supply. Answer this question by creating two columns that capture this information. 2. Assume that it takes year to obtain the starter "twigs" and plant a batch of trees, and another 2 years to grow the fees. How many trees should management consider a minimum level (a reorder point) that would trigger starting the cycle to grow a type of tree? In answering this question, assume that management wants to have a 90 percent service probability while going through each planting cycle. Answer this question relative to the number of trees and years-of-supply for the trees. 3. Management does not use an economic criterion, like EOQ, to determine planting quantity. Rather, they have stated that they want to plant a minimum of a year's worth of high-volume and two years' worth of low volume trees at a time. The idea is to order the year's supply target plus an amount needed to make up the difference between the minimum and current inventory position. For those tree types that are below the minimum level (calculated in part 2), calculate a proposed planting quantity. Create an additional column in the table for the proposed planting quantity.
