TABLE 2 Operation time 8 hours/day/225 days/year 7500 per batch Batch size Scrap rate 4% Cycle time 3 sec Set-up time 2 hours Availability of the machine 100% [6 marks] [6 marks] c. The company is expanding it shop floor operation to fulfill more demand for producing three new t-shirt type: W, X and Z.
