- Seas Beginning sells clothing by mail order. An important question is when to strike a customer from the companys mailing list. At present, the company strikes a customer from its mailing list if a customer fails to order from six consecutive catalogs. The company wants to know whether striking a customer from its list after a customer fails to order from four consecutive catalogs results in a higher profit per customer. The following data are available: If a customer placed an order the last time she received a catalog, then there is a 20% chance she will order from the next catalog. If a customer last placed an order one catalog ago, there is a 16% chance she will order from the next catalog she receives. If a customer last placed an order two catalogs ago, there is a 12% chance she will order from the next catalog she receives. If a customer last placed an order three catalogs ago, there is an 8% chance she will order from the next catalog she receives. If a customer last placed an order four catalogs ago, there is a 4% chance she will order from the next catalog she receives. If a customer last placed an order five catalogs ago, there is a 2% chance she will order from the next catalog she receives. It costs 2 to send a catalog, and the average profit per order is 30. Assume a customer has just placed an order. To maximize expected profit per customer, would Seas Beginning make more money canceling such a customer after six nonorders or four nonorders?arrow_forwardA UCLA student saved $100,000 for the down payment on a $1,000,000 one-bedroom, two-bathroom home in Encino, California.

Ruggle, Professor, Department of Accounting, Mankato State University Arnie Armstrong has been with Pierce Auto Parts Manufacturing Company for 23 years. Recently, he was appointed Director of Manufacturing Computer Services. In just six weeks in this new position, [he] has moved to reduce the amount of information provided to manufacturing department managers by 60 percent. He argues that excess data is distracting, unused, and expensive to provide. Willy McClean has been department manager for 12 years. During a coffee break with some of his department production supervisors, Willy is quite vocal about the change. “Who’s this guy Armstrong to tell us what data we need? He needs to be out here for a few weeks to find out what it’s like. Keep it quiet, but I’ve got a contact in Computer Services who’ll get me all the data analyses I want for just a $20 bill each month. It’s a good deal, and Armstrong will never know.

- Emily works for a small software company and oversees software quality assurance. The company recently developed an inventory control system for a national clothing manufacturer. The system gathers sales information on an hourly basis from clothing retailers nationwide. This information is then used by all departments (including the accounting, shipping, and ordering departments) to control the functions of the clothing manufacturer. Emily suspects that the inventory functions of the system are not sufficiently tested, although they have passed all their contracted (legal) tests. However, she is pressured by her employers to sign off on the software. Whilst she is only required to perform tests which have been agreed to in the original contract, her considerable experience in software testing has led her to be concerned over the quality of the system. Her employers say that they will go out of business if they do not deliver the software on time. Emily knows that if any section of…arrow_forwardLynn Jennings is the IT manager at Lazy Eddie, a chain that specializes in beanbag chairs and recliners. She asked Jan Lauten, a senior systems analyst, to review the large number of printed reports that are distributed to Lazy Eddie’s 35 store managers. “Jan, I just can’t believe that our people really read all of those reports,” Lynn said. “We constantly add new reports, and we never seem to eliminate the old ones. Sometimes I think all we’re doing is keeping the paper companies in business!” Jan replied, “I agree, but what can we do? The managers say they want the reports, but I always see them stacked on top of file cabinets. I’ve never seen anyone read a report.” “I have an idea,” Lynn said. “I want you to come up with a procedure that requires users to review and justify their information needs to see if they really use the reports we send them. You could design a form that asks if the information still is required, and why. Try to get users to decide if a report is worth the…arrow_forwardThe Reeves twins are in the yard maintenance business. They want to start doing snow removal during the winter season because they practically don't have any yards to maintain. The twins are trying to determine how much equipment they need to purchase. The twins plan to do most of the work themselves and then hire some part-time workers on an individual job basis to help out. The twins gathered some data on past weather. Based on the information, they predict that there will be six big snowstorms in the coming winter. Most of their clients want the snow removed no more than two days after the snow stops falling. If the twins work for 10 hours a day, they can remove the snow from the driveway of a home in about 1 hour. However, for commercial parking lots and public sidewalks, it will take 4 hours. The variable cost per job is $12 for home driveways and $47 for commercial parking lots. The twins estimated that they will have no more than 40 homeowners and 25 businesses who would like…arrow_forward
- A retail store sold in the month of April 5,000 products that produced $45,000 in sales. In the month of May the company sold 6,000 products. The store workforce consists of four full-time workers who work 40-hour week. In April the store also had seven part-time workers at 10 hours per week, and in May the store had nine part-timers at 15 hours per week (assume four weeks in each month). Using sales dollars as the measure of output (assume the price of the product was the same for both months), what is the percentage change in labor productivity from April to May?

The profit per night for each type of room and rental class is as follows: Rental Class Super Saver Deluxe Business Type I (Mountain View) $30 $35 Room Type II (Street View) $15 $25 $35 Round Tree's management makes a forecast of the demand by rental class for each night in the future. A linear programming model developed to maximize profit is used to determine how many reservations to accept for each rental class. The demand forecast for a particular night is 110 rentals in the Super Saver class, 55 in the Deluxe class, and 40 in the Business class. Since these are the forecasted demands, Round Tree will take no more than these amounts of each reservation for each rental class. Round Tree has a limited number of each type of room.
