Copy Cantik (CC) is a fledging copy center in downtown Parit Raja run by two college students. Currently, the equipment consists of two high-speed copiers that can be operated by one operator. If the students work alone, it is conceivable that two shifts per day can be staffed. The students each work 8-hours a day, 5 days a week. They do not take breaks during the day, but they do allow themselves 30 minutes for lunch or dinner. In addition they service the machines for about 30 minutes at the beginning of each shift. The time required to set up for each order varies by the type of paper, use of color, number of copies, and so on. Estimates of setup time are kept with each order. Since the machines are new, their efficiency is estimated at 90 percent.
