Man OFort Inc. produces two different styles of door handles, standard and curved. The door handles go through a joint production molding process costing 29,000 per batch and producing 2,000 standard door handles and 1,000 curved door handles at the split-off point. Both door handles undergo additional production processes after the split-off point, but could be sold at that point: the standard style for 4 per door handle and the curved style for 2 per door handle. Determine the amount of joint production costs allocated to each style of door handle using the market value at split-off method.
Mabbut Company has the following departmental manufacturing layout for one of its plants: A consulting firm recommended a value stream with the following manufacturing cell: Required: 1. Calculate the total time it takes to produce a batch of 10 units using the traditional departmental manufacturing layout. 2. Using cellular manufacturing, how much time is saved producing the same batch of 10 units? Assuming the cell operates continuously, what is the production rate? Which process controls this production rate? 3. Assume the processing time of Welding is reduced to 6 minutes, while the times of the other processes stay the same. What is the production rate now, and how long will it take to produce a batch of 10 units if the cell is in a continuous production mode?
Carsen Company produces handcrafted pottery that uses two inputs: materials and labor. During the past quarter, 24,000 units were produced, requiring 96,000 pounds of materials and 48,000 hours of labor. An engineering efficiency study commissioned by the local university revealed that Carsen can produce the same 24,000 units of output using either of the following two combinations of inputs: The cost of materials is 8 per pound; the cost of labor is 12 per hour. Required: 1. Compute the output-input ratio for each input of Combination F1. Does this represent a productivity improvement over the current use of inputs? What is the total dollar value of the improvement? Classify this as a technical or an allocative efficiency improvement. 2. Compute the output-input ratio for each input of Combination F2. Does this represent a productivity improvement over the current use of inputs? Now, compare these ratios to those of Combination F1. What has happened? 3. Compute the cost of producing 24,000 units of output using Combination F1. Compare this cost to the cost using Combination F2. Does moving from Combination F1 to Combination F2 represent a productivity improvement? Explain.
Gumbrecht Company has the following departmental manufacturing layout for one of its plants: A consulting firm has recommended a value stream with the following manufacturing cell: Required: 1. Calculate the total time it takes to produce a batch of 20 units using the traditional departmental manufacturing layout. 2. Using cellular manufacturing, how much time is saved producing the same batch of 20 units? Assuming the cell operates continuously, what is the production rate? Which process controls this production rate? 3. Assume the processing time of Casting is reduced to 9 minutes, while the times of the other processes stay the same. What is the production rate now, and how long will it take to produce a batch of 20 units if the cell is in a continuous production mode?
Hatch Manufacturing produces multiple machine parts. The theoretical cycle time for one of its products is 65 minutes per unit. The budgeted conversion costs for the manufacturing cell dedicated to the product are 12,960,000 per year. The total labor minutes available are 1,440,000. During the year, the cell was able to produce 0.6 units of the product per hour. Suppose also that production incentives exist to minimize unit product costs. Required: 1. Compute the theoretical conversion cost per unit. 2. Compute the applied conversion cost per minute (the amount of conversion cost actually assigned to the product). 3. Discuss how this approach to assigning conversion cost can improve delivery time performance. Explain how conversion cost acts as a performance driver for on-time deliveries.
Eagle Brand Inc. produces two products as follows: Eagle Brand has 1,000 lbs. of raw materials that can be used to produce Products X and Y. Which of the following alternatives should Eagle Brand accept to maximize the contribution margin? a. 100 units of Product Y. b. 250 units of Product X. c. 200 units of Product X and 20 units of Product Y. d. 200 units of Product X and 50 units of Product Y.
Box Springs, Inc., makes two sizes of box springs: twin and double. The direct material for the twin is $25 per unit and $40 s used in direct labor, while the direct material for the double is $40 per unit, and the labor cost is $50 per unit. Box Springs estimates it will make 5,000 twins and 9,000 doubles in the next year. It estimates the overhead for each cost pool and cost driver activities as follows: How much does each unit cost to manufacture?
Lander Parts, Inc., produces various automobile parts. In one plant, Lander has a manufacturing cell with the theoretical capability to produce 450,000 fuel pumps per quarter. The conversion cost per quarter is 9,000,000. There are 150,000 production hours available within the cell per quarter. Required: 1. Compute the theoretical velocity (per hour) and the theoretical cycle time (minutes per unit produced). 2. Compute the ideal amount of conversion cost that will be assigned per subassembly. 3. Suppose the actual time required to produce a fuel pump is 40 minutes. Compute the amount of conversion cost actually assigned to each unit produced. What happens to product cost if the time to produce a unit is decreased to 25 minutes? How can a firm encourage managers to reduce cycle time? Finally, discuss how this approach to assigning conversion cost can improve delivery time. 4. Assuming the actual time to produce one fuel pump is 40 minutes, calculate MCE. How much non-value-added time is being used? How much is it costing per unit? 5. Cycle time, velocity, MCE, conversion cost per unit (theoretical conversion rate actual conversion time), and non-value-added costs are all measures of performance for the cell process. Discuss the incentives provided by these measures.
Use the information provided to create a standard cost card for production of one glove box switch. To make one switch it takes 16 feet of plastic-coated copper wire and 0.5 pounds of plastic material. The plastic material can usually be purchased for $20.00 per pound, and the wire costs $2.50 per foot. The labor necessary to assemble a switch consists of two types. The first type of labor is assembly, which takes 3.5 hours. These workers are paid $27.00 per hour. The second type of labor is finishing, which takes 2 hours. These workers are paid $29.00 per hour. Overhead is applied using labor hours. The variable overhead rate is $14.90 per labor hour. The fixed overhead rate is $15.60 per hour.
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?
Patz Company produces two types of machine parts: Part A and Part B, with unit contribution margins of 300 and 600, respectively.

Required: 1. Express the objective of maximizing the total contribution margin subject to the assembly-hour constraint. 2. Identify the optimal amount that should be produced of each machine part and the total contribution margin associated with this mix. 3. What if market conditions are such that Patz can sell at most 75 units of Part A and 60 units of Part B? Express the objective function with its associated constraints for this case and identify the optimal mix and its associated total contribution margin.
