Due to the funding scale and complexity of lubricant regenerative technology, the selection of recycling technology and policy for waste lubricant oil can be viewed as a multiple-attribute decision process that is normally made by a review committee with experts from academia, industry, and the government. This study aims to provide a systematic approach towards the technology selection, in whi...

Purpose – To critically review the use of Delphi techniques in qualitative research for utilising ‘expert’ opinions and to explore through a detailed example, how Policy Delphi can be used by hospitality researchers as an alternative to the more widely used Normative Delphi. Design/methodology/approach – This paper reflects on the research methodology of a project that explored organisational c...

The Delphi method is recommended for exploratory research in emerging research areas. Despite earlier suggestions for using the Delphi method for theory creation, few analytical tools are provided for this purpose. However, Grounded Theory is especially devoted to creating theories from qualitative data. This paper describes an enhanced Delphi method which integrates data analysis techniques fr...

This paper discusses the notion of collective intelligence through the application of the Wideband Delphi method as a way to obtain convergence among a group of experts. The specific application is the definition and calibration of cost estimation models that use data collected from experts as part of their calibration. Convergence is important in this case because companies need to commit to c...

Delphi multi-round survey is a procedure that has been widely and successfully used to aggregate experts’ opinions about some previously established statements or questions. Such are usually expressed as real numbers commentaries. The evolution of the consensus can be shown by an increase in agreement percentages, decrease number comments made. A reached when this percentage exceeds certain set...

Many factors related to river run-off are vague, subjective and difficult to quantify. The fuzzy logic method is very useful for such problem solving approach such as small hydro power generation. The rule base and membership functions have a great influence on the performance and efficacy of the plant and also to optimize the small hydro power generation in the high altitude region particularl...

Wewished to further understand Transnational Knowledge Transfer (TKT) in a not-for-profit context. To accomplish this, we explored, verified, and mapped out the key factors affecting TKT using a fourcomponent framework in the context of publically funded knowledge transfer (KT) projects. The Delphi technique was used to explore, identify, and verify the relevant key factors; 24 major factors we...

Despite having an important role supporting assessment processes, criticism towards evaluation systems and the categorizations used are frequent. Considering the acceptance by the scientific community as an essential issue for using rankings or categorizations in research evaluation, the aim of this paper is testing the results of rankings of scholarly book publishers’ prestige, Scholarly Publi...

A set of statements was developed by the authors utilizing the literature on the definition and classification of cholesteatoma. A questionnaire was sent to the members of the EAONO, inviting them to state if they are in agreement with each of the statements and if not, then to provide comments or suggestions for revision. Responses were evaluated and modified using online questionnaire and sur...

As the volume and scale of urban expressways continue to increase, renewal remains a concern for development. The decision-making an expressway need be endowed with new concepts adapt rapid development cities. Nevertheless, in addition considering road factors such as facility conditions, driving environmental protection, existing evaluation system lacks comprehensive consideration that improve...
