问题 问答题

某企业已安装机床100台,4月份制度工作日为22日,每日制度规定两班(15.5小时),已安装机床3台,因任务不足4月份停开,计划检修项目内大、中修计划修理台时为831台时,根据原始记录汇总资料得出:计划检修项目内大、中修实际修理台时为915台时,停电、待料、设备故障等实际停开台时为815台时。 计算:(1)制度台时利用率; (2)计划台时利用率; (3)机床台时利用率。

答案

参考答案:先将计算利用率中用到的指标计算出来: (1)制度台时=制度规定开动设备数×制度规定开动日数×每日制度开动时数 =100×22×15.5=34100台时 (2)计划台时=计划开动设备数×计划规定开动日数×每日计划开动时数 =97×22×15.5=33077台时 (3)按两班制应开动台时=已安装机床台数×制度规定开动日数×15.5小时 =100×22×15.5=34100台时 (4)实际工作台时=实际开动设备数×实际开动日数×每日制度开动时数-各类实际停开台时 =97×22×15.5-915-815=31347台时 (5)制度台时利用率=实际工作台时/(制度台时-计划大中修实际停开台时) =31347/(34100-915)=94.46%(6)计划台时利用率=实际工作台时/(计划台时-计划大中修实际停开台时) =31347/(33077-915)=97.47%(7)机床台时利用率=实际工作台时/(按两班制应开动台时-计划大中修实际停开台时) =31347/(34100-915)=94.46%

In the fifteenth century in Nuremberg ,lived a family with eighteen children .They were so poor that two children ,who wanted to pursue their talent for  41  , knew their father would never be  42  able to send either of them to Nuremberg to study at the Academy.

So they tossed(掷)a coin. Albrecht Durer, the younger,  43  the toss and went off to Nuremberg .Albert went down into the dangerous 44   and ,for the next four years ,financed his brother , who did so well that his works were even better than those of most of his  45 . By the time he graduated ,he was beginning to earn  46  fees by drawing for wealthy people.

When Albrecht returned home, at dinner he drank a  47  to his beloved brother for the years of    48  that had enabled him to fulfill his  49 . He said, "Albert ,my blessed brother ,now it is your      50  to go to Nuremberg to pursue your dream ,and I will take care of you."

With tears in his eyes ,Albert held his hands close to his right cheek and said, "No ,brother. I cannot go . Look... look what four years in the mines have done to my  51  ! The bones in every finger have been  52  at least once. Lately I have been suffering from arthritis(关节炎)so badly in my right hand that I cannot even hold a  53 to return your toast ,much less make delicate lines with a pen or a brush. No ,brother... for me it is too  54  ."

Deeply moved ,Albrecht painstakingly drew his brother's  55  hands with palms together and thin fingers stretched skyward .He called his powerful drawing  56  "Hands" , to which the entire world immediately opened their hearts and later they  57 it "The Praying Hands."

The next time you see a copy of that  58  creation, take a second look. Let it be your  59  ,if you still need one ,that no one ever makes it  60   !
