An end item is assembled from 4 parts of type A, 2 parts of type B, and 1 part of type C. Each A is made from one part of type E and 2 parts of type F. Each E is made from one part of type G and one part of type H.

a) (5') Develop a product structure tree of the above end item. b) (6') Assume the current time is Week 0. The production lead time for a lot of the considered end-item is 2 weeks, and its net requirements over the next 8- week planning horizon are estimated as follows: 0, 0, 0, 10, 50, 40, 60, 50 Assuming that the production of the end-item is organized on a lot-for-lot basis, determine the gross requirement for level-1 items that you determined in (a). c) (4') The current inventory position of C is 20 units, and there is a scheduled receipt of 50 units at the end of the first week. Compute the net requirements for C over the considered planning horizon using your results from (b). d) (10') The current inventory position of A is 50 units, and there is a scheduled receipt of 110 units at the end of the first week. The production lead time for a lot of A is 2 weeks. Also, the setup cost for the production of a lot of A is estimated at $350 and the holding cost for this item is $2 per unit per week. Calculate the planned order release using your results from (b) above and the lot-sizing policy that is based on the Silver-Meal heuristic. a) (5') Develop a product structure tree of the above end item. b) (6') Assume the current time is Week 0.
