TPC Company produces paint in cans. They have found that in 9 samples of 7 cans each, the average can contains 2.05 liters of paint. The average range found over these samples is 0.24 liters. Find the control limits for X-bar and range charts.
b. XYZ company produces staplers and other items. The production cost per unit is $8 and the cost of setting up the production line for this is $60. The annual holding cost rate is 30%. The company works 250 days per year. The production rate for this product is 120 per day. If the annual demand is 20,000 units,
i. Which batch size should the company use?
ii. What is the minimum monthly cost?
iii. What is the total production time allocated to this product annually?
A process currently services an average of
59
customers per day. Observations in recent weeks show that its utilization is about 90 percent, allowing for just a 10 percent capacity cushion. If demand is expected to be
70
percent of the current level in five years and management wants to have a capacity cushion of just
4
percent, what capacity requirement should be planned?
The needed capacity requirement is
nothing
customers per day. (Enter your response rounded up to the next whole

- The ABC Company is planning a new product line and a new plant to produce the partsfor the line. The product line will include 8 different models. Annual production of eachmodel is expected to be 900 units. Each product will be assembled of 180 components.All processing of parts will be accomplished in the new plant. On average, 6 processingoperations are required to produce each component, and each operation takes an averageof 1 min (including an allowance for setup time and part handling). All processing operationsare performed at workstations, each of which includes a production machine and ahuman worker. The plant operates one shift.
