The standard models contribute $20 each and the deluxe $30 each to profits. Because the company produces other items that share resources used to make the dishwashers, the stamping machine is available only 30 minutes per hour, on average. The motor installation production line has 60 minutes available each hour. There are two lines for wiring, so the time availability is 90 minutes per hour. Write the formulation for this linear program. What are the optimal daily production quantities of each product and the optimal daily profit?
You are asked to assess the current service model for a manufacturing line featuring 8 machines. Based on empirical data you have determined that machines have a 20% likelihood of being down and in need of repair. There are currently 2 workers capable of running and repairing machines. Each of the 8 machines can produce 18 units/hour. The overhead for running each of the 8 machines is $700 per day per machine. Each operator is paid at an hourly rate of $16. [You can assume an 8-hour work day]
a. Determine the total amount of lost work time.
b. Should you hire an additional worker to run the 8 machines in this manufacturing line?
The Cove is a midsized furniture store. Sales staff are assigned standard shifts (1st shift usually takes place between the hours of 9 a.m. and 5 p.m. 2nd shift is worked between 5 p.m. and 1 a.m. 3rd shift typically takes place between the hours of 12 a.m. and 8 a.m.), and the number of customers arriving per shift averages 40, Poisson distributed. A salesperson can deal with one customer in 5 minutes on average and costs the company $100 per shift in salaries and fringe benefits. Service times closely follow an exponential distribution. The manager is reviewing the number of salespersons to schedule for each shift. The cost of customers waiting before they receive service has been estimated at $2 per minute in terms of lost sales and loss of goodwill.
a. If management wants to minimize the cost of both sales staff and customer wait times, how many salespersons should be working in each shift?
b. What is the cost per shift to the company if they use the number of salespersons you…

The Oryo Cookie IceCream Shop in Dunkirk Square has three competitors. Sincepeople don’t like to wait in long lines for ice cream, thearrival rate to the Oryo Cookie Ice Cream Shop depends onthe number of people in the shop. More specifically, whilej 4 customers are present in the Oryo shop, customersarrive at a rate of (20 5j) customers per hour. If more than4 people are in the Oryo shop, the arrival rate is zero. Foreach customer, revenues less raw material costs are 50¢.Each server is paid $3 per hour. A server can serve anaverage of 10 customers per hour. To maximize expectedprofits (revenues less raw material and labor costs), howmany servers should Oryo hire? Assume that interarrivaland service times are exponential.arrow_forward
- A fleet repair facility has the capacity to repair 800 trucks per month. However, due to scheduled maintenance of their equipment, management feels that they can repair no more than 600 trucks per month. Last month, two of the employees were absent several days each, and only 400 trucks were repaired. Calculate the utilization of the repair shop. Calculate the efficiency of the repair shop. Discuss the utilization and efficiency of this repair facility. What can be done to improve the operations at the facility?arrow_forwardFeVer Beverages is a typical coffee shop that operates at Batangas. Recently, the general manager is facing a challenge about not meeting their target lead time of serving the hot coffee of 15 minutes. The lead time starts from order taking until order serving. The staffing model of the shop has one cashier, one barista and a guard. The number of staff, equipment, and raw materials have been found sufficient. Based on the initial data analysis, the volume of customers has been stable. Because there is a need for the lead time to improve as to retain its customers and to even grow, a problem-solving effort has been started using the Lean Six Sigma DMAIC approach. Using the FEVER Beverages, you should create your own Project Charter and SIPOC Diagram.arrow_forwardTed Glickman, the administrator at D.C. General Hospital emergency room faces the problem of providing treatment for patients who arrive at different rates during the day. There are 4 doctors available to treat patients when needed. If not needed, they can be assigned other responsibilities (such as doing lab tests, reports, X-ray diagnoses) or else rescheduled to work at other hours. It is important to provide quick and responsive treatment, and Ted feels that, on the average, patients should not have to sit in the waiting area for more than 4 minutes before being seen by a doctor. Patients are treated on a first-come, first-served basis and see the first available doctor after waiting in the queue. The arrival pattern for a typical day is as follows: Time Arrival Rate 9 A.M.−3 P.M. 8 patients/hour 3 P.M.−8 P.M. 3 patients/hour 8 P.M.−midnight 13 patients/hour Arrivals follow a Poisson distribution, and treatment times, 12…arrow_forward

A total of 10 million cuft of dirt is needed to construct the dam. A bulldozer is usedto collect dirt for the dam. Then the dirt is moved via dumpersto the dam site. Only one bulldozer is available, and it rentsfor $100 per hour. Bectol can rent, at $40 per hour, as manydumpers as desired. Each dumper can hold 1,000 cu ft ofdirt. It takes an average of 12 minutes for the bulldozer toload a dumper with dirt, and each dumper an average of fiveminutes to deliver the dirt to the dam and return to the bulldozer. Making appropriate assumptions about exponen-tiality, determine how Bectol can minimize the total expected cost of moving the dirt needed to build the dam.arrow_forward
- A crew of mechanics at the Department of Transportation garage make minor repairs to snowplows during the winter. The snowplows break down at an average rate of 4 vehicles per day and breakdowns are distributed according to the Poisson distribution. The mechanic can service an average of 10 vehicles per day with a repair time distribution that approximates a negative exponential distribution. Assume an 8 hour day. What is the system utilization? Group of answer choices 0.60 0.17 0.40 0.67arrow_forwardThe manager of a car wash must decide whether to have one or two wash lines. One line will mean a fixed cost of RM6000 a month, and two lines will mean a fixed cost of RM10500 a month. Each line would be able to process 15 cars an hour. Variable costs will be RM3 per car, and revenue will be RM5.95 per car. The manager projects an average demand of between 14 and 18 cars an hour. Would you recommend one or two lines? The car wash is open 300 hours a month.arrow_forwardHilltop Restaurant is located in Dempsey Hill. The restaurant has a capacity of 35 tables to serve customers. When doing its capacity planning and evaluating operational performance, the restaurant adopts the concept of “customer group” and uses it as unit of measurement to measure the workload in the service process. A customer group is a group of one or more people who arrive, get seated at a table, eat and depart. On average, a customer group takes 70 minutes to eat dinner, and then another 25 minutes to eat dessert. On average, a customer group generates a profit of $100 on dinner, and $30 on dessert. Now assume that Hilltop leases new space to open a “dessert bar” next door, and has opened up the wall between the two units to allow inside access from the restaurant to the dessert bar. The dessert bar can accommodate 15 tables. With this change, a customer group arrives and is seated at a table in Hilltop restaurant as usual. However, when the customer group finishes eating dinner,…arrow_forward
