Problem 11-12 (Algo) 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 2.5 gallons per hour when wide open. The faucet is the raw material input and can let material in at a rate of four 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? (Round your answer to 1 decimal place.) Maximum rate gals/hr a-2.

What are the major causes of capacity leakage? Are they avoidable? 11.10 Questions for managers Medi-Call provides personal alarm systems to the elderly and infi rm. Customers are principally those people who live alone, preferring to stay in their own homes rather than be looked after in some form of institutional care or with family. The customer has a small transmitter/receiver, which can be worn as a pendant or on the wrist like a watch. If the customer has a problem they press the button on the pendant, which activates a base station located at the customer’s telephone. The base station calls Medi-Call’s contact centre, which provides 24/7 cover to ensure maximum reassurance for its customers. Medi-Call’s agent will attempt to establish contact with the customer. Because the transmitter is so sensitive, it is possible to carry out a conversation up to 50 metres away from the base station. Medi-Call’s staff are trained to provide immediate reassurance to the…

Assume that the manufacturing process is triggered by a monthly sales forecast, which is received periodically from the marketing department in digital form. Further assume that all functional areas (work centers, storekeeping, inventory control, etc.) employ terminals that are networked to a centralized data processing function. Your system design should minimize hard-copy documents.
