ProblemB: City Crime and Safety

What can we makeof the massive amount of crime statistics collected in major cities? Beyondjust reporting numbers, how can we use these data to determine the safeness ofa city?

Assume that youand your modeling team live in My City, a large international hub of commerce,technology, finance and travel, with a current population of 2.8 million peopleimpacted by a metropolitan area of an additional approximately 6 millionpeople.

The data setprovided (My_City_Crime_Data.xlsx   ) shows two weeksfrom police reports in My City and includes crimes listed by case number, dateof occurrence, primary and secondary crime descriptions, crime location,whether an arrest was made, whether or not this was domestic crime, and thebeat number of the police route.  

Part I:Using mathematical modeling, analyze the data. Create a safetyrating for My City. Use your safety rating to specify a measure of how safe MyCity is.

Part II: In addition to the HiMCM contest format, prepare a 1-2 pagenon-technical report for the Mayor of My City to describe your findings.

在大城市里,我们可以利用大量的犯罪统计数据做什么呢?除了报告数字,我们如何利用这些数据来确定城市的安全性?假设你和你的建模团队住在我的城市,一个大型的国际商业、技术、金融和旅游中心,目前拥有人口2、8亿,并受到一个额外有人口约6亿的大都市影响。数据集提供(my_city_crime_data.xlsx)显示在我市两周内警方的报告,包括案件编号,事发日期,原发性和继发性犯罪的描述,犯罪地点,是否逮捕了,是否是国内犯罪,与警察巡逻路线(the beat number of the police route原英文)。第一部分:运用数学建模,对数据进行分析。为我的城市创造一个安全等级。使用你的安全等级来衡量我的城市是多么安全。第二部分:除了对himcm竞赛形式,准备为我市市长描述你的发现的1-2页的技术报告。
