One of the issues which can be solved with modern systems that manage complex technical objects is the task of monitoring the modes of the control object operating. The issues can be solved by using the integral taxonomic index. The conclusion about the control object performance is made on the basis of the index value. At the same time, the index using does not allow to detect the large deviations of separate object parameters, so the development of existing approach is proposed in the work.
