Figure 1.1 shows the process sequence and its respective capacity for making the F104XM product. The company works 5 days a week, single shift 8 hours per day.

i) Determine which process becomes a bottleneck when making the above F104XM product. Give your reason.

ii) The capacity of the above bottleneck process is increased by adding one more parallel station. Calculate the maximum weekly capacity (effective) for the overall process.

iii) If the monthly demand for the above product is 800 units, determine how much the total overtime cost the company should bear. Assume that the average overtime cost is RM 25/hour and there are 4 weeks in a month.
