) The continuous stopwatch timing method was used to obtain the observed times for a worker-machine task. Only one cycle was timed. The data are recorded in the table below. The times are listed indicate the stopwatch reading at the end of the element. Elements a, b, and d are worker-controlled elements. Element c is machine controlled. Elements a and d are external to the machine-controlled element, while element b is internal. Every four cycles, there is an irregular worker element that takes 1.32 min rated at 100% performance. For determining the standard time, the PFD allowance is 15% and the machine allowance is 30%. Determine a. The normal time b. Standard time for the cycle c. If worker efficiency is 100%, how many units will be produced in one 8-hour shift? d. If the actual time worked during the shift is 6.86 hours, and the worker performance is 125%, how many units will be produced?
