with the following data I need some help with the questions 1-5
The following, continuous time study was done by a collegue, but not finished. He told you that the operator was below average, working at about 85% for elements controlled by the operator. You also know that the operator PF4D allowance for this type operaton is about 15% which is applied to all elements. + in Continuous Time Study Machine Cycle Unload Load 10 10 NOON RT TRI 17 10 271 32 43 9 52 58 691 7 76 139875 10231 8 31 38 5541 55 11 8.2 100% 85% 0.15 0.15 | 0.1294 0.0820 7 .72797527 | 12.19512195 12 13 14 15 16 TOTALS 17 NO.

Complete the calculations for this time study. Which of the following is nearest the standard time for the full operation. 12. If you have to complete 1.000 of these units per day, in a single shift, how many of these operations must you have going? Hor could be asked for the output in parts per minute. 2 5 3. When an operator works at 100%, what is the machine 4. What is the operator utilization rate? utilization? A. Less than 50% A. Leos than 5016 B. 50% to 75% B. 50% to 75% C. 76% to 85% C. 76% to 85% 46 D. 36% to 95% D. 86% to 95% 47 E over 95% 45 5 . If this is a small bench job takes very little room) is this job a good candidate for a single operator to run two machines? You may want to run 49 some calculations before you answer this 50 A Yes, definitely the would cut the number of machines requred in half. B. Yes, but only if the resulting machine idle time does not contas much as the man saved. 51 C. Yes, it the machines are not existing and have to be purchased 52 D. Only if the machines can be set up to provide mirror image motion for the operator L. No, the operator could not keep up with the automatic cycles. 53 The following, continuous time study was done by a collegue, but not finished.
