Review article

The article presents a comparative analysis of three popular methods for determining the weight coefficients of contributing factors: the direct placement method, the ranking method, and the method of analyzing hierarchies. Advantages and disadvantages of each method are analyzed. A technique that allows combining the advantages of these methods is proposed. Procedures are described based on ranking factors with subsequent introduction of corrections to the weighing coefficients calculated basing on the ranking. The rules for introducing corrections have been formulated. An algorithm for implementing the proposed method is developed, which is illustrated with a model example.
