What is AI?
Artificial intelligence(AI) is the intelligence of machines and the branch of computer science that aims to create it.
Al text books define the field as "the study and design of intelligent agents“
John McCarthy, who coined the term in 1956, defines it as "the science and engineering of making intelligent machines
History of AI

Machine)과 머신 간의 통신 속도가 달라지는 것을 측정하여 거리 별 통신 성능을 평가를 해보려 했었다. 그렇게 며칠간 시도를 해보았으나 ns2의 구조상 거리 별로 통신 성능이 달리지는 것을 ns2로는 구현하기 힘들었다. 그래서 구현하기 힘든 ns2보다는 실제 환경에서 어떤 성능이 나오는지 알 수 있는 실
machine breakdowns can be reduced.
Second, PM guarantees better conservation of assets and increased expectancy of facilities' life, thereby PM can eliminate premature replacement of machinery and equipment.
Third, PM can reduce overtime costs, and guarantee more economical using of maintenance workers by scheduled working.
Fourth, PM reduces the cost of repairs by reducing secondary failure
errors in progress: 2000PPM and errors in outward flow: zero), reduce a cost of producing. Strategy of development is to develop the series of wiper with new technology, extend the market through reducing the cost of the development cost and develop new wiper rubber. Strategy of purchase is to build a system of strategic purchase (reducing the prime cost: 20% , reducing the material cost: 8%), re

(Finding 'a' with using shrinkage equation)
3. Finding 'a'=66.39
■ Result discussion
Because we used a broken gage, we're choosing remains of 2 gages.
The greatest error in shrinkage test was that we couldn't get a expected strain; because we had a mistake not exactly attaching gages.
2.8 Creep
error since compressive strength did not reach proportion strength. It is secondary result as it can't reach compression strength
- Considering Poisson's ratio is in 0.16~0.22, cylinder 1 and 2 was in range of theoritical value. This shows there was proper uniformity in between well attached strain gauge and cylinder.
- Shear strength compressive strength of cylinder 1 and compressive strength
machine firsthand. Therefore, they save cost to development of skills.
If DJC go into America with this way, it will be big threat to ACC.
2. How big are the cost differences between DJC’s plant and American Connector’s Sunnyvale plant? Consider both DJC’s performance in Kawasaki and its potential in the United States.

ability to manufacture many identical goods at once - ex) breakfast cereals, soft drinks
Intermittent process
A production process that uses short production runs to make batches of different products
ex) machines are shut down to make diff. products
