Problems in the Study of the Equivalent Resistance of the Electrical Low Voltage Networks, Given the Switching Devices

The article analyzes the possibility of using R-optimal plans for the study of systems of internal power supply. The initial information about the network has some level of uncertainty. The solution to the problem under uncertainty is a set of solutions that are indistinguishable from each other. It is proposed to use the method of finding the R-optimal plan. The method is based on the relation of preference and indistinguishability of solutions in optimization problems with inaccurate models. The optimality criterion is the value ρ

(x, z). This feature appears due to the presence of errors of a regression model and specify the threshold to distinguish between valid solutions. The criterion allows to estimate the degree of influence of various factors on the value of the target function (equivalent resistance). Given the method of calculation of the optimality criterion, the test conditions of fuzzy decisions and the rationale for the assessment of the impact of various factors on the function of the goal (the equivalent resistance).
