The product structure of A is indicated below. The notation X(m) indicates m units of components X are required to produce one immediate parent component and LT represents the Lead time in weeks. A(1) LT: 1 B(2) LT: 1 C(3) LT: 1 D(2) F(2) LT: 2 LT: 2 a) Considering the product structure presented above and the lead-time, if you should deliver a product A at the beginning of the week 10, when should you start the production of component D? --> week: 5 (1pt) b) Considering the product structure presented above, if you have in stock: 20 units of D, 20 units of F, 15 units of C, 10 units of B, except A. How many of A could you produce? maximum of 5 A(1pt) For the following three questions, use the product structure above. The initial stock of each component is given in the table below. Suppose that there are no safety stocks and the components are ordered and delivered exactly the quantity required (lot-for-lot approach). A B D F Initial stock (units) 10 20 50 60 40 Considering the gross requirement (GR) of product A in the following planning. Each order is delivered at the end of each week Product: A Weeks LT: 1 weeks 1 2 3 4 5 6 7 8 9 Gross requirement (GR) 0 0 0 0 0 0 20 0 40 c)What is the net requirement (NR) of product A in week 7? --> NR of A in week 7 is (1 pt) d) What is the net requirement (NR) of component B in week 6 ? --> NR of B in week 6 is (1pt) e) What is the planned order release of component Fin week 3? --> Planned order release of Fin week 3 is (1pt)
