Please help me with these questions. Thank you very much!!
Attribute Swung Rank Rate Weight from Worst to Best (i) 0 Life Span 100 (ii) KL = Price (vii) 60 (iii) Kp = Power 90 (iv) Kpw = Brand 48 (V) KB = Operating Weight 22 (vi) Kow = b-i) = ?, b-ii)=? , b-iii)=?, b-iv)=?, b-v)=?, b-vi)=?, b-vii)=? Note: You don't need to copy the table, calculate and write it with proper labelling. (c) Rick carefully examined the five attributes and narrowed down to life span and price. He is willing to pay $1,880 for an extra half year of life span. Calculate weights KL and Kp for attribute life span and price respectively. With the weights calculate overall utilities and recommend which compactor he should select from A, B, or C. Why? Vehicle Life Span P=Price ($) Attribute UTILITY Model (years) (P) (L) A 14.7 375400 Price (P) Up(X*) = 1 Up(X-) = 0 B 12 425150 Life Span (L) | UL(x+) = 1 UL(X- ) = 0 C 18 535890Atkinson Landfill Co. is planning to buy a landfill compactor, landfill compactor is a heavy compacting machine with a large unit line load, and it is mainly used for compaction of landfill materials, which can reduce the volume of materials in the landfill. They assigned this job to Mr. Rick. Suppose that Rick is risk-neutral with respect to each attribute and he has the following values/utilities for life span, price, power, brand and operating weight: Compactor Life Span P=Price ($) Power (Horse Brand Operating Weight (Kg) (years) (L) [P) Power) (PW) (B) (OW) A 14.7 375400 350 BOMAK 22900 B 12 425150 650 ZHANTOI 25400 C 18 535890 750 CATT 28500 UTILITY TABLE Attribute Operating Weight Wow(28500Kg) = 1 |Vow(25400Kg) = 0.7350 Wow(22900Kg) = 0 Brand UE(CATT) =0.6750 | UB(ZHANTOI) = 0 U=(BOMAK) = 1 Power Upw(750) = 1 Upw(350) = 0 Price Up(X+) = 1 Up(X-) = 0 Life Span UL(x+) = 1 UL(X-) = 0 Note that, x* and x- represent the best and the worst values of the given attribute x, respectively. Using the additive utility model and assume that for Rick (weight related to Power) Kpw= 0.0825, (weight related to Life Span) KL = 0.2620, Price is four times as important as Power, Operating Weight is 0.5 times as important as Life Span. a) Find Rick's overall utilities for the three compactors? Which one should he chose, why? b) Recall, that the swing-weighting approach can be used in virtually any weight-assessment situation. A Swing-weight assessment table with Rates assessed is given below: Find the missing details in table from i to (vii). Then re-calculate overall utilities of compactors A, B and C? Which one (among A, B, and C) should be chosen with these new overall utilities and why
