2004年全国大学生数学建模竞赛将于2004年9月份举行,为了加强我校数学建模竞赛的成绩和影响,决定从全校范围内选拔今年的参赛队员,现就有关我校参加2004年全国数学建模竞赛的一些安排通知如下:
一. 参赛队数:
2004年我校将组织约10个参赛队。
二. 选拔办法:
通过3次选拔赛的方式来决定最后的10支参赛队伍。三次模拟数学建模竞赛的平均成绩作为最后参加集训的主要参考。
三. 参赛队员:
凡我校正式注册的本科生均可以报名参加。
四. 时间安排:
第一次模拟(选拔)考试时间为2004年4月2日~4月10日。模拟试题为今年的美国数学建模竞赛的试题,见附件1。
其余两次模拟时间待定!
五. 模拟论文格式:
用A4纸打印,论文的第一页为你所做论文的题目、班级、学号以及姓名;第二页为空白页,从第三页开始写论文。
六. 模拟论文的评分标准:
建立的数学建模中假设的合理性、建模的创造性、结果的正确性、表达的清晰性。
七. 参赛形式:
由三位同学组成一队,在做论文期间可以参考除人以外的所有的资料与资源。

A 题: 指纹是独一无二的吗?
人们普遍相信每个人的指纹都是不同的。请研制并分析能评估这种说法是正确的可能性的模型,然后把你们在这个问题中发现的指纹识别错误率与DNA识别错误率相比较。
PROBLEM A: Are Fingerprints Unique?
It is a commonplace belief that the thumbprint of every human who has ever lived is different. Develop and analyze a model that will allow you to assess the probability that this is true. Compare the odds (that you found in this problem) of misidentification by fingerprint evidence against the odds of misidentification by DNA evidence.
B 题: 更快的快通系统
无论是在收费站、游乐场或其他地方正出现着越来越多的"快通"系统以减少人们排队等候的时间。请考虑一家游乐场的快通系统的设计。这家游乐场已经为几种受欢迎的乘骑项目提供快通系统的服务作为试验。该系统的设计思想是对某些受欢迎的乘骑项目,游客可以到该娱乐项目旁边的一个机器前并将当天的门票插入, 该机器将返回给你一张纸条,上面写着你可以在某个特定的时间段回来。比如说你把你的门票在1:15pm插到机器里,快通系统就告诉你可以在3:30-4:30pm回来,你可以凭你的纸条第二次排队,这时队伍可能比较短,你就可以较快进入景点. 为了防止游客同时在几个乘骑娱乐项目上使用这个系统。一个顾客在同一时刻只能得到一次快通系统的服务。
为改进快通系统的运作你们队被聘为几个合格的顾问之一. 游客一直在抱怨该试验系统的一些异常现象. 比如说, 顾客有时看到快通系统提供的回到景点时间是4小时以后. 但是才过一小会,在相同的景点系统所提供的回到景点的时间只有1小时或稍多一点时间。有时按照快通系统安排的游客的人数和等待时间几乎和正常排队的人数和所花费的时间一样多。
于是问题就是要提出并检验能提高快通系统效率的方案以使人们可以更多地享受在游乐场的休闲时光。问题的一部分是要确定评估各种可供选择的方案的评价准则。你们的报告中要包括一份非技术性的概述,以便游乐场主管从各个顾问所提出的可供选择的方案中作出选择。
PROBLEM B: A Faster QuickPass System
"QuickPass" systems are increasingly appearing to reduce people's time waiting in line, whether it is at tollbooths, amusement parks, or elsewhere. Consider the design of a QuickPass system for an amusement park. The amusement park has experimented by offering QuickPasses for several popular rides as a test. The idea is that for certain popular rides you can go to a kiosk near that ride and insert your daily park entrance ticket, and out will come a slip that states that you can return to that ride at a specific time later. For example, you insert your daily park entrance ticket at 1:15 pm, and the QuickPass states that you can come back between 3:30 and 4:30 pm when you can use your slip to enter a second, and presumably much shorter, line that will get you to the ride faster. To prevent people from obtaining QuickPasses for several rides at once, the QuickPass machines allow you to have only one active QuickPass at a time.
You have been hired as one of several competing consultants to improve the operation of QuickPass. Customers have been complaining about some anomalies in the test system. For example, customers observed that in one instance QuickPasses were being offered for a return time as long as 4 hours later. A short time later on the same ride, the QuickPasses were given for times only an hour or so later. In some instances, the lines for people with Quickpasses are nearly as long and slow as the regular lines.
The problem then is to propose and test schemes for issuing QuickPasses in order to increase people's enjoyment of the amusement park. Part of the problem is to determine what criteria to use in evaluating alternative schemes. Include in your report a non-technical summary for amusement park executives who must choose between alternatives from competing consultants.
