EBK PRINCIPLES OF OPERATIONS MANAGEMENT, Chapter 5, Problem 18P , additional homework tip  2

Calculation of total cost:

Low technology:

  • Probability 0.3

Totalcost=Fixedcost+Variablecost=$45,000+(200,000×$0.55)=$155,000

With a probability of 0.3, the variable cost is calculated by multiplying the total market forecast of 200,000 with the variable cost $0.55. The product is added with the fixed cost, which is $45,000. The resultant total cost is $155,000.

  • Probability 0.4

Totalcost=Fixedcost+Variablecost=$45,000+(200,000×$0.50)=$145,000

With a probability of 0.4, the variable cost is calculated by multiplying the total market forecast of 200,000 with the variable cost $0.50. The product is added with the fixed cost, which is $45,000. The resultant total cost is $145,000.

  • Probability 0.3

Totalcost=Fixedcost+Variablecost=$45,000+(200,000×$0.45)=$135,000

With a probability of 0.3, the variable cost is calculated by multiplying the total market forecast of 200,000 with the variable cost $0.45. The product is added with the fixed cost, which is $45,000. The resultant total cost is $135,000.

Sub-contract:

  • Probability 0.7

Totalcost=Fixedcost+Variablecost=$65,000+(200,000×$0.45)=$155,000

With a probability of 0.7, the variable cost is calculated by multiplying the total market forecast of 200,000 with the variable cost $0.45. The product is added with the fixed cost, which is $65,000. The resultant total cost is $155,000.

  • Probability 0.2

Totalcost=Fixedcost+Variablecost=$65,000+(200,000×$0.40)=$145,000

With a probability of 0.2, the variable cost is calculated by multiplying the total market forecast of 200,000 with the variable cost $0.40. The product is added with the fixed cost which is $65,000. The resultant total cost is $145,000.

  • Probability 0.1

Totalcost=Fixedcost+Variablecost=$65,000+(200,000×$0.35)=$135,000

With a probability of 0.1, the variable cost is calculated by multiplying the total market forecast of 200,000 with the variable cost $0.35. The product is added with the fixed cost which is $65,000. The resultant total cost is $135,000.

High-tech:

  • Probability 0.9

Totalcost=Fixedcost+Variablecost=$75,000+(200,000×$0.40)=$155,000

With a probability of 0.9, the variable cost is calculated by multiplying the total market forecast of 200,000 with the variable cost $0.40. The product is added with the fixed cost which is $75,000. The resultant total cost is $155,000.

  • Probability 0.1

Totalcost=Fixedcost+Variablecost=$75,000+(200,000×$0.35)=$145,000

With a probability of 0.1, the variable cost is calculated by multiplying the total market forecast of 200,000 with the variable cost $0.35. The product is added with the fixed cost which is $75,000. The resultant total cost is $145,000.

Hence, from the above calculations, it can be inferred that market forecast for low-technology (which consists of hiring several new junior engineers)at the cost of $145,000 can be selected.

The product design group of Iyengar Electric Supplies,Inc., has determined that it needs to design a new series of switches.It must decide on one of three design strategies. The market forecastis for 200,000 units. The better and more sophisticated the designstrategy and the more time spent on value engineering, the less willbe the variable cost. The chief of engineering design, Dr. W. L.Berry, has decided that the following costs are a good estimate of theinitial and variable costs connected with each of the three strategies:a) Low-tech: A low-technology, low-cost process consisting ofhiring several new junior engineers. This option has a fixedcost of $45,000 and variable-cost probabilities of .3 for $.55each, .4 for $.50, and .3 for $.45.b) Subcontract: A medium-cost approach using a good outsidedesign staff. This approach would have a fixed cost of $65,000and variable-cost probabilities of .7 of $.45, .2 of $.40, and .1 of $.35.c) High-tech: A high-technology approach using the very…
