Vollmer Manufacturing makes three components for sale to refrigeration companies. The components are processed on two machines: a shaper and a grinder. The times (in minutes) required on each machine are as follows: The shaper is available for 120 hours, and the grinder for 110 hours. No more than 200 units of component 3 can be sold, but up to 1,000 units of each of the other components can be sold. In fact, the company already has orders for 600 units of component 1 that must be satisfied. The profit contributions for components 1, 2, and 3 are 8, 6, and 9, respectively. a. Formulate and solve for the recommended production quantities. b. What are the objective coefficient ranges for the three components? Interpret these ranges for company management. c. What are the right-hand-side ranges? Interpret these ranges for company management. d. If more time could be made available on the grinder, how much would it be worth? e. If more units of component 3 can be sold by reducing the sales price by 4, should the company reduce the price?
Elliott, Inc., has four salaried clerks to process purchase orders. Each clerk is paid a salary of 25,750 and is capable of processing as many as 6,500 purchase orders per year. Each clerk uses a PC and laser printer in processing orders. Time available on each PC system is sufficient to process 6,500 orders per year. The cost of each PC system is 1,100 per year. In addition to the salaries, Elliott spends 27,560 for forms, postage, and other supplies (assuming 26,000 purchase orders are processed). During the year, 25,350 orders were processed. Required: 1. Classify the resources associated with purchasing as (1) flexible or (2) committed. 2. Compute the total activity availability, and break this into activity usage and unused activity. 3. Calculate the total cost of resources supplied (activity cost), and break this into the cost of activity used and the cost of unused activity. 4. (a) Suppose that a large special order will cause an additional 500 purchase orders. What purchasing costs are relevant? By how much will purchasing costs increase if the order is accepted? (b) Suppose that the special order causes 700 additional purchase orders. How will your answer to (a) change?
Computador has a manufacturing plant in Des Moines that has the theoretical capability to produce 243,000 laptops per quarter but currently produces 91,125 units. The conversion cost per quarter is 7,290,000. There are 60,750 production hours available within the plant per quarter. In addition to the processing minutes per unit used, the production of the laptops uses 10 minutes of move time, 20 minutes of wait time, and 5 minutes of rework time. (All work is done by cell workers.) Required: 1. Compute the theoretical and actual velocities (per hour) and the theoretical and actual cycle times (minutes per unit produced). 2. Compute the ideal and actual amounts of conversion cost assigned per laptop. 3. Calculate MCE. How does MCE relate to the conversion cost per laptop?
Taylor Company produces two industrial cleansers that use the same liquid chemical input: Pocolimpio and Maslimpio. Pocolimpio uses two quarts of the chemical for every unit produced, and Maslimpio uses five quarts. Currently, Taylor has 6,000 quarts of the material in inventory. All of the material is imported. For the coming year, Taylor plans to import 6,000 quarts to produce 1,000 units of Pocolimpio and 2,000 units of Maslimpio. The detail of each products unit contribution margin is as follows: Taylor Company has received word that the source of the material has been shut down by embargo. Consequently, the company will not be able to import the 6,000 quarts it planned to use in the coming years production. There is no other source of the material. Required: 1. Compute the total contribution margin that the company would earn if it could import the 6,000 quarts of the material. 2. Determine the optimal usage of the companys inventory of 6,000 quarts of the material. Compute the total contribution margin for the product mix that you recommend. 3. Assume that Pocolimpio uses three direct labor hours for every unit produced and that Maslimpio uses two hours. A total of 6,000 direct labor hours is available for the coming year. a. Formulate the linear programming problem faced by Taylor Company. To do so, you must derive mathematical expressions for the objective function and for the materials and labor constraints. b. Solve the linear programming problem using the graphical approach. c. Compute the total contribution margin produced by the optimal mix.
Rolertyme Company manufactures roller skates. With the exception of the rollers, all parts of the skates are produced internally. Neeta Booth, president of Rolertyme, has decided to make the rollers instead of buying them from external suppliers. The company needs 100,000 sets per year (currently it pays 1.90 per set of rollers). The rollers can be produced using an available area within the plant. However, equipment for production of the rollers would need to be leased (30,000 per year lease payment). Additionally, it would cost 0.50 per machine hour for power, oil, and other operating expenses. The equipment will provide 60,000 machine hours per year. Direct material costs will average 0.75 per set, and direct labor will average 0.25 per set. Since only one type of roller would be produced, no additional demands would be made on the setup activity. Other overhead activities (besides machining and setups), however, would be affected. The companys cost management system provides the following information about the current status of the overhead activities that would be affected. (The supply and demand figures do not include the effect of roller production on these activities.) The lumpy quantity indicates how much capacity must be purchased should any expansion of activity supply be needed. The purchase price is the cost of acquiring the capacity represented by the lumpy quantity. This price also represents the cost of current spending on existing activity supply (for each block of activity). Production of rollers would place the following demands on the overhead activities: Producing the rollers also means that the purchase of outside rollers will cease. Thus, purchase orders associated with the outside acquisition of rollers will drop by 5,000. Similarly, the moves for the handling of incoming orders will decrease by 200. The company has not inspected the rollers purchased from outside suppliers. Required: 1. Classify all resources associated with the production of rollers as flexible resources and committed resources. Label each committed resource as a short- or long-term commitment. How should we describe the cost behavior of these short- and long-term resource commitments? Explain. 2. Calculate the total annual resource spending (for all activities except for setups) that the company will incur after production of the rollers begins. Break this cost into fixed and variable activity costs. In calculating these figures, assume that the company will spend no more than necessary. What is the effect on resource spending caused by production of the rollers? 3. Refer to Requirement 2. For each activity, break down the cost of activity supplied into the cost of activity output and the cost of unused activity.
