Abstract:

The issue of comprehensive evaluation widely exists in various fields such as society, military, economy, and management, and the conclusions of comprehensive evaluation serve the goals of scientific decision-making. Aiming at the problem of three-dimensional dynamic evaluation considering time dimension, object dimension and index dimension at the same time, it points out the application disadvantages of the traditional TOPSIS method, puts forward a three-dimensional space combined weight projection model under the extended TOPSIS theory, and expounds its projection dimension reduction principle and algorithm implementation in this paper. On this basis, it is assumed that the index dimension has a nonlinear mapping relationship and the design idea of chaotic system are introduced. ANP structure model and CPSO optimization algorithm are selected to determine the object dimension and time dimension weight of the index system, and the final three-dimensional spatial combination weight and evaluation ranking results are calculated. The empirical results show that in terms of accuracy, the optimal fitness of CPSO algorithm is -1.344, better than that of SAG algorithm - 1.032, and avoids the defect of reverse optimization. In terms of convergence, CPSO shows a significant gradient decrease around the 5th generation, with a convergence speed three times that of PSO, while the EGA algorithm had relatively poor stability during the convergence process. Empirical research shows that the dynamic comprehensive evaluation model proposed in this paper can better solve the problem of three-dimensional spatial combination and weighting. Compared to PSO, SGA and EGA,CPSO has the advantages of global optimization of weights, fast search speed, simple weight determination method, and the comprehensive evaluation conclusion has strong credibility.
