An MRP exercise is being implemented over an 8-week period and the following relevant information is provided: One (1) unit of A is made of two (2) units of B, one (1) unit of C, and two (2) units of D. B is composed of two (2) units of E and one (1) unit of D. C is made of two (2) units of B and three(3) units of E. E is made of two (2) units of F. Items B, C, E and F have one (1) week lead times; A and D have lead times of two (2) weeks.
Assume that lotfor-lot (L4L) lot sizing is used for Items A, B and F; lots of size fifty (50), one hundred (100) and one hundred (100) are used for Items C, D and E respectively. Items C, E and F have on-hand (beginning) inventories of ten (10), fifty (50) and one hundred (100), respectively; all other items have zero beginning inventory.
We are scheduled to receive ten (10) units of A in Week two (2), fifty (50) units of E in Week one (1), and also one hundred (100) units of F in Week one (1). There are no other scheduled receipts.
a) Draw the product structure tree with low level coding
