L1: It takes 32,355 hours to produce the sixth ship of the LPD class at a shipyard. The learning curve rate is 85%. How long does it take to produce the seventh ship?

Answer:

It will take 31,206  hors to complete the seventh ship

Explanation:

We solve usiing the wright average model:

[tex]Y = aX^{b}[/tex]  

where:

a: hours of the first unit

X: the unit we are solving for  

b: the slope of the learning curve function

The model assumes every time the outpu is doubled the resources used are 85% of the previous phase.

Having the value for the sixth unit we first solve for the first unit and then solve for the seventh unit:

[tex]32,355 = a6^{log 0.85 / log 2}[/tex]  

a = 49,248

now we solve for the 7th unit:

[tex]Y_7 = (49,248)7^{log 0.85 / log 2}[/tex]  

31,206.47453
