Suad Alwan, the purchasing agent for Dubai Airlines, is interested in determining what he can expect to pay for airplane number
4 if the third plane took 20,000 hours to produce. What would Alwan expect to pay for plane number 5? Number 6? Use an 85% learning curve and a $40-per-hour labor charge.
1 answer:
Answer:
Alwan expect to pay for airplane 4= $747818.48
Explanation:
given data
expect to pay airplane = 4
3rd plane produce = 20,000 hours
learning curve = 85%
solution
As here logarithmic approach allow get labor for any unit, TN, as
TN = T1(Nb)
here TN is time for the Nth unit and T1 is hours to produce the first unit
so
b = (log of the learning rate) ÷ (log 2) = slope of the learning curve
so
T3 = T1(3log(0.85)÷log2)
so we get
So Alwan expect to pay for airplane 4 = $747818.48

Solution:
Given Information,
Heat input is ( ) = 5.5 ×
Btu/h
Combustion efficiency of the boiler () = 0.7
Combustion efficiency after turn up () = 0.8
Operation Hour (t) = 5200h
Unit cost (c) =
Calculate heat output from the boiler =
x
= 5.5 x x 0.7
= 3.85 x Btu/h
Calculate the heat input to the boiler after the tune-up
=
/
= 3.85 x / 0.8
= 4.8125 x Btu/h
Calculate the saved energy after the tune-up
=
-
= 5.5 x - 4.8125 x
Btu/h
= 0.6875 x Btu/h
Calculate the annual energy saving ( )
=
x t
= ( 0.6875 x Btu/h ) ( 5200 hr/yr)
= 3575 x Btu/h
Calculate the annual cost saving
Annual cost saving = x Unit cost
= 3575 x Btu/h x
= 82225
