An improved TOPSIS-ANP composite shielding material performance evaluation method based on gray relational projection algorithm

The performance of shielding materials directly affects the radiation protection effect and plays a very important role in process ensuring safety nuclear energy. Therefore, this paper introduces evaluation composite materials, which firstly points out disadvantages traditional TOPSIS method, proposes weighted projection model under extended theory, clarifies principle dimensional reduction algorithm implementation. Secondly, also basic assumption non-linear mapping relationship between index dimensions, scientifically determines weight system based on ANP structural model, so as to form an improved TOPSIS-ANP material method gray relational with coupling characteristics. empirical results show that proposed is consistent conclusion ratio lead-boron-polyethylene optimized genetic algorithm, proves effectiveness paper. Meanwhile, more comprehensive, efficient scientific well, has good promotion prospects application advantages.
