模糊多目標(biāo)與多路徑運(yùn)輸問題的結(jié)構(gòu)元方法研究
[Abstract]:Based on the theory of fuzzy structure element, the fuzzy transportation problem with fuzzy parameters is studied. This paper mainly studies the establishment of the model, the solution method, the process and the path selection of the multipath fuzzy transportation problem. By using the fuzzy structural element method, the weighted eigenvalue of the structure element of the fuzzy number is introduced, and the fuzzy transport model with triangular fuzzy numbers in the objective function and the constraint condition is transformed into the traditional model. The fuzzy programming method of membership function defined by objective function is used to find the feasible solution of the model, and the method is applied to the fuzzy transportation problem, which simplifies the computational complexity of the solution effectively. In this paper, we study the fuzzy multi-attribute decision making problem in which the attribute value and the weight value are triangular fuzzy number in the alternative scheme, and obtain a structure element method of fuzzy VIKOR. The triangular fuzzy number decision matrix is transformed into real number matrix by using the weighted eigenvalue of the structure element of fuzzy number, and the optimal solution of multi-attribute decision making is obtained by sort analysis. The structure element method of fuzzy VIKOR is applied to the path selection of fuzzy transportation, so that the optimal path can be selected reasonably and accurately in multipath fuzzy transportation.
