二、名词解释(3分*5=15分):Xjs★济宁成人高考报名电话0537-2229526

1、现金流入:相对某个系统,在某一时点上流入系统的资金或货币量,如销售收入等。Xjs★济宁成人高考报名电话0537-2229526

2、折现(贴现):把将来某一时点的资金金额换算成   现在时点(基准时点)的等值金额的过程;Xjs★济宁成人高考报名电话0537-2229526

3、静态投资回收期:指工程项目从开始投资(或投产),到以其净收益(净现金流量 )抵偿全部投资所需要的时间,一般以年为计算单位。Xjs★济宁成人高考报名电话0537-2229526

4、价值工程是以最低的寿命周期成本、可靠地实现产品或作业的必要功能、着重于功能分析的有组织的创造性活动。 Xjs★济宁成人高考报名电话0537-2229526

5、技术寿命指一台设备可能在市场上维持其价值的时间,即从设备开始使用到由于技术落后被淘汰为止所经历的时间。Xjs★济宁成人高考报名电话0537-2229526

三、简答题(20分)Xjs★济宁成人高考报名电话0537-2229526

1、内部收益率的含义及其求解步骤 7 分)Xjs★济宁成人高考报名电话0537-2229526

是指项目在计算期内各年净现金流量现值累计值等于零时的折现率,即NPV(IRR)=0时的折现率。或者在项目的整个寿命期内,按利率  i=IRR  计算,始终存在未能收回的投资,而在寿命期结束时,投资恰好被完全收回。换句话说,项目在寿命期内,始终处于“偿付”未被收回的投资的状况,其“偿付”能力完全取决于项目内部,故有“内部收益率”之称谓。Xjs★济宁成人高考报名电话0537-2229526

求解步骤:1)在满足i1i2    i2i1≤5%的条件下,选择两个适当的折现率 i1   i2 ,使Xjs★济宁成人高考报名电话0537-2229526

 NPV(i1)>0,NPV(i2)<0Xjs★济宁成人高考报名电话0537-2229526

  如果不满足,则重新选择i1 i2 ,直至满足为止;Xjs★济宁成人高考报名电话0537-2229526

2) 将用i1 i2、 NPV(i1)和NPV(i2)代入线性插值公式,计算内部收益率IRR。Xjs★济宁成人高考报名电话0537-2229526

2、简述用费用年值法进行设备技术更新经济分析的具体步骤(7分)Xjs★济宁成人高考报名电话0537-2229526

①计算新设备在其经济寿命条件下的费用年值。新设备的费用年值的计算就是将其经济寿命期内所发生的投资和各年的运行费用换算成与其等值的等额支付序列的年值。当然要将设备的残值扣除。     Xjs★济宁成人高考报名电话0537-2229526

    ②计算旧设备在继续使用条件下的费用年值。这时考虑的时间是旧设备还剩余的经济寿命,将其在决策点的设备残值视为设备在那一时点的投资,计算时仍然要扣除无法再使用时的残值。一般情况下,其运行费用是逐年递增的。Xjs★济宁成人高考报名电话0537-2229526

③新、旧设备费用年值的比较。如果旧设备的费用年值小于新设备的费用年值,就无需更新,继续使用旧设备直至其经济寿命;如果新设备的费用年值大于旧设备的费用年值,就需要进一步判断何时更新。Xjs★济宁成人高考报名电话0537-2229526

    ④假设旧设备继续使用1年,计算这时的费用年值并与新设备的费用年值比较,如果其值小,则保留并继续使用旧设备,否则淘汰并更新为新设备。Xjs★济宁成人高考报名电话0537-2229526

⑤当旧设备处于继续保留使用的情况下,计算保留2年的费用年值,并与新设备的费用年值进行比较,比较原则同第4步,如此循环直至旧设备被更新淘汰。Xjs★济宁成人高考报名电话0537-2229526

3、价值工程中的价值是什么,提高产品或作业价值的途径有哪些?(6分)Xjs★济宁成人高考报名电话0537-2229526

提高价值的途径:根据价值的定义,V(价值)=F(功能)/C(成本)(1分)Xjs★济宁成人高考报名电话0537-2229526

提高价值的途径主要有五种形式:(每条1分)Xjs★济宁成人高考报名电话0537-2229526

1 提高功能、降低成本      F/ C= V     2 提高功能、成本不变      F/ C= V     Xjs★济宁成人高考报名电话0537-2229526

3)功能大提高、成本略提高   F↑↑/ C= V   4 功能不变、降低成本      F/ C= V     Xjs★济宁成人高考报名电话0537-2229526

5)功能略下降、成本大下降   F/ C↓↓= V   Xjs★济宁成人高考报名电话0537-2229526

四、计算题(25分)Xjs★济宁成人高考报名电话0537-2229526

1、(5分)某公司欲在5年后投建一大型工程,此项投资总额为1000万元。现有一短期项目,每年初投资相同资金,年收益率为10%,问每年末至少要投入多少钱才能在5年后获得此建设资金?Xjs★济宁成人高考报名电话0537-2229526

已知A / F10%5)=0.1638Xjs★济宁成人高考报名电话0537-2229526

A = A`/1+i= FA / Fin/1+i  =10000×(A / F10%5/1+0.1Xjs★济宁成人高考报名电话0537-2229526

        = 10000×0.1638 /1.1 = 1489.09(万元) Xjs★济宁成人高考报名电话0537-2229526

 Xjs★济宁成人高考报名电话0537-2229526

2、(10分)某产品主要由4个零部件组成,经过专家0-1评分法得到的各零部件功能评分值及现实成本如下表,企业规定该产品目标成本为180元,根据表中资料试用强制确定法计算出功能价值系数、按功能评价系数分配的目标成本和成本降低幅度。Xjs★济宁成人高考报名电话0537-2229526

2、(10分)解:(按填对个数并视是否掌握计算方法酌情给分)Xjs★济宁成人高考报名电话0537-2229526
