A copy machine is available 16 hours a day. On a typical day, the machine needs to process 240 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)[1] Draw a tree diagram to show the breakdown of equipment time.

(b)[2] Identify and calculate component and total non-value added times in minutes. (c)[2] Identify and calculate component and total value-added times in minutes. (d)[2] Calculate total waste time in minutes. Give a detailed breakdown of total waste time. (e)[1] Put all time values you have just calculated in the tree diagram. (f)[1] What is the OEE of the equipment? (percentage, 2 decimals, i.e. 23.67%) (g)[1] What is the percentage of wasted work time? (i.e. 23.67%)
