Cellular Automation-Based Fuzzy Simulation Model of Transportation System for Earth Rockfill Dam Construction

In consideration of the fuzziness in the transportation system for earth rockfill dam construction and the difficulties in the combination of time, space, and systematic actions in conventional simulation methods, a cellular automation based fuzzy simulation method is proposed for the transportation system. By replacement of the conventional probability distribution with the discrete fuzzy distribution, the method is suitable to the cases in which the number of data is small, or it is difficult to determine the probability distribution of the system. The method, by full use of the field knowledge and experience, uses the model of cellular automation to describe the transportation system during the construction of earth rockfill dams, and combines space, time, and systematic actions together, realizing the simulation of the transportation system visually and precisely.
