求大牛指点一片augument

“Our factory in Cookville is our most advanced and efficient. It is capable of producing ten drill bits for each dollar of production costs, whereas none of our other factories can produce more than seven drill bits per dollar of production costs. Therefore, we can reduce our overall drill bit production costs by devoting the Cookville factory entirely to drill bit production. Since reducing the production costs of individual machine parts is the only way to achieve our larger goal of reducing our overall production costs, dedicating the Cookville factory entirely to drill bit production and shifting all other machine part production to our other factories will help us to attain that larger goal.”
这篇argument完全没有头绪，哪位高人出来指点一下来？

是不是说投入cookville使其能生产10 drill bits 的成本要大于生产后省下的成本，或是说如果c能生产10是在不满负荷的情况下，而满负荷运行成本会很高，也就是说总成本在方案转换以后反而增加了。另外就是由于c 工厂太远，shifting 的成本也比省下的多。个人觉得三个点都可以切入。

the problems of this argu is :
1 the factory in cookville is the most advanced and efficient in what? we don't know it. it might be the drill bits, or not.
2 do other factories only produce drill bits? we don't know. maybe other factories produce other things that more profitable. and that may be why factory in cookville produce drill bits, maybe because the cookville factory can not produce other more profitable things
3 what if cookville can not produce enough drill bits, that is why they need other factories to produce drill bits? although other factories may not be so efficient in producing drill bits.
4 drill bits means machine parts or just a part of machine parts? maybe individual machine parts include drill bits and other machine parts, so to reduce the overall production costs they also need to reduce to production costs of other machine parts.
