Production & Inventory Control
Case study 4
(Total 10 points)
Question 1: Why does it make sense to address the problems of planning and control in a manufacturing system with a hierarchical system? What would a non-hierarchical system look like?
Question 2: Give some possible reasons why MRP has spawned elaborate hierarchical planning structures while JIT has not.
Question 3: What is the difference between causal forecasting and time series forecasting?
Question 4 In this era of rapid change and short product lifetimes, it is common for process
technology to be used to produce several generations of a product or even completely new
products. How might this fact enter into the decisions related to capacity/facility planning?
Question 5: How must the capacity/facility planning and aggregate planning be coordinated?
What can happen if they are not?
