Concept explainers
Ozark Industries manufactures and sells three products, which are manufactured in a factory with four departments. Both labor and machine time are applied to the products as they pass through each department. The machines and labor skills required in each department are so specialized that neither machines nor labor can be switched from one department to another.
Ozark Industries’ management is planning its production schedule for the next few months. The planning is complicated, because there are labor shortages in the community and some machines will be down several months for repairs.
Management has assembled the following information regarding available machine and labor time by department and the machine hours and direct-labor hours required per unit of product. These data should be valid for the next six months.
Inventory levels are satisfactory and need not be increased or decreased during the next six months. Unit price and cost data that will be valid for the next six months are as follows:
Required:
- 1. Calculate the monthly requirement for machine hours and direct-labor hours for the production of products M07, T28, and B19 to determine whether the monthly sales demand for the three products can be met by the factory.
- 2. What monthly production schedule should Ozark Industries select in order to maximize its dollar profits? Explain how you selected this production schedule, and present a schedule of the contribution to profit that would be generated by your production schedule.
- 3. Identify the alternatives Ozark Industries might consider so it can supply its customers with all the product they demand.
1.
Calculate the monthly requirement for machine hours and direct labor hours for the production of products M07 and B19 to ascertain whether the monthly sales demand for the three products are met by the factory.
Explanation of Solution
Manufacturing overheads: Manufacturing overheads refers to the indirect factory- related cost that has occurred while manufacturing a product. Some of the examples of manufacturing overheads are indirect labor, indirect materials, factory building and indirect factory supplies.
The monthly requirement for machine hours is calculated as follows:

Table (2)
Due to the labor shortage in Department 3, the monthly sales demand cannot be met for all three products
Note: Monthly requirement for direct labor is computed by multiplying the monthly unit sale of each product with the direct labor required for each department.
2.
Identify the monthly production schedule that Industry O must select in order to maximize its dollar profits, explain the manner in which the production schedule is selected, and present a schedule of the contribution to profit that is generated by the production schedule.
Explanation of Solution
Contribution Margin: The process or theory which is used to judge the benefit given by each unit of the goods produced is called as contribution margin.
“The aim is to increase contribution margin. Fixed costs are irrelevant. Direct-labor hours (DLH) are the scarce resource in Department 3. Industry must initially produce the product that maximizes contribution margin per unit of the scarce resource (DLH). In this situation, two products, M07 and B19, need direct-labor hours in Department 3”.
Calculate the contribution margin:
M07 | T28 | B19 | |
Sales price (a) | $196 | $123 | $167 |
Variable costs | |||
Direct material | $7 | $13 | $17 |
Direct labor | $66 | $38 | $51 |
Variable overhead | $27 | $20 | $25 |
Variable selling | $3 | $2 | $4 |
Total variable costs (b) | $103 | $ 73 | $ 97 |
Contribution margin | $ 93 | $ 50 | $ 70 |
Note: Direct labor is computed by adding the direct labor of Department 1, Department 2, Department 3, and Department 4.

MANAGERIAL ACCOUNTING-ACCESS
- Ingles Corporation is a manufacturer of tables sold to schools, restaurants, hotels, and other institutions. The table tops are manufactured by Ingles, but the table legs are purchased from an outside supplier. The Assembly Department takes a manufactured table top and attaches the four purchased table legs. It takes 16 minutes of labor to assemble a table. The company follows a policy of producing enough tables to ensure that 40 percent of next months sales are in the finished goods inventory. Ingles also purchases sufficient materials to ensure that materials inventory is 60 percent of the following months scheduled production. Ingless sales budget in units for the next quarter is as follows: Ingless ending inventories in units for July 31 are as follows: Required: 1. Calculate the number of tables to be produced during August. 2. Disregarding your response to Requirement 1, assume the required production units for August and September are 2,100 and 1,900, respectively, and the July 31 materials inventory is 4,000 units. Compute the number of table legs to be purchased in August. 3. Assume that Ingles Corporation will produce 2,340 units in September. How many employees will be required for the Assembly Department in September? (Fractional employees are acceptable since employees can be hired on a part-time basis.

Calculate the total time it takes to produce a batch of 20 units using Andersons traditional departmental structure. 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. What if the processing times of molding, welding, and assembly are all reduced to six minutes each? What is the production rate now, and how long will it take to produce a batch of 20 units?arrow_forwardBig Mikes, a large hardware store, has gathered data on its overhead activities and associated costs for the past 10 months. Nizam Sanjay, a member of the controllers department, believes that overhead activities and costs should be classified into groups that have the same driver. He has decided that unloading incoming goods, counting goods, and inspecting goods can be grouped together as a more general receiving activity, since these three activities are all driven by the number of receiving orders. The 10 months of data shown below have been gathered for the receiving activity. Required: 1. Prepare a scattergraph, plotting the receiving costs against the number of purchase orders. Use the vertical axis for costs and the horizontal axis for orders. 2. Select two points that make the best fit, and compute a cost formula for receiving costs. 3. Using the high-low method, prepare a cost formula for the receiving activity. 4. Using the method of least squares, prepare a cost formula for the receiving activity.

For Mixing, sufficient materials are released to produce 4,000 packages of product per day. Encapsulating has a buffer inventory of 8,000 units (work in process from Mixing). Packaging produces 4,000 units per day. Which of the three processes sets the production rate of 4,000 units per day? a. The Mixing Department b. The Encapsulating Department c. The Packaging Department d. Cannot be determinedarrow_forwardVargas, Inc., produces industrial machinery. Vargas has a machining department and a group of direct laborers called machinists. Each machinist is paid 25,000 and can machine up to 500 units per year. Vargas also hires supervisors to develop machine specification plans and to oversee production within the machining department. Given the planning and supervisory work, a supervisor can oversee three machinists, at most. Vargass accounting and production history reveal the following relationships between units produced and the costs of direct labor and supervision (measured on an annual basis): Required: 1. Prepare two graphs: one that illustrates the relationship between direct labor cost and units produced, and one that illustrates the relationship between the cost of supervision and units produced. Let cost be the vertical axis and units produced the horizontal axis. 2. How would you classify each cost? Why? 3. Suppose that the normal range of activity is between 2,400 and 2,450 units and that the exact number of machinists is currently hired to support this level of activity. Further suppose that production for the next year is expected to increase by an additional 400 units. How much will the cost of direct labor increase (and how will this increase be realized)? Cost of supervision?arrow_forward
- 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.

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?arrow_forward
- 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.arrow_forwardThe Calhoun Textile Mill is in the process of deciding on a production schedule. It wishes to know how to weave the various fabrics it will produce during the coming quarter. The sales department has continued orders for each of the 15 fabrics produced by Calhoun. These demands are given in the following table. Also given in this table is the variable cost for each fabric. The mill operates continuously during the quarter: 13 weeks, 7 days a week, and 24 hours a day. There are two types of looms: dobbie and regular. Dobbie looms can be used to make all fabrics and are the only looms that can weave certain fabrics, such as plaids. The rate of production for each fabric on each type of loom is also given in the table. Note that if the production rate is zero, the fabric cannot be woven on that type of loom. Also, if a fabric can be woven on each type of loom, then the production rates are equal. Calhoun has 90 regular looms and 15 dobbie looms. For this problem, assume that the time requirement to change over a loom from one fabric to another is negligible. Management would like to know how to allocate the looms to the fabrics and which fabrics to buy on the market so as to minimize the cost of meeting demand.arrow_forwardMabbut 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.