Jansen Crafters has the capacity to produce 50,000 oak shelves per year and is currently selling 44,000 shelves for $32 each. Cutrate Furniture approached Jansen about buying 1,200 shelves for bookcases it is building and is willing to pay $26 for each shelf. No packaging will be required for the bulk order. Jansen usually packages shelves for Home Depot at a price of $1.50 per shell. The $1.50 per-shelf cost is included in the unit variable cost of $27, with annual fixed costs of $320.000. However, the $130 packaging cost will not apply in this case. The fixed costs will be unaffected by the special order and the company has the capacity to accept the order. Based on this information, what would be the profit if Jansen accepts the special order? A. Profits will decrease by $1,200. B. Profits will increase by $31,200. C. Profits will increase by $600. D. Profits will increase by $7,200.
Ottis, Inc., uses 640,000 plastic housing units each year in its production of paper shredders. The cost of placing an order is 30. The cost of holding one unit of inventory for one year is 15.00. Currently, Ottis places 160 orders of 4,000 plastic housing units per year. Required: 1. Compute the economic order quantity. 2. Compute the ordering, carrying, and total costs for the EOQ. 3. How much money does using the EOQ policy save the company over the policy of purchasing 4,000 plastic housing units per order?
Markson and Sons leases a copy machine with terms that include a fixed fee each month plus acharge for each copy made. Markson made 9,000 copies and paid a total of $480 in January. In April, they paid $320 for 5,000 copies. What is the variable cost per copy if Markson uses the high-low method to analyze costs?
Remarkable Enterprises requires four units of part A for every unit of Al that it produces. Currently, part A is made by Remarkable, with these per-unit costs in a month when 4,000 units were produced: Variable manufacturing overhead is applied at $1.60 per unit. The other $0.50 of overhead consists of allocated fixed costs. Remarkable will need 8,000 units of part A for the next years production. Altoona Corporation has offered to supply 8,000 units of part A at a price of $8.00 per unit. If Remarkable accepts the offer, all of the variable costs and $2,000 of the fixed costs will be avoided. Should Remarkable accept the offer from Altoona Corporation?
Gent Designs requires three units of part A for every unit of Al that it produces. Currently, part A is made by Gent, with these per-unit costs in a month when 4.000 units were produced: Variable manufacturing overhead is applied at $1.00 per unit. The other $0.30 of overhead consists of allocated fixed costs. Gent will need 6,000 units of part A for the next years production. Cory Corporation has offered to supply 6,000 units of part A at a price of $7.00 per unit. It Gent accepts the offer, all of the variable costs and $1,200 of the fixed costs will be avoided. Should Gent Designs accept the offer from Cory Corporation?
Power Corp. makes 2 products: blades for table saws and blades for handsaws. Each product passes through the sharpening machine area, which is the chief constraint during production. Handsaw blades take 15 minutes on the sharpening machine and have a contribution margin per blade of $15. Table saw blades take 20 minutes on the sharpening machine and have a contribution margin per blade of $35. If it is assumed that Power Corp. has 5,000 hours available on the sharpening machine to service a minimum demand for each product of 4,000 units, how many of each product should be made?
Paladin Company manufactures plain-paper fax machines in a small factory in Minnesota. Sales have increased by 50 percent in each of the past three years, as Paladin has expanded its market from the United States to Canada and Mexico. As a result, the Minnesota factory is at capacity. Beryl Adams, president of Paladin, has examined the situation and developed the following alternatives. 1. Add a permanent second shift at the plant. However, the semiskilled workers who assemble the fax machines are in short supply, and the wage rate of 15 per hour would probably have to be increased across the board to 18 per hour in order to attract sufficient workers from out of town. The total wage increase (including fringe benefits) would amount to 125,000. The heavier use of plant facilities would lead to increased plant maintenance and small tool cost. 2. Open a new plant and locate it in Mexico. Wages (including fringe benefits) would average 3.50 per hour. Investment in plant and equipment would amount to 300,000. 3. Open a new plant and locate it in a foreign trade zone, possibly in Dallas. Wages would be somewhat lower than in Minnesota, but higher than in Mexico. The advantages of postponing tariff payments on parts imported from Asia could amount to 50,000 per year. Required: Advise Beryl of the advantages and disadvantages of each of her alternatives.
