10. Customers arrive an average of 8 per hour and an average of 12 customers can be served in an hour. Assume this is an M/M/1 model. (Noteshaper Quick Start #18 - #20) what is the system utilization? what is the average length of the line? what is the average number of customers in the system? what is the average amount of time spent waiting in the line? what is the average amount of time a customer spends in the system? what is the probability of no customers in the system? 11. Customers arrive at a ferry ticket office at the rate of 18 per hour on Monday mornings. This can be described as a M/M/1 model. Selling the tickets and providing general information takes an average of 2 minutes per customer. One ticket agent is on duty on Mondays. (Noteshaper Scenario #34) a. What is the average length of the line on Monday mornings? b. On average, how long does a customer wait to buy a ticket on Monday mornings (in minutes)? c. How long does it take to successfully buy a ticket on Monday…

The dry cleaning station has three cleaning devices, r = 3. The intensity of the flow of visitors λ = 6 (person / h). Intensity of serving visitors with one device µ = 3 (person / h). The average number of visitors leaving the queue without waiting for service, ν = 1 (person / hour). Find the absolute throughput of the dry cleaning point.

[Queuing Theory - Operations Research] RBMC Industry manufactures a special printing according to customer specifications with respect to the number of sheets the machine can produce per hour. With this, there is a $50 increase in the production rate x. A shop owner is considering buying one of these machines. From his past experiences, the owner estimates that the arrival rate is three per hour and each order averages 500 sheets. Contracts signed by the owner, and the customer says that there will be a penalty of 10$ per late order per hour. It is assumed that the actual production time is exponential. (a) Formulate the cost model as a function of the production rate x. (b) Determine the optimal production rate the owner should specify in his purchase of the machine from RBMC. Hint: Get the derivative of the cost function.
A customer survey concluded that timely departure of your buses is the number two priority of passengers, ahead of comfort, price, food, and other factors. Only safety was rated higher than timeliness. You believe that your bus company and your competitors are offering about the same level of service, safety, and price. Time seems to be the only competitive edge. As the general manager, you have just announced to your drivers, dispatchers, employees, and customers that all buses will depart on time. After one month of implementing this on-time policy, you notice that if the buses are not full, many drivers refuse to leave on-time in spite of the warnings they get from the dispatchers. The sales department is also lukewarm to your on-time program. Revenues have declined as a result of buses leaving on time but half full. Your drivers are protesting since the on-time policy is affecting their pockets. Their commissions are based primarily on the load factors of each trip. They find it…
A toll tunnel has decided to experiment with the use of a debit card for the collection of tolls. Initially, only one lane will be used. Cars are estimated to arrive at this experimental lane at the rate of 750 per hour. It will take exactly four seconds to verify the debit card. How much time would you expect a customer to wait in line, pay with a debit card, and leave? Note: Do not round intermediate calculations. How many cars would you expect to see in the system? Note: Round your answer to 2 decimal places.
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…
