To tackle a class of grey multi-index decision problems with completely unknown attribute weighted values and interval grey number, a dynamic multi-stage decision-making method is proposed based on the grey system theory. Firstly, we presented a method for comparison of two grey numbers and identification of the attribute weighted values. Secondly, the experts expressed attribute values in internal...
To further study the properties of NGM (1,1,k) model and reduce its modeling complexity, we improve this model by putting forward a formula to solve its parameters, building an algorithm for optimizing the NGM (1, 1, k) model in terms of the least modeling error, and designing a key technology for implementation of this algorithm. The optimized NGM(1,1,k) model is built accordingly. The parameter...
The purpose of the article lies in enhancing the smoothing of original data sequence of systems. According to the theory of prior usage of new information, on the basis of the present theory of buffer operators and some existing weakening buffer operators, we established a type of new weakening buffer operators, and gave the whole proof process. The problem that there are some contradictions between...
