Scheduling

Before Class:

Materials Requirements Planning

2. What does 'MRP' stand for?

3. What is the difference between independent demand and dependent demand? Which type does MRP consider?

4. What forms of operating organizations are best served by MRP?

JIT

1. How does JIT differ from MRP?

2. Read textbook chapter 17: Just In Time Systems.

Think About It

1. What are the weaknesses of MRP?

2. What are the primary inputs and outputs for an MRP system?

3. What is the importance of the master production schedule in an MRP system?

4. You should be familiar with the terms used in MRP such as planned order release and scheduled order receipts.

5. You should be able to draw the product structure tree for a product situation and then determine the units of components needed and the time needed. This will result in knowing the order releases (time and quantity) of components.

6. What are the weaknesses of JIT?

7. What are the "seven zeros"?

8. What did you learn from the John Deere "Styro" video?

9. You should be able to compare and contrast MRP versus JIT and identify which approach is more suitable in different situations.
