The bathtub theory of operations management is being promoted as the next breakthrough for global competitiveness. The factory is a bathtub with 40 gallons of capacity. The drain I the outlet to the market and can output 2.0 gallons per hour when wide open. The faucet is the new material input and can let material in at a rate of four gallons per hour. (Assume the bathtub is empty to begin with): A1. What is the maximum rate (gallons per hour) at which time the market can be served is all values are set to maximum? (Round to 1 decimal place) A2. If the faucet is running at maximum and the drain is wide open, in how many hours will the bathtub completely fill and start to overflow (round to 1 decimal place) B. suppose that, instead of a faucet, a five gallon container is used for filling the bathtub (assume a full container is next to the tub to begin with); it takes two hours to refill the container and return it to the bathtub. What is the average output rate (gallons per hour)? (1 decimal place)
