Multiattribute Preference Analysis with Performance Targets

Evaluating the Benefits of Generalized Additive Representation in a Multiattribute Auction Setting

We compare the economic efficiency achieved by multiattribute auctions that use an accurate GAI modeling of preferences, with a multiattribute auction that is limited to an additive representation. We draw random GAI-structured utility functions with various internal structures, generate additive functions that approximate the GAI utility, and compare the performance of the auctions using the t...

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...

Preference ratios in multiattribute evaluation (PRIME)-elicitation and decision procedures under incomplete information

This paper presents the preference ratios in multiattribute evaluation (PRIME) method which supports the analysis of incomplete information in multiattribute weighting models. In PRIME, preference elicitation and synthesis is based on 1) the conversion of possibly imprecise ratio judgments into an imprecisely specified preference model, 2) the use of dominance structures and decision rules in d...

Decision Making with Multiattribute Performance Targets: The Impact of Changes in Performance and Target Distributions

Preference Representation for Multi-Unit Multiattribute Auctions

The problem of multi-unit multiattribute trading, though useful in practical procurement settings, has been rarely addressed in auction literature. We present a general framework to structure specifications of preferences over multi-unit multiattribute outcomes, allowing flexible tradeoffs between expressiveness and compactness of representation. Next, we use this framework to propose an auctio...
