干货！2014年美赛O奖论文

号外号外 2016年美国大学生数学建模竞赛将于美国东部时间2016年1月28日20点至2月1日20点 即北京时间2016年1月29日9点至2月2日9点举行 不过稍微关心下美赛的童鞋都应该知道比赛时间吧

国赛取得好成绩的童鞋不要太骄傲了 毕竟我看过不少拿了国奖却没拿到美一的童鞋  至于在国赛发挥不佳的童鞋也不要妄自菲薄 因为我也看到不少美赛中的黑马

对于有意参加明年美赛但又没参加过的童鞋 总有不少问题要问的 比如‘美赛相比国赛而言更难吗’ ......

找了几篇2014年美赛A题和B题的O奖论文 大家可以下载来感受感受 （没发2015年是因为暂时没找到国内O奖论文 下次找到了再分享给大家）

下面附上2014年美赛A、B题题目 别问我为什么不上中文版 如果连英文版题目都看不下去的话更别说是英文版论文了

PROBLEM A: The Keep-Right-Except-To-Pass Rule
In countries where driving automobiles on the right is the rule (that is, USA, China and most other countries except for Great Britain, Australia, and some former British colonies), multi-lane freeways often employ a rule that requires drivers to drive in the right-most lane unless they are passing another vehicle, in which case they move one lane to the left, pass, and return to their former travel lane.
Build and analyze a mathematical model to analyze the performance of this rule in light and heavy traffic. You may wish to examine tradeoffs between traffic flow and safety, the role of under- or over-posted speed limits (that is, speed limits that are too low or too high), and/or other factors that may not be explicitly called out in this problem statement. Is this rule effective in promoting better traffic flow? If not, suggest and analyze alternatives (to include possibly no rule of this kind at all) that might promote greater traffic flow, safety, and/or other factors that you deem important.
In countries where driving automobiles on the left is the norm, argue whether or not your solution can be carried over with a simple change of orientation, or would additional requirements be needed.
Lastly, the rule as stated above relies upon human judgment for compliance. If vehicle transportation on the same roadway was fully under the control of an intelligent system – either part of the road network or imbedded in the design of all vehicles using the roadway – to what extent would this change the results of your earlier analysis?

PROBLEM B: College Coaching Legends
Sports Illustrated, a magazine for sports enthusiasts, is looking for the “best all time college coach” male or female for the previous century. Build a mathematical model to choose the best college coach or coaches (past or present) from among either male or female coaches in such sports as college hockey or field hockey, football, baseball or softball, basketball, or soccer. Does it make a difference which time line horizon that you use in your analysis, i.e., does coaching in 1913 differ from coaching in 2013? Clearly articulate your metrics for assessment. Discuss how your model can be applied in general across both genders and all possible sports. Present your model’s top 5 coaches in each of 3 different sports.
In addition to the MCM format and requirements, prepare a 1-2 page article for Sports Illustrated that explains your results and includes a non-technical explanation of your mathematical model that sports fans will understand.
