PROBLEM B: How Many Languages?

Background: There are currently about 6,900 languages spoken on Earth. About half the world’s

population claim one of the following ten languages (in order of most speakers) as a native language:

Mandarin (incl. Standard Chinese), Spanish, English, Hindi, Arabic, Bengali, Portuguese, Russian,

Punjabi, and Japanese. However, much of the world’s population also speaks a second language. When

considering total numbers of speakers of a particular language (native speakers plus second or third, etc.

language speakers), the languages and their order change from the native language list provided. The

total number of speakers of a language may increase or decrease over time because of a variety of

influences to include, but not limited to, the language(s) used and/or promoted by the government in a

country, the language(s) used in schools, social pressures, migration and assimilation of cultural groups,

and immigration and emigration with countries that speak other languages. Moreover, in our globalized,

interconnected world there are additional factors that allow languages that are geographically distant to

interact. These factors include international business relations, increased global tourism, the use of

electronic communication and social media, and the use of technology to assist in quick and easy

language translation.

Problem: A large multinational service company, with offices in New York City in the United States

and Shanghai in China, is continuing to expand to become truly international. This company is

investigating opening additional international offices and desires to have the employees of each office

speak both in English and one or more additional languages. The Chief Operating Officer of the

company has hired your team to investigate trends of global languages and location options for new

offices.

Part I:

A. Consider the influences and factors described in the background paragraph above, as well as other

factors your group may identify. Based on projected trends, and some or all of these influences and

factors, model the distribution of various language speakers over time.

B. Use your model to predict what will happen to the numbers of native speakers and total language

speakers in the next 50 years. Do you predict that any of the languages in the current top-ten lists

(either native speakers or total speakers) will be replaced by another language? Explain.

C. Given the global population and human migration patterns predicted for the next 50 years, do the

geographic distributions of these languages change over this same period of time? If so, describe the

change.

Part II:

A. Based on your modeling from Part I, and assuming your client company wants to open six new

international offices, where might you locate these offices and what languages would be spoken in

the offices? Would your recommendations be different in the short term versus the long term?

Explain your choices.

B. Considering the changing nature of global communications, and in an effort to save your client

company resources, might you suggest that the company open less than six international offices?

Indicate what additional information you would need and describe how you would analyze this

option in order to advise your client.

Part III:

Write a 1-2 page memo to the Chief Operating Officer of the service company summarizing your

results and recommendations.

Note: In your analysis, ignore unpredictable or high-impact, low probability events such as asteroid

collisions that would cause a catastrophic jump in evolutionary trends over time, and possibly render all

languages extinct.

Your submission should consist of:

􀁸 One-page Summary Sheet,

􀁸 Two-page memo,

􀁸 Your solution of no more than 20 pages, for a maximum of 23 pages with your summary and

memo.

􀁸 Note: Reference list and any appendices do not count toward the 23-page limit and should appear

after your completed solution.


B题中文翻译:

问题B:多少种语言?

背景:目前地球上大约有6900种语言。世界的一半人口声称有下列十种语言之一(以大多数人的语言)为母语:

普通话(标准中文),西班牙语,英语,北印度语,阿拉伯语,孟加拉语,葡萄牙语,俄语,旁遮普语和日语。然而,世界上大部分人口也会说第二种语言。当考虑一种特定语言的总人数(以英语为母语的人加第二或第三名,等等)。语言使用者),语言和他们的顺序从提供的本地语言列表。的随着时间的推移,语言使用者的总数可能会随着时间的变化而增加或减少。影响包括但不限于政府在a中使用和/或推动的语言。国家、学校使用的语言、社会压力、文化群体的迁移和同化,移民和移民与说其他语言的国家。此外,在我们的全球化,相互联系的世界里还有一些其他的因素,使得在地理上遥远的语言。交互。这些因素包括国际商务关系、全球旅游的增加、使用。电子通讯和社交媒体,以及利用技术来帮助快速和容易。

问题:一家大型跨国服务公司,在美国纽约设有办事处。而上海在中国,正继续扩展成为真正的国际化。本公司是调查开设额外的国际办事处,并要求每个办事处的雇员。用英语和一种或多种语言说。首席运营官。公司已经聘请您的团队调查全球语言的趋势和新的位置选项。

办公室

A.考虑上述背景段所描述的影响和因素,以及其他因素。你的团队可能认同的因素。根据预测的趋势,以及一些或所有这些影响。因素,模型随着时间的推移,各种语言使用者的分布。

用你的模型来预测母语使用者和总语言的数量。在接下来的50年里。你能预测出目前排名前十的语言吗?(以英语为母语的人或总讲者)会被另一种语言取代吗?解释一下。


第二部分:

基于你在第一部分的建模,假设你的客户公司想要打开6个新的。国际办公室,你可以在哪里找到这些办公室和什么语言。办公室吗?你的建议在短期和长期内会有所不同吗?

解释你的选择。

B.考虑到全球通信的变化性质,并努力拯救你的客户。

公司资源,你是否建议公司在6个以上的国际办事处开业?

说明你需要哪些额外信息,并描述如何分析这些信息。

选择,以通知你的客户。

第三部分:

写一份1-2页的备忘录给服务公司的首席运营官总结你的工作。

结果和建议。

注:在你的分析中,忽略不可预测或高冲击,低概率事件,如小行星。随着时间的推移,碰撞将导致进化趋势的灾难性的跳跃,并可能导致所有的结果。

语言灭绝。

你的提交应包括:

•页表,

•两页的备忘录,

•您的解决方案不超过20页,最多23页和总结

备忘录。

•注意:参考列表和任何附件不能算在一份长达23页的限制,应该出现

在你完成的解决方案。


您的MCM提交应包括三个要素:标准的1页MCM摘要表,1-2页简要评估报告(要求1)和您的主要MCM解决方案(要求2)不超过20页,最多提交23页面。注意:您加入的任何附录或参考页面不会计入23页的上限。
