5. 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 22, 50, and 200 are used for Items A, B, and D, respectively.
