生产作业管理第三次作业

一、填空题：（共10分）

1、设有某辆使用了u年的汽车，其运行维护费用率为每年400u元，如果想更换一辆新汽车，需花费10000元，则该车的经济更换年限为 7 年。

二、计算题：（共40分）

1、已知某快餐店的平均服务率m=60人/小时，平均到达率=45人/小时

求：快餐店空闲的概率、平均利用率、顾客平均等待时间

解：（1）快餐店空闲的概率 =1-45/60=25%

（2）平均服务率= 利用率= =45/60=75%

（3）顾客平均等待时间 =45/[60*(60-45)] =3分钟

2、对某零件的日需求量D=24000件/天，标准容器放置该零件数量为b=100件/箱，每天试行一班制，8小时为一工作日。

已知：Tw=1小时，Tp=0.5小时，Aw=Ap=0.2，求所需传送看板数和生产看板数。

解：

Nm=24000/100 * 1/16 *（1+0.2）=36个

Np=24000/100 * 1/16 *（1+0.2）=18个

三、匹配题（共10分）

直方图评定产品质量时可以平顶产品的总体质量，因此广泛用于实践，请将下述关于直方图形状与分析结果，按照匹配的原则用直线联系起来。

双峰形=两个不同分布混合。如有差别的机床或材料生产的产品混合。需分层后再作图

锯齿形=多属作图过程中分组过多或测量读数有误

孤岛形=表明工序质量有异常，原材料编号，短期不熟练工人替班或测量有误 平顶形=生产过程中缓慢的变动倾向因素引起的，如工具磨损、操作者疲劳

因为无法连线，故用此方式，望海涵
