[求助]一道寂静AA题的解题思路

1.       官方题库21页第三题

“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.” 3次

这道题目有哪三个地方存在逻辑错误呀？请大家给点意见~

1. 其他的工厂未必能生产其他的零件或者和这个工厂有同样的效率
2. 这个零件的产值可能只占这个公司生产总值的一小部分，这样这个零件成本的减少不能带来整个公司成本的降低
3. 由此带来的成本降低不能抵消由于机械转移等其他费用
这是我对这篇AA的观点，不过一战碰到只得了4.5，当时就是这篇，所以仅供参考

我认为有３个错误（请大家指正）

１、        别的工厂转用factory in Cookville的生产线来节省成本方法不一定可行。因为我们无法知道other factories的生产线是否与factory in Cookville的生产线是同样的。也就是说，factory in Cookville的drill bits有可能与other factories的drill bits有可能型号不一样，要求不一样。如果简单地凭每小时的生产量就认为factory in Cookville的效率更高是不对的。有可能因为转用factory in Cookville的生产线，使得产品不合格，反而提高了成本。

２、        说到降低生产成本的唯一方法就是reducing the production costs of individual machine parts，太绝对了。降低overall production costs的方法有很多种。比如说，降低人力成本，仓储物料成本也可以。

３、        概念模糊。larger goal的具体是什么，我们不清楚。仅仅降低了生产水平，并不一定就可以达到larger goal。

切尔西的“由此带来的成本降低不能抵消由于机械转移等其他费用”

很有启发。。。
