最近超模君找到了2016美賽A題問題 大家趕緊來圍觀! 2016 MCM Problem A A Hot Bath 熱水浴 A person fills a bathtub with hot water from a single faucet and settles into the bathtub to cleanse and relax. Unfortunately, the bathtub is not a spa-style tub with a secondary heating system and circulating jets, but rather a simple water containment vessel. After a while, the bath gets noticeably cooler, so the person adds a constant trickle of hot water from the faucet to reheat the bathing water. The bathtub is designed in such a way that when the tub reaches its capacity, excess water escapes through an overflow drain. 一個人用熱水從一個水龍頭里灌滿一個浴缸,然后躺在浴缸中,清洗和放松。不幸的是,這個浴缸不是一個具有二次加熱系統(tǒng)和循環(huán)射流的溫泉式浴缸,而是一個簡單的水容器。過了一會兒,洗澡水就會明顯變涼,所以這個人增加了一個可以恒定流出熱水的水龍頭來重新加熱洗澡水。該浴缸的設(shè)計是:當浴缸達到最大容量時,多余的水可以通過溢漏排出去。 Develop a model of the temperature of the bathtub water in space and time to determine the best strategy the person in the bathtub can adopt to keep the temperature even throughout the bathtub and as close as possible to the initial temperature without wasting too much water. Use your model to determine the extent to which your strategy depends upon the shape and volume of the tub, the shape/volume/temperature of the person in the bathtub, and the motions made by the person in the bathtub. If the person used a bubble bath additive while initially filling the bathtub to assist in cleansing, how would this affect your model’s results? In addition to the required one-page summary for your MCM submission, your report must include a one-page non-technical explanation for users of the bathtub that describes your strategy while explaining why it is so difficult to get an evenly maintained temperature throughout the bath water. 在空間和時間上開發(fā)一個浴缸的水的溫度模型,以確定在浴缸的人可以采取的最佳策略以來保持溫度,并用最節(jié)省的水量來使整個浴缸的溫度盡可能接近的初始溫度。 使用你的模型來確定你的策略取決的浴缸的形狀和體積,浴缸的形狀/體積/溫度,浴缸中的人的運動。如果這個人在最初填充浴缸時用了一個泡泡浴劑來協(xié)助洗澡,這會如何影響你的模型的結(jié)果?除了要求的一頁摘要MCM提交,你的報告必須包括一頁給用戶的有關(guān)浴缸的非技術(shù)性的解釋頁,說明你的技術(shù)以及為什么洗澡水的溫度很難達到均勻恒定。 現(xiàn)在 超模君有幸請到2016美賽特等獎獲得者來和大家分享經(jīng)驗 11月18號,超級數(shù)學建模推出美賽培訓計劃之第一節(jié)【美賽特等獎講座】,面向美賽備戰(zhàn)者,而本次課程將深入剖析2016年美賽特等獎?wù)撐模ˋ題)),旨在幫助參賽者深入了解連續(xù)類題目的基本特性,提升相應(yīng)的解題能力,取長補短,吸取比賽經(jīng)驗,讓學習者成為“賽前自信,賽中自如,賽后歡喜”的備戰(zhàn)者。 主講內(nèi)容 分析美賽賽題 講解特等獎?wù)撐哪P秃拖嚓P(guān)程序 分享寫作技巧 總結(jié)參賽經(jīng)驗 時間:11月18日19:30 課時:2小時 更有美賽資深研究專家等來你 關(guān)于課程 永久免費回放 課后老師不定時解答疑問 在超級數(shù)學建模公眾號上,回復四個字: 成功參加【勞動光榮】就能獲得減免 |
