The fundamentals of production planning and control by Stephen N. Chapman
1.) What do you think should happen if you were asked to allocate some inventory for R&D, but by doing so you would drop below safety stock levels?
2.) Product "X" has the product structure given below. In addition, relevant details for each component are given.
a. Complete the Master Schedule and create MRP records for each of the components.
b. Suppose the supplier for the 600 part "C" scheduled for week 1 notifies you that an equipment problem will prevent them from shipping the parts until week 3. What are the implications? Describe ALL possible options open to you in this case.
Product "X"
On hand = 30
Safety Stock = 0
Demand Time Fence = 2
Planning Time Fence = 10
