The standard time for a worker to complete a certain manual work cycle and produce a piece is 4.8 min. if the PFD allowance is 20%, determine the normal time for the cycle. 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. ii. A worker has produced 100 units on a particular shift. Using the standard time including the irregular work element in part (i) above, calculate how many standard hours of work has been achieved. iii. 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 normal cycle time now is 2.2 mins in the internal work system arrangement: (a) draw the block diagram for the internal system and mark off the times (b) calculate the standard time for the machine.
