Sales staff, salaries and commissions                                                 100,000
Total Annual Sales: 60 units
Profit Margin: 15%


SOLUTION:

Variable costs
Raw material and components costs                                                          $2,150,000
Direct labor                                                                                                              950,000
Direct expenses                                                                                                         60,000
Engineering expenses (plant)                                                                               90,000
Engineering staff and salaries (plant)                                                                30,000
                                                                                                                                                    
Total Variable Costs                                                                                   $3,280,000 


Factory Expenses
Utilities for plant                                                                                                $70,000
Taxes and insurance                                                                                            50,000
Plant and equipment depreciation                                                               120,000
Warehouse Expenses                                                                                          60,000
                                                                                                                                                 
Total Factory Expenses                                                                             $300,000


General and Administrative Expenses (G & A)
Plant manager and staff                                                                                $180,000
Office Utilities                                                                                                        10,000
Administrative staff salaries                                                                           120,000
                                                                                                                                                 
Total G & A                                                                                                      $310,000


Manufacturing Cost = Variable costs + Factory Expenses +
                                              General and Administrative Expenses
                                          = $3,280,000 + $300,000 + $310,000
                                          = $3,890,000

Sales, staff, salaries and commissions: $100,000

Total Cost                       = Manufacturing costs + Sales, staff, salaries and commissions 
                                           = $3,990,000
Manufacturing cost for a turbine = $3,990,000


Profit Margin = Profit / Sales 
0.15 = Profit / Sales  -> equation 1
 Sales = Profit + Total Cost
 Sales = (0.15)Sales + $3 990 000  -> equation 2
Interception equation 1 & 2
Sales = $ 4 987 500.00

Sales = Selling Price
   
Total Annual Sales = 60 units
Selling Price for One Turbine    = Selling Price / 60 = $4,987,500.00 / 60

Selling Price                                           = $83,125.00 per unit

ASSIGNMENT 17.3 BREAK-EVEN POINT



QUESTION


The type of tooling to make for a manufacturing process depends on the expected total quantity of parts. Tooling made from standard components and less wear-resistant materials (soft tooling) can be made more quickly and cheaply than conventional tooling made from hardened steel (hard tooling). Use the concept of break-even point to determine the production quantity for which soft tooling can be justified. 
The following cost data applies:

                                                Soft tooling                                     Hard tooling
Tool           Tooling cost                     CS $600                                                CH $7500
Setu         Setup cost                         SS $100                                                  SH $60
Unit         Unit Part cost                  CPS $3.40                                             CPH $0.80

 ANSWER

 


The break-even point is the sales or production volume at which sales and costs balance.
CH + (QBEP/b) S+ CPH QBEP = CS + (QBEP/b)  SS+ CPS QBEP
Break-even point
QBEP = C- C/ [(S- SH}/b) + (CPS - CPH)]
         = 7500 – 600/ [((100 – 60)/500) + (3.4 – 0.8)]
         = 2574.63
         = 2575 units

Problem 17.2
QUESTION:

Many consumers item today are designed in the United State and manufactured over-seas where labor cost is much lower. A middle range athletic shoe from a name brand manufacturer sells for $70 in the U.S. The shoe company buys the shoe from an off-shore supplier for $20 and sells to the retailer for $36. The profit margin for each unit in the chain is: supplier-9%, shoe company-17%, retailer-13%. Estimate major categories of cost breakdown for each unit of chain. Do this as a team problem and compare the results for the entire class.

ASSIGNMENT 17.1

QUESTION:

In an environmental upgrade of a minimill making steel bar, it is found that a purchase must be made for a large cyclone dust collector. It is the time of the year for capital budget submissions, so there is no time for quotations from suppliers. The last unit of that type was purchased in 1985 for $35,000. It had a 100ft3/min capacity. The new installation in 2012 will require 1000ft3/min capacity. The cost escalation for this kind of equipment has been about 5 percent per year. For budget purposes, estimate what it will cost to purchase the dust collector.


Answer:
To answer this question, equation below is provided:


C1 = C0 (L1/L0)x    (Cost-Size Relationship ~page799)
  • C0= $35,000    
  • L0= 100ft3/min
  • L1= 1000ft3/min         
  • C1= ?
Based on Table 17.4 in the text book, x for dust collector= 0.61. Because of economies of scale, the new unit has 10 times the capacity as the unit purchased in 1985 will not cost 10 times moreHowever, the purchase cost will have increased because of inflation in the 27 years since it was purchased in 1985. Assuming cost inflation in of 5% per year, the original cost of $35,000 is now equivalent to:
P= F(1+i)n
P=35000(1+0.05)27 
 = 35000(2.92526) 
 = $130 671.00

Thus, the cost estimation can be calculated as:
CC0 (L1/L0)
       =130 671.00(1000/100)0.61 
     = $ 532 327.00

ASSIGNMENT 13.1 SHAPE-REPLICATION AND SHAPE-GENERATIVE


ASSIGNMENT 13.1  


QUESTION :

Classify the following manufacturing processes as to whether they are shape-replication or shape-generative:
(a)Honing the bore of a cylinder,
(b)Powder metallurgy gear,
(c)Rough turning a cast roll,
(d)Extrusion of vinyl house siding.


ANSWER:

 Shape replication is an example of process under mass conserving which the part replicates the information stored in the tooling by being forced to assume the shape of the surface of the tool cavity. The examples of shape-replication process can be define by the process of casting, injection molding, and closed-die forging. In addition, during mass reducing processes or shape-generation processes, the starting material is greater than the mass of the final part. This is because the part shape is produced by the relative motion between the tool and the workpiece. The examples manufacturing processes that undergo through this process is milling and drilling.

The manufacturing processes are classified as follow: 
(a)    Honing the bore of a cylinder      
     *Shape-generation
     
(b)   Powder metallurgy gear               
     *Shape- replication
      
(c)    Rough turning a cast roll               
     *Shape-generation
     
(d)   Extrusion of vinyl house siding 
     *Shape-replication
