请问：陕西省的成绩在哪里可以找到，还是根本就没出来？

帮个忙啊  这个题型好难啊有谁能做哈啊  题目:试用层次分析法解决如下问题：学校评选优秀学生，试给出若干准则，构造层次结构模型。（注，可分为相对评价和绝对评价两种情况讨论）

那位高手帮个忙哦,小弟实在是没得办法了,明天就要交论文了啊,这道数模题为:某生产厂家年初要制定生产策略，已预知其产品在年初的需求量为a=6万单位，并以b=1万单位/季度速度递增。若生产产品过剩，则需付单位产品单位时间（季度）的库存保管费<span style="

好啊,顶,顶,我也要参加

偶是新手~不能发话题~~不知道这论坛怎么设置的希望大家帮忙做下 某厂用一套设备生产若干种产品。工厂靠银行贷款筹集资金，根据市场需求安排生产，现考虑以下的简化情形<div style="mso-margin-left-alt: 216; mso-char-wrap: 1; mso-kinsoku-overflow: 1;"> 
<div class="O" vshape="_x0000_s1026" style="mso-char-wrap: 1; mso-kinsoku-overflow: 1;">设生产甲乙两种产品,
市场对它们的需求分别为d1,d2 (件/天)，该设备生产它们的最大能力分别为U1,U2 (件/天)，生产成本分别为c1,c2 (元/件)。当改变产品时因更换零部件等引起的生产甲乙前的准备费用分别为
s1,s2(元)。生产出的产品因超过当天的需求而导致的贮存费用，按生产成本的月利率r引起的积压资金的k倍计算（每月按30天计）。</div><div class="O" vshape="_x0000_s1026" style="mso-char-wrap: 1; mso-kinsoku-overflow: 1;">  <div class="O" vshape="_x0000_s1026" style="mso-char-wrap: 1; mso-kinsoku-overflow: 1;">设每种产品的生产率都可以从零到最大能力之间连续调节，每种产品当前的需求均需满足。请您为工厂制订合理、易行的生产计划，使上面考虑到的费用之和尽可能小。</div></div></div>
