Management must make more detailed capacity requirements planning to determine whether these more specific capacity requirements can be met and some adjustments in the master production schedule may be required.

Trang 2622. A regenerative MRP system is one that is updated continuously every time there is a schedule change. FALSE

Trang 4574. Given the following information, construct a product tree diagram and develop a material requirements plan that will lead to 400 units of product P being available at the start of week 7.
Trang 4675. Develop a material requirements plan for end item P and its components, given the tree below. Assume that all lead times are one week, and that lotforlot ordering is used except for item F, which is ordered in multiples
Trang 4776. Given the following data, construct a material requirements plan which will result in 100 units of Parent #1 (P1) at the beginning of week 6, and 200 units of Parent #2 (P2) at the beginning of week 8:
Trang 48(A) If 50 units of Alpha are to be assembled, how many additional units of S will be needed? All parts can be ordered using lotforlot ordering, except M, which must be ordered in multiples of 40 units. [Hint: You don't need to do an MRP plan.]
(B) An order for 100 units of Alpha is scheduled to be shipped at the start of week 9. When is the earliest that any particular component must be started so that the order for Alpha will be ready to ship? [Hint: You don't need to do an MRP plan.]
A) Gross requirements for S are 200 units, leading to net requirements for S of 100 units
B) Additional units of W will have to be started at the beginning of week 1
Feedback: If 50 units of Alpha are to be assembled, then gross requirements for K will be 50 and gross
requirements for M will be 100. Net requirements for K will be 20 and net requirements for M will be 70. K is ordered lotforlot, so its net requirements lead to gross requirements for S of 40 units. M is ordered in multiples
of 40, so its order quantity of 80 units will lead to gross requirements for S of 160 units
The longest sum of lead times is 8 (Alpha's 2 weeks + H's 4 weeks + W's 2 weeks). This means that additional units of W will have to be started at the beginning of week 1
