QUESTION 25 (10 points) - Overall Equipment Effectiveness (OEE) 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 of setup time (logging in, defining the job) and 0.5 minute of 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. Later, specify values.

(b)[2] Define and calculate component and total non-value added time in minutes.

(c)[2] Define and calculate component and total value-added time in minutes.

(d)[2] Calculate total waste time in minutes. Give a detailed breakdown of waste time.

(e)[2] What is the OEE? What is the wasted work percentage? (%, 2 decimals, i.e. 23.67%) Note: You would need to put all calculated time values in the tree diagram.
