13. Refer to Problem 12. Assume that unusually mild weather has caused a change in the quantity and

at the start of week 8, and 100 at the start of week 9.
a. Develop a master schedule for this revised plan.
b. Determine the timing and quantities for orders for tops and bases.
c. Assume that equipment problems reduce the firm's capacity for assembling bases to 50 units
per week. Revise your material plan for bases to reflect this, but still meet delivery dates.
