Heterogeneous data are those of various formats and collected from various sources. Such data usually are incomplete and inaccurate, which makes them difficult to process and cluster. In this work, a method for cluster analysis of heterogeneous data using the provisions of fuzzy logic is presented. The simulation models for representing a candidate for a vacant position, which is characterized by heterogeneous data, are provided. The apparatus of algebraic systems has been used to develop simulation models. A method for determining the membership function of fuzzy sets using a probabilistic approach as the most effective when working with heterogeneous data, is described in detail. An example is given of the formation of a base of logical rules for selection of classification features in a set of heterogeneous data of the personnel reserve of a manufacturing enterprise. The selected classification features allow for further accurate and efficient verification and evaluation of information about candidates for a vacant position. The proposed method of cluster analysis of heterogeneous data can be applied in various subject areas that involve the use of incomplete and inaccurate data, for example, socio-economic, technical, and biological systems.
