The changes observed in complex control systems (CS) is due to regulating factors (RF) exceeding the action, of the random outside effects. The system retains its complexity, but in the general case both the separate links and their relations and interactions change. The state of the system is described by a determining set of signs ai and by a function F (Ai) specific for the system. If a comparative analysis of objects with the same function F, but with different values of ai is carried out, then the type of function F is of no importance and to each state Oj corresponds isomorphically an image-vector Rj in the multidimensional space M(i) of the sign a-,. Such is the case of the ontogenetic development of biological objects of the same species in an interval of time where the type of function F remains the same (e.g. the function of metabolism). Even in this case, however, the number of the signs a, resp. of the dimensionality in the space M(j), is usually considerable. On account of this the researchers tend to reduce this number, even when it leads to a compromise with the accuracy of the analysis. One possibility for such a compromise is the accuracy of the scale used for measuring the differences between the values of aj in the different states (moments of time).
