\n\t\t\t\t\t\t\t\t\tExpert methods according to [86] utilize the knowledge and practical experience of experts in the relevant field to obtain: estimates of immeasurable quantities, estimates of data that are not available and whose acquisition would be disproportionately difficult, estimates of future developments (states), proposals for creative solutions, etc. A typical use of experts in this set of methods is for narrow, specialized problems, or especially for general, complex, and intricate problems (i.e., those that are complex, poorly structured, weakly formalized, unique and non-repeatable, with a lack or complete absence of objective qualitative information, etc.) [86]<\/a>. The expert survey proceeded in the following phases:\n\n
  1. Selection of experts.<\/li>
  2. Collection of expert statements.<\/li>
  3. Evaluation of expert statements.<\/li> <\/ol> The quality of expert selection directly influences the quality of the results obtained from the analysis. The decisive factors are the number of experts (i.e., for statistical significance of the results) and their relevant qualities (e.g., competence, creativity, relationship to the topic, conformity, analytical thinking and breadth of thought, constructiveness, self-criticism, tolerance) [86]<\/a>. The determination of the number of experts and the selection of appropriate qualities are parameters dependent on the method chosen for obtaining expert statements and, as such, also affect the costs of the analysis, both financial and time-related.\nThe collection of expert statements can occur in various ways, as described in [86]<\/a>, based on: the method of communication between organizers and experts, the level of communication between experts during the expert survey, the repetition of information gathering, and the degree of standardization.\n\nFor the purposes of the dissertation, a multi-stage Delphi method was chosen.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
