</B><>< mso-char-indent-size: mso-char-indent-count: 11.95pt? 1.31; 15.7pt;>本题第一问须得出观众在出行、用餐和购物等方面的规律,我们理解为通过此规律跟实际情况的对比来考虑提供的数据的可信度。其他需要统计的规律均要以问题2的数据需要来考虑。因此先进行数据可信度的分析。然后进行问题2的分析,在这基础上再进一步统计数据的规律。 <P><P><P mso-char-indent-size: mso-char-indent-count: 11.95pt? 1.31; 15.7pt;>1.使用access对数据的查询得:表1中1~4的年龄段的个数分别为382,2029,711,378。表2中为377,1821,653,349。表3中为415,2300,775,410。由以上的数据很容易看出,20~30岁年龄段人数明显多于其他年龄段人数,30~40年龄段次之,10~20、40~50岁年龄段人数最少。由于调查是随机的,这样的数据符合实际情况,即观看比赛的年轻人(在20~30年龄段内)较多。因此我们可以把3个表的调查数据看成是可信的。 <P><P><P><P><P><P mso-char-indent-size: mso-char-indent-count: 11.95pt? 1.31; 15.7pt;>2.第2问须求出20个商圈人流量的分布,由假设(1)得:所有人都坐车选择最短路进场馆观看比赛时20个商圈有人流量,比赛结束后选择最短路径去餐馆进餐时也有人流量。 <P><P><P mso-char-indent-size: mso-char-indent-count: 11.95pt? 1.31; 15.7pt;>可分入场与出场两部分求每个商圈的人流量。 <P><P><P mso-char-indent-size: mso-char-indent-count: 11.95pt? 1.31; 15.7pt;>入场时,由于附录的数据可信,由所给调查数据得出出行方式分别为公交(南北)、公交(东西)、出租、私车、地铁(东)、地铁(西)的人数百分比,此百分比即可用来表示在入场时,使用6种不同交通工具的人数百分比。如表(1),由所给3次问卷调查的数据得出使用各交通工具的总人数的平均值: <P mso-char-indent-size: mso-char-indent-count: 11.95pt? 1.31; 15.7pt;>由此得出使用6种交通工具的人数百分比为:公交(南北)<V:SHAPE> <V:IMAGEDATA></V:IMAGEDATA></V:SHAPE>=16.7665%,公交(东西)<V:SHAPE> <V:IMAGEDATA></V:IMAGEDATA></V:SHAPE>=17.2513%,出租<V:SHAPE> <V:IMAGEDATA></V:IMAGEDATA></V:SHAPE>=18.9562%,私车<V:SHAPE> <V:IMAGEDATA></V:IMAGEDATA></V:SHAPE>=9.0386%,地铁(东)<V:SHAPE> <V:IMAGEDATA></V:IMAGEDATA></V:SHAPE>=18.9065%,地铁(西)<V:SHAPE> <V:IMAGEDATA></V:IMAGEDATA></V:SHAPE>=19.0809%。 <P><P><P mso-char-indent-size: mso-char-indent-count: 11.95pt? 1.31; 15.7pt;>从题目中图(2),由假设(4),按照最短路径目测出出行方式分别为公交(南北)、公交(东西)、出租、私车、地铁(东)、地铁(西)对3个场馆的进出口选择,由于图2为实物的缩略图,并且在目测过程中对路径的选择并不存在难以判断的现象。得出出行方案如下表所述: <P><P><P mso-char-indent-size: mso-char-indent-count: 11.95pt? 1.31; 15.7pt;>表(2) <P><P><DIV align=center><TABLE border=1 cellPadding=0 cellSpacing=0 style="BORDER-BOTTOM: medium none; BORDER-COLLAPSE: collapse; BORDER-LEFT: medium none; BORDER-RIGHT: medium none; BORDER-TOP: medium none; mso-border-alt: solid windowtext .5pt; mso-padding-alt: 0cm 5.4pt 0cm 5.4pt"><TR 22.4pt?><TD vAlign=top width=91 windowtext? solid .5pt mso-diagonal-down: WIDTH: 0cm; PADDING-TOP: 5.4pt; PADDING-RIGHT: PADDING-LEFT: PADDING-BOTTOM: 22.4pt; HEIGHT: solid; 0.5pt windowtext BORDER-TOP: BORDER-RIGHT: BORDER-LEFT: 68.4pt;><P 25.5pt?>出行 <P><P><P>场馆 <P>

兄弟消消气 现实就是这样的 我的算法 他们听不懂 就算是我白做 郁闷 老师也说越简单越好 (都不想想时间复杂度 汗...我是做B题的) 所以没事哈 加油把 美国竞赛换组

<>呵呵 我们的模型和楼上的很象,也是进行阶段划分,在交通偏好 饮食偏好 以及最短路径原则下 可以测算出各个场馆入口的人流量。第二步的话,没有这么简单的,大家可以想一下,观众在同一个场馆的不同商区是在不停的进行转移的,因此采用一些比例算法是不符实际的,只是流于形式。这时候,借鉴流体动力学思想,把过程看成人流在入场口向场内发散,建立微分方程组,通过调整里面的时间因素T,可以模拟实际中的人流情况,最后达到一个稳定状态即为该阶段的各商区的人流量。</P>
