-ith tight (d) Rachel knows that overtime labor does not come without an ex- a mod- tra cost. What is the maximum amount she should be willing to del, the pay for all overtime labor beyond the cost of this labor at reg- er seats, ular time rates? Express your answer as lump sum. 1 (e) Rachel explores the option of using both the targeted advertis- upper- ing campaign and the overtime labor-hours. The advertising gener- campaign raises the demand for the Classy Cruiser by 20 per- cent, and the overtime labor increases the plant's labor-hour ca- pacity by 25 percent. How many Family Thrillseekers and how - plant, many Classy Cruisers should be assembled using the advertis- ne next ing campaign and overtime labor-hours if the profit from each Family Classy Cruiser sold continues to be 50 percent more than for able in each Family Thrillseeker sold? knows (f) Knowing that the advertising campaign costs $500,000 and the rs dur maximum usage of overtime labor-hours costs $1,600,000 be- ours to yond regular time rates, is the solution found in part (e) a wise urs to decision compared to the solution found in part (a)? (g) Automobile Alliance has determined that dealerships are actu- ally heavily discounting the price of the Family Thrillseekers parts to move them off the lot. Because of a profit-sharing agreement at the with its dealers, the company is therefore not making a profit nd the of $3,600 on the Family Thrillseeker but is instead making a profit of $2,800. Determine the number of Family Thrillseek- ers and the number of Classy Cruisers that should be assem- nows bled given this new discounted price. 0,000 (h) The company has discovered quality problems with the Fam- door ily Thrillseeker by randomly testing Thrillseekers at the end of the assembly line. Inspectors have discovered that in over will 60 percent of the cases, two of the four doors on a Thrillseeker do not seal properly. Because the percentage of defective aiser Thrillseekers determined by the random testing is so high, the floor supervisor has decided to perform quality control tests on every Thrillseeker at the end of the line. Because of the thly added tests, the time it takes to assemble one Family the Thrillseeker has increased from 6 to 7.5 hours. Determine the ars. number of units of each model that should be assembled given ker the new assembly time for the Family Thrillseeker. (i) The board of directors of Automobile Alliance wishes to cap- ter- ture a larger share of the luxury sedan market and therefore at the full demand for Classy Cruisers. They tires, from that next CASE 3.1 Auto Assembly Automobile Alliance, a large automobile manufacturing company, organizes the vehicles it manufactures into three families: a family of trucks, a family of small cars, and a family of midsized and luxury cars. One plant outside Detroit, MI, assembles two models from the family of mid- sized and luxury cars. The first model, the Family Thrillseeker, is a four-door sedan with vinyl seats, plastic in terior, standard features, and excellent gas mileage. It is CASES marketed as a smart buy for middle-class families with tight budgets, and each Family Thrillseeker sold generates a mod- est profit of $3,600 for the company. The second model, the Classy Cruiser, is a two-door luxury sedan with leather seats, wooden interior, custom features, and navigational capa- bilities. It is marketed as a privilege of affluence for upper- middle-class families, and each Classy Cruiser sold gener- ates a healthy profit of $5,400 for the company. Rachel Rosencrantz, the manager of the assembly plant, is currently deciding the production schedule for the next month. Specifically, she must decide how many Family Thrillseekers and how many Classy Cruisers to assemble in the plant to maximize profit for the company. She knows that the plant possesses a capacity of 48,000 labor-hours dur- ing the month. She also knows that it takes 6 labor-hours to assemble one Family Thrillseeker and 10.5 labor-hours to assemble one Classy Cruiser. Because the plant is simply an assembly plant, the parts required to assemble the two models are not produced at the plant. They are instead shipped from other plants around the Michigan area to the assembly plant. For example, tires, steering wheels, windows, seats, and doors all arrive from various supplier plants. For the next month, Rachel knows that she will be able to obtain only 20,000 doors (10,000 left-hand doors and 10,000 right-hand doors) from the door supplier. A recent labor strike forced the shutdown of that particular supplier plant for several days, and that plant will not be able to meet its production schedule for the next month. Both the Family Thrillseeker and the Classy Cruiser use the same door part. In addition, a recent company forecast of the monthly demands for different automobile models suggests that the demand for the Classy Cruiser is limited to 3,500 cars. There is no limit on the demand for the Family Thrillseeker within the capacity limits of the assembly plant. (a) Formulate and solve a linear programming problem to deter- mine the number of Family Thrillseekers and the number of Classy Cruisers that should be assembled. Before she makes her final production decisions, Rachel plans to explore the following questions independently ex- cept where otherwise indicated. LANCI (b) The marketing department knows that it can pursue a targeted $500,000 advertising campaign that will raise the demand for the Classy Cruiser next month by 20 percent. Should the cam- paign be undertaken? (c) Rachel knows that she can increase next month's plant capacity by using overtime labor. She can increase the plant's labor-hour capacity by 25 percent. With the new assembly plant capacity, how many Family Thrillseekers and how many Classy Cruisers should be assembled? (d) Rachel knows that overtime labor does not come without an ex- tra cost. What is the maximum amount she should be willing to pay for all overtime labor beyond the cost of this labor at reg- ular time rates? Express your answer as m iumo sam
