Based on Muckstadt and Wilson (1968). PSI believes it will need the amounts of generating capacity (in millions of kwh) shown in the file P06_80.xlsx during the next five years. The company has a choice of building (and then operating) power plants with the capacities (in millions of kwh) and costs (in millions of dollars) shown in the same file. Determine how to minimize the total cost of meeting PSI’s generating capacity requirements for the next five years.
