- Suppose a manufacturer of copiers has concluded that a 70 percent learning curve applies to the time a beginning service technician takes to install copy machines. Use the Learning Curve Excel template to answer the following questions: If the time required to install the first copy machine is estimated to be five hours, what is an estimate of the time required by a new technician to install the second and third copiers? Round your answers to one decimal place. For x = 2 it takes hours For x = 3 it takes hours If the learning rate changes to 65 or 95 percent, what is an estimate of the time required by a new technician to install the second and third copiers?

- Cumulative Average-Time Learning CurvePohlman Company makes aircraft engines. Pohlman has noticed that, in general, each new engine design is subject to an 80 percent learning rate. Assume that the first unit produced takes500 hours, and direct labor is paid an average of $30 per hour. Required:1. Set up a table with columns showing: the cumulative number of units, cumulative average time per unit in hours, and cumulative total time in hours. Show results by row for total pro-duction of: one engine, two engines, four engines, eight engines, sixteen engines, and thirty-two engines. (Round hour answers to two significant digits.) 2.

- The personnel manager of Powerwest Inc. wants to estimate the direct and cumulative average direct labor hours for producing 30 locomotive train units during the next year. He estimates from past experience that the learning rate is 90 percent. The production department estimate that manufacturing the first unit will take 30,000 hours. Each employee averages 200 hours per month. The production rate forecast is as follows: Month Production Rate (units) Month Production Rate (units) January 2 July 2 February 3 August 4 March 2 September 3 April 4 October 3 May 3 November 1 June 2 December 1 Show/explain step by step, so I fully understand the process. How many direct hours are required to produce the 30th unit? How many total hours are needed to produce all 30 units? What is the maximum number of employees required next year? If the learning rate were to change to 0.85, what would be the impact on the total hours…arrow_forwardA manufacturer of diesel locomotives needs 50,000 hours to produce the first unit. Based on past experience with similar products, the rate of learning is 80 percent. a. Use the logarithmic model to estimate the direct labor required for the 40th diesel locomotive and the cumulative average number of labor hours per unit for the first 40 units. b. Draw a learning curve for this situation.arrow_forwardRecall from the lecture that the functional form for a learning curve (LC) is y = axb where y is time to produce the most recent unit and x is the cumulative production. Here, the coefficient a is the time required to produce the first unit. The exponent (b), which is negative value, represents the learning rate. Consider a production system that needs to produce its main product based on 75% learning curve. It was measured that it took 180 minutes to produce the first unit from this production system. A. How much time would it take to produce the 20th unit? Show your work. B. Suppose the 20th unit was just produced and customer placed order of 10 more units. How much time would it take to produce those 10 more units? Use definite integral method with adjusted range. Show your work. C. What is the production rate for producing 10 units in the above question (#1.B) in the dimension of [parts/hour]? Show your work.arrow_forward
