(30) A defense contractor provides the latest state-ofthe art fighter jet to the US. miliary. The end-product is assembled from the following component items in the nal assembly stage with lead times in weeks denoted in parentheses: fuselage (2), cockpit (3), right wing and left wings (2), tail (3) and two engines (4). The left and right engines are identical. The two wings are not. The contractor uses sub-contractors for all components except the fuselage and cockpit, so only the fuselage and cockpit components are considered here. The cockpit has an avionics suite (4) plus the cockpit structure (2). The fuselage has the surface metal (6) as well as 2 structural support sets (4) and a landing gear set (3). The surface metal consists of numerous pieces but can be considered as one component here for simplicity. The same is true of the structural supports. Lead time for the end-product is 1 week. a. (6) Specify the BOM table with component name/ID, level, parent-child association, quantity and lead time. b. (6) Draw a hierarchy diagram for the BOM. c. (6) In Week 8, gross requirements for the end-product are 6. On-hand inventory in Week 7 is 2 with no scheduled receipts. What are the net requirements for Week 8 and the associated timed requirements (including week)? d. (6) Now consider the following scenario. In Week 8, gross requirements for the end- product are 9. On-hand inventory in Week 7 is 0 with scheduled receipts of 2. Assume no initial on-hand inventory or scheduled receipts for engines. What are gross requirements, net requirements and timed requirements for engines (including period). c. (6) What is the minimum manufacturing lead time
