Sensitivity analysis incorporating fuzzy evaluation for scaling constants of multiattribute utility functions
A multiattribute utility function can be represented by a function of single-attribute utility functions if the decision maker’s preference satisfies additive independence or mutually utility independence. Additive independence is a preference condition stronger than mutually utility independence, and the multiattribute utility function is in the additive form if the former condition is satisfi...
متن کاملConstructing Multiattribute Utility Functions for Decision Analysis
A fundamental step in decision analysis is the accurate representation of the decision maker’s preferences. When the decision situation is deterministic, each alternative leads to a single prospect (consequence). A prospect may be characterized by one or more attributes, such as health state and wealth. A value function that ranks the prospects is sufficient to rank order the decision alternati...
متن کاملOne-Switch Independence for Multiattribute Utility Functions
Assessment of multiattribute utility functions is significantly simplified if it is possible to decompose the function into more manageable pieces. Utility independence is a powerful property that serves well for this purpose, but if it is not appropriate in a given situation, what options does the analyst have? We review some possibilities and propose a new independence assumption based on the...
متن کاملDirectional Decomposition of Multiattribute Utility Functions
Several schemes have been proposed for compactly representing multiattribute utility functions, yet none seems to achieve the level of success achieved by Bayesian and Markov models for probability distributions. In an attempt to bridge the gap, we propose a new representation for utility functions which follows its probabilistic analog to a greater extent. Starting from a simple definition of ...
متن کاملA Class of Multiattribute Utility Functions
A function u(z) is a utility function if u′(z) ≥ 0. It is called risk averse if we also have u′′(z) ≤ 0. Some authors, however, require that u(i)(z) ≥ 0 if i is odd and u(i)(z) ≤ 0 if i is even. The notion of a multiattribute utility function can be defined by requiring that it is increasing in each variable and concave as an s-variate function. A stronger condition, similar to the one in case ...
