A company that supplies gasoline to a city has recorded the weekly usage (tons/week) for the past 3 years. The file BA3653GasolineRecord.xlsx contains this record. (c) In general, the company delivers the demanded gasoline to customers that store it in their own facilities. However, the company would like to obtain its own storage tanks to better handle variability. The company has identified several solutions: a 500 ton, a 1000 ton, a 2000 ton and a 3000 ton system, with each tank being proportionately more expensive as its size grows. Given your predictions and the expected variability, what size of tank would you choose? (d) Reaching the city is sometimes hazardous due to weather conditions. Even with these challenges, the company estimates that the most that shipments to the city may be delayed is 1 week. Given this information, which tank choice (of those in part c) do you think would be appropriate? week demand (tons)
