On (Measurable) Multiattribute Value Functions: An Expository Argument

In this note, we provide an easy-to-understand introduction to strength-of-preference measures in the context of deterministic multiattribute value assessments, focusing on what they are and why they matter. Though these issues are well understood by some decision analysts, we believe that many do not understand or appreciate the role of strength-of-preference assumptions when assessing or interpreting multiattribute value functions. The note is structured around an argument between the two authors that took place when reviewing applications of multiattribute value functions.
