The bullwhip measure for the manufacturer is

Consider a three$-$firm supply chain consisting of a retailer, manufacturer, and supplier. The retailer's demand over

an $8-$week period was $110$ units each of the first $2$ weeks, $190$ units each of the second $2$ weeks, $290$ units each of the

third $2$ weeks, and $410$ units each of the fourth $2$ weeks. The following table presents the orders placed by each firm in

the supply chain. Notice, as is often the case in supply chains due to economies of scale, that total units are the same

in each case, but firms further up the supply chain $($away from the retailer$)$ place larger, less frequent, orders.
