Chapter 5, Problem 13P
Quick Stop Pharmacy is a small family-owned, drug-compounding business in Portland, Oregon, that is trying to perfect its customer service operations. The owner, John Suleiman, wants to maximize the productivity of his staff as well as serve customers well. One area of concern is the drive-thru operation during the 7:30–8:30 morning rush hour. The process of fulfilling an order is as follows:
- If all the steps are handled by one employee, how many patients could be served per hour?
- If James wants to process 30 patients per hour, how many employees will he need?
- How many stations are required using the longest work element decision rule?
- Using the solution developed in part (c), which station is the bottleneck and how large is its capacity cushion?

XOX Corporation's management keeps track of the time it takes to process orders. During the most recent month, the following average times were recorded per order
Wait time 15. 6
Inspection time 0.8
Process time 1.6
Move time 0.7
Queue time 3. 9
1. Percentage of manufacturing cycle time spent on non-value-added activities
2. Compute the delivery cycle time in days
4. CWD Business systems maintains a successful Telecom sales department for Top up call
credit in which a clerk takes orders by telephone. If the clerk is occupied on one line,
incoming phone calls to the department are answered automatically by an answering
machine and asked to wait. As soon as the clerk is free, the party that has waited the
longest is transferred and answered first. Calls come in at a rate of about 15 per hour. The
clerk is capable of taking an order in an average of 3 minutes. Calls tend to follow a
Poisson distribution, and service times tend to be exponential. The clerk is paid $15 per
hour, but because of lost goodwill and sales, CWD loses about $30 per hour of customer
time spent waiting for the clerk to take an order.
Part B
CWD is considering adding a second clerk to take calls. The store would pay that person the
same $15 per hour.
Using appropriate formula for the multiple channel model, answer the following questions:
a. What is the probability that no…

Ford have seven production lines in their manufacturing plant for their automotive parts where each production line produces 120, 100, 80, 116, 77, 94, 112 output per day. (a) As the Production Manager at Ford, you are required to submit the daily report of the production plant. Calculate the mean, median, and mode from the data based on the output that has been provided. (b) Also calculate the three critical parameters for measuring spread in the following ways: Range Variance Standard Deviationarrow_forwardL. Winston Martin (an allergist) has an excellent system for handling his regular patients who come in just for allergy injections. Patients arrive for injection and fill out a name slip, which is then placed in an open slot that passes into another room staffed by one or two nurses. The specific injections for a patient are prepared, and the patient is called through a speaker system into the room to receive the injection. At certain times during the day, patient load drops and only one nurse is needed to administer the injections. Let’s focus on the simpler case of the two—namely when there is one nurse. Also, assume that patients arrive in a Poisson fashion and the service rate of the nurse is exponentially distributed. During this slower period, patients arrive with an interarrival time of approximately three minutes. It takes the nurse an average of two minutes to prepare the patients’ serum and administer the injection.a. What is the average number you would expect to see in Dr.…arrow_forward
- I submitted this question a couple days ago. However, I am still a little confused. Here was the original question: Collins Little Company has a staff of 4 employees, each working 8 hours per day at a rate of $20/hour. Their overhead expenses are $200/day. Collins processes and closes on 12 titles each day. They are considering purchasing a computerized title search system that will allow the processing of 20 titles per day. With the new system, they could cut their staff to 2 employees working the same hours at the same pay, but their overhead expenses would double to $400 per day. 1. Compute the labor productivity with the old system (in titles / hour). 2. Compute the labor productivity with the new system (in titles / hour). 3. Compute the multifactor productivity with the old system (in titles / dollar). 4. Compute the multifactor productivity with the new system (in titles / dollar). One of the answers is: Labor Productivity = 12/(4*8) Another is: Labor Productivity =…arrow_forwardRideShare offers short-term rentals of vehicles that are kept in small lots in urbanneighborhoods with plenty of potential customers. With one lot, it has eight cars. Theinterarrival time of potential demand for this lot from its base of customers is 40 minutes.The average rental period is five hours. If a customer checks availability of vehicles in thislot online and finds that they are all rented for the desired time, the customer skips rentingand finds alternative arrangements. However, because customers pay a monthly fee tosubscribe to this service, RideShare does not want customers to be disappointed too often.a. What is the offered load?b. What is the implied utilization?c. What is the capacity of the process (rentals per hour)?d. What is the probability that all eight cars are rented at the same time?e. How many customers are served every hour?f. What is the utilization of the cars?g. How many cars should it have in this lot to ensure that it serves at least 90 percent ofdemand?arrow_forwardA company that makes a product recently purchased some new equipment that reduces the labor content of the jobs needed to produce the product. Prior to buying the new equipment, the company used six workers, who produced an average of 90 units per hour. Workers receive P35 per hour and machine cost was P2,000 per hour. With the new equipment, it was possible to transfer one of the workers to another department, and equipment cost increased by P500 per hour while output increased by four units per hour. Compute labor productivity under each system. Use units per worker per hour as the measure of labor productivity.arrow_forward

It would take about 15 minutes before a customer will be entertained due to the number of customers being served by the sales representative and only about 4 sales representatives are on duty every day.- The sales representative will take down the customer’s order in the order slip with corresponding prices. On some cases, she will ask the person in-charge in the warehouse if the items are available. She then forwards the order slip to the cashier.- The cashier would sum-up again manually the order slip from the sales representative to check the accuracy of the footing of the totals as well as the prices indicated. This would take about 10 minutes, depending on the bulk of the order being placed.- The official receipt will be printed and will be given to the…arrow_forwardA campus deli serves 300 customers over its busy lunch period from 11:30 a.m. to 1:30p.m. A quick count of the number of customers waiting in line and being served by thesandwich makers shows that an average of 10 customers are in process at any point intime.
