A cоmpаny hаs pоwer generаtiоn on site at one of its remote plants using gas turbines.  Currently they have enough capacity to generate 750 MW of power.  However, their demand is expected to go up incrementally over the next 5 years as detailed in the table 1 below.  The company can buy capacity in units of 10, 25, 50 or 100 MW generators.  The cost is substantial and they want to plan ahead for the next 5 years so that can budget appropriately for any generators they will plan on purchasing.  The NPV all purchase options from year 1 to year 5 are listed in table 2 below.  Formulate a linear program that determines the low cost procurement strategy that ramps up the current 750 MW capability over the next five years without any anticipated shortages.  Table 1 Year   1 2 3 4 5 Minimum Capacity in MW 780 860 950 1060 1180   Table 2 Gen.  Cost each Year ($1,000s) Gen.
