A new facility will be designed to do all the welding for three products: A, B, and C. The per unit welding time for each product (using one welding line) is 20, 40, and 50 seconds respectively. Suppose the forecast annual demands for the three products are 450, 000 for A, 360,000 for B, and 240,000 for C. Show work/explain how each answer was found.
a) What is the total welding line time required per year?
b) The company believes that a welding line working two shifts per day, five days per week could operate approximately 220, 000 minutes per year. How many welding lines would be needed in the new facility being designed?
c) What is the utilization of the welding lines you recommended in (b) above?
