Concept explainers
a)
To estimate: The amount of time needed to complete the fifth plane.
Introduction: Learning curve is referred as the cost curve, experience curve, efficiency curve or productivity curve. The leaving curve gives information about the cost, efficiency, productivity and performance of an organization.
b)
To estimate: The amount of time needed to complete first five planes.
Introduction: Learning curve is referred as the cost curve, experience curve, efficiency curve or productivity curve. The leaving curve gives information about the cost, efficiency, productivity and performance of an organization.
c)
To estimate: The amount of time needed to complete all 18 planes.
Introduction: Learning curve is referred as the cost curve, experience curve, efficiency curve or productivity curve. The leaving curve gives information about the cost, efficiency, productivity and performance of an organization.

- Suad Alwan, the purchasing agent for Dubai Airlines, has determined that the third plane took 20,000 hours to produce. Using an 80% learning curve and a $40-per-hour labor charge, he wants to determine the cost of the four additional planes. a) Time required for the fourth unit = 18,231 hours b) Cost of the fourth unit = ? dollars (round to the nearest whole number)arrow_forwardGiven the following information from an assembly task: First cycle time: 35 seconds Learning rate of 90% a. Determine the predicted performance time of the 200th b.

- Suad Alwan, the purchasing agent for Dubai Airlines, has determined that the second plane took 18,000 hours to produce. Using an 85% learning curve and a $35-per-hour labor charge, he wants to determine the cost of the six additional planes. Part 2 Time required for the sixth unit = 13900 hours (round your response to the nearest whole number). Part 3 Cost of the sixth unit = 486500 dollars (round your response to the nearest whole number). Part 4 Time required for the seventh unit = enter your response here hours (round your response to the nearest whole number). Part 5. Cost of the seventh unit?arrow_forwardIn yuyox ltd the first 71 units takes 92 hours to be produced where learning curve is 83% , calculate how much time it will take to produce 568 units using the wrights model ?arrow_forwardAn assembly operation has a 90 percent learning curve.
