a first table including time stamps for the individual semiconductor products. The system creates a second table including Q-times based on ...
wait for batch time and wait to match time comprise 90 percent or more of total manufacturing cycle time [23]. When all products and production process parameters can be explicitly considered in capacity planning problem, it will obviously

Through the method, the queue time in the process of manufacturing semiconductor devices can be effectively prolonged, the yield of the product is improved and the process cost is saved.杨涛
The Critical Ratio and Slack Time priority scheduling rules have been applied by a number of firms in computer-based scheduling systems for manufacturing operations. One question in using these rules is whether queue waiting time estimates for individual machines should be used in making scheduling ...

aWhen On time Delivery is < 100%, there should be special transport (break-down to the root-cause and manufacturing processes, which caused the delayed delivery), special transport here includes both to all customers and suppliers. 当准时交付是< 100%时,应该有特别运输(故障对根导致,并且制造过程...
Overview Solutions
Just as manufacturing assembly lines are designed to decouple different complex stages of production, work queues can help decouple different areas of a process allowing each part to operate independently and exchange prioritized inputs and outputs asynchronously....
