A copy machine is available 16 hours a day. On a typical day, the machine produces 152 jobs. Each job takes about 1.5 minutes on the machine, 0.5 minute of which is processing time and 1 minute is setup time (logging in, defining the job). About 25% of the jobs need to be reworked, in which the set-up time and the processing time have to be repeated once. In the remaining time, the equipment is idle. You would need to show steps and use 2 decimals in calculations.
(a) Define and calculate total waste time in minutes.
(b) Define and calculate total non-value added time in minutes.
(c) Define and calculate total value-added time in minutes.
(d) Draw a diagram to illustrate the breakdown of equipment time.
(e) What is the OEE of the equipment? (percentage, 2 decimals, i.e. 23.67%)
