Problem 11-12 (Algo)The bathtub theory of operations management is being promoted as the next breakthrough for global competitiveness. The factory isa 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. Thefaucet is the raw material input and can let material in at a rate of four gallons per hour. Now, to test your comprehension of theintricacies 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 youranswer to 1 decimal place.)Maximum rategals/hra-2. If the faucet is running at maximum and the drain is wide open, in how many hours will the bathtub completely fill and start tooverflow? (Round your answer to 1 decimal place.)Number hours b. Suppose that, instead of a faucet, a four-gallon container is used for filling the bathtub (assume a full container is next to the tub tobegin with); it takes two hours to refill the container and return it to the bathtub. What is the average output rate (gallons per hour)?(Round your answer to 1 decimal place.)Average output rategals/hr

Given data is as follows: The capacity of the tub is given as 60 gallons and the output when wide…

Answered: a-1. What is the maximum rate (gallons…

Scenario E.1 SimQuick is being used to simulate the following bank process: Entrance Door Buffer Line Work Station Teller Buffer Served Customers Customer arrivals at the Entrance Door of the bank with an average time between arrivals of 2.5 minutes. The Line Buffer holds 6 customers. If a customer arrives and the buffer line is filled, the customer leaves. The Work Station Teller's processing time per customer is normally distributed, with a mean of 3.0 minutes and a standard deviation of 0.5 minutes. The Served Customer Buffer in the flow chart is used to count the number of customers processed during the period simulated. A 2-hour period was simulated. The SimQuick simulation is run, and the results are as follows: Overall Element Types Element Names Statistics Means Entrance Door Objects entering process 41.80 Objects unable to enter 6.23 Service level 0.87 Buffer Line Objects leaving 37.83 Final inventory 3.98 Minimum inventory 0.00 Maximum inventory 5.85 Mean inventory 3.08 Mean…

Ashley’s department store in Kansas City maintains a successful catalog sales department in which four clerk takes orders by telephone. If four clerks are occupied on four-lines, incoming phone calls to the catalog department are answered automatically by a recording machine and asked to wait. As soon as the clerk is free, the party that has waited for the longest is transferred and answered first. Calls come in an average of 3 minutes. The clerk is capable of taking an order in an average of 10 minutes. Calls tend to follow a Poisson distribution, and service times tend to be exponential. a. λ= μ= b. Calculate P0 c. How many callers, on average, are waiting to place an order under the current operating system?

erex Corporation is a global manufacturer of aerial work platforms and materials processing machinery. They design, build and support products such as large lifting equipment used in construction. The company makes most pieces to order and customizes them to meet customers’ unique preferences.Terex maintained a manual system for yard management at their transfer centre in Washington that is always full of lifting equipment, which generated excessive costs for what should have been a relatively simple process of locating customers’ units to prepare them for delivery. A wallboard and sticker system was a low-tech solution for identifying equipment items in the yard at Terex. While inexpensive in itself, the solution cost around six minutes every time an employee had to locate a unit in the yard. It also required a considerable number of hours to be spent each month taking physical inventories. After a successful pilot, the company approved a new solution, replacing stickers, yard maps,…
Please do not give solution in image format thanku The flow rate through a process is 0.5 flow units per minute. The number waiting for the process is 1. The time to do the activity in the process is 1 minute. This is a stable system. The average amount of time a flow unit spends waiting for the activity and doing the activity = ______. Enter one integer (which can be 0) and ONE decimal, so the answer looks like X.X. Any of the Xs can be a 0.
