The following product structure tree indicates the components needed to assemble one unit of product W. Determine the quantities of each component needed to assemble 100 units of W. W A B (2) C (4) D (2) E E (2) F D (3) G (2) Answers: A = 100, B = 200, C = 400, E = 500, F = 200, G = 800, D D = 2,200Then, assume that you have the current (on-hand) inventory level with 100 As, 100 Bs, and 100 Cs. Given these on-hand inventory, determine the quantities of each component (A, B, C, D, E, F, G) needed to assemble 100 units of the end item W, and explain why. Full marks will be given only to those who describe all quantities for all components (A,B,C,D,E,F,G) correctly. Limit your explanation to less than 200 words. Hint: The answer is not simply 'the original answer minus 100 for A, B and C': You should use the product structure tree from top to bottom to count how many units are required for each component by reconstructing the tree. If a parent item has no need (i.e, already sufficient with current inventory), no components should be required for that specific parent item. For example, with the current on-hand inventory of 100 As, notice that the branches underneath A will disappear (i.e., you do not need the sub-components under A)
