Question
An analyst is assessing a DM's utility function for combined present value of cost COST , in units of [10 8 $], ranging from 0
An analyst is assessing a DM's utility function for combined present value of cost COST, in units of [108 $], ranging from 0 to 5, and for annual total vehicle travel time TVTTann,, in units of [106 veh-hrs], ranging from 0 to 20.
- What are considered the best and worst paired values of (, )? Your answer should contain two elements, one showing best values of (, ) and a second showing worst values of (, ).
For parts b-d, the analyst wishes to use a function:
(, ) = ((5.0 )/5.0 )1 + (1 )((20.0 )/20.0)2
where the values are exponents.
- What are the utilities of the values you reported in part a? Show your work.
- The analyst has determined that the DM is indifferent between Alternative A and Alternative B:
Alternative A: Probability 0.9of incurring (, ) = (0.0, 0.0) Probability 0.1of incurring (, ) = (5.0, 20.0)
Alternative B: Probability 1.0of incurring (, ) = (0,20.0)
What is the value of wfor this DM? Show your work.
- The analyst has determined that the DM is also indifferent between Alternative C and Alternative D:
Alternative C: Probability 0.5of incurring (, ) = (0.0, 20.0) Probability 0.5of incurring (, ) = (5.0, 20.0)
Alternative D: Probability 1.0of incurring (, ) = (1.5, 20.0)
What is the value of 1for this DM? Show your work.
