Check m Problem 14.5 To simplify data handling to include the receipt of orders that have actually been placed in previous periods, the following six-level scheme can be used. A number of different techniques are used in practice, but the important issue is to keep track of what is on hand, what is expected to arrive, what is needed, and what size orders should be placed.) One unit of A is made of three units of B, one unit of C, and two units of D. Bis composed of two units of E and one unit of DC is made of one unit of B and two units of E. E is made of one unit of F. Items B, C, E, and F have one-week lead times: A and D have lead times of two weeks. Assume that lot-for-lot (L4L) lot sizing is used for Items A, B, and F; lots of size 58, 58, and 208 are used for Items C, D, and E, respectively. Items C, E, and F have on-hand (beginning) inventories of 18, 58, and 158, respectively, all other items have zero beginning inventory. We are scheduled to receive 18 units of A in Week 2,58 units of E in Week 1, and also 58 units of F in Week 1. There are no other scheduled receipts. If 38 units of A are required in Week 8, use the low-level-coded bill of materials to find the necessary planned order releases for all components. Required: Develop an MRP planning schedule showing gross and net requirements and order release and order receipt dates.
