HW Problems: Chapter 14, Material Requirements Planning Problem 1: The Desk Corporation makes two versions of the same basic file desk, the TOL (Top-of-the-line) with 2 drawers and the HQ (High-quality) one set of drawers. The TOL and HQ use one unit each of the same frame (A). The drawer assemblies are different (2 units of B for each TOL and 1 units of F for each HQ). Both drawer assemblies B and F use one unit of the same drawer frame assembly (C) for each drawer assembly. Further, the drawer assembly B for the TOL desk uses one sliding assembly (D) that requires 6 bearings (E), and the drawer assembly F for the HQ cabinet uses one sliding assembly (G) and each G requires only four of the same bearings (E). Develop a material structure tree for the TOL and the HQ Desks. Problem 2: Develop a formula for each material's gross requirement Item Gross Requirements A B D E F G A Problem 3: Develop net material requirements plan for the TOL and HQ Desks Item Scheduled Receipts Available Lead time Week #1 = 200 200 2 B None 550 1 C Week #1 =600, Week #2 = 600 800 3 ID Week #1 = 200 100 1 E Week #1 = 3000, Week #2 =3000 3000 2 IF Week #1 =800 150 2 G Week #1 - 500 1 Master production schedule Week: 1 2 3 5 6 7 8 MPS for TOLI 50 20 40 60 90 180 MPS for HQ 100 200 200 200 300 4 1 31415161718) Item LT Week: Gross requirement Scheduled receipts Projected on-hand Net Requirement Planned receipts Planned order releases LT 1 314151617181 Item Week: Gross requirement Scheduled receipts Projected on-hand Net Requirement Planned receipts Planned order releases Item LT Week: Gross requirement Scheduled receipts Projected on-hand Net Requirement Planned receipts Planned order releases Item LT Week 1 Gross requirement Scheduled receipts Projected on-hand Net Requirement Planned receipts Planned order releases Item LT Week: 12 Gross requirement Scheduled receipts Projected on-hand Net Requirement Planned receipts Planned order releases 1 Item Weck: Cross requirement Scheduled receipts Projected on hand Net Requirement Planned receipes Planned order releases Item Work Gross requirement Scheduled receipts Projected on-hand Net Requirement Planned receipts Planned order releases
