Mathematical model for selecting the optimal option of technological processes for decommissioning nuclear power facilities using the Monte Carlo method.

The paper presents diagrams and algorithms for selecting the optimal variant of technological operations for decommissioning nuclear facilities under conditions of uncertainty in the initial data. Uncertainties of expert assessments and calculated values of the initial data give rise to uncertainties in the values of indicators for the options for technological operations for the decommissioning of nuclear facilities. The choice of the optimal variant of technological operations is made on the basis of a complex indicator that combines particular indicators in the form of a linear superposition for each considered option of choosing a set of technological operations for the decommissioning of an object. The scheme for choosing the optimal option under conditions of uncertainty in the initial data uses the Monte Carlo scheme of realizing random data values, constructing histograms of a complex indicator and choosing the optimal option based on comparing the characteristics of the obtained histograms.
