A Web-Based Consensus Support System Dealing with Heterogeneous Information.

The study of the consensus is an important research field in Decision Making. Several authors have addressed the analysis of the consensus processes from different points of view (techniques, models, information domains, etc.), In this contribution we show a novel web application about a consensus support system to carry out consensus reaching processes with heterogenous information, i.e., the decision makers may use different information domains (particulary, numerical, interval-valued and linguistic assessments) to express their opinions. The software application has the following main characteristic: i) it automatizes virtual consensus reaching processes in which experts may be situated in different places, ii) experts may use information domains near their work areas to provide their preferences and, iii) it is able to run on any computer and operating system. This application may be seen as a practical development of a theoretical research on the consensus modelling. It could be used by any organization to carry out virtual consensus reaching processes.
