Question

Rose is a project manager at the civil engineering consulting firm of sands, gravel, concrete, and waters, Inc. She has been collecting data on a project in which concrete pillars were being constructed, however not all the data are avaliable. She has been able to find out that the 8th pillar required 225 person hours to construct and that a 68% learning curve applied. She is interested in calculating the time required to construct the 1st and 25th pillars. Compute the values for her.

Answer 1

Given that 8th pillar requires 225 person hours to construct and a 68% learning curve is applied. Below is the formula used to calculate the time required to construct 1st pillar: + 10 Here, 'b' is b= log (learning curve/100) log(2) log(0.68) log(2)

Calculate the time required to construct 1st pillar: 225 log(0.68) 10 log(2) = 810.17 person/hour Therefore, the time required to construct 1st pillar is 810.17 person/hour. Calculate time required to construct 25th pillar: 0.68) Tas =Tx 25 = 810.17 x 25 Toga = 135.14 person /hour Therefore, the time required to construct 25th pillar is 135.14 person /hour
