Outranking methods propose an original way to build a preference relation between alternatives evaluated on several attributes that has a definite ordinal flavor. Indeed, most of them appeal the concordance / non-discordance principle that leads to declaring that an alternative is “superior” to another, if the coalition of attributes supporting this proposition is “sufficiently important” (conc...

In the context of multiple attribute decision making, preference models making use of reference points in an ordinal way have recently been introduced in the literature. This text proposes an axiomatic analysis of such models, with a particular emphasis on the case in which there is only one reference point. Our analysis uses a general conjoint measurement model resting on the study of traces i...

Both extensions modify the axioms of Lute and Tukey for additive conjoint measurement. The first yields a theory for more than two coordinates. The main problem is to find a weak generalization of the cancellation property; the one suggested is weaker than Krantz’s generalization. The second extension weakens the solution-of-equations axiom, which has been justly criticized as too strong for mo...

In the last decades the use of regression-like preference models has found widespread application in marketing research. The Conjoint Analysis models have even more been used to analyze consumer preferences and simulate product positioning. The typical data structure of this kind of models can be enriched by the presence of supplementary information observed on respondents. We suppose that rela...

Suppose that entities composed o f two independent components are qualitatively ordered by a relation that satisfies the axioms o f conjoint measurement. Suppose, i n addition, that each component has a concatenation operation that, together either with the ordering induced on the component by the conjoint ordering or with its converse, satisfies the axioms o f extensive measurement. Without fu...

Understanding the experiences of elderly rural couples in accessing health services can assist nurses and other health professionals in their roles as advocates, service providers, educators, programme planners, and policy makers. In this paper, Frances Racher explores phenomenology as methodology, and its fit with the unstructured conjoint interview as method, in planning for a study to seek k...

INTRODUCTION Conjoint nerve root is embryological nerve root anomaly mainly involving lumbosacral region. The anomalous roots present primarily as a bifid, conjoined structure arising from a wide area of the dura. Because of their size and attachment to surrounding structures, they are uniquely susceptible to trauma. The effects of compression and entrapment are amplified in the presence of ste...

ATTRIBUTE IMPORTANCE WEIGHTS IN CONJOINT ANALYSIS: BIAS AND PRECISION Sanjay Mishra, Washington State University U. N. Umesh, Washington State University Donald E. Stem, Jr., Washington State University ABSTRACT Consumer researchers have used conjoint analysis to evaluate the importance of an attribute in forming preferences. Although past researchers have tested the validity and reliability of...

Conjoint analysis is one of the mostly used methods in the analysis of preferences and the prediction of choices. Today, most applications of conjoint analysis use paired comparisons. Paired comparisons on a graded scale are a substantive element of the adaptive conjoint analysis (ACA), a computer supported procedure that is predominantly used in marketing research. Contrasting this heavy appli...

Based on a general framework for conjoint measurement that allows for intransitive preferences, this paper proposes a characterization of “strict concordance relations”. This characterization shows that the originality of such relations lies in their very crude way to distinguish various levels of “preference differences” on each attribute.
