QUESTION 21 (10 points) ‐ Overall Equipment Effectiveness (OEE)

QUESTION 21 (10 points) Overall Equipment Effectiveness (OEE) A copy machine is available 20 hours a day. On a typical day, the machine needs to process 360 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 30% 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)[2] Define and calculate total waste time in minutes. (b)[2] Define and calculate total non-value added time in minutes. (c)[2] Define and calculate total value-added time in minutes. (d)[2] Draw a diagram like Figure 8.1 (page 214) to illustrate the breakdown of equipment time Alternatively, you can opt to draw a tree diagram to show the breakdown of equipment time. (e)[2] What is the OEE of the equipment? (percentage, 2 decimals, ie. 23.67%)
