**Product Structure and Inventory Management****Scenario:**Given the following product structure, master production schedule, and inventory status, you are tasked with developing a gross requirements plan for items C and H. Assume the requirements for each BOM item are 1. **Objective:**- Develop a gross requirements plan for Item C.- Develop a net requirements plan for Item C.### Gross Requirements Plan Development**Instructions:**1. Review the gross requirements for Items A and H for weeks 8 to 12.2. Determine the gross requirements for their parent and child items.**Weekly Gross Requirements for Item A:**- Week 8: [Data missing]- Week 9: 100 units- Week 10: [Data missing]- Week 11: 60 units- Week 12: 160 units### Detailed Information**Period Requirements:**- **Period 8:** - Gross requirements for A: 100 units - Gross requirements for H: 90 units- **Period 12:** - Gross requirements for H: 50 units**Current Inventory and Lead Times:**- **Item A:** - On Hand: 15 - Lead Time: 1 week- **Item B:** - On Hand: 110 - Lead Time: 2 weeks- **Item C:** - On Hand: 60 - Lead Time: 2 weeks- **Item D:** - On Hand: 40 - Lead Time: 1 week- **Item E:** - On Hand: 85 - Lead Time: 2 weeks- **Item F:** - On Hand: 80 - Lead Time: 2 weeks- **Item G:** - On Hand: 65 - Lead Time: 1 week- **Item H:** - On Hand: 20 - Lead Time: 1 week- **Item J:** - On Hand: 110 - Lead Time: 2 weeks- **Item K:** - On Hand: 110 - Lead Time: 2 weeks### Diagrams**Diagram Explanation:**- **Left Diagram (Hierarchy of A):** - A splits into B and C. - B further splits into

Given information is Period 8 9 10 11 12 Gross req of A 100 60 160 Gross req of H 90 50 On hand quantity of A = 15 On hand quantity of H = 20 On hand quantity of C = 60In the product tree structures given, there are singular requirements for all the materials. It means there are no materials required twice, thrice, etc. amount of their parent material because no such specification is given. Hence, so the requirements of sub-materials will be directly equal to their parent material. Now, the gross requirements for item C as per the gross requirements of A are shown below. Period On-hand 8 9 10 11 12 Item A 15 85 60 160 Item C 60 25 60 160 Now, the gross requirements for item C as per the gross requirements of H are shown below. Period On-hand 8 9 10 11 12 Item 7 20 70 50 Item C 0 70 50 Note that there will be no on-hand requirements for item C when calculating in regard to item H because the on-hand quantity of 60 will be used in period 8 for item A. Hence, the complete gross requirement plan of item C is shown below. Period On-hand 8 9 10 11 12 Item A 15 85 60 160 Item H 20 70 50 Item C 60 25 70 60 50 160
