QUESTION 25 (10 points) - Overall Equipment Effectiveness (OEE) A copy machine is available 15 hours a day. On a typical day, the machine needs to process 320 jobs. Each job takes about 1.5 minutes on the machine: 1 minute is setup time (logging in, defining the job) and 0.5 minute of which is processing time. 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 decimal places. (a)[2] Draw a tree diagram to show the breakdown of equipment time. (b)[2] Define and calculate components and total non-value added time in minutes. (c)[2] Define and calculate components and total value-added time in minutes. (d)[2] Calculate total waste time in minutes. Give a detailed breakdown of waste time. (e)[O] Put all time values you have just calculated in the tree diagram. (f)[2] What is the OEE of the equipment? What is the percentage of idle time in total available time? (percentage, 2 decimals, i.e. 23.67%)
