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 available. 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.

Required:
Compute the values for her.

Respuesta :

Answer:

Time required for 1st pillar is "716 person/hr" and for 25th pillar is "120 person/hr".

Explanation:

Time for the 1st pillar will be:

⇒  [tex]T(8)= T(1)\times \frac{8 \ log (0.68)}{log \ 2}[/tex]

      [tex]225=T(1)\times 0.314432[/tex]

    [tex]T(1)=\frac{225}{0.314432}[/tex]

    [tex]T(1)=716 \ person/hr[/tex]

Time for the 25th pillar will be:

⇒  [tex]T(25)=761\tines \frac{25 \ log(0.68)}{log \ 2}[/tex]

    [tex]T(25)=120 \ person/hr[/tex]
