Making Hard Decision with decision tools - 15.14 in 2^nd edition

Continuing Problem 15.13, the computers are described as follows:

A - Price: $998.95 Expected number of days in the shop per year: 4

B - Price: $1300.00 Expected number of days in the shop per year: 2

C - Price: $1350.00 Expected number of days in the shop per year: 2.5

D - Price: $1750.00 Expected number of days in the shop per year: 0.5

The computer will be an important part of your friend's livelihood for the next two years (After two years, the computer will have a negligible salvage value.) In fact, your friend can foresee that there will be specific losses if the computer is in the shop for repairs. The magnitude of the losses are uncertain but are estimated to be approximately $180 per day that the computer is down.

A - Can you give your friend any advice without doing any calculations?

B - Use the information given to determine weights kp and kr, where r stands for reliability. What assumptions are you making?

C - Calculate overall utilities for the computers. What do you conclude?

D - Sketch three indifference curves that reflect your friend's trade-off rate between reliability and price.

E - What considerations other than losses might be important in determining the trade- off rate between cost and reliability?
