Chapter 12 Case Study: The Realco Breadmaker
1. Develop a master production schedule for the breadmaker. What do the projected ending inventory and available-to-promise numbers look like? Has Realco “overpromised”? In your view, should Realco update either the forecast or the production numbers?
A master production schedule for the bread-maker will be presented below. Demand Management Week 1 Week 2 Week 3 Week 4 Week 5 Week 6 Week 7 Week 8. Weekly demand for bread-maker is 20,000 20,000 20,000 20,000 20,000 20,000 20,000 20,000. Working days in a week is 6 6 6 6 6 6 6 6. MPS demand for bread-maker 3,333

This paper looks at the lean systems and some of the proposed changes in the supply chain.
1. What are some of the advantages of the supply chain used in the Japanese auto industry before the March 11 earthquake and tsunami? What were some of its disadvantages?
Most Japanese automakers used the lean production systems, whose main philosophy was that automakers should only produce what is needed, in necessary quantities at the right time. This system offered automakers several advantages. First, the production system significantly reduced costs for the automakers as there was little direct labor required because all the non-value added activities are eliminated. This is because parts are produced in different factories and delivered to the motor makers who join them together to complete the production process. As such, very little floor space is required as well as less warehouse space per a unit of output. There are less schedule delays as the production of vehicles is continuous depending on the demand for vehicles. Another key advantage associated with this production system is high quality because quality control measures have been integrated in the production system. Cases of defects are usually detected at the source of the parts and redone before they are added to other parts. The system gives a key competitive advantage to Japanese automakers as
