Question: Please note that this question has two parts (a and b). You may need to scroll the screen down, navigate left and right to see the whole problem. Clearly label your parts when answering. You are allowed three pictures for this problem. Must use pen to answer. Must show all work/steps completely in the MRP tables. One unit of A is made of two units of B, three units of C, and one unit of D. B is composed of three units of E and two units of F. C is made of one unit of E and three units of H. D is made of two units of H. All items have a one-week lead time except A, which has a two-week lead time. Assume that lot-for-lot (L4L) lot sizing is used for items A, B, C, and H, while D, E, and F require multiples of 50, 100, and 150, respectively. The company has some on-hand inventory of parts from earlier production periods: D (40), E (100), and F (150). During the week 1 the company is scheduled to receive 100 units of A, 500 units of E, 600 units of F, and 400 units of H. There are no other scheduled receipts. Gross requirements for item A are 200 units in week 5 and 250 units in week 8. a. Show the bill-of-material (product structure tree). b. Develop an MRP planning schedule showing gross and net requirements and find the necessary planned-order releases for all components.
