Abstract
During the months of May and June of 2002, interviews and surveys were conducted with over 30 high‐level private, public, academic and non‐profit sector leaders from around the world to discuss the development and impact of regional e‐commerce initiatives. Three pioneers in this arena were analyzed: the Association of Southeast Asian Nations (ASEAN), Asia‐Pacific Economic Cooperation (APEC) and the European Union (EU). The motivation, objectives, design, structure and implementation of their respective e‐commerce programs were explored, with an eye toward uncovering the visible and invisible challenges and opportunities. This paper presents a set of high‐level principles which guided and influenced these initiatives and that can serve as a reference for other organizations considering regional e‐commerce needs.

Abstract
Addresses the problem of matching two fuzzy sets. Proposes a matching method that considers the extent to which both fuzzy sets have the same meaning. For a given degree of similarity between two sets, the same meaning decreases as the fuzziness increases and, in particular, for equal fuzzy sets the degree of matching is a function of the fuzziness only. A complete matching of two sets is obtained only when they are equal and crisp. Finally, the inverse problem is studied, of characterizing one of the sets used in the match when knowing the other set and the result of the matching.

Abstract
Purpose
This study aims to research the usage of virtual reality as a tool to train employees in a changeover process in a company, and if it guarantees the same level of quality. Moreover, another goal is to understand how it can influence the machines’ availability, reducing the number of hours a machine is stopped to perform training sessions.
Design/methodology/approach
To achieve the goals proposed, the action research strategy was used. After defining the context and purpose, two full cycles were applied, composed by five activities: diagnosis, action planning, action taking, action evaluation and specify the learning.
Findings
The results are extremely satisfactory. On the one hand, it can be concluded that virtual reality is a reliable training tool, guaranteeing proper training to the employees. On the other hand, based on the previous point, the researchers were able to conclude that it is possible to increase machines’ availability, reducing by 50% the time needed to have the machines stopped to run a changeover training.
Originality/value
To the authors’ knowledge, this is the first study to use the action research strategy to develop a virtual reality simulation as a training tool for machines’ changeover in the automotive industry.
