Abstract:

For the problem of group evaluation in complex uncertain environments, an interval rough number is used to characterize experts’ preferences, and a stochastic simulation integrated algorithm is proposed based on the G1 method combined with Monte Carlo simulation techniques. Firstly, the weighting coefficients are simulated by random sampling and the weighting of experts are determined based on ordinal correlation and interval rough number closeness. Secondly, the final weights of indicators can be obtained by combining all the experts’ opinions, and they are linearly aggregated with the pre-processed indicator values to obtain the comprehensive evaluation value of one simulation, which can be used to assess the advantages and disadvantages of the evaluated objects. Through full simulation, the preference ratio matrix is calculated, and the probability ranking with the probability of superiority is derived from it, which makes up for the deficiency of absolute ranking in the uncertain information environment. Finally, the effectiveness of the method is illustrated by an example and the advantages of the method are described in comparison with the existing methods.
