Consider an engine line that normally produces A engines per 8-hour working day during a month of 20 working days. These engines are sent to a final assembly plant that makes A cars per day on average. Suppose during one month the assembly plant makes A - AA cars every odd numbered day and A+ AA every even numbered day. Suppose that there are W production line workers at the engine plant and their labor cost (including overhead) is $80/hr for regular hours and $120/hr for overtime. Suppose also that there is nothing else for a worker to do on a regular day when the daily quota is reached before 8 hours, but the company still have to pay the worker for a full day. Let A = 100, AA = 10 and W = 60. The engine plant management never heard of the Toyota Production System and they decided to always make exactly A cars every day. There is a storage buffer for engine inventory between the engine plant and the assembly plant. What is the minimum size the buffer would have to be so that the buffer would never be empty? If the buffer is that size, what is the average number of engines in the buffer? If the inventory holding cost is $10 per engine per day, what is the average daily cost of inventory? What is the average daily cost of labor? What is the total cost of labor + inventory?
