This paper studies conjoint measurement models tolerating intransitivities that closely resemble Tversky’s additive difference model while replacing additivity and subtractivity by mere decomposability requirements. We offer a complete axiomatic characterization of these models without having recourse to unnecessary structural assumptions on the set of objects. This shows the pure consequences ...

This paper proposes a new framework to solve the surprise examination paradox. I survey preliminary the main contributions to the literature related to the paradox. I introduce then a distinction between a monist and a dichotomic analysis of the paradox. With the help of a matrix notation, I also present a dichotomy that leads to distinguish two basically and structurally different notions of s...

In today's highly competitive environment, where sources of product and processbased competitive advantage are quickly imitated by competitors, it is becoming increasingly difficult to differentiate on technical features and quality alone. Companies may overcome this problem by incorporating the ‘voice of the customer’ into the design of new products and focusing on customer value, thereby offe...

PURPOSE Metastatic breast cancer (MBC) patients are treated with a variety of regimens with differing side effects that can reduce the patients' quality of life. This study assessed the willingness to pay (WTP) to avoid side effects related to MBC treatment using conjoint analysis. METHODS An online, self-administered conjoint analysis survey of US adult female MBC patients was conducted to e...

BACKGROUND Several attempts have been made to evaluate patients' concerns with respect to postoperative recovery. To identify aspects of postoperative recovery relevant to patients, several methodological and statistical approaches have been used. One of the first to provide useful information was Fredrick Orkin who used conjoint analysis. This methodology is usually performed by market researc...

We propose a general framework for adaptively designing choice-based conjoint questionnaires at the individual level. This framework uses complexity control to improve the robustness of the conjoint designs to response error and links the informativeness of conjoint questions to the Hessian of the loss function minimized in partworth estimation. It formalizes and generalizes several methods rec...

Communication and information technologies are adding new capabilities for rapid and inexpensive customer input to all stages of the product development (PD) process. In this article we review six web-based methods of customer input as examples of the improved Internet capabilities of communication, conceptualization, and computation. For each method we give examples of user-interfaces, initial...
