1.    生产glass和glass object的生产model有centralized和disperse两种
2.    有两种strategy:transactional和transformational.第一段介绍两种strategy,第二段讲不同personality的人喜欢用哪种strategy以及推测为什么
3.    很长,有三四小段。有一个“efficiency assortment(还是assortment efficiency)”。然后商家担心这个策略会带来不好的影响,但其实risk is small

数学
1. 最后一题:有一个committee需要三男三女,要从7男7女里选,问有几种情况,答案有(7!)^2, 35^2等
2. 有一个点(x, 0)到(1,-3)和(8,4)的距离一样,求x?是(1,-3)
3. 相似三角形问题:一个人从A点开始往远离旗杆O的w方向以2/s的速度走,问影子的增长速度是多少

请问lz第三篇是这篇文章吗?
If a product has a finite 【有限的】 selling season and uncertain demand, retail overstock is a possibility. Anticipating how such surplus will devalue, the retailer may stock less of the item than the manufacturer would like, if any at all. As illustrated by P&G, manufacturer return policies and markdown money are two common strategies used by manufacturers to combat this tendency. Both work by decreasing the retailer's net cost of overstock.


如果某种产品销售季有限且需求不确定,零售商就有可能存货过多。通过对这些过剩产品贬值的预期,零售商可能至少会存较制造商期望的少的存货。P&G案例表明,return和markdown补贴策略是制造商弥补这一趋势的两种常用策略。两种策略都旨在降低过剩存货的净成本。


Return policies are often observed when demand is unpredictable and/or the risk of obsolescence(过时) is high, as extensively documented by Padmanabhan and Png (1995) and Kandel (1996). Markdown money also has a rich tradition among products facing such environments, including fashion apparel(时装) (Ryan 1998; Monget 1998), cosmetics and fragrances (Parks 1996), toys (Leccese 1993), specialty products (Gallagher 1999), certain food categories and over-the-counter medications (Tenser 1997). However, nothing in our discussion thus far suggests if, when, or why either method might be preferable to the other.


Return 策略通常用在当需求难以预测,并且/或者产品过时的风险很高时。……Markdown money策略常用在时装、化妆品香氛、玩具、专用产品、某些特定食品和OTC药物中。……


The academic literature is silent on these questions. Return policies are certainly relatively well-studied (Pasternack 1985; Kandel 1996; Padmanabhan and Png 1997; Emmons and Gilbert 1998; Donohue 2000; Webster and Weng 2000), as will be discussed in greater detail in the next section. These works advocate return policies as a way to improve the efficiency of the channel to the participants' mutual benefit(共同利益). However, this conclusion relies on two assumptions that mask the differences between the practices in question:


(1) the physical return of product does not incur additional cost, and


(2) the channel members are equally effective at liquidating(清偿) overstock (2).


The first assumption is problematic in that the handling, logistics, and administrative overhead(费用) associated with moving product back up the channel may be substantial(实际存在的). For instance, P&G Cosmetics has calculated that each handling of an item (because of damage, discontinuation, or simple return) costs 34 cents, a nontrivial(重大的) fraction of typical profit margins for such products (Born 1997). And Hal Upbin, CEO of Kellwood Co. (a manufacturer of ready-to-wear apparel(非定制成衣)) notes, "We don't take anything back; the cost of handling would be absurd (Infotracs 1997)."


……这些研究支持return policy来提高渠道效率实现双方的共同利益。然而,这个结论是基于对现实中实际不同的以下两个假设而作出的:


(1)产品的实体返回不会产生附加成本


(2)各渠道成员在清偿存货方面同等有效


第一个假设是有问题的,因为把存货运回渠道上游(制造商)处理、运输、管理的费用确实是实际存在的。例如,P&G日化曾计算过(由于损坏、废弃、或者简单的发回)每件产品的处理费用是34美分,相当于该产品通常利润的很大部分。成衣制造商的CEO H·U也说:“我们不回收任何产品,处理成本太不合理了”


With respect to the second assumption, the reality is that recovering value from surplus product is a substantive professional competency(能力), and different parties likely have different aptitude and tolerance for this (Hungerford 1999). The retailer obviously has the most immediate option, i.e., to sell to the same customer base at a discount. Indeed, access to markets and comparative advantage in merchandising(广告推销) are among the underlying reasons a retail channel would be used in the first place, and these factors should persist at the clearance phase(清仓甩卖阶段). However, if the residual(剩余的) value comes from recovering and reusing the raw materials, the manufacturer could have an advantage. Also, by consolidating(合并) the returns from multiple retailers a manufacturer might be able to assemble an assortment that becomes economically viable for resale to a discount specialist (e.g., T. J. Maxx in the apparel industry). Additional aging of the product and potential damage during the processing of returns should be considered, of course. Similar points are raised, but not formally pursued, by Kandel (1996) and Padmanabhan and Png (1997).


针对第二项假设,现实情况是从过剩产品中找回价值是一个相当具有专业要求(的过程),并且各方对此的倾向和耐受力也不同。零售商们显然有最直接的方法,即以折扣方式卖给同样的消费群。实际上,接近市场和广告优势是削弱零售作为首要渠道的的原因之一,而且这些因素在清仓甩卖阶段仍然存在。然而,如果可以回收多个零售商的原材料对剩余价值加以利用,制造商就能获得竞争优势。同样,将多个零售商的return合并在一起组成在经济上可以再销售的专用折扣组合。当然,产品的额外老化和产品返回过程中的潜在折损应该被考虑进去。……

谢谢!!!

谢谢楼主!!求问影子这题怎么做??

增长速度=增长的长度/时间,假设时间为t,之后的影子=2t+5(等腰三角形,等与三角形的底边),所以增长的就是2t,所以增长速度=2.
如有错误请指正

不是5/2=2.5S (25-5)/2.5=8/s 吗?
