Question
We want to make a time study on a worker-machine cycle. To do that, we observe times via
the snapback method. This cycle comprises three elements: x, y, and z. Elements x and y are
worker-controlled and performance rated at 100%. Element z is machine-controlled. Besides,
it is given that elements y and z are performed at the same time. The PFD allowance = 10%
and the machine allowance = 15%. At each cycle, the system produces one work piece.
Q: Find (a) the normal time and (b) standard time for the cycle.
