| dc.description.abstract | Affected by Covid-19 and the US-China trade war in the first half of 2020, the demand of consumer market was not as good as in the past, but Covid-19 spread rapidly, many countries began lock down the city, and some factories were forced to shut down. It affects the entire supply chain seriously, in order to avoid unknown future, major brands and foundries have increased their inventory to reduce the shortage impact. In the second half of 2020, 5G technology market demand increased, distance learning, work at home, drive the trend of semiconductor supply chain booming, and the order has exceeded the capacity load a lot.
Due to Taiwan’s epidemic situation was controlled well, huge orders have been transferred to Taiwan. The production capacity is full, and it has begun to accelerate the purchase of equipment. But in the short time, equipment can’t be ready so quickly, how to increase capacity with limited resources is one of the most important issues for the company.
The study uses the Theory of Constraints to find the bottleneck step, and aims at improving the production efficiency of the bottleneck step to increase the output. Through more than half a year data analysis. Find out the way to decrease the change-over rate, so that the overall equipment effectiveness of the bottleneck step will increase, and the output will also increase. | en_US |
