Question 4 The standard time to perform a certain manual work cycle is 432 min to produce a piece i. If the PFD allowance is 20% determine the normal time for the cycle 15 Marts An irregular work element whose normal time is 4.0 min has to be added to the process once in every 10 cycles. If the same PFD allowance is given to the irregular work element determine the total standard time for the process. 15 Marks) l. A worker has produced 110 units on a particular shift. Using the standard time including the irregular work element in part (1) above calculate how many standard hours of work has been achieved (s Marks) iv. The management is considering introducing a machine in an internal system to speed up the process whereby the manual work is reduced to 0.5 mins normal time. The irregular element is not needed. Assume that the PFD is 20% and the machine allowance is 10. If the standard cycle time now is 2.2 mins for the machine in the internal work system arrangement (a) find the normal time for the machine. (b) Draw the block diagram for the internal system and mark off the times ] Calculate the standard time for the cycle. (10 Marks) (Total: 25 Marks
