| Abstract: | Due to the complexity of earthwork allocation system for the construction of high concrete face rockfill dam, traditional allocation and planning are not able to function properly in the construction process with strong randomness. In this paper, the working mechanism of earthwork dynamic allocation system is analyzed comprehensively and a solution to fuzzy earthwork dynamic allocation is proposed on the basis of uncertain factors in the earthwork allocation of a hydropower project. Under the premise of actual situation and the experience of the construction site, an all-coefficient-fuzzy linear programming mathematical model with fuzzy parameters and constraints for earthwork allocation is established according to the structure unit weighted ranking criteria. In this way, the deficiency of certain allocation model can be overcome. The application results indicate that the proposed method is more rational compared with traditional earthwork allocation. |
