运筹学基础课后习题答案

运筹学基础课后习题答案 [2002年版新教材] 第一章导论 P5 1.、区别决策中的定性分析和定量分析,试举例。 定性——经验或单凭个人的判断就可解决时,定性方法 定量——对需要解决的问题没有经验时;或者是如此重要而复杂,以致需要全面分析(如果涉及到大量的金钱或复杂的变量组)时,或者发生的问题可能是重复的和简单的,用计量过程可以节约企业的领导时间时,对这类情况就要使用这种方法。 举例:免了吧。。。 2、. 构成运筹学的科学方法论的六个步骤是哪些? .观察待决策问题所处的环境; .分析和定义待决策的问题; .拟定模型; .选择输入资料; .提出解并验证它的合理性(注意敏感度试验); .实施最优解; 3、.运筹学定义: 利用计划方法和有关许多学科的要求,把复杂功能关系表示成数学模型,其目的是通过定量分析为决策和揭露新问题提供数量根据 第二章作业预测P25 1、. 为了对商品的价格作出较正确的预测,为什么必须做到定量与定性预测的结合?即使在定量预测法诸如加权移动平均数法、指数平滑预测法中,关于权数以及平滑系数的确定,是否也带有定性的成分? 答:(1)定量预测常常为决策提供了坚实的基础,使决策者能够做到心中有数。但单靠定量预测有时会导致偏差,因为市场千变万化,影响价格的因素很多,有些因素难以预料。调查研究也会有相对局限性,原始数据不一定充分,所用的模型也往往过于简化,所以还需要定性预测,在缺少数据或社会经济环境发生剧烈变化时,就只能用定性预测了。(2)加权移动平均数法中权数的确定有定性的成分;指数平滑预测中的平滑系数的确定有定性的成分。 2.、某地区积累了5 个年度的大米销售量的实际值(见下表),试用指数平滑法,取平滑系数α= 0.9,预测第6年度的大米销售量(第一个年度的预测值,根据专家估计为4181.9千公斤) 年度 1 2 3 4 5 大米销售量实际值 (千公斤)5202 5079 3937 4453 3979 。 答: F6=a*x5+a(1-a)*x4+a(1-a)~2*x3+a(1-a)~3*x2+a(1-a)~4*F1 F6=0.9*3979+0.9*0.1*4453+0.9*0.01*3937+0.9*0.001*5079+0.9*0.0001*4181.9

Employees go there during breaks, lunch, and dinner. The maintenance department supplies containers for garbage and ashtrays for cigaret te butts. But when they finish their food the employees will either throw their papers on the floor or leave them on the table. Some employees will on occasion throw their papers in the garbage container, but most of them who smoke will eithe r flick their ashes on the floor or in the half-filled soda cups. Cigarette butts are found anywhere other than in the ashtray, because the ashtrays may have been stolen or have been filled with gum. Sometimes an employee will remark, “ Aren ’ t these people pigs? They don ’ t even up after themselves,” as they proceed to walk away fromtheir littered table.
