The article describes the worked on numerical technique for forming alternative coalitions of experts relating to solving weakly formalized problems and the results of verification of the proposed method by the example of the studying the attributes of violators in the field of physical protection of critical information infrastructure objects. The proposed methodology for conducting preliminary examination on the basis of the worked on numerical method for identifying coalitions of experts allows to perform the procedure for forming an agreed group of experts and obtaining preliminary estimates of the significance of the attributes of a violator during a single survey of experts, that significantly saves time and reduces the complexity of the expertise of objects. Using the worked on numerical method, the main and two alternative coalitions were identified. Taking into account the alternative opinion of experts allowed 31 experts to be identified as agreed upon, which more precisely determines the results of the expertise.
