發(fā)布日期:2004-04-05 閱讀次數(shù):
2004年全國大學生數(shù)學建模競賽將于2004年9月份舉行,,為了加強我校數(shù)學建模競賽的成績和影響,,決定從全校范圍內選拔今年的參賽隊員,現(xiàn)就有關我校參加2004年全國數(shù)學建模競賽的一些安排通知如下:
一. 參賽隊數(shù):
2004年我校將組織約10個參賽隊,。
二. 選拔辦法:
通過3次選拔賽的方式來決定最后的10支參賽隊伍,。三次模擬數(shù)學建模競賽的平均成績作為最后參加集訓的主要參考。
三. 參賽隊員:
凡我校正式注冊的本科生均可以報名參加。
四. 時間安排:
第一次模擬(選拔)考試時間為2004年4月2日~4月10日。模擬試題為今年的美國數(shù)學建模競賽的試題,,見附件1。
其余兩次模擬時間待定,!
五. 模擬論文格式:
用A4紙打印,,論文的第一頁為你所做論文的題目、班級,、學號以及姓名,;第二頁為空白頁,,從第三頁開始寫論文,。
六. 模擬論文的評分標準:
建立的數(shù)學建模中假設的合理性、建模的創(chuàng)造性,、結果的正確性,、表達的清晰性。
七. 參賽形式:
由三位同學組成一隊,,在做論文期間可以參考除人以外的所有的資料與資源,。

A 題: 指紋是獨一無二的嗎?
人們普遍相信每個人的指紋都是不同的,。請研制并分析能評估這種說法是正確的可能性的模型,,然后把你們在這個問題中發(fā)現(xiàn)的指紋識別錯誤率與DNA識別錯誤率相比較。
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 題: 更快的快通系統(tǒng)
無論是在收費站,、游樂場或其他地方正出現(xiàn)著越來越多的"快通"系統(tǒng)以減少人們排隊等候的時間,。請考慮一家游樂場的快通系統(tǒng)的設計。這家游樂場已經(jīng)為幾種受歡迎的乘騎項目提供快通系統(tǒng)的服務作為試驗,。該系統(tǒng)的設計思想是對某些受歡迎的乘騎項目,,游客可以到該娛樂項目旁邊的一個機器前并將當天的門票插入, 該機器將返回給你一張紙條,上面寫著你可以在某個特定的時間段回來,。比如說你把你的門票在1:15pm插到機器里,,快通系統(tǒng)就告訴你可以在3:30-4:30pm回來,你可以憑你的紙條第二次排隊,,這時隊伍可能比較短,,你就可以較快進入景點. 為了防止游客同時在幾個乘騎娛樂項目上使用這個系統(tǒng)。一個顧客在同一時刻只能得到一次快通系統(tǒng)的服務,。
為改進快通系統(tǒng)的運作你們隊被聘為幾個合格的顧問之一. 游客一直在抱怨該試驗系統(tǒng)的一些異?,F(xiàn)象. 比如說, 顧客有時看到快通系統(tǒng)提供的回到景點時間是4小時以后. 但是才過一小會,,在相同的景點系統(tǒng)所提供的回到景點的時間只有1小時或稍多一點時間。有時按照快通系統(tǒng)安排的游客的人數(shù)和等待時間幾乎和正常排隊的人數(shù)和所花費的時間一樣多,。
于是問題就是要提出并檢驗能提高快通系統(tǒng)效率的方案以使人們可以更多地享受在游樂場的休閑時光,。問題的一部分是要確定評估各種可供選擇的方案的評價準則。你們的報告中要包括一份非技術性的概述,,以便游樂場主管從各個顧問所提出的可供選擇的方案中作出選擇,。
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.
