Delphi method application for engineering

Abstract

The authors had the idea to try to use the Delphi method for generating and evaluating projects of roofing. For this purpose questionnaires were prepared and three rounds of investigation were carried out, in which participated 30 experts as the respondents for roof installation projects evaluation. For the research a set of the parameters and sub-parameters to be assessed was selected. This set was formed as the basis from collected and summarized data by the paper's authors. The practice has shown that the Delphi method in engineering field organizers must to have a very good knowledge in the field of survey and to provide the greatest set of the possible parameters as possible. It was found that there is a large difference of the experts’ opinion what the parameters should be a priority. In order to evaluate objectively and to select the best roof design, the options have to rely on few experts’ opinion and then it is good to use their average evaluation as a basis for possible options selection.
