The bathtub theory of operations management is being promoted as the next breakthrough for global competitiveness. The factory is a bathtub with 60 gallons of capacity. The drain is the outlet to the market and can output 6.0 gallons per hour when wide open. The faucet is the raw material input and can let material in at a rate of eight gallons per hour. Now, to test your comprehension of the intricacies of operations (assume the bathtub is empty to begin with): a-1. What is the maximum rate (gallons per hour) at which the market can be served if all valves are set to maximum

Each container is cut from the mould once the plastic has cooled and hardened. unit-level 2 patents are obtained for each new type of container mould. facility-level 3. plastic resins are used as the main direct material for the containers. product-level 4. a plant manager oversees the entire manufacturing operation. facility-level 5. the sales force incurs travel expenses to attend various trade shows throughout the country to market the containers. product-level 6. each container product line has a product line manager. product-level 7 the extrusion machine is calibrated for each batch of containers made. facility-level 8. each type of container has its own unique moulds. unit-level 9. routine maintenance is performed on the extrusion machines. facility-level 10. rent is paid for the building that houses the manufacturing processes. classify each activity as either unit-level, batch-level, product-level, or facility-level.
