Cross-impact analysis is a method for revising estimated probabilities of future events in terms of estimated interactions among those events. This Report presents anelementary cross-impact model where the cross-impacts are formulated as relativeprobabilities. Conditions are derived for the consistency of the matrix of relative probabilities of n events. An extension also provides a nec...

Abstract: Modern technology provides a great amount of information. But for computer monitoring systems or computer control systems, in order to have the situation in hand, we need to reduce the number of variables to one or two parameters, which express the quality and/or security of the whole system. In this paper the authors introduce the system parameter fusion principle put forward by the ...

The Delphi protocol is applied when a community of experts is required to reach a consensus and to deliver an answer. In these cases, consensus stands for reaching an agreement among the experts about what the answer should be. This consensus reaching problem has been already considered in the literature, though its automatisation remains as a challenge. Intuitively, the experts should dialogue...

BACKGROUND Assessing the accuracy of influenza epidemic periods determined by statistical models is important to improve the performance of algorithms used in real-time syndromic surveillance systems. This is a difficult problem to address in the absence of a reliable gold standard. The objective of this study is to establish an expert-based determination of the start and the end of influenza e...

This study seeks to identify a set of key indicators along with weightings for tourist attractions in Taiwan, and develop a quality management self-evaluation mechanism for tourism businesses, using an advanced integrated Analytic Hierarchy Process and Delphi (AHP-Delphi) approach derived from the supply side perspective. This research study comprises two phases: (1) Delphi method analysis that...

The Delphi method has proven a popular tool in information systems research for identifying and prioritizing issues for managerial decision-making. However, many past studies have not adopted a systematic approach to conduct a Delphi study. This article provides rigorous guidelines for the process of selecting appropriate experts for the study and gives detailed principles for making design cho...
