three. RVW (Restored Volkswagens) buys 15 used VW’s at every of two automobile auctions every week held at totally different areas. It then transports the vehicles to restore retailers it contracts with. When they’re restored to RVW’s specs, RVW sells 10 every to 3 totally different used automobile heaps. There are numerous prices related to the typical buy and transportation costs from every public sale to every restore store. Additionally there are transportation prices from the restore retailers to the used automobile heaps. RVW is worried with minimizing its complete value given the prices within the desk under.

a. Given the prices under, draw a community illustration for this drawback. (10 factors)

Restore Outlets Used Automotive Heaps
S1 S2 L1 L2 L3
Public sale 1 550 500 S1 250 300 500
Public sale 2 600 450 S2 350 650 450

b. Formulate this drawback as a linear programming mannequin. (15 factors)
(Be aware: You don’t want to unravel the mannequin.)
