Identify all levels, parents, and components.b) Prepare a time-phased product structure.
Oh No!, Inc., sells three models of radar detector units. It buys the three basic models (E, F, and G)from a Japanese manufacturer and adds one, two, or four lights (component DLead times are one week for all items except C, which is two weeks. There are ample suppliesof the basic units (E, F, and G) on hand. There are also 10 units of B, 10 units of C, and 25 units ofD on hand. Lot-sizing rules are lot-for-lot ordering for all items except D, which must be ordered inmultiples of 100 units. There is a scheduled receipt of 100 units of D in week 1.The master schedule calls for 40 units of A in week 4, 60 units of B in week 5, and 30 units of Cin week 6. Prepare a material requirements plan for D and its parents) to further differentiate the models. D is bought from a domestic producer.
One unit of A is made of two units of B and one unit of C. B is made of three units of D and one unit of F. C is composed of three units of B, one unit of D, and four units of E. D is made of one unit of E. Item C has a lead time of one week; items A, B, E, and F have two-week lead times; and item D has a lead time of three weeks. Lot-for-lot (L4L) lot sizing is used for items C, E, and F; lots of size 20, 40, and 160 are used for items A, B, and D, respectively. Items A, B, D, and E have on-hand (beginning) inventories of 5, 10, 100, and 100, respectively; all other items have zero beginning inventories. We are scheduled to receive 10 units of A in week 3, 20 units of B in week 7, 40 units of F in week 5, and 60 units of E in week 2; there are no other scheduled receipts. If 20 units of A are required in week 10, use the low-level-coded bill-of-materials (product structure tree) to find thenecessary planned order releases for all components.
