align=center>A题：失业工人如何选择满意工作
<

>政府为解决失业工人的再就业问题，积极提供就业机会，同时每月为每一位失业工人发放一定数量的失业救济金，作为他们基本的生活保障。失业工人在寻找工作的时候，若接受找到的第一个工作，则意味他放弃了继续寻找可能找到更好工作的机会。因此，失业工人一般不会马上接受找到的第一个工作，他通常会在心里预先设定一个最低工资水平，若找到的工作其工资低于这个预先设定的最低工资水平，则放弃该工作，继续寻找下一个工作，直至找到高于或等于预先设定的最低工资水平的工作为止。 请你建立适当的数学模型，给出最低工资水平的决定条件，失业救济金和最低工资水平的关系，并对失业工人找到满意工作之前的平均等待时间（单位：月）做出合理的估计

21pt; LINE-HEIGHT: 17pt; mso-line-height-rule: exactly; mso-char-indent-count: 2.0; mso-char-indent-size: 10.5pt">某保险公司只提供一年期的综合车险保单业务，这一年内，若客户没有要求赔偿，则给予额外补助，所有参保人被迫分为0，1，2，3四类，类别越高，从保险费中得到的折扣越多。在计算保险费时，新客户属于0类。在客户延续其保险单时，若在上一年没有要求赔偿，则可提高一个类别；若客户在上一年要求过赔偿，如果可能则降低两个类别，否则为0类。客户退出保险，则不论是自然的还是事故死亡引起的，将退还其保险金的适当部分。<

21pt; LINE-HEIGHT: 17pt; mso-line-height-rule: exactly; mso-char-indent-count: 2.0; mso-char-indent-size: 10.5pt">现在政府准备在下一年开始实施安全带法规，如果实施了该法规，虽然每年的事故数量不会减少，但事故中受伤司机和乘员数肯定会减少，从而医药费将有所下降，这是政府预计会出现的结果，从而期望减少保险费的数额。这样的结果真会出现吗？这是该保险公司目前最关心的问题。根据采用这种法规的国家的统计资料可以知道，死亡的司机会减少40%，遗憾的是医疗费的下降不容易确定下来，有人认为，医疗费会减少20%到40%，假设当前年度该保险公司的统计报表如下表1和表2。保险公司希望你能给出一个模型，来解决上述问题，并以表1和2的数据为例，验证你的方法，并给出在医疗费下降20%和40%的情况下，公司今后5年每年每份保险费应收多少才比较合理？给出你的建议。

<

>这些是刚刚结束的江苏省的一次数学建模比赛的题目。<

>想怎么做就怎么做呗建模又没有标准答案的 <

>大家可以去矿业大学的网站去查询一下，应该有优秀获奖论文之类，我查到了一定把网址告诉大家，谁要查到了，请也公布一下，谢谢。
