Steelco needs to cool 17 pieces of steel. The weight and due date for each piece are listed in the file P08_38.xlsx. Processing and cooling a batch in the furnace takes 5 minutes regardless of the weight in the furnace. The furnace can handle up to 1000 pounds at a time. Jobs 6 and 7 (size 640 and 450, respectively) must be completed on time. How can the company minimize the total time the jobs are late?
