10-14 Hardrock Concrete's owner has decided to increase the capacity at his smallest plant (see Problem 10-13). 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
