Hardrock Concrete's owner has decided to increase the capacity at his smallest plant. Instead of producing 30 loads of concrete per day at plant 3, that plant's capacity is doubled to 60 loads. Find the new optimal solution using the northwest corner rule and stepping-stone method. How has changing the third plant's capacity altered the optimal shipping assignment? Discuss the concepts of degeneracy and multiple optimal solutions with regard to this problem.
