Multiattribute evaluation of alternatives for the disposition of surplus weapons-usable plutonium on the base of fuzzy sets has been made.

When choosing a portfolio of projects with a multi-attribute weighting model, it is necessary to elicit trade-off statements about how important these attributes are relative to each other. Such statements correspond to weight constraints, and thus impact on which project portfolios are potentially optimal or non-dominated in view of the resulting set of feasible attribute weights. In this pape...

This is a summary of the author’s PhD thesis, defended on 8 October 2007 at the University of Luxembourg and the Faculté Polytechnique de Mons, under the joint supervision of Raymond Bisdorff and Marc Pirlot. The thesis is written in English and is available from the author upon request. The work is situated in the field of Multiple Criteria Decision Analysis (MCDA). It mostly deals with what w...

Increasingly, the design of successful new industrial products is related to careful market assessment. Traditionally, managers and researchers have studied their markets by examining a small number of product attributes that are common across a range of informed respondents. In many ways, these techniques fail to meet the challenges posed by today's often heterogeneous, highly competitive, fas...

One of the key challenges of current day electronic procurement systems is to enable procurement decisions transcend beyond a single attribute such as cost. Consequently, multiattribute procurement have emerged as an important research direction. In this paper, we develop a multiattribute e-procurement system for procuring large volume of a single item. Our system is motivated by an industrial ...

This paper investigates consumer preference uncertainty in multiattribute judgment. We investigate preference uncertainty as a function of stimulus characteristics such as attribute conflict (discrepancy among the attributes of an alternative) and attribute extremity (very high or low attribute values). Following the behavioral results reported by Fischer, Luce and Jia (2000) and the simulation...

This paper presents moments and cross-moments of utility functions and measures of utility dependence. We start with an interpretation of the nth moment of a utility function, and describe methods for its assessment in practice and consistency checks that need to be satisfied for any assessed moments. We then show how moments of a utility function (i) provide a new method to determine the param...
