This paper presents a methodology, Conjoint-HoQ, which is meant to provide an improvement over the current House of Quality (HoQ) tool. The improvement comes in the form of quantitative technical information – replacing the qualitative nature of the current HoQ – through integration of conjoint analysis into the HoQ framework. The steps of the ConjointHoQ method are presented in detail with an ...

Conjoint analysis is a family of techniques that originated in psychology and later become popular in market research. The main objective in conjoint analysis is to measure individual’s or population’s preferences on a set of options that can be described by parameters and their levels. Here we consider choice based conjoint analysis, where the preferences of the people are obtained from choice...

This study provides evidence that the out-of-sample predictive performance of conjoint analysis can be improved by measuring and modeling the uncertainty of preference statements. Preferences are measured in terms of rating scores for products, while uncertainty is considered as an indicator of the stability of preferences. Uncertainty is measured in six different ways and for each of these mea...

Choice-based conjoint analysis builds models of consumer preferences over products with answers gathered in questionnaires. Our main goal is to bring tools from the machine learning community to solve this problem more efficiently. Thus, we propose two algorithms to quickly and accurately estimate consumer preferences.

AIM the aim of this study is to measure acceptance of a specific functional food: apple (fruit) leather, based on organoleptic characteristics and to identify consumer types and preferences for natural additives which increase the product's functionality and meet current nutritional needs. MATERIALS AND METHODS a sample of 800 consumers provided an evaluation of apple leather in terms of acce...
