$($b$)$ Determine the EOQ inventory policy $($Order quantity, Safety Stock, Reorder Point$)$ if all five retail outlets are jointly replenished? What is the average total cost per year? Table below gives the $($symmetric$)$ distance in miles between each pair of locations. Assume demands at retail outlets are independent of each other. $($Hint: To compute the least joint ordering cost, you need to first determine the best route the truck should use! $$ Use Cheapest insertion algorithm to find this route$)$
